Software to support the solution generation phase of the engineering design process has been developed in academia for decades. Computational synthesis software enables generation of solutions on both conceptual and embodiment level. This paper focuses on the class of parametric design, such as documented in mechanical engineering handbooks. Examples include machine elements such as bearings, springs, fasteners, transmissions, etc. A parametric synthesis tool automates the engineering design process from functional requirements to quantified solutions, for a single machine element. Since the amount of machine elements is vast and software development time should be low, a generic methodology is helpful to speed up this process. This paper discusses such a methodology to develop synthesis tools for the class of parametric designs. It includes an analysis-oriented approach to formalize the design process’ parameters in terms of embodiment, performance and scenario. Mathematical constraint solving techniques are used to generate candidate solutions. Graphical presentation and exploration of the solution space is done with interactive plots. A standardized layout for the graphical user interface is suggested to allow uniform and intuitive use. A demonstrator is developed using the described methodology and several challenges are discussed for improved constraint solving techniques, more advanced visualization and handling problems with higher complexity. Although small in size, parametric design processes are time consuming due to their reoccurring nature. Developing synthesis tools for these designs will allow engineers to save time and improve design quality.

Abstract This paper presents a model of the engineering design process as sequences of transformations between states of the information models describing the design, the functional requirements on which it is based, and the constraints in which it is defined. The design itself is considered to be described by explicit attributes which are the definitive or descriptive properties which affect the manufacture of the object, and implicit, properties which are judgements, performance-related assessments, or emergent properties. The paper first considers the required characteristics of a design model and reviews the use of transformation in design. It then presents an overall transformation model followed by an overview of the use of Petri nets for modelling the detail of the processes.

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.
