Design: Assistive Device Design Project

January 25, 2001

Description of Project: Teams of four students will design and construct a system to assist a person with a disability. Each group will have a real client to work with. While the grade received on the project will be influenced by the design decisions made during the project, failure to make a successful device, in itself, will not adversely affect your grade. The overriding philosophy of the project has to be one of enjoyment and self-learning. However, an incomplete project that is not delivered to the client can result in a grade of incomplete until the project is completed to the satisfaction of the instructor.

Project work will be evaluated through a series of memos and reports, listed in the schedule below. Each student on the project team will be expected to write at least one memo. However, the grade will be assigned equally to all students, so you are advised to read and critique each other·s memos/reports before submission. Each student will complete a separate detailed technical drawing of some part of the device to be included in the final report and a postmortem report.

Description of Assignments

Proj #1 – Project Selection Memo: Based on presentations by rehabilitation specialists, you are to write a memo describing the project you want to work on.

Proj #2Problem Statement Memo: Based on a meeting with your client, you are to describe the client's limitations and the particular problems he/she faces. In this memo, modify and elaborate on objectives of the project to reflect the particular design requirements you will use.

Proj #3Generate, Evaluate Alternatives: Using information obtained in class during the brainstorming exercise and library research, you are to write up a description of possible solutions to your design problem, with appropriate sketches and lists of advantages and disadvantages for each. At least three alternatives should be provided. Your preferred solution should be identified, along with any additional information that would be required in order to finalize your selection.

Proj #4Project Schedule: Each group is responsible for preparing a time line for completion of the project. This will incorporate the completed phases of the project, but will concentrate on the work that remains to be done. This document needs to be updated periodically as you progress through the project.

Proj #5 – Detailed Design: Following the procedure outlined in, you are to compare each of your designs and select the one that seems most promising. Next, you are to lay out a procedure for analyzing the design to determine shapes, sizes, and materials needed for and effective solution to your problem. If a mockup is needed, you should specify the purpose of the mockup and what it will teach you.

Proj #6Safety Analysis: In this report, you are to describe the safety aspects of your design and of devices for the handicapped, in general. You are to explain the impact of product liability on design and protection of the public from unsafe devices. You should describe the process by which you will insure that your device is fail-safe for your client.

Proj #7 – Final Report: Your final report will report on your project, including description of the client and device, alternatives considered, cost report, time line, safety test, results, and proposed modifications for manufacture. It will be based on your previous reports and can include them with minor modification to make the document read smoothly. It must include at least one CAD drawing by each team member.

Proj #8 – Oral Presentation: Each group will give an oral presentation, describing their project. The presentation should describe the special problem being solved, your solution, cost, time line, and safety. This will be open to the public. Communications instructor will assign grade.

Proj #9 – Client Report: Each group will write a report which can be submitted to the clients consultant which describes the project solution, the benefit to the client, and important facts about the solution, including cost and potential for generalized use. This report will be the basis for reporting on your project to NSF, which is providing the financial support for these projects.

Proj #10 – Postmortem Report: Each student will write a final memo, describing the success (or failure) of the groups design, the effectiveness of the group, the contributions by each individual, and lessons learned.
