“…Concerning creativity in design, fixation is a risk. Design fixation can occur due to the involvement of expert designers, who can show blind adherence to a set of already known ideas [55]; the designer consideration of the original functional structure of the product (e.g., functional decomposition, and morphology) [56,57]; the use of CAD tools; and related CAD facilitated design [58]. If these factors represent a general limit to design creativity, they only partially affect the DA for two main reasons.…”

Engineering design is a knowledge intensive activity for both new and mature technical systems, such as mechanical transmissions. However, design knowledge is often transferred with conservative and unstructured approaches, although knowledge management would be of the utmost importance for modern industries. In this work, we introduce a design tool, called design archetype, for collecting and managing knowledge in systematic design processes. The design archetype addresses input design requirements for different design concepts, therefore, improving awareness of the design process by interactively modifying the design solution due to different input requirements. Finally, the design archetype updates the parameters of a first embodiment computer-aided design model of the concept. A method for the development of design archetypes is presented and applied to two case studies of mechanical transmission subassemblies. The results demonstrate the effectiveness of a systematic design method based on design archetypes stored in the company database.

“…Firstly, depending on their purpose, the models of design tend to associate analysis to either the problem or the solution space. The prescriptive design models inherit the problem-solving interpretation of ASE, where analysis is a step performed within the problem space and includes understanding, decomposition and formulation of design requirements (Wodehouse and Ion 2010;Fiorineschi et al 2016). Although such instantiation of analysis can also be found in some of the descriptive approaches (e.g.…”

“…Firstly, the literature review revealed that analysis is often conceptualised only as a problem-clarification step in the design process (e.g. Roozenburg and Eekels 1995;Mc Neill et al 1998, Wodehouse andIon 2010;Fiorineschi et al 2016). However, the high proportions of solution analysis design operation reveal that teams spent a considerable portion of conceptual design activity increasing the understanding of design solutions.…”

“…Causes for iterations often are unknown design problems. In order to solve them, an analysis must be performed to find out whether the available information is sufficient to understand them [2]. In adaptive design and reverse engineering, questions about design details are in focus [3].…”

One challenge in adaptive design of technical systems is insufficient understanding of the mechanical system behavior. The actual system behaviour often differs from the system behaviour expected by the designer. This is due, for example, to influences from manufacturing, wear, or errors in the designer’s understanding. For the analysis of the differences between expected and actual system behavior, the system behaviour can be observed. Special analysis techniques are often necessary for system observation. However, the missing methodical support in the system-specific use of analysis techniques is a challenge. In this contribution, a methodical support for the selection and adaptation of analysis techniques for system observation is developed. For this, known errors that occur during system observation are operationalised and provided as requirements for evaluation of analysis techniques. The support is provided as a Selection Matrix, in which the evaluated analysis techniques can be selected and adapted. This is evaluated considering an accompanying application to the non-transparent system wood screw connection. By using the analysis techniques selected with the method, it was possible to identify the actual system behaviour and gain new insights. Here, the Selection Matrix provided support through a structured evaluation of analysis techniques. The Selection Matrix also supported the adaptation of analysis techniques for improved observation of the system behaviour. No general statements on the quality of the support by the Selection Matrix are yet possible. Also, the operationalisation of the errors should be improved to reduce subjective influences. Therefore, these topics should be investigated in further studies.
