TECHNOLOGY AND APPLICATION OF PRODUCT EVOLUTIONARY DESIGN BASED ON CONFIGURATION IN MASS CUSTOMIZATION MODE

Product customization has been recognized as an effective means to implement mass cus-tomization （MC）. A new theory and method for MC-oriented evolutionary design of configuration product is presented based on the study of developing law of evolutionary design in integrated envi-ronment, which focuses on the innovation and reuse properties of configuration product. The key technologies for general requirement modeling in quick response to customer requirement, multi-level stepwise configuration optimization driven by customer requirement and evolutionary deduction of product variable structure based on configuration association are thoroughly investigated. The suc-cessful application of the presented method in the development of real-life products demonstrates its utility, flexibility and robusticity.

Study on Design Methodology of Mass Customization Products

Based on introduction characteristics and classific at ion of Mass Customization (MC), the paper expounds foundations and design me thods of MC. The foundations of MC production are standardization, seriation and normality of production, guiding thought of Concurrent Engineering (CE), ap plication of CAD/CAM technology and etc. And design methods of MC products are d esign for product family, modular design, parameterization CAD, variant design, design for manufacturing (DFM) and design by customers. Design for product famil y is a method that first to design a basic form of the product, and then to with draw variant parameters to become a variable product model, makes a family or a series of product design at the same time. Modular design is that based on produ ct function analysis of different function or the same function but different sp ecification within a certain scope, divides and designs out a series of function modular, and through selection and combination of the modular can make up diffe rent products. Parameterization CAD is a CAD method that has function of dimensi on drive. Variant design is a method that under circumstance of keeping principl e constant and construction similar or likeness, properly adjusts part of constr uction and design parameters to adapt design demands. DFM demands the designer t o consider problems that will appear in manufacture in the stage of design, and to avoid them through optimal design. And design by customers is guiding custome rs to design within the scope of production capacity of enterprise and optional items that enterprise has designed to satisfy their requirements of form, functi on and price. Among them modular design, parameterization CAD and variant design are key technology of design methods of MC products. And design by customers is a main characteristic of design of customization product, and an effective sale means also.

Mass Customization Shaping the Design of Interior

Mass customization is the new frontier in business competition for both manufacturing and service industries. Fundamental changes in markets have occurred in the past 20 years. What were once sellers＇ markets have become buyers＇ markets, The demand became unstable and hard to predict. Homogeneous markets became heterogeneous, which meant a necessity to produce specific products for smaller groups of buyers who demand higher-quality goods that more closely match their individual desires. The author believes that social and economic changes will eventually lead to essential modification of home design. Interior items will become more functional and able to keep up with the personal rhyme of life. This research has shown that requirements both to style and function became very specific and individual. The author believes that future furniture will become rather transforming system than a number of furniture pieces.

Mass Customization and Design for High Density Indemnificatory Housing in China

The use of computer in architectural design shouldn’t sacrifice the pursuit of a human-oriented built environment.The technological applications should be legitimated by the objectives and motivations in multiple dimensions,but not abuse its generative power against the social and cultural interests.This article is based upon our synthetic computational design research for high density indemnificatory housing in China(Fig.1),which challenges the conventional standard design for large scale social housing in the Industrial Era,and reflects our exploration for innovative,multi-disciplinary,systematic and synthetic design in the new design paradigm of computation.It also promotes to shift the privilege of cutting-edge design techniques and avant-garde concepts from the“High(end)Architecture”to the ordinary architecture during the unprecedented built-environment development in China.Architectural design should have no discrimination between the Olympic stadiums in the capital and the social housing in the subordinate developed cities,as they both need to be innovative and meaningful.The final design research outputs address sustainable transformation initiated by the residents during the whole life span of the housing.We believe that the human factor(including stakeholders,users,designers and builders)is even more important in architectural design,city planning,urban design,landscape and interior design while technology development is accelerating.Conceptualization,imagination and systemization would become significant pacemakers which perpetuate design innovation.
