  5. PRODUCT DESIGN

  6. MAJOR COMPONENTS

  7. DESIGN DETAILS • Modified for Greater Versatility • Free Standing • Wall Mounted • Cabinet Mounted • No Additional Parts Needed for All 3 Designs • Reduced Material = Reduced Cost

  8. IncreasedSupport MOUNTING OPTIONS FREE STANDING DESIGN • Movable on Countertop • Base Provides Sturdy Support for the Unit

  9. Mounts To Wall Screw Holes MOUNTING OPTIONS WALL MOUNTED DESIGN • More Counter Space • Mounts Via Screws in the Stand

  10. CABINET MOUNTED DESIGN Mounting Holes MOUNTING OPTIONS • Mounts to the Underside of a Cabinet • Mounting Holes at the Base of Stand Screw Holes

  11. PROTOTYPING • Necessary Elements • For Testing • For Display • Materials • Part Acquisition Plan • Manufacture • Purchase Ready-Made • Current Progress

  12. Physical Testing Container Screw Knob End Cap Numerical Testing Stand Product Display Cover Cap NECESSARY ELEMENTS

  13. MATERIALS • Container – Stereolithography Resin • Screw – Mild Steel • End Cap – Plastic • Knob – Nickel • Cover – Plastic/Stereolithography Resin • Stand – Plastic/Aluminum • Base – Plastic/Aluminum

  14. PART ACQUISITION & PROGRESS

  15. PRODUCT TESTING • Numerical Engineering Analyses: • Stress Analysis • Displacement Analysis • Working Prototype Test Plan: • Accuracy of Screw Dispenser • Strength of Components • Functionality/User Friendliness

  16. CONTAINER - STRESS ANALYSIS

  17. CONTAINER - DISPLACEMENT ANALYSIS

  18. WALL MOUNTED - STRESS ANALYSIS

  19. WALL MOUNTED - DISPLACEMENT ANALYSIS

  20. UNDER CABINET - STRESS ANALYSIS

  21. UNDER CABINET - DISPLACEMENT ANALYSIS

  22. TEST RESULTS • Container • Max Displacement: 0.0467 inches • Max Stress: 6976.31 psi • Factor of Safety: 2.9 • Stand WALL MOUNTED • Max Displacement: 0.0000203 inches • Max Stress: 192.26 psi • Factor of Safety: 100 • UNDER CABINET • Max Displacement: 0.0000218 inches • Max Stress: 192.6 psi • Factor of Safety: 100

  23. CURRENT PROGRESS Final Report & Presentation Group 9 Engineering Design Day Poster Website Development Apply Necessary Design Changes Test Functionality of Prototype Fabricate Working Model Computer Aided Stress/Strain Testing Acquire Material/Components for Prototype Working Model Material Selection Design Changes

  24. PACKAGING OPTIONS • Visit to Grocery Store to Survey “Typical” Package Sizes of Dry Ingredients • Recommendation is to Produce Four Sizes: • Large (22-Cup Capacity): Flour, Sugar, etc. • Medium (10-Cup Capacity): Confectioner’s Sugar, Baking Soda, etc. • Small (2-Cup Capacity): Baking Powder, Yeast, etc. • Extra Small (1/2-Cup Capacity): Spices, Seasoning

  25. OBSTACLES • Obstacles Encountered • Stereolithography of Parts • Obtaining Screw with Proper Dimensions • Develop Plan for Multiple Mounting Options • Anticipated Problems • Fabrication of Working Model • Testing

  26. THANK YOU!
