In recent years, there has been a significant push towards “Design for X” (DFX) in modern engineering design practice. One such category that has received a large amount of attention is design for manufacturing. When conducting design for manufacturing, a common tool to assist in the design process is design for a series of design for manufacturing guidelines. While the use of these guidelines, as well as other DFX guidelines, has been shown to be effective, little research has been done with the intent to standardize the guidelines or make them more readily available. In this paper, the authors propose a Design for Manufacturing database tool to assist in the instruction of design for manufacturing guidelines. The development of the database model is discussed, as well as the interface that is used to interact with the database. The tool is then evaluated and conclusions are made with regards to the effectiveness of the database and any future work to increase the functionality. One major addition that is discussed is the adaptation of the database for use in industry, and not just in education, to assist in the engineering design process.

Abstract Today, engineering designs are tackling projects of increasing complexity and cost. The constraints are getting more complex, there are new materials and processes to exploit and stricter regulations and legal requirements to satisfy. Making products more quickly and efficiently is even more important in these times of increasing economic competition. Over recent years, use of computer tools in the design-analysis-manufacture stages has led to decreased lead times and reduced product costs. In particular, in the engineering design process, it has become clear that more extensive computer based support tools would result in greater gains. These include tools that help the designer maintain consistency in the design representation, help in documentation of information such as design intent, perform knowledge based manufacturing analysis and help in the generation of intelligent manufacturing plans. Progress has been made in the representation of design entities, as can be seen, for example, in geometric modeling. However, as this article point out, the techniques and methodologies underlying current Computer-Aided Design (CAD) systems are an insufficient basis for realizing automation of the engineering design process. This article proposes that an integration of Artificial Intelligence (AI) techniques with geometric modeling systems can better meet the requirements of Computer-Aided Engineering (CAE) design practice.

Purpose The purpose of this study is to examine a week-long science, technology, engineering and mathematics (STEM) project-based learning (PBL) activity that integrates a new educational technology and the engineering design process to teach middle and high school students the concepts involved in rotational physics. The technology and teaching method described in this paper can be applied to a wide variety of STEM content areas. Design/methodology/approach As an educational technology, the dynamic and interactive mathematical expressions (DIME) map system automatically generates an interactive, connected concept map of mathematically based concepts extracted from a portable document format textbook chapter. Over five days, students used DIME maps to engage in meaningful self-guided learning within the engineering design process and STEM PBL. Findings Using DIME maps within a STEM PBL activity, students explored the physics behind spinning objects, proposed multiple creative designs and built a variety of spinners to meet specified criteria and constraints. Practical implications STEM teachers can use DIME maps and STEM PBL to support their students in making connections between what they learn in the classroom and real-world scenarios. Social implications For any classroom with computers, tablets or phones and an internet connection, DIME maps are an accessible educational technology that provides an alternative representation of knowledge for learners who are underserved by traditional methods of instruction. Originality/value For STEM teachers and education researchers, the activity described in this paper uses advances in technology (DIME maps and slow-motion video capture on cell phones) and pedagogy (STEM PBL and the engineering design process) to enable students to engage in meaningful learning.

Design Ideas

Information is transferred through a process consisting of an information source, a transmitter, a channel, a receiver and its destination. Unfortunately, during different stages of the engineering design process, there is a risk of a design idea or solution being incorrectly interpreted due to the nonlinearity of engineering design. I.e., there are many ways to communicate a single design idea or solution. This paper provides a comprehensive review and categorization of the possible sources of information loss at different stages of the engineering design process. Next, the authors present an approach that seeks to minimize information loss during certain stages of the engineering design process. The paper i) explores design process and dissemination methods in engineering design; ii) reviews prior work pertaining to these stages of the engineering design process and iii) proposes an information entropy metric that designers can utilize in order to quantify information loss at different stages of the engineering design process. Knowledge gained from this work will aid designers in selecting a suitable dissemination solution needed to effectively achieve a design solution.
