Theories And Methods Of Industrial Product Form's Ergonomics Design

Form design is an important part of computer-aided industrial design. Theproduct form is not only the carrier of product' function, but also is the key factor ofproduct's ergonomics capability. In the study of products form design, analyzing theergonomics capability influenced by form based on products information space wasan efficient strategy for computer-aided form design. This paper carried on research totheory, method and software of product's form design.1. Framework of form ergonomics design's information spaceProducts form was divided into two types: ergonomics form and functional formby analyzing the human-computer interaction of products form design. The interiorprocess and exterior process of product form design based on data information wasstudied, and their structure and character were analyzed. Arming at the form designdeal with ergonomics capability, the method of form design combined withergonomics capability was proposed. The information space of form ergonomicsdesign was constructed after investigating its framework. The information space wasused to do the particular layout for products form ergonomics design.2. Conceptual methods of product form's ergonomics designThe method of product form's ergonomics design driven by information wasstudied. After analyzing the process and goal of human-computer interaction, theergonomic capabilities of product were presented. Picking up the factors deal withproduct form's ergonomics capabilities, the function of mobile phone form'sergonomics design was built. According to the process and capability evaluation ofmobile phone's human-computer interaction, body figure and gesture parameter, twokey actions during using mobile phone were studied: grasp and press. The algorithmof form ergonomics design was proposed which was based on the genetic algorithms.This algorithm put the products form ergonomics into several optimizing problems.The conflict between design objectives and restrictions of mobile phone was resolved.3. Evaluating index of product form' ergonomics designBasing on Kansei Engineering, product form capability was divided intoergonomics gene and form gene and the index gene of form evaluating wasintroduced. Form essential elements used to evaluate products form were built afteranalyzing the effect of products form upon people's consuming action. After selecting the mobile phonesamples and analyzing their form factors, the mobile phone's formstatic factors and dynamic factors were described. According to the factors describingtable, the code of mobile phone's form factors was constructed.4. Evaluating models of product form' ergonomics designAn application case of mobile phone was studied and the evaluating result ofmobile phone sample was obtained by making questionnaire. Two evaluation modelsof products form were built and compared: linearity evaluation model based on theoryof quantification and non-linearity evaluation model based on GA-PSO programmingalgorithm. Comparing the models, the non-linearity evaluation model is closer tomarket condition.5. Products form design software based on SolidworksSolutions to Products form design based on Solidworks are proposed. Based onthe theories and methods of product form ergonomics design, and gave attention toboth integer form and detail parts of products, a prototype of products form designwas developed. With the support of the project, products form design was applied andtested by enterprises. The result demonstrated that the theories and methods ofproduct form ergonomics design is a valid design method for computer-aidedindustrial design.
