Ergonomically Designed Products in the Office: The keyboard: When typing for long periods of time using an ordinarily designed keyboard, this common task can cause the uncomfortable and unnecessary stresses and strains to the user such as carpal tunnel syndrome, or stresses and strains within the hand and forearm, that can cause or, are beginning symptoms of serious, musculoskeletal disorders, and can make the keyboard an unsafe, ergonomic hazard. But not worry, the ergonomically designed Microsoft Natural Ergonomic Keyboard 4000 has re-designed the ordinary keyboard, to help relieve the unwanted strains and stresses associated with typing. An ergonomic advantage made into the design of the Microsoft Natural Ergonomic Keyboard 4000 is an added wide palm and wrist rest. The wide palm and wrist rest made into the design of the Microsoft Natural Ergonomic Keyboard 4000 allows the user to comfortably rest their palms and wrists on the keyboard while typing, which allows the user to naturally rest these body parts comfortably while typing, versus having no palm or wrist rest on the ordinarily designed keyboard, letting the user hold their hands and wrists up in an unchanging position, or rest them on an uncomfortable surface. Now, with the Microsoft Natural Ergonomic Keyboard 4000, typing for long periods of time does not restrict the user from having natural comfort and relaxation of their hard working hands and wrists, and instead increases the comfort and relaxation of typing endless essays or reports, suiting the task a little more for the user and worker. The second ergonomic advantage made into the Microsoft Natural Ergonomic Keyboard 4000 is an add-on, elevated attachment. Applying the elevated attachment onto the already, ergonomically designed and comfortable Microsoft Natural Ergonomic Keyboard 4000, helps the user avoid flexing their wrists while typing, reducing the stresses and strains that occur within the wrist because of flexing them, especially for long periods of time. With the add on, elevating accessory on the Microsoft Natural Ergonomic Keyboard 4000, the user increases the comfort of typing within their wrists, and reduces and prevents any unnecessary wrist flexing done while typing, allowing the user to experience an enjoyable and comfortable feeling while typing. The third and final ergonomic advantage applied into the design of the Microsoft Natural Ergonomic Keyboard 4000 is a split keyboard. Designing the keyboard of the Microsoft Natural Ergonomic Keyboard 4000 to be split into 2 separate parts allows the user’s arms to be naturally apart and freely separated while typing, instead of using an ordinarily designed keyboard, which places the user’s arms a little too close together, in a tight and uncomfortable position. Many users who enjoy having added comfort and flexibility while the do a simple task such as typing, will enjoy the added natural separation of the arm position and the new free and relaxed position of their arms while typing, because of the ergonomic, split keyboard design of the Microsoft Natural Ergonomic Keyboard 4000.
Disadvantages to the Microsoft Natural Ergonomic Keyboard 4000: The Microsoft Natural Ergonomic Keyboard 4000’s design was meant to “increase” comfort and “reduce” the common stresses and strains of typing, but unfortunately, the “ergonomic” design also comes with a variety of ergonomic disadvantages and design setbacks. One ergonomic disadvantage and design setback some users have experienced with the Microsoft Natural Ergonomic Keyboard 4000 is an “uncooperative” space bar. Some users have found that pressing the space bar on the supposed “ergonomic” Microsoft Natural Ergonomic Keyboard 4000, requires an increased amount of force to push down while typing, since pressing it lightly or “normally”, does not make the key function at all. Having this disadvantage within the “comfortable” Microsoft Natural Ergonomic Keyboard 4000 uses more of the user’s force to press it down for the key to function, and increases the stress of the user, since this key is consistently used throughout typing. Along with an uncooperative space bar, the Microsoft Natural Ergonomic Keyboard 4000, supposed “comfortable keyboard, has another design setback and ergonomic disadvantage within its design, which is “noisy” keys. Especially experienced within offices and workspaces, the loud and consistent noise of pressing down keys in a keyboard while typing is found to be an increased annoyance to the surrounding people of the working area and can increase the stress of fellow workers, which unfortunately some users of the Microsoft Natural Ergonomic Keyboard 4000, have found that pressing the keys of that keyboard, emits a particularly loud sound, which can cause a particularly, stressing disturbance to the worker’s surroundings. During long periods of typing with the Microsoft Natural Ergonomic Keyboard 4000, users will experience an increase in their annoyance and stress from a consistent, loud sound, instead of an increase in “comfort” and “relaxation”, and