Advisor:

Dr. J. Glancey

Sponsor:

Dr. Limin Kung

Mission:

The purpose of our team is to design and build a means to quickly and reproducibly load a test silo without requiring extensive manpower.

Approach:

We will use the Total Quality Design Process, through the SpreadSheet Design Process on Microsoft Excel.

Pros and Cons based upon metrics and target values

Feeding Mechanism: Screw Force Control: Mechanical Sink Depth: Feed Stopping Switch

We start by installing one stopper into the minisilo.

8.25in

This minisilo is then locked into the sliding carriage.

The cut off switch satisfies the proper sink distance constraint .
