“…The key characteristics of this definition were found to be systemic thinking, framing and the application of first principles [1]. Further support for such a definition was also provided by demonstrating how it fits with other explanations of engineering design expertise in the literature ( [2], [3], [4], [5] and [6]) [7]).…”

To date the majority of research into engineering design expertise has been done within an occidental context. With an increase in multinational design firms engineers are now more likely to work with engineers of different backgrounds. The authors’ experience in countries other than their own suggested that background can affect design engineers’ thinking and working, and the nature of expertise. This prompted a study (via interviews) into design teams with mixed (by nationality) members. This investigation into occidental and Sino backgrounds and engineering design expertise showed that a Sino background encouraged low risk reliable designs and detailed thinking while an occidental background promoted unique ideas, systemic thinking and the use of objective knowledge. However, individual change and improvement is possible.

“…To maximize the chances to find effective solutions, it is important to comprehensively explore the design space without incurring in the psychological limitations typically referred to design fixation (Jansson and Smith, 1991;Purcell and Gero, 1996;Vasconcelos and Crilly, 2016;Viswanathan and Linsey, 2018). To support design and problem-solving processes, a plethora of design methods and tools have been proposed in literature (Altshuller, 1984;Cross, 2000;Eder and Hosnedl, 2008;Fiorineschi et al, 2018;Kim, 2018;Kroll et al, 2001;Pahl et al, 2007;Pugh, 1991;Suh, 1998;Terninko et al, 1998), which can be conveniently exploited for this specific case. More specifically, the methodological approach adopted in this paper has been tailored to the specific application by considering the key points of the German systematic design approach (Beitz et al, 1987;Pahl et al, 2007), which is acknowledged as one of the most diffused among scholars (Tomiyama et al, 2009).…”

Purpose The purpose of this study is to identify an innovative solution for the power transmission gearbox of concrete mixers, according to the specifications provided by the company. Design/methodology/approach A tailored systematic design approach (inspired to the German systematic framework) has been adopted to comprehensively gather the company specifications and perform in-depth design space explorations. Subsequently, an iterative embodiment design approach has been followed to identify the size of the components for the preferred concept, by using acknowledged mechanical design procedures and finite element analysis tools. Findings An innovative cycloidal gearbox has been developed, by merging the kinematics underpinning the classical cycloidal drives and the Wolfrom planetary gearbox. The resulting concept provides high reduction rates with a very high overload capacity. Research limitations/implications The main limitation of the studies is the absence of in-depth evaluations usually performed in the detail design phase. However, this limitation is a direct consequence of the company specifications, which only asked to find a preferred concept and to perform preliminary evaluations. Accordingly, the subsequent design optimization are intended to be performed by the company’s staff. Originality/value The present paper shows an original design approach, opportunely tailored to the design of innovative gearboxes. It can be conveniently adapted and reused by designers involved in similar tasks. Moreover, the designed cycloidal gearbox paves the way for important innovations in the field of concrete mixers, allowing to design more robust and compact devices.

“…The importance of this phase has been widely highlighted in literature. For example, Kroll et al mentioned that the conceptual design "significantly affects the product novelty, performance, robustness, development time, value, and cost" (Kroll et al 2001). Suh comments: "In the conceptual design stage, design decisions have the greatest impact on the project outcomes with respect to functionality, performance, appearance, costs and sustainability" (Farid and Suh 2016).…”

A Framework for Concept and its Testing on Patents

The development of a concept for a system is a key step towards creating the system's architecture. Most previous concept development approaches focus on the procedures for the conceptual design activity ‐ the sequence of activities and tasks. Our work is motivated by the desire to move the activities executed in a Concurrent Design Facility more upstream, in order to include choices and trade‐offs among potential system concepts in a digital environment. Therefore, the objective of this work is to develop a concept framework that can systematically represent the concept's constituents, their definitions and interconnections, such that it can be used in a computational environment. We propose a concept framework that is based on six assertions rooted in design theory, that lead to 33 entries in the framework. In order to test the completeness and utility of this framework, we have mapped eight selected US patents to the framework. Patents are a legally viable means for defending an invention, and therefore the patents must logically contain a description of the concept underlying the invention. For this small N study, we chose eight US patents that represent a broad spectrum of engineering systems and methods. The success of this mapping from patents to the proposed concept framework is a necessary condition to demonstrating the completeness and utility of the framework.