will eventually increase the annoyance and disturbance of repetitive and loud, key sounds to fellow workers, and the people surrounding them. The final ergonomic disadvantage found within the design of the Microsoft Natural Ergonomic Keyboard is the split keyboard design. Some people who are used to typing with an ordinarily designed keyboard will have difficulty adjusting to the split key section and large center buttons of the keyboard, which could eventually cause them to develop stress while using the “ergonomically” designed keyboard. Facing increased stress in the workspace or while working on long and difficult projects when using an “ergonomic” keyboard, such as the Microsoft Natural Ergonomic Keyboard 4000, simply because of its complete redesign of the ordinary keyboard sections, causing difficulty in adjustment to the workplace and household tool, can prove that maybe the smallest ergonomic disadvantage in an ergonomically designed product, can have a big impact on the user’s stress and adaptability. 2. The office chair: Sitting for long hours in an awkward or static position, can already cause stresses and strains to the user’s body, such as poor posture related stresses and strains, while adding an uncomfortable, and unsupportive office chair to sit in during those long hours, can add more stresses and strains such as back pain, or even unnecessary pressure on the thighs, sitting in an ordinarily designed, office chair. Well, suffer no more office workers, because the Aeron Ergonomic chair has added new ergonomic supports and a wide variety of adjustments to the ordinary office chair, to improve the comfort and safety of the common office and household furniture. The first ergonomic advantage made in the Aeron Ergonomic chair is the PostureFit addition to the chair design. The PostureFit design addition in the Aeron Ergonomic chair helps in naturally tilting and angling the pelvis while sitting, to prevent the user from suffering unnecessary back pain, and helps in aligning the spinal cord while the user is sitting, to prevent any unnecessary strains and stresses that can lead to eventual back pain. Now, sitting for long hours in the Aeron Ergonomic office chair does not restrict comfort for the user, and provides them with natural comfort and tilting to avoid any unnecessary back pains within the user and helps in promoting spine alignment, transforming long and droning hours in the office chair, into a comfortable, daily experience. Another ergonomic advantage found within the design of the Aeron Ergonomic office chair is the contoured back design of the chair. Adding a widely spread and tall , contoured back design on the Aeron Ergonomic office chair, helps in relieving unnecessary pressure, thus, any unnecessary stresses and strains caused by added pressure on the lower back area of the user. Instead of suffering through long periods of work in an uncomfortable office chair, workers who experience these long hours of sitting will enjoy the added comfort the Aeron Ergonomic office chair has with the wide and tall, contoured design of the back of the chair, which helps in relieving any unnecessary pressure in the lower back, and preventing any unnecessary and unneeded stresses and strains in the lower back of the user. A third ergonomic improvement made within the design of the Aeron Ergonomic office chair is the “waterfall” shape of the front of the seating area. Applying a “Waterfall” shape to the front of the seating area, relieves and prevents any unnecessary pressure within the user’s thighs, and in exchange, helps in improving the circulation within the user’s body, which can increase the concentration and alertness of the user and their task. For users and office workers who feel unneeded pressure within their thighs, or a lack of concentration and alertness, will now feel fresh, alert and focused, while feeling proper circulation within their body and the relief of any added, unnecessary pressure on their thighs, thanks to the ergonomic and comfortable “waterfall” seating design of the Aeron Ergonomic office chair. The final ergonomic design improvement made within the Aeron Ergonomic office chair is the “Pellicle” shape and design of the chair. Allowing the user’s weight to be evenly spread across their seat can help in relieving and avoiding any unnecessary pressure points on the user’s body, while also helping in releasing any unneeded body heat the user, to reduce and relieve pains, stresses and strains or fatigue the user experiences while sitting in their comfortable, Aeron Ergonomic office chair. Now it seems as if accomplishing the task of sitting in an office chair for long periods of the day while working, no longer needs to be uncomfortable or stressing for the user, by spreading the user’s weight evenly across their seat, relieving any unwanted pressure points and releasing any extra, unneeded body heat, to reduce aches, stresses and strains or fatigue the user may suffer, allowing the user to accomplish their daily tasks, comfortably and ergonomically.
