Problem Solving Process

The aim of Computer Aided Innovation (CAI) is to support the engineer’s problem solving process with current design method and knowledge base. TRIZ is developed based on the patents analysis within the cross domain in the world and it is used in innovation design widely. Conflict Matrix, Effect, Standard Solution and Separate Principle are the key TRIZ tools used to resolve the inventive problems. And they can also be used for knowledge representation in the design system. As a Computer Aided Innovation System, Innovation Engine is developed and instructed. The effect of TRIZ methodology and CAI system can be proved with the case analysis of the cavity shape design of the rotor channel in the vertical shaft impact crusher. With limited power of electrical motor, there is a technical conflict in a vertical shaft impact crusher when requirement of improving break ratio of the stone materials. With the recommended principle (Curvature), the conception of a channel with a curvilinear shape can be gotten.

A VLCC (very large crude oil carrier) has approximately 1000 curved longitudinal beams, many of which have three-dimensional complicated curvatures. Due to the shortage of highly skilled workers and the need to keep costs down, production and structural designers have worked to reduce the number of such beams. In order to meet the requirements of production, the authors' company has attempted several design approaches for the longitudinal beam layout to reduce the number of beams that have complicated curvature. Recently, through the application of a computer-aided design system, which has been improved for shipbuilding based on the Calma's system, a new design method for the longitudinal beam layout has been successfully developed. A significant number of beams with a twisted configuration have been eliminated and replaced with beams of simpler, two-dimensional shapes. This paper shows the transition of these design approaches, and the application of the new design to building a VLCC.

The Creation

Abstract This paper describes the computer aided design system Modessa. Modessa is developed to support multi-disciplinary design teams in the conceptual design phase. Modessa is based on the “morphological design method” which decomposes the design problem into a number of so called functions. Then several alternatives are identified for each of these functions. These alternatives are visualized using pictures and arranged by function in a matrix which results in a so called “morphological overview”. Finally the alternatives are evaluated based on the customer requirements. The best alternatives for each function are combined to form the optimum solution for the design problem. Modessa supports multi-disciplinary design teams during the conceptual design process by: - Suggesting known design alternatives for design functions, thus leaving more time for the creation of novel design alternatives. - Offering a “common language” to objectively evaluate the design alternatives. - Simplifying the creation and reuse of the conceptual design documentation. Modessa is general purpose in nature and can be used for a wide variety of design applications. The kernel of Modessa is a design knowledge database that increases continuously as design teams add new functions (problems) and appropriate alternatives (solutions). In this paper the use of Modessa is illustrated by an industrial design example.

The automatic creation of garment parametric computer aided design (PCAD) pattern to special body size is rarely classified and need to be finished with man machine interface at present. This has become a critical and challenging issue to hinder the intelligence process of the garment computer aided design (CAD). In this paper, the basic research aimed at the automatic correction pattern of the special size on the womens jacket CAD system was investigated. The popular special size of women trunk and pattern amendment was selected as research subject, and the relationship between the body characteristics and coat pattern Fig. were set up. The full-scale constraint was developed and the expertise description about womens jacket patterns were finished with the parametric design method based constraint. The mathematic formula and logical definition relation are used to establish relationship with the formed model characteristics of womens jacket patterns. The system then carry and keep the design of womens jacket pattern and the correction logic, and finish the creation and correction of the geometric model to womens jacket pattern. The expertise knowledge of womens jacket pattern correction is applied by the design of method database. The paper performs the basic research and analysis for the rules database creation in the PCAD system, and makes it possible to the research of intelligent womens jacket pattern design system based body size. It will play an active role to transform traditional design concepts and means.
