Ergonomics in the application and research of iron 1.the design specification Analysis of the human factor Purpose and significance of topics Industrial product design elements, including design, color design and ergonomic design, in which ergonomics is a very important element. However, many products into the market can not achieve the desired results. The reason is not only the production process, performance, material Science, reliability, and design is more important is the product unsuitable for human characteristics related to the neglect of the human factor We often ignore the applications can see a lot of ergonomic products designed to case. Such as computers, usually the keyboard we use are 104 key keyboard, and its six rows of keys are arranged in horizontal lines, and the reference key bit close. So people have to adapt to it when typing, to tighten the elbows, wrist supination, so that all the fingers meet the keys, but this is the arm of the state in its natural state does not match completely. And in the current conditions on the machine, the operator is often left vacant to operate the arm to move the keyboard and mouse, the elbow does not support. At work, the formation of long arm of the shoulder and neck hanging static fatigue, and makes the operator inconvenience against the chair back on the job. When hanging from the back and arm, the weight to be borne entirely by the spine, the result of fatigue or a sore lower back, or give up the maintenance of lumbar posture while sitting straight Tayao humpback, or put up against the edge of the table caused wrist wrist tunnel syndrome. And so on, making the computer operators work posture, most of the recommended textbook is not typing the correct posture. This paper to study the iron design has many problems, many of our enterprises do not attach importance to iron or do not understand the design, ergonomics, product design in the toothbrush in the functional improvements unilaterally, without considerin
