The Approach Of Work Chair Design That Based On Principle Of Human Factors Engineering

Human Factors Engineering, which is a emerging edge subject, originated from Europe and developed in USA with a history of more than 60 years. Human Factors Engineering is the subject that studies human being's health,safety,comfort and work efficiency in life or work. The core value is unification and harmony of man, machine and environment. In 1968, the IEA held the first international symposium on ergonomic in Switzerland. From that time on, it's raised high tide of chair design all over the world as far as now.Based on the principle of man-machine and environment, and harmony and unification, Human's physiology, psychology and esthetic factors are the main lines, this article looks into affects human body dimension, national standard, human physiology and human cognitive psychology, work motivations, user experience and esthetic factors of work chair design. The article expatiates the man-machine work chair and its evaluation.Human-machine interface design is also discussed here. Taking example of classical human-machine ergonomic chair, this article discussed that human factor is the basic factor of human-machine engineering design. Human-machine connection must meet the need and interest of human.Human factor is transcendental and instinctive, which may be false and inconsequent, so human-machine engineering design shouldn't be adapted blindly and passively, it should focus on human's demand and interest. The design should display the essential initative and take a positive direction of human development. Besides, design of Human-machine connection isn't a matter that who can dominate who must obey to. It's a engineering system that whole achieve optimization as its goal. So human-machine engineering design should coordinate the relation between human and machine, exerts its advantage and role of the both. including the influence, complementarity, emendation between. It should establish the best Human -machine connection, that composed of evaluation system of factors, which including security, comfort, health, capability, benefit and so on. Work chair design is a system project, in nature, it's design for sit, sequentially it's service for work better. In design, we should consider the matching connection of human and machine and its surroundings synthetically. User, work chair and surroundings should be harmonious and uniform. The evaluation of human-machine system of work chair is guaranteed that it wouldn't deviate the tract of human factors engineering. Human-machine engineering design is a incessant enrichment, advancement and breakthrough process. The ideology and method obey of Human-Machine Engineering is developing and advancing day by day, It may bring more novelty and advanced mode of human-machine connection in future. Therefore we need a open horizon to go on explore, innovate and absorb new knowledge to serve better the design of work chair and other products.
