Comparing the Design Cognition of Concept Design Reviews of Industrial and Mechanical Engineering Designers

This paper presents the preliminary results of comparing the design cognition of concept design review conversations of two product design disciplines: industrial design and mechanical engineering design. The comparison is based on a protocol analysis of two concept design review cases using the FBS ontologically-based coding scheme. Inter-disciplinary differences of concept design review were first examined in terms of each review session’s focus of cognitive effort expended on reasoning about design problem or design solution. Both review sessions were largely solution-focused, but the industrial design session is relatively more focused on reasoning about the design problem than the mechanical engineering design session. This matches previous findings from cognitive studies into designing processes. When examining the dynamic design cognition, the overall dynamic patterns of concept design review sessions were mainly consistent with the commonalities found in a variety of designing processes, using the measurement of cumulative occurrences of design issues. However, each individual review session’s cognitive focus on either reasoning about design problem or solution appeared as constant throughout the review conversations. This implies that concept design review sessions are different from designing sessions. Previous studies into designing processes showed that designers became less focused on the design problem and more engaged in the design solution as designing progressed

Computational modelling of the design conversation as a sequence of situated acts

This paper describes the design conversation as a sequence of situated acts. It distinguishes the research questions that require attention for the computation of a more situated design conversation; in terms of design actions and design interpretations. It presents an architecture for 'more situated' systems and describes some examples of implementation. The limitations and complexities of what has been achieved are identified

Interpretation-driven mapping: A framework for conducting search and re-representation in parallel for computational analogy in design

This paper presents a framework for the interactions between the processes of mapping and rerepresentation within analogy making. Analogical reasoning systems for use in design tasks require representations that are open to being reinterpreted. The framework, interpretation-driven mapping, casts the process of constructing an analogical relationship as requiring iterative, parallel interactions between mapping and interpreting. This paper argues that this interpretation-driven approach focuses research on a fundamental problem in analogy making: how do the representations that make new mappings possible emerge during the mapping process? The framework is useful for both describing existing analogy-making models and designing future ones. The paper presents a computational model informed by the framework Idiom, which learns ways to reinterpret the representations of objects as it maps between them. The results of an implementation in the domain of visual analogy are presented to demonstrate its feasibility. Analogies constructed by the system are presented as examples. The interpretation-driven mapping framework is then used to compare representational change in Idiom to that in three previously published systems
