Preliminary Detailed Design
Table of Contents
Team Vision for Preliminary Detailed Design PhaseAt the beginning of this previous phase for this project, the team initially planned to acquire raw shredded cotton material, develop a bill of materials, run feasibility tests on our competitor’s samples, and develop and record test plans for once the team has working prototypes.
During this phase, the team was able to accomplish most of their goals. The team found a supplier and received raw shredded cotton material, as well as purchasing some of the materials needed for prototyping. The team also developed a series of test plans for each benchmarking value for the insulation, which with both purchased materials and test plans, a BOM was also developed.The team was also able to acquire a lab space to develop preliminary prototypes as well as meet with Randy Dohne from Goodwill International, who described the problems facing every Goodwill store across the nation and how the team can solve some of those problems.
Feasibility: Prototyping, Analysis, Simulation
Main Project Resource: Shredded Cotton
- Middle and right picture above are shred samples received from Fiber Conversion in Broadalbin, NY
- Middle picture in particular is shredded denim, much like the Bonded Logic “Ultratouch” product (benchmark product for thermal insulation)
- After evaluation, middle shred is very similar to Bonded Logic in terms of shred character
- Team decided that middle shred would be a good candidate to use for insulation prototypes
Status of Procurement:
Team is in contact with Brian MacFarland at Fiber Conversion. Fiber Conversion shreds textiles and bales them into 600 lb bales. Brian does not want to cut open a bale just to give our team 50-100 pounds to use for our project. Also, he would have to shut down his production line in order to take shredded cotton from the process before it is baled, which he also does not want to do. Brian says he has a bale which was water damaged on one end which he may be able to take some material out of for us. He also has a customer who may have some laying around that he can get for us. Brian is aware that this is a critical resource for our project, and is working hard to find us some material. We are expecting a call back shortly regarding his progress.
Drawings and SchematicBelow shows a schematic of the form that we will be creating our insulation prototypes with. Below the schematic are the drawings of the form with details of the dimensions.
Bill of Material (BOM)
Above is the Bill of Materials that the team made taking every level of the construction into effect. The price may be lower if we are able to use some of the resources RIT has to offer. This BOM includes all of our test plans that will be described below as well.
