Promoting excellence in sustainable manufacturing has emerged as a strategic mission in academia and industry. In particular, universities must prepare the next generation of engineers to contribute to the task of sustaining and improving manufacturing by providing appropriate types of sustainability education and training. However, engineering curricula are challenged in delivering educational training for assessing technical solutions from the three domains that define sustainability: economic, environmental, and social. In the research presented here, an educational framework is developed with an aim to improve student understanding of sustainable product design (PD) and manufacturing. The framework is founded on the analyze, design, develop, implement, and evaluate (ADDIE) model for instructional design. The developed framework is demonstrated using an example of a sustainable PD activity. This instructional design case study illustrates how engineering students would be able to investigate the impacts of raw materials, unit manufacturing processes, manufacturing locations, and design changes on product sustainability performance by integrating PD information and manufacturing analysis methods during the PD phase.

Efforts to reduce product environmental impacts such as energy consumption and carbon footprint have received attention for many years, often driven by consumer pressure on companies to produce more environmentally friendly products. As the next generation of engineers who will take responsibility for advancing the sustainability of products, processes, and systems, engineering students need to become more familiar with the concepts of sustainable product design and manufacturing. Yet, educators are disadvantaged in training these students, and tools are deficient in assisting product sustainability assessments for manufacturing decision making by other non-experts. A manufacturing analysis module is introduced, which was developed under collaborative research titled, Constructionism in Learning: Sustainable Life Cycle Engineering (CooL:SLiCE). This CooL:SLiCE manufacturing analysis module provides an opportunity for non-expert students and engineers to investigate the impacts of product design changes on manufacturing processes and supply chain network configurations, e.g., selection of upstream processes, transportation routes, and transportation modes, from environmental responsibility perspective. One popular consumer product, a multicopter, is selected to demonstrate the module. The production of three hexacopter components are evaluated: the upper shell, lower shell, and propeller. The manufacturing analysis module enables non-experts to gain a better understanding of sustainable product design and manufacturing.

Abstract Human beings are physically and cognitively variable, leading to a wide array of potential system use cases. To design safe and effective systems for highly heterogeneous populations, engineers must cater to this variability to minimize the chance of error and system failure. This can be a challenge because of the increasing costs associated with providing additional product variety. Most guidance for navigating these trade-offs is intended for late-stage design, when significant resources have been expended, thus risking expensive redesign or exclusion of users when new human concerns become apparent. Despite the critical need to evaluate accommodation-cost trade-offs in early stages of design, there is currently a lack of structured guidance. In this work, an approach to function modeling is proposed that allows the simultaneous consideration of human and machine functionality. This modeling approach facilitates the allocation of system functions to humans and machines to be used as an accessible baseline for concept development. Further, a multi-objective optimization model was developed to allocate functions with metrics for accommodation and cost. The model was demonstrated on a design case study. 16 senior mechanical engineering students were recruited and tasked with performing the allocation task manually. The results were compared to the output of the optimization model. Results indicated that participants were unable to produce concepts with the same accommodation-cost efficiency as the optimization model. Further, the optimization model successfully produced a wide range of potential product concepts, demonstrating its utility as a decision-aid.

This article addresses the issue of educating engineering students with the knowledge and skills of Computer-Aided Design and Manufacturing (CAD/CAM). In particular, three carefully designed tutorials—cutting tool offsetting, tool-path generation for freeform surfaces, and the integration of advanced machine tools (e.g., hexapod-based machine tools) with solid modeling—are described. The tutorials help students gain an in-depth understanding of how the CAD/CAM-relevant hardware devices and software packages work in real-life settings. At the same time, the tutorials help students achieve the following educational outcomes: (1) an ability to apply the knowledge of mathematics, science, and engineering; (2) an ability to design a system, component, or process to meet the desired needs, (3) an ability to identify, formulate, and solve engineering problems; and (4) an ability to use the techniques, skills, and modern engineering tools that are necessary for engineering practice. The tutorials can be modified for incorporating other contemporary issues (e.g., additive manufacturing, reverse engineering, and sustainable manufacturing), which can be delved into as a natural extension of this study.

One of the primary issues with many product design and development processes today is having a good balance between the elements of form and function. While all products must be able to perform their intended functions, considerations of aesthetic features are also necessary for them to be accepted as a good quality design. However, most available design and development processes of consumer products have been more focused on achieving the functional aspects and have tended to treat the aesthetic aspects as less crucial features. This approach has led to many failed functional products in the market, as their physical design lacks appealing factors to targeted users. To improve the situation, a new product design and development framework is proposed in this study to better facilitate designers or engineers in creating an all-rounded quality product design. This new method is developed based on the findings from a survey conducted among engineering students, who are future product design engineers, in order to identify and also resolve issues with the current methods that they typically apply for their design tasks. All in all, the new proposed method is fundamentally tailored to offer a structured guide for developing beautiful and useful products based on a semantic design approach.

In the context of a circular economy, one can observe that (i) recycling chains are not adapted enough to the end-of-life products they have to process and that (ii) products are not sufficiently well designed either to integrate at best their target recycling chain. Therefore, a synergy between product designers and recycling-chains stakeholders is lacking, mainly due to their weak communication and the time-lag between the product design phase and its end-of-life treatment. Many Design for Recycling approaches coexist in the literature. However, to fully develop a circular economy, Design from Recycling also has to be taken into account. Thus Re-Cycling, a complete circular design approach, is proposed. First, a design for recycling methodology linking recyclability assessment to product design guidelines is proposed. Then, a design from recycling methodology is developed to assess the convenience of using secondary raw materials in the design phase. The recyclability of a smartphone and the convenience of using recycled materials in a new cycle are both analyzed to demonstrate our proposal. The Fairphone 2® and its treatment by the WEEE French takeback scheme are used as a case study.

The Finite Element Analysis (FEA) is becoming increasingly popular among design engineers using it as one of many product design tools. Safe and cost efficient use of FEA as a product design tool requires training, different from that presently found in undergraduate curriculum of mechanical engineering students. The specific requirements of design engineers for training in the field of FEA have been addressed by the author in a number of professional development courses in FEA, catering specifically to the needs of design engineers. This paper discuses tools and methods used in the development and delivery of these courses and their applicability to the undergraduate courses taught in Canadian Engineering schools.

This chapter discusses two games that were designed to target learning as well as implications for the design of future games intended for this purpose. It illustrates how the ADDIE model of instructional design can be leveraged to produce digital game spaces as well as the limitations that designers face based on the goals of the project, the chosen technology, and the audience chosen for the digital intervention. The goal of this chapter is to use real-world examples of learning game design processes in order to prepare instructional designers for the complexity of using game and instructional design principles as a means of improving student motivation, learning, and other psychological factors that prepare them for engaging meaningfully in the educational experience.
