Creative connections: user, designer, context, and tools

The design symposium ‘creative connections discusses the designers’ tools in the conceptual phase. Over the past few decades, many considerations, which hitherto occured before or after conceptualizing have become an integrated part of concept development. Examples are studies of users and contexts, and expressive new materials. Also, design tools are becoming increasingly, almost exclusively, computer-based. But current computer tools lack fluency, directness, and bodily involvement of the traditional paper tools, properties which are essential in the creative activities of conceptualizing, The symposium, and its four attached bazaar papers, deal with new tools that are being developed, and old tools that are evolving, to help designers at coping with this complexity of factors. This paper is part of the 3AD design colloquium creative connections.     

Automatic Virtual Entity Simulation of Conceptual Design Results—Part Ⅰ:Symbolic Scheme Generation and Identification

The development of new products of high quality,low unit cost,and short lead time to market are the key elements required for any enterprise to obtain a competitive advantage.For shorting the lead time to market and improving the creativity and performances of the product,a rule-based conceptual design approach and a methodology to simulate the conceptual design results generated in conceptual design process in automatical virtual entity form are presented in this paper.This part of paper presents a rule-based conceptual design method for generating creative conceptual design schemes of mechanisms based on Yan's kinematic chain regeneration creative design method.The design rules are adopted to describe the design requirements of the functional characteristics,the connection relationships and topological characteristics among mechanisms.Through the graphs-based reasoning process,the conceptual design space is expanded extremely,and the potential creative conceptual design results are then dug out.By refining the design rules,the solution exploration problem is avioded,and the tendentious conceptual design schemes are generated.Since mechanical,electrical and hydraulic subsystems can be transformed into general mechansims,the conceptual design method presented in this paper can also be applied in the conceptual design problem of complex mechatronic systems.And then the method to identify conceptual design schemes is given.

A functional approach to redesign

This paper describes a methodology to assist in the identification of possible conceptual design variants during redesign. The approach is based on functional reasoning and involves: (1) the structural and functional analysis of an existing design; (2) the production of abstract representations of functions and design entities using conceptual graphs; and (3) design interrogation based on a functional tree approach. The research reported in this paper also focuses on the definition and the representation of elementary mechanical functions. Extended Backus-Naur Form (EBNF) notations are used to structure in a computable form, the relevant information (or design knowledge) conceptualised in either the conceptual graphs or the functional trees. EBNF syntax is also used to formulate rules which aid the partial automation of the reasoning process. The EBNF notations can be mapped to any programming language. A diaphragm valve is used as a case study to demonstrate the approach.     

A knowledge-based framework for creative conceptual design of multi-disciplinary systems

Designers often have difficulty in fulfilling creative conceptual designs of multi-disciplinary systems due to the lack of sufficient multi-disciplinary knowledge. Therefore, this paper proposes a knowledge-based framework for the creative conceptual design of multi-disciplinary systems through reusing and synthesizing known principle solutions in various disciplines together. It comprises a formal constraints-based approach for representing the desired functions, a domain-independent approach for modeling functional knowledge of known principle solutions, and a heterogeneous-object-state-search-based approach for synthesizing known principle solutions together for achieving the desired functions. A design case illustrates that the proposed framework can successfully achieve creative conceptual design of multi-disciplinary systems. A prototype system, called the Intelligent Creative Conceptual Design Platform, is implemented based on this framework.     

Using interactive evolutionary computation to generate creative building designs

In this paper we describe how we have exploited Evolutionary Computation (EC) to generate creative building designs. The algorithm has been implemented to create a design tool for architects called Design Inspiration system (DIS). The interactive design inspiration tool is able to generate initial design concepts of architectural plans. Our approach illustrates what we regard as an ideal strategy towards an organic architecture that is inspired from living organisms and not concerned with architectural style. The current capabilities of the system are demonstrated by the example of designing a library building. The paper ends by describing a comprehensive experiment with a total of 28 volunteer architects as a cognitive performance measurement tool, capable of accurately positioning participants’ performance using the design system. This work was presented in part at the 13th International Symposium on Artificial Life and Robotics, Oita, Japan, January 31–February 2, 2008
