Material Storage and Dispensing Device for the Kitchen Charles E Schaefer, Jr. School of Engineering Department of Mechanical Engineering ME 424 Senior Design Progress Presentation Thursday, March 25th, 2004 Group 9 Ethan Jayson Cora LaFrance Judy Ng Catherine Oldfield Advisor: Professor Zhenqi Zhu
PRESENTATION OVERVIEW • OBJECTIVES • PRODUCT DESIGN • PROTOTYPING PROGRESS • DESIGN TESTING/ANALYSIS • PRODUCT PACKAGING • OBSTACLES ENCOUNTERED
Prototype Design Testing & Analysis Working Prototype Final Prototype Develop Test Procedures Analyze Results Meet Specifications OBJECTIVES Finalize Design Quality of Product Promotion of Product Accuracy User Friendly Manufacturability Website Engineering Day All Components Material Selection
SPRING 2004 SUMMARY Finalize Design FEA Analysis Prototyping: Stereolithography Prototyping: Machine Shop Prototyping: Purchase from Venders Test Working Prototype Analyze Test Results Rework Model (if necessary) Final Prototype Engineering Design Day Website Final Report/Presentation
DESIGN DETAILS • Modified for Greater Versatility • Free Standing • Wall Mounted • Cabinet Mounted • No Additional Parts Needed for All 3 Designs • Reduced Material = Reduced Cost
IncreasedSupport MOUNTING OPTIONS FREE STANDING DESIGN • Movable on Countertop • Base Provides Sturdy Support for the Unit
Mounts To Wall Screw Holes MOUNTING OPTIONS WALL MOUNTED DESIGN • More Counter Space • Mounts Via Screws in the Stand
CABINET MOUNTED DESIGN Mounting Holes MOUNTING OPTIONS • Mounts to the Underside of a Cabinet • Mounting Holes at the Base of Stand Screw Holes
PROTOTYPING • Necessary Elements • For Testing • For Display • Materials • Part Acquisition Plan • Manufacture • Purchase Ready-Made • Current Progress
Physical Testing Container Screw Knob End Cap Numerical Testing Stand Product Display Cover Cap NECESSARY ELEMENTS
MATERIALS • Container – Stereolithography Resin • Screw – Mild Steel • End Cap – Plastic • Knob – Nickel • Cover – Plastic/Stereolithography Resin • Stand – Plastic/Aluminum • Base – Plastic/Aluminum
PRODUCT TESTING • Numerical Engineering Analyses: • Stress Analysis • Displacement Analysis • Working Prototype Test Plan: • Accuracy of Screw Dispenser • Strength of Components • Functionality/User Friendliness
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
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
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
OBSTACLES • Obstacles Encountered • Stereolithography of Parts • Obtaining Screw with Proper Dimensions • Develop Plan for Multiple Mounting Options • Anticipated Problems • Fabrication of Working Model • Testing
