Modular Design Base on Variety Theory

Variety Design not only support to short down development time, and cut down development cost, but also support to response marketing rapid, is a kind of modern design theory which apply on Mass Customization. In some way, Variety Design is a kind of design that integrates standard design and modular design, and Variety Design object is high cost and universal parts that among platform. The authors discuss the modular design role and the different between integral design, promote the method and the step of modular design, so change the low cost parts design, and give an new product based on the platform. Based on this model, they not only save the cost of develop new product, but also save time, achieve advantage which Mass produce process.     

Application of Fractals in Architectural Shape Design

A computer aided method for architectural shape design was developed based on the L systems algorithm, the shape grammar and the space surface equation theory. Various 3D entities such as building grounds, building walls and building domes with fractal characteristics could be generated in a short time by using the computer program. These generative 3D entities were saved in a component database which could help to accumulate design knowledge through continuous expansion. A building could successfully be formed by the designers through selecting proper building grounds, walls and domes from this database. The effectiveness of the proposed method was approved with a case study.

Building Energy Efficiency Design Procedure Based on Digital Technology

Abstract:Digital design technology is crucial for building energy efficiency design, while the key of building energy efficiency design is to analyze the entire design process, dynamic balance and energy cost. Through the application of digital technology in architectural design during its earlier phases, we can analyze such factors as local climate and terrain, create a "virtual building", simulate its actual condition, and conduct a scientific quantitative analysis of the key problems in architectural design. These actions will optimize the proposed design in a timely manner and achieve energy efficient design under the guidance of scientific analysis. Meanwhile, by exploring energy efficiency design procedure based on digital technology, we can adapt to a higher standard of energy efficient design in our new times.     

An evaluation method of design ability usingmental workload assessment

By analyzing the relationship between design ability and design time, mental workload, and design effect, an evaluation method of design ability is proposed. As far as the factors involved in such method are concerned, mental workload is measured by NASATLX (national aeronautics and space administration task load index) scale, design time is acquired with a special program, and design effect is scored by expert. Then, the time spent on new design tasks based on the evaluated ability level is predicted by using support vector machines, which is then compared with real measured time. The result shows that the predicted time is well accorded with the real time, which indicates that the evaluation method of design ability is valid.     

Engine Design Process Re-engineering with Design Relationship Matrix

Shortening lead time while maintaining product quality requires planning the design process carefully. A simple, flexible process-planning mechanism for engine design, the Design Relationship Matrix, is used to achieve it. The matrix represents functional as well as structureal velationships between major components to assure that design information is reliably transmitted through the design organization. An investigation of an engine's design process was made in an automobile manufacturer. The authors identified areas for improvement, and synthesized mechanisms to achieve those improvements.
