The combination of two Greek words-‘ergon’ and ‘nomo’ makes the word Ergonomics. The first word stands for work and the second word a natural law. So, the word suggests the science of work and its relation to the person in the workplace. The International Ergonomics Association has accepted the technical definition of ergonomics as a discipline deals with the optimization of overall human wellbeing and performance according to some definite data and principles. To put in simple words, the Ergonomics is the science of turning things a comfortable and efficient. By making things comfy, it makes the performance efficient. So at the simplest the ergonomics literally suggests the science of work. So, an ergonomist always takes care of how the work can be better done in suitable working condition. Though Ergonomics is normally considered in relation to the products. But, it can be similarly useful in the device of services and processes. Ergonomics helps to define how the product is used, how it fulfills your needs, and most significantly if you wish to have it or not.
Ergonomics makes things comfortable and efficient. Comfort is not like the soft handle, but it is the greatest aspect of the effectiveness of the design. The physical comfort is the feel that a user enjoy during the use of the products and services. If you do not like to touch it, you won’t operate, if you do not function it, then it is ineffective. The usefulness of a thing is the only right evaluation of the worth of its design. The job of any designer is to find innovative ways to boost the usefulness of a product. Making an item instinctive and contented to use will make certain its victory in the marketplace. Bodily comfort at the time of making use of an item raises its usefulness.
The Physical Ergonomics can be abridged in a succession of principles. You will be able to see gladly that you can relate these ideologies at home, at work, or the other place you like. The basics of ergonomics are very flexible and acceptable to everybody to match with the everyday routine.
Right Posture: The posture is the key point to evaluate the work you do. The best posture is the neutral S curve of the back both in standing and sitting posture. Working at a stretch for a long time with your backs in a C curve can strain your back. Keep your neck align. Also the elbows and the wrists should be kept in appropriate posture.
Excessive Force Reduction: Your joints may suffer fatigue and injury from excessive pressure. So, it is important for you to recognize an exact case of excessive power and thinking of elevating over time.
Easily reachable things: Keep everything in easily reachable points to grab them without doing extra stretch. Your arm can move semicircle. So, the things that are frequently needed, should be kept within the semicircle, that is called ‘reach envelop’ . Much of the time, the problems can be corrected by rearranging the area of work area and shifting things closer to your reach envelop. This is not at all a rigid idea to understand; you just need the instant smartness to notice the difficulty and modify the setting of things that you want to reach.
Work at proper height: Whether sitting or standing, do most of your work at about elbow height, sitting or standing. However sometimes, there are heavier works that are best done lower than elbow height or below the elbow height.
Reduction of excessive motion: It is very essential to see the number of motions of your fingers, wrist, arm, back etc. . The arrangement of the machine should help elimination of the motion of the body parts.
Reduction of static load and fatigue: Holding the same load for a long period of time causes tiredness and discomfort. This interferes the flow of work. In the workplace, need to hold tools or parts for sometime long is an instance of static load.
Minimization of Pressure Point: The excessive pressure point must be cushioned. The handles of the tools must be contoured to fit in your hand. If you sit on a chair in your workplace, the vulnerable spots like, behind your knees, the end of your forearms etc. must be rested comfortably. The pressure point of the body must be taken care of very well.
Providing Clearance: Work areas are to be arranged to have enough space for your knees, head, and your feet. You evidently must not bump into things every time, or have to work in twisted pose or posture or reach because of lack of space for your arms and feet.
Requiring little Exercises: According to the kind of job you do, different movements of your body like stretching, bending, shifting etc. can be useful.
The job, equipment and workplace should designed according to the science of Ergonomics to prevent strain injuries that may develop over time and lead to long time disability.
