This paper proposes the use of a design structure matrix/work transformation matrix (DSM/WTM)-based methodology in academic settings to serve engineering educators as a facilitating tool for predetermining the difficulty and feasibility of design engineering projects they assign, given both the time constraints of the academic term and the expected skill level of the respective learners. By using a third-year engineering design project as a case study, engineering students actively participated in this comprehensive use of DSM methodologies. The engineering design process has been thoroughly analyzed to determine convergence characteristics based on the eigenvalues of the system followed by a sensitivity analysis on the originally determined DSM based on data provided by students in terms of task durations and number of iterations for each task. Finally, an investigation of the design process convergence due to unexpected events or random disturbances has been conducted. The obtained predictive model of the design process was compared to the actual dynamics of the project as experienced by the students and the effect of random disturbances at any point in the design process has thereby been evaluated.

Students learning design engineering at times need a good example of procedure for novel design engineering. The systematic heuristic-strategic use of a theory to guide the design process – Engineering Design Science – and the methodical design process followed in this case study is only necessary in limited situations. The full procedure should be learned, such that the student can select appropriate parts for other applications. Creativity is usually characterized by a wide search for solutions, especially those that are innovative. The search can be helped by this systematic and methodical approach. This case example is presented to show application of the recommended method, and the expected scope of the output, with emphasis on the stages of conceptualizing. The case follows a novel design problem of a mechanism to open and close the bow thruster covers for the Caravan Stage Barge.

Early Design Phase

The early evaluation of a proposed function structure for a product and also, the possibility to expose the potential failures related to this provides that the design process can be modeled in its entirety. However, so far there are no existed suitable models for the early phase of design process. This article presents an integrated approach aimed to explore the behaviors of concept designs in the early design phase. The approach is founded on a combination of Petri net, π-numbers, qualitative physics principles and Design Structure Matrix. The final aim is to implement this method on the SysML modeling language to integrate a simulation approach that is initially not standardized in the language. A second interest of the approach is to provide a coherent simulation framework that can be used as a reference to verify the coherency of other simulation models further in the design process.

Scale Design

Abstract Individual engineering design projects face different challenges depending on their scale. Instead of dealing with problems of complex multidisciplinary systems, small scale design must overcome issues of limited resources. The philosophy of agile software development has been highly successful in addressing similar issues in the software engineering realm over the past two decades. Through the design and prototyping of a low-budget desktop stereolithography printer, the application of agile principles to engineering design process is explored. The printer’s design is discussed in detail to provide examples of successes and failures when these agile principles are put into practice. The paper concludes with a discussion of how agile principles could be leveraged in engineering design. The approach taken in this paper is more of a longitudinal study of a single design process over a twelve-month period as opposed to rigorous experiments that engage multiple users in short design scenarios. Nonetheless, this case study demonstrates how the application of agile principles can inform, improve, and complement traditional engineering design processes.

Engineering design process-oriented STEM activities are activities that involve solving a real-world problem with teamwork by using integrative engineering design and engineering applications using scientific and mathematical concepts and 21st century skills. The research aimed to examine the effects of engineering design process-oriented STEM activities, which were developed for sound concept, on the conceptual development of 6th grade students. In the research, comparative case study design was used. The study group consisted of 40 students attending a middle school in Kayseri, Turkey. The teaching was carried out by the activities in science curriculum in the control group, while it was carried out by engineering design process-oriented STEM activities in the experimental group. Each student was individually interviewed using 11 open-ended questions in a verbal format. The mean of Kappa coefficients of the questions was 0.93. As a result of content analysis, 11 categories, including 21 themes and 81 codes, were obtained. When the differences between pre- and post-interviews were examined, it was seen that conceptual understanding levels of the students in experimental group were more positive than the students in control group. This shows that engineering design process-oriented integrated STEM activities have positive effects on students’ conceptual understanding of sound.

Major Factors

AbstractIt is well-known that creativity is crucial for sustaining a product against competition. Many factors have been proposed in the literature as indicators of creativity, among which outcome-characteristics-based factors are considered the most reliable; among these, the creativity of an outcome is often indicated by two major factors:noveltyandusefulness. Only a few studies address as to how creativity assessment methods and their results can be used during the design process. To systematically address the issue of how to influence creativity of design solutions, the following questions have been framed. (1) Which factors should be used as indicators of creativityconsistentlyacross different phases of the engineering design process? (2) How can creativity be assessed in terms of these factors during the engineering design process? In this work, we considernoveltyandusefulnessas the necessary factors forcreativity. It is found, however, that it is not possible todirectlyassess theusefulnessof outcomes during the design process. Therefore,requirement satisfactionis used as a proxy forusefulness. We propose a creativity assessment method that usesnoveltyandrequirement satisfactionas indicators for creativity; the method can be used for assessing not only complete products but also ideas or concepts, as they evolve through the phases of the design process. The application of the method in design is explained using a detailed example from a case study.

Project Data

Requirements play a critical role in the design process. Much of the project time is spent eliciting the requirements. However, it is observed that students primarily only consider requirements while evaluating the concepts. This paper presents a case study conducted with senior mechanical engineering design students in a capstone course to begin to understand requirement evolution throughout a project. Data in the form of weekly requirements was collected from four teams working in parallel on the same industry sponsored project. The paper introduces the concepts of completeness and specificity that could allow the use of requirements as a tool for measuring project health. The findings from the case study reveal that the completeness and specificity of requirements increase from initial week to final week.

The Impact

Abstract Research on empathy has been surging in popularity in the engineering design community since empathy is known to help designers develop a deeper understanding of the users’ needs. Because of this, the design community has been invested in devising and assessing empathic design activities. However, research on empathy has been primarily limited to individuals, meaning we do not know how it impacts team performance, particularly in the concept generation and selection stages of the design process. Specifically, it is unknown how the empathic composition of teams, average (elevation) and standard deviation (diversity) of team members’ empathy, would impact design outcomes in the concept generation and selection stages of the design process. Therefore, the goal of the current study was to investigate the impact of team trait empathy on concept generation and selection in an engineering design student project. This was accomplished through a computational simulation of 13,482 teams of noninteracting brainstorming individuals generated by a statistical bootstrapping technique drawing upon a design repository of 806 ideas generated by first-year engineering students. The main findings from the study indicate that the elevation in team empathy positively impacted simulated teams’ unique idea generation and selection while the diversity in team empathy positively impacted teams’ generation of useful ideas. The results from this study can be used to guide team formation in engineering design.