Disadvantages to the Aeron Ergonomic Office chair: Along with the many ergonomic advantages and design improvements made into the Aeron Ergonomic office chair, many users and office workers have found that the “comfortable” design also comes with many ergonomic disadvantages and design setbacks. One of the ergonomic design setbacks and disadvantages some users have found within the Aeron Ergonomic office chair is the wide variety of non-functioning knobs. With the variety of adjustments and knobs added onto the Aeron Ergonomic office chair such as to improve the tilt, armrests and lumbar support for the user, have been found by some users to be non-functional, and do not change or improve the tilt, armrest and lumbar support within the user, which now, the ergonomic improvements made into the Aeron Ergonomic office chair, such as the tilt, armrest or lumbar support of the chair, may prove to uncomfortable for some users, since they cannot be adjusted or changed to suit the user. With users or office workers who find they need added lumbar support, a change in the tilt of their chair or need an adjustment within their “ergonomic” and “comfortable” chair, will not be able to improve or use the ergonomic design improvements made within their Aeron Ergonomic chair, and some may find that instead of experiencing the added comfort and support they need, which were not found in their old, ordinary, unsupportive office chair, they are experiencing an increase in discomfort from the non adjustable, ergonomic features in their new “comfortable” Aeron Ergonomic office chair. The second ergonomic disadvantage and design setback found within the Aeron Ergonomic chair is the “feel” and strength of the material of the “waterfall” design of the seat. The “waterfall” design improvement made into the Aeron Ergonomic office chair was added to the chair design to increase the blood circulation and relieve any unnecessary pressure on the user’s body, but rather than feeling added comfort and a relief of pressure, some users have experienced the opposite of that, with the hardness of the material causing some pain on the back parts of their thighs, and a feeling of the lack of circulation within their body because of the “comfortable”, “waterfall” design. The “ergonomic” design of the Aeron Ergonomic chair is in question for some users, who find that instead of experiencing the added comfort and support they need within their ordinary chair, they find that the ergonomic improvement to the Aeron Ergonomic office chair causes an increase of pain within their thighs and lack of circulation within their body, because they had believed in the “ergonomic” and “comfortable” design improvement the “waterfall” seat design was meant to improve within the typical, ordinary office chair. Another ergonomic disadvantage and design setback the Aeron Ergonomic office chair has within their design is the hardness of the lumbar support. An ordinary and typical office chair seems to have lacked any lumbar support for the user, a reason why the design of the Aeron Ergonomic office chair included an added, supposed “adjustable” lumbar support to their design, but rather than allowing users to feel increased back support while sitting for long hours in the “comfortable” Aeron Ergonomic office chair, some users have experienced and felt that the lumbar support of the chair is made of a tough and hard material that causes a sharp pain in their back area, which increases the discomfort of the office chair to the user and increases pain to the user’s back area. While using and experiencing the “ergonomic” design improvement of the adjustable, lumbar support of the Aeron Ergonomic chair design, some users have described the sharp pain in their back from the lumbar support material as the pain of an elbow pressing into their back while sitting, which not only disrupts the work of the user but, also increases the discomfort and uncomfortable feel while using a supposed “comfortable” office chair. The final design setback and ergonomic disadvantage “provided” within the design of the Aeron Ergonomic chair is the supposed “relief” of back pain within the back support design of the chair. Some users who had experienced back pain because of a lack of support within the design of their uncomfortable, unsupportive ordinary office chair, had hoped that the back support of the Aeron Ergonomic office chair would relieve their back pain, as intended, but had found that the back support only aligns the spinal cord while sitting, without providing any added relief to the user’s back pain while using the Aeron Ergonomic office chair, which can increase the stress of the worker because of the reoccurring back pain(s) they experience. Embedding the added back support of the Aeron Ergonomic chair within their design had intended not only to align the user’s spine but also relieve any unnecessary pains within the user’s back for added comfort, which, for some users, seemed to be only aligning and straightening their back , lacking to help them relieve any unnecessary back pain experienced from an unsupportive office chair, causing them added stress from their back pains to their workload, which can prove that even an intricately designed, ergonomic product, such as the Aeron Ergonomic office chair has many ergonomic design improvements which cannot necessarily be suited to any user or office worker. 