“…Hannah defined design templates as reusable design process modules that support decision-making at various stages in the design process (1) . Abbott focused on the importance of functional templates and showed that a template tool for functional modeling helps a user develop modeling skills even if he/she does not possess extensive background knowledge (2) (3) . Nonetheless, there are three difficulties involved in template-based design.…”

We focused on developing a management system that provides a design process in which the important attributes of the product can be easily incorporated. We developed a knowledge template to express the product information using five types of knowledge, namely, knowledge about product structure, product entity, product function, product constraint, and product design process. To determine a suitable design process, we first compared the knowledge template of existing products with the product being designed. We calculated the consistency between the two models. From the results of the consistency calculation, we selected and extracted the available knowledge. We created a new design process by using the knowledge extracted from the design template. Finally, we evaluated the process from three perspectives: the ease with which the customer requirements could be reflected, the level of difficulty of the design conflict problem, and the level of difficulty of the design loop problem. Based on the results of this evaluation, designers can select a process to design a new product. We developed a prototype system and used it to design an ocean thermal energy conversion (OTEC) system. The design knowledge for an actual OTEC design was adequately represented by the proposed knowledge template. The most important attribute has a higher value in the design process obtained using the proposed management system process than in the existing system. The proposed management system yields a design process that can easily reflect customer requirements.

This paper describes one experiment to test the utility of component functional templates as a functional modeling instruction aid. Previous research by the authors has shown that problems exist with students describing functional representations of a system or subsystems. Component functional templates were derived as a means of addressing this ongoing problem. The experiment was performed on a section of sophomore level undergraduate students and consisted of both a pre and post-test. During the pre-test, the students were divided into small groups of two or three and given the task of creating a functional model for a small consumer product. The lesson prior to the task was based only on a review of the functional modeling lesson taught in a freshman design course. After the pre-test, another lecture was provided that covered the use of the component functional templates. Next, for the post-test, the students were again asked to create a functional model of the same product. It was hypothesized that the use of the templates would provide better results in the quality and accuracy of the models when compared to the models produced without the use of the templates. The results of the experiment confirmed the hypothesis that the component function templates assist novice design students to create higher quality functional models and offer a foundational basis for further experimentation and evaluation.

An engineering design curriculum that introduces functional modeling methods is believed to enhance the ability to abstract complex systems, assist during the concept generation phase of design, and reduce design fixation. To that end, a variety of techniques for considering function during design have been proposed in the literature, yet there are a lack of validated approaches for teaching students to generate functional models and no reliable method for the assessment of functional models. This paper presents a study investigating students' ability to generate functional models during a homework assignment; the study includes three different treatment conditions: (1) students who receive only a lecture on functional modeling, (2) students who receive a lecture on functional modeling as well as a step-by-step example, and (3) students who receive a lecture, a step-by-step example, and an algorithmic approach with grammar rules. The experiment was conducted in a cornerstone, undergraduate engineering design course, and consequently, was the students' first exposure to functional modeling. To assess student generated functional models across all three conditions, an 18 question functional model scoring rubric was developed based on flow-based functional modeling standards. Use of the rubric to assess the student generated functional models resulted in high inter-rater agreement for total score. Results show that students receiving the step-by-step example perform as well as students receiving the step-by-step example and an algorithmic approach with grammar rules; both groups perform better than the lecture-only group.
