Integrating Sustainability in Engineering Design
Published in Toolseeram Ramjeawon, Introduction to Sustainability for Engineers, 2020
Design is essentially a complex problem-solving process and the engineering problem-solving methodology is used to carry out the engineering design process for new things or to improve things. To move toward a more sustainable practice of engineering, the design process must be modified to enable engineers to tackle sustainability issues in a structured manner. The chapter identifies critical tasks in each design phase deemed necessary to move from the conventional design toward sustainable design. It is crucial to the successful delivery of sustainable development to realize that the problem definition stage is where rigorous consideration of sustainable development issues and in particular life cycle thinking approach will generate the greatest benefits. The use of sustainable procurement criteria is an opportunity for clients/owners to build and operate projects in an environmentally friendly manner. Efforts should be made to be as quantitative as possible when evaluating alternative designs. Indicators and metrics that can be used to measure and quantify environmental sustainability need to be developed to provide a basis for decision-making. Finally, the chapter gives some case studies on the application of the sustainable engineering design process in various engineering disciplines.
Introduction
Published in Arthur T. Johnson, Biology for Engineers, 2019
The engineering design process begins with a concept and continues to completion using various tools of engineering, such as mathematics, physics, engineering sciences, computers, and models. Some have suggested that a book on biology for engineers ought to be chock full of equations, quantitative models, and numbers. That approach has not been taken here because the very beginning of an engineering solution, the art of engineering, is the concept, or the vision of what the solution should do and how it should do it. In order to produce an engineering design involving living things, one must be familiar first with how living things work. Then, and only then, should an engineer investigate the question of “how much?”
Engineering Design
Published in Bahram Nassersharif, Engineering Capstone Design, 2022
Engineering design, sometimes known as the engineering method, is a formal, rigorous, and systematic process to optimize a problem. Problems are often expressed as a desire to solve a situation that has not been solved before or improvements on something that already exists, whether it’s a process, a device, or a concept. Consequently, by the very nature of this statement of problems, they are incomplete and ill-defined. The engineering design process starts with defining and understanding the problem and what is to be achieved.

The engineering design process is an iterative, creative, and complex process in which basic sciences, mathematics, and engineering sciences are applied to convert resources to high-quality solutions (ABET, 2019). The engineering design process includes a significant amount of decision-making for meeting the objectives and constraints during the synthesis, analysis, construction, testing, and evaluation (Dieter & Schmidt, 2009; Lewis et al., 2006). Ullman developed the concept of robust decision-making consisting of the decisions made and the information contained in the decision-making effort, which together is key to managing the design process (Ullman, 2001). He introduced several steps into the decision-making flow, including clarifying the issue, developing criteria, generating alternatives, evaluating alternatives, using standards, and deciding what to do next. The decision-making process contains numerous feasible tradeoff decisions under several design preferences and strategies (Antonsson et al., 2008). Tradeoff decisions consist of dropping one quality, quantity, or property of a design in return for improvements in other aspects. Tradeoff decisions can be made by rating the design of the weakest aspect, cooperatively considering the overall performance of the design, or combining these strategies.

The engineering design process covered the following elements: need finding, problem identification and scoping, concept reduction and selection, evaluation, testing, prototyping, and communication. Through this process, we used co-design to ensure the capstone projects developed in the course took end-users seriously as partners in the development process (following the definition of Sanders and Stappers 2008) as well as involving other local actors in the process. The other important stakeholders included the humanitarian agencies, local community, and donors. However, we extend Sanders and Stappers (2008) definition throughout this paper by centring some end-users (as students) as the engineering designers themselves.
Design-based research to broaden participation in pre-college engineering: research and practice of an interest-based engineering challenges framework
Published in European Journal of Engineering Education, 2019
To understand the role of interest-based engineering challenges in achieving authentic engagement in engineering practices for students, we videotaped the students working on their projects and look for themes of engagement as mediated by the engineering design process and the humanistic framework for engineering. The engineering design process as we presented to the students consisted of identifying a problem, understanding the problem, generating potential solutions, evaluating the best solutions, developing the solution, testing the solution, and communicating their solution following the design process model highlighted in Hynes et al.’s work (2011).
