Design Efficiency Analysis Towards Product Improvement for Eco- Friendly Using DFMA Method by Mind Map: Design Efficiency Analysis Towards Product Improvement for Eco-  Friendly Using DFMA Method

1. Design for Manufacture and Assembly

2. Proposes to minimize the costs of production and development time, by designing products using the simplest components

3. Design for Manufacturing (DFM)

4. Design for Assembly (DFA)

5. Its purpose is to reduce the manufacturing cost

6. Is oriented to facilitate the assembly process

7. Design for Sustainability

8. Is to design without harming the environment and without depleting non-renewable resources

9. Design for Environment (DFE)

10. Seeks to create an environmental awareness, which is capable of designing preserving the ecosystems

11. For a comparative study of the effectiveness of design in two products

12. Selection of Product for the Case Study

13. Overall Steps to Compute Design Efficiency

14. Analysis of Existing Products for the Theoretical Minimum Part Count

15. Two brands of dry iron are taken

16. Dry iron A Produced by a reputable company

17. dry iron B Produced by an unknown company

18. The design efficiency analysis was carried out based on two factors, namely 1) consideration of the possibility to eliminate the part or to combine with other parts of the assembly, and 2) consideration of the estimated time taken to grasp, manipulate, and insert the part.

19. To calculate the efficiency of the design, movement, isolation and adjustment were evaluated. by the following questions

20. Does this part move relative to all other parts that are already assembled in the system?

21. Must this part be made of different material than other parts already assembled in the system?

22. Must this part be separated from all other parts already assembled in the system?

23. Results

24. The total assembly time of dry iron A was 204.14s with 6 theoretical minimum part count that leads to the design efficiency of 8.82%. The total assembly time of dry iron A was 174.08s with 6 theoretical minimum part count leading to the design efficiency of 10.34%.

25. The number of total components of the new dry iron was reduced from 20 components to 16 with the application of the DFMA analysis. The total assembly operation time reduced from 174.08s to 132.73s. It obviously shortens the assembly time by about 41.35s or 23.75%.

26. Conclusion
