Abstract Solid models are static entities, often defined by boundary representation models as sets of enclosing surfaces. Constructive Solid Geometry and feature-based computer-aided design environments create procedural descriptions of 3D objects in forms of history or CSG trees. These representations are temporally fixed, i.e., they describe the state of an object at a point in time. This paper describes a method to represent and capture temporal evolution of solid models — what we call model process history. We define process history to be all states of a model — the search space of design process. This paper presents a representational formalism we call model process graphs (MPGs). We use MPGs to integrate a model’s description with a model of temporal changes that occur during the design process. We believe that MPG representations can have valuable application for many design and manufacturing problems. The paper describes our preliminary results to use MPGs to (1) create a record of design process; (2) store process-based design rationale; (3) represent in-process shapes for machined artifacts. We anticipate that similar structures will find application in other design and manufacturing problems where important process knowledge is embodied by temporal changes occurring in model evolution.

Transfer of knowledge is a common and ongoing area of investigation in many education studies. The topic is of central importance to the education community because it enables educators to understand how knowledge learned in one context can apply, or transfer, to new contexts. This is particularly important in the context of technological innovation and design education. That is, design often requires the generation of solutions that do not already exist. Generating unique solutions requires the ability to recognize when previous knowledge or learning is appropriate, and then to accurately apply previous learning to novel situations. Furthermore, focusing on transfer of knowledge brings a learner-centered approach to education such that learning experiences are designed to reinforce and to build on students’ prior knowledge. This paper presents results from a study that measured the type of design process knowledge that gets transferred into and out of design-focused courses. The study included approximately 100 students in three different courses: one freshman and two upper-level design courses. Results from this study shed light on the nature of students’ design process knowledge, as novice (freshman) as well as more experienced (junior and senior) student designers. In addition, study results show significant increases in pre- and post-measures of design process knowledge as students advance in the curriculum. Finally, we describe our findings in the context of an emerging framework for instruction and assessment: adaptive expertise. The concept of adaptive expertise is relevant to design education since it presents a model that guides the educational experience to have a balance of gaining technical proficiency with opportunities for applying one’s knowledge in innovative ways.

Design Process Management

According to the state-of-the-art of design process management, a new management method is presented in this paper. Firstly, a design process is divided into three layers: harmony layer, purpose layer and action layer. Secondly, considering the operation features in every design process layer, tasks are divided into four categories, and the relevant models are proposed subsequently. Finally, the framework of a design guide management system is presented, and an example of engine design process is used to illustrate the efficiency of this method. It is approved that the design guide can accumulate design process knowledge and improve design efficiency.
