DESIGN PROJECT

ASSIGNMENT

Your task is to make improvements to an existing object or device or invent a new object or device to solve a problem. Create a 3D assembly model of the design using Solid Works. Your design should be complex enough to require the use of many of the functions of the software. Simplifications to the model are reasonable, however, a very simple design will receive a minimum grade. Create 2D multi-view sketch for each part and include dimensions. The sketches with dimensions should be sufficiently clear to manufacturers in the machining shop. Present a discussion detailing the need for improvements in the original design of the selected item or the creativity in the new design

See the examples below to help get you on track in thinking of project ideas.

Example 1: Design of end-effector for minimally invasive surgery

The end-effectors of the surgical instrument are critical parts in minimally invasive surgery. The actuation for most of them, such as opening and closing, and bending if applicable, are actuated by a four-bar linkage mechanism with an inner rod or by cables. Your task is to make improvements to an existing end-effector or design a new end-effector using different mechanical configurations.

Example 2: Design of a novel dexterous instrument for minimally invasive surgery

When performing minimally invasive surgery, one of the most limiting factors is access to the surgical site. Due to the fulcrum effect at the tool insertion point, surgeons operate with 4 degrees of freedom (DOF) rather than the 6 DOF required for full mobility in 3D space. For example, suturing is a highly dexterous task that is very difficult under limited mobility. A common example is when a diseased portion of tissue is removed, and the remaining tissue must be reattached together. Your task is to design a device to overcome the limited manipulability.

PROJECT CONTENTS

Each project entry should contain the following items in electronic form as well as hardcopy:

A. Title Page. Information: project title, school name, your name, your section, date completed, and estimated time to complete. Also include one sentence that describes your project idea.

B. Presentation of your design using Solid Works.

1. Full three dimensional assembly model on one page.

2. 2-D representations with dimensions: Top, Front and Right Views. One page for each part.

3. Layout of the design in Solid Works including dimensions and a scale.

C. Design Summary: A one page discussion of the design modification that points out how the design has been developed and explains why. The text should be clearly written and organized as well as free of typographical or editorial errors.

D. Optional information presented such as cross sections and auxiliary views will be looked upon favorably when the projects are reviewed.

PROJECT PRESENTATION

You will also give a 3-5 minutes presentation of your project during class #14. This should include a PowerPoint presentation and any other supporting material or exhibits that may be helpful in illustrating your design. Your presentation should:

A. Define the problem or device that your design is intended to improve

B. Describe your thought process in reaching the chosen design

C. Present the improvements, utilizing tools that you have learned throughout the semester.

The presentation should provide a concise description of your project. Points will be deducted for presentations of less than 3 and more than 5 minutes in length.
