Testing rack

  1. 1. Improvement of the L3 Testing Rack<br />By: <br />AakashBalaji<br />SusmitSukthankar<br />
  2. 2. Product Evaluation<br />What in the testing rack can affect the amount of weight stress outputted by this product onto it’s handler?<br />Size?<br />Shape?<br />Amount of Parts?<br />
  3. 3. Product Evaluation<br />Materials used?<br />Method of Carry?<br />Amount Handled at One Time?<br />
  4. 4. Important Constraints<br /><ul><li>While working through our new design there were a few design constraints we needed to keep in mind:
  5. 5. Number of Plugs must be ≥ 99.
  6. 6. Size must be within a fixed area.
  7. 7. Non-magnetic material with the exception of hardware must be used.
  8. 8. Constant distance between units.
  9. 9. Heat and Cold Resistance</li></li></ul><li>Product Improvement<br />Points of Contention:<br />Steel Base: Wobbly & Heavy<br />Material Use: Could it be lighter?<br />Use of Screws and other Parts: Can these be cut down on so only essential parts add to the overall weight?<br />
  10. 10. Research into Possible Design Options<br />How may we manipulate shape to reduce weight?<br /> The manipulation of the shape of the rack may have allowed us to trim weight.<br />Different Shapes Considered:<br /><ul><li>Elliptical Rings
  11. 11. Circular
  12. 12. Square</li></li></ul><li>Research into Possible Design Materials<br />How may we manipulate material to reduce weight?<br /> The manipulation of the material usage of the rack may have allowed us to trim weight.<br />Different Materials Considered:<br /><ul><li>Garolite
  13. 13. Various Magnesium Alloys
  14. 14. Various Aluminum Alloys
  15. 15. Plastic Polymers</li></li></ul><li>The Decision Matrix<br />These criteria were measured on a different scales and each idea was evaluated fully under this criteria.<br />
  16. 16. Our Decision<br />We decided to remove the steel base of the testing rack. It added unnecessary weight.<br />We created a storage unit for the testing racks in which 4 could be carried or stored at a time reducing overall weight.<br />We also replaced many Aluminum and Steel parts with Garolite because of the lower density <br />2.70 g/cm³<br />VS.<br />1.73 g/cm³<br />
  17. 17. Mass Analysis of the Testing Rack (Before)<br />Final <br />Mass:<br />12.427 lbs.<br />
  18. 18. Mass Analysis of the Testing Rack (After)<br />Final <br />Mass:<br />5.456lbs.<br />
  19. 19. Visual Representation of our Design<br />
  20. 20. THE END<br />
