Left And Right Hands Balanced Design On Modern Product Design

People's left and right hands is one of the important bodies of mankind, by which people carry on producing, exalt the quality of existence and life.

There are about 10% persons are left-handers in the world. As the absolute minority of the population, the left-hander, when they use the product and tool, will face a lot of difficulties, inconvenience, even danger in the reality the life. The universal product design R&D of left and right hands will provide more humanized of service to people.This paper which thoroughly analysis the history of universal product design R&D of left and right hands and its present existence condition, puts forward the left and right hands well balanced design principle, aiming at left and right hands balanced design product.Left and right hands balanced design is a kind of innovation design principle. This paper analyses the physiology characteristic of the left hand and right hand, investigates to consistently use the left hand crowd's need and feeling for product from humanizing the design and universal design theories, and then sum up a left and right hands physiology characteristic main factor of design with balanced left and right hands, the main factor of safety usage, yielding, comfort, identification or etc. According to the dissimilarity of the product structure, it gives theories to instruct the product design development, which are the principles of applying condition to subdivide, simple operation, standard design, permit of the wrong, the dimension approachability usage etc. It applies methods of the modular design, multi-mode usage and symmetry design etc. to instruct resolving problem of the product application design etc.The principle of left and right hands balanced design, laid foundation for universal product design R&D of left and right hands, raising a product an usage of social performance, did some contribution to structure harmonious society and push a social civilization progress.
