Improvement Processes

From the existing product, I did an analysis which is to improvise the product. We used Design for Manufacturing and Assembly (DFMA) analysis to lower the production costs per unitshorter the assembly timeincrease the reliability and shorter time to market.




To improvise the product, we removed the battery connector and reduced used of  screws from 40 units to 38 units. This improvement have been done by doing snap fit for certain parts.
