“Toying” to Learn for 21st Century Product Development Environments: Computer-Aided Design, Collaboration, and Rapid Prototyping

Abstract

A successful hands-on learning environment has been developed for a computer-aided design and prototyping class (ME444). The goals for this course are a) to help students learn multi- dimensional aspects of advanced product design and b) to allow them to practice in a collaborative environment while prototyping a working toy. The learning environment combines (1) hands-on use of the Intranet for computer-based learning, (2) a team-based project to prototype a real product, (3) virtual design and assembly of the student-created toy using CAD, (4) realistic budgeting and design constraints, and (5) advanced prototyping techniques. The first phase of the course focuses on learning advanced CAD tools using web-based learning software. Both the instructor and teaching assistants help students in the laboratory. The students design a toy conceptually as they become familiar with CAD tools. In the second phase, each group designs a toy using a budget to buy standard parts such as motors and controllers. The complete design, assembly, and simulation of functionality of the toy are performed using advanced CAD tools. The constraints of the rapid prototyping process are included in the design criteria. In the last phase, a working prototype of the toy is created using a laser-based rapid prototyping process for the end-of-semester product fair. The course creates a sense of ownership of the project by allowing students to design their own project.

Introduction

An observation made in 1965 by Gordon Moore, co-founder of Intel, was that the number of transistors per square inch on integrated circuits had doubled every year since the integrated circuit was invented. Data density has doubled approximately every 18 months, which is the current definition of Moore's Law. Most experts, including Moore himself, expect Moore's Law to hold for at least another two decades. The improvement of computation power has spawned many innovations in software in diverse areas. Early Computer-Aided Design (CAD) was used for time-consuming computations in the shipbuilding and aerospace industry. However, it was cumbersome to use and accessible to only a few large corporations. In time, computers became cheaper, and interactive software was enabled through the commercialization of the mouse and
