  1. Material Storage and Dispensing Device for the Kitchen Charles E Schaefer, Jr. School of Engineering Department of Mechanical Engineering ME 424 Senior Design Proposal Presentation Thursday, February 12th, 2004 Group 9 Ethan Jayson Cora LaFrance Judy Ng Advisor: Professor Zhenqi Zhu

  2. PRESENTATION OVERVIEW • Project Summary • Fall 2003 Recap & Conclusions • Objectives for 2004 • Disciplines • Approach & Methods • Anticipated Problems • Project Deliverables

  3. PROJECT SUMMARY • Design, Analyze & Test a Concept for a Material Storage & Dispensing Device • Explore Existing Products and Designs • Integrate Features to form Improved Design • Perform Material Selection, DFM, and Cost Analyses • Produce Final Design that Meets Design Specifications

  4. Brainstorming Rough Sketches Patent Search Meeting with Advisor/Sponsor Conceptual Designs Alternative Designs Concept Screening & Scoring Final Concept Selection Engineering Analysis DFM Cost Analysis FALL 2003 SUMMARY State-of-the- Art Review

  5. MAJOR COMPONENTS

  6. PRODUCT ASSEMBLY Container Lid Container Spiral Stand Upright Turning Knob Stand Base Material Exit

  7. MATERIAL SELECTION Container: Polystyrene • Low Cost • High Impact Resistance • FDA Compliant for Use with Food • Good Transparency Stand Base: Cast Aluminum Stand Upright: Stainless Steel

  8. TOTAL PART COST ESTIMATION

  9. FALL 2003 CONCLUSIONS • Determined Criteria for Successful Completion of Design Project • Followed Design Process: • Literature and Product Research • Development of Specifications • Formulation of Conceptual and Alternative Designs • Final Design Selection • Engineering and Cost Analyses

  10. FALL 2003 CONCLUSIONS • The Design Team Delivered an Innovation, Simple & Efficient Solution to Design Problem • Design: Spiral Dispensing Mechanism • Height: 17.3 inches • Storage Capacity: 22 Cups (7.5 lbs. of Flour) • Dispensing Capability: ¼ Cup per Revolution • Material + Assembly Cost: $5 to $6 per unit

  11. FALL 2003 CONCLUSIONS • The Design for the Stand Needs Improvement Based on: • FEA Analysis Results • Aesthetic Appeal • Comments and Feedback • Further Design Considerations are Necessary before Design Finalization

  12. OBJECTIVES FOR 2004 Prototype Testing Meet Specifications Quality of Product Promotion of Product Accuracy User Friendly Manufacturability Working Prototype Final Prototype Website Engineering Day Develop Test Procedures Analyze Results

  13. DISCIPLINES – Fall 2003 • Administrative: • Time Management • Cost Management • Patent Research • Marketing: • Market Research & Analysis • Engineering: • Statics • Dynamics • Materials Properties • DFMA • Industrial Design: • Ergonomics • Visual Appeal

  14. DISCIPLINES - SPRING 2004 • Prototyping • Data Analysis • Mechanics of Materials • Manufacturing • Marketing • Web Development • Time/Cost Management

  15. APPROACH & METHODS Final Report & Presentation Engineering Design Day Poster Website Development Stereolithography of Final Design Apply Necessary Design Changes Computer Aided Stress/Strain Testing Test Mechanism in Model Fabricate Working Model Working Model Material Selection Design Changes

  16. ENGINEERING ANALYSISSTRESS & DISPLACEMENT Application of Load From Flour = 7.5 lbs. Center of Gravity

  17. STRESS ANALYSIS Location of Highest Stress Maximum Von Mises Stress: 49.07 MPa

  18. DISPLACEMENT ANALYSIS Location of Max Displacement

  19. REVISED STAND DESIGN • Container & Spiral Will Remain the Same • Improved Stand Design to Reduce Stresses and Deflections • Material: Polystyrene • Goal of Final Design • Stability • Material Usage • Cost Effectiveness

  20. Hole For Stand NEW STAND IDEA

  21. PROTOTYPE FABRICATION • Spiral • Buy Similar Shape • Auger • Injection Molding Screw • Machine a Screw • Container • Construct From Scratch • Plastic • Metal Sheeting • Modify Tupperware-like Containers

  22. EXPECTED EXPENSES $5365

  23. ANTICIPATED PROBLEMS • Mechanism Does Not Perform to Required Specifications. • Finding Proper Materials for Creating a Working Prototype. • Develop a Cost Effective Method to Produce the Product. • Acquiring Parts in Time for Testing. • Learning How to Develop a Web Site.