3. The Handsaw: Commonly used among people or workers in the construction working environment and even in the household, the typical handsaw is a very useful tool that can pose a variety of ergonomic and safety hazards, such as a static or uncomfortable hand position, and a loss of grip of the saw handle while cutting, leading to an increased risk of serious injury to the user. Now thanks to the makers of the Bahco Ergo Handsaw System, working on a simple woodworking, hobbyist project or working at a construction site for long hours of the day, specializing in wood cutting, no longer has to be a dangerous, and uncomfortable task to complete, because of the ergonomic design improvements made into the shape and design of the Bahco Ergo Handsaw. The first ergonomic advantage made into the design of the Bahco Ergo Handsaw handle is the asymmetrical handle design. Since all products part of the “Ergo” collection of the Bahco Tool Company aims to comfortably and naturally fit the human hand to decrease vibration in the hand and arm and reduce muscle fatigue while increasing muscle relaxation, ideally, the company redesigned the typical handsaw handle, with an asymmetrical design that fits the human hand naturally, to remove and release any unnecessary pressure on the human hand while cutting, by allowing all parts of the hand to be involved while cutting with the Bacho Ergo Handsaw System, which increases the grip and hold of the tool, to reduce risk of the loss of grip leading to any possible, serious injury to the user from dangerous contact with the blade. Cutting a simple strip of wood or thick pieces of hard lumber would seem as if it was less of a chore while using the Bacho Ergo Handsaw System, because of the redesigned, asymmetrical handle that uses all of the user’s hand while gripping and cutting with the tool, to increase comfort and reduce the risk of serious injury to the user, making their daily working task or a simple woodworking project a little more enjoyable for the user. Another ergonomic advantage added onto the design of the Bacho Ergo Handsaw System is the position, tilt and angle of the handle and the blade teeth while cutting. The redesigned position, tilt and angle of the Bacho Ergo Handsaw System handle and the teeth of the blade together while cutting, reduces any added, unnecessary sawing forces for the user, and increases the efficiency of every cut made with the blade teeth, to increase the comfort and safety of the user, while reducing the amount of time needed to complete a woodworking task. With the redesigned position and alignment of the handle along with the teeth of the blade found in the Bacho Ergo Handsaw System , the comfortable design allows the user to enjoy woodworking tasks while spending a lesser amount of time to complete a simple cut and woodworking job, providing the user with added comfort and helps them in increasing their productivity and efficiency. The last ergonomic design improvement and advantage made into the Bahco Ergo Handsaw System is the material of the ergonomically designed handle. Thermoplastic Elastomer is a stretchable and comfortable material, and when made into the design of the Bahco Ergo Handsaw System handle, this material allows the proper and optimum amount of friction needed between the user’s hands, and provides the user with a warm sensation while cutting, allowing added comfort without added force from any unnecessary friction and gives the user a nice and warm sensation in their hands while cutting. Rather than having to face any unnecessary friction while cutting or experiencing an unnatural feeling and sensation while cutting, the Bacho Ergo Handsaw System allows the user to enjoy their woodworking projects without unnecessary force working towards friction, and allows the user to have a warm and comfortable sensation whiletackling hard construction projects or even a tough science fair, woodworking project.
Disadvantages to the Bahco Ergo Handsaw System: Originally made to reduce the common stresses and strains experienced in the hand and forearm while cutting while increasing the comfort and safety to the user, the Bahco Ergo Handsaw System has been found by some users to carry certain ergonomic disadvantages and design setbacks along with the “comfortable” new design. One of the ergonomic disadvantages and design setbacks experienced by some users is the stiffness of the tool while cutting. When cutting through certain pieces of wood, possibly the tougher pieces of wood, some users have found that the Bahco Ergo Handsaw System becomes more stiff to move as they cut through the wood, which could increase the force the user puts into the tool needed to cut through the different types of wood. By allowing the user to put in more force while cutting through different types of wood using the Bahco Ergo Handsaw System, this design setback increases the discomfort of the user while cutting, making an “ergonomic” and “comfortably” designed tool show a lack of adaptation to different types and thicknesses of wood. The second and final design setback and ergonomic disadvantage found within the design of the Bahco Ergo Handsaw System is a change of weight when interchanging between blades. One of the added features made into the design of the Bahco Ergo Handsaw System is allowing the user to change between different types of blades depending on the thickness and the type of wood they are cutting, however, some users have found that there is a certain change in weight of the entire tool when the blade is changed to a possibly thicker blade, thus, increasing the force of the user needed to cut an already thick and tough piece of wood , and eventually, decreasing the user’s comfort while cutting through the wood. This added feature in the Bahco Ergo Handsaw System is a very useful addition to the “ergonomically” designed tool, but, if some users find that it increases the weight of the entire tool while cutting, the interchangeable blade feature may cause more discomfort to users instead of increasing the comfort and reducing stress of using several types of saws for one project for the user, proving that an ergonomically designed tool such as the Bahco Ergo Handsaw System, may not be as useful to some users, reducing their comfort, safety and efficiency working with this tool.
