  2. Team Members • Daniel Tobin (ME) • Aaron Sieczkarek (ME) • Amina Purak (ISE) • Brenda Lisitano (ME) • Zheng(Flora) Li (EE) GUIDE: Professor Brownell

  3. Agenda • Needs/Specs • Functional Architecture • Our Concept: Mechanical and Electrical • Final Product • Testing • Cost Worth Analysis • AMPL Program • Major Issues • Objective Evaluations • Future Considerations

  4. Customer Needs

  5. Specifications

  6. Functional Architecture

  7. Our Concept: Electrical Circuit Diagram

  8. Our Concept: Electrical Voltage(V) Time (s) Non-linear input test

  9. Our Concept: Mechanical Motor Housing Electronics Box

  10. Final Product Motor Housing Electronics Box

  11. Testing • All specifications tested • Either passed ideally or marginally • No tests failed • Examples of successes • Waterproof • Dustproof • Impact Test • Voltage Test • Aesthetic Survey

  12. Test Results

  13. Cost Analysis

  14. Cost Analysis

Line Balancing Program #SETS set T; #tasks set N; #stations set PreT{T}; #subset of precedence #PARAMETERS param c; #Cycle time in hours (p=10, s=7.5; c=1.5hrs) param d{j in T}; #task duration param b{j in T, k in N}; #cost of doing task "j" in station "k" #VARIABLES var X {j in T, k in N} binary; #1, if task "j" is assigned to station "k", 0, otherwise #OBJECTIVE FUNCTION minimize Stations: sum{j in T, k in N} b[j,k]*X[j,k]; #CONSTRAINTS subject to TaskAssignment {j in T}: sum{k in N} X[j,k] = 1; subject to CompletionTime {k in N}: sum{j in T} d[j]*X[j,k] <= c; subject to Precedence {j in T, k in N, i in PreT[j]:i>0}: X[j,k] <= sum{f in 1..k}X[i,f];

  16. Line Balancing Results Feasible results will be attained for Cycle Times 9 minutes or greater. Shorter Cycle Times will require a further break down of manufacturing processing times.

  17. Life Cycle Assessment

  18. LCA Graphs – ENERGY & CO2 Summary

  19. Major Issues • Concept Choice in MSD I • Initially ordering parts at a low cost • Material selection

  20. Objective Evaluation • Final product meets customer requirements as a proven, robust, functional prototype. Project is on time and under budget. • Several improvements could be made: • Reduced number of parts • Decreased complexity of design • Increased grip of spring clip design • Aesthetic appeal

  21. Future Considerations • A better phone container could be utilized that is completely waterproof. • Decrease number of tools required to build device as to be easily constructed in Haiti • Utilize a specialized motor • Contact Industrial Design Department to find out if any students wish to work on the project as well. • Systems modeling of the motor output and circuitry with a dynamic model.