The keyboard: When typing for long periods of time using an ordinarily designed keyboard, this common task can cause the uncomfortable and unnecessary stresses and strains to the user such as carpal tunnel syndrome, or stresses and strains within the hand and forearm, that can cause or, are beginning symptoms of serious, musculoskeletal disorders, and can make the keyboard an unsafe, ergonomic hazard. But not worry, the ergonomically designed Microsoft Natural Ergonomic Keyboard 4000 has re-designed the ordinary keyboard, to help relieve the unwanted strains and stresses associated with typing. An ergonomic advantage made into the design of the Microsoft Natural Ergonomic Keyboard 4000 is an added wide palm and wrist rest. The wide palm and wrist rest made into the design of the Microsoft Natural Ergonomic Keyboard 4000 allows the user to comfortably rest their palms and wrists on the keyboard while typing, which allows the user to naturally rest these body parts comfortably while typing, versus having no palm or wrist rest on the ordinarily designed keyboard, letting the user hold their hands and wrists up in an unchanging position, or rest them on an uncomfortable surface. Now, with the Microsoft Natural Ergonomic Keyboard 4000, typing for long periods of time does not restrict the user from having natural comfort and relaxation of their hard working hands and wrists, and instead increases the comfort and relaxation of typing endless essays or reports, suiting the task a little more for the user and worker. The second ergonomic advantage made into the Microsoft Natural Ergonomic Keyboard 4000 is an add-on, elevated attachment. Applying the elevated attachment onto the already, ergonomically designed and comfortable Microsoft Natural Ergonomic Keyboard 4000, helps the user avoid flexing their wrists while typing, reducing the stresses and strains that occur within the wrist because of flexing them, especially for long periods of time. With the add on, elevating accessory on the Microsoft Natural Ergonomic Keyboard 4000, the user increases the comfort of typing within their wrists, and reduces and prevents any unnecessary wrist flexing done while typing, allowing the user to experience an enjoyable and comfortable feeling while typing. The third and final ergonomic advantage applied into the design of the Microsoft Natural Ergonomic Keyboard 4000 is a split keyboard. Designing the keyboard of the Microsoft Natural Ergonomic Keyboard 4000 to be split into 2 separate parts allows the user’s arms to be naturally apart and freely separated while typing, instead of using an ordinarily designed keyboard, which places the user’s arms a little too close together, in a tight and uncomfortable position. Many users who enjoy having added comfort and flexibility while the do a simple task such as typing, will enjoy the added natural separation of the arm position and the new free and relaxed position of their arms while typing, because of the ergonomic, split keyboard design of the Microsoft Natural Ergonomic Keyboard 4000.

One of the ergonomic disadvantages and design setbacks experienced by some users is the stiffness of the tool while cutting. When cutting through certain pieces of wood, possibly the tougher pieces of wood, some users have found that the Bahco Ergo Handsaw System becomes more stiff to move as they cut through the wood, which could increase the force the user puts into the tool needed to cut through the different types of wood. By allowing the user to put in more force while cutting through different types of wood using the Bahco Ergo Handsaw System, this design setback increases the discomfort of the user while cutting, making an “ergonomic” and “comfortably” designed tool show a lack of adaptation to different types and thicknesses of wood. The second and final design setback and ergonomic disadvantage found within the design of the Bahco Ergo Handsaw System is a change of weight when interchanging between blades. One of the added features made into the design of the Bahco Ergo Handsaw System is allowing the user to change between different types of blades depending on the thickness and the type of wood they are cutting, however, some users have found that there is a certain change in weight of the entire tool when the blade is changed to a possibly thicker blade, thus, increasing the force of the user needed to cut an already thick and tough piece of wood , and eventually, decreasing the user’s comfort while cutting through the wood. This added feature in the Bahco Ergo Handsaw System is a very useful addition to the “ergonomically” designed tool, but, if some users find that it increases the weight of the entire tool while cutting, the interchangeable blade feature may cause more discomfort to users instead of increasing the comfort and reducing stress of using several types of saws for one project for the user, proving that an ergonomically designed tool such as the Bahco Ergo Handsaw System, may not be as useful to some users, reducing their comfort, safety and efficiency working with this tool.
