Examples

► A proposal for springs that are less likely to tangle.

The tangling of the springs was causing problems in the customer's assembly process. We made proposals for adding center solid turns, changing the number of coils, and changing the free length, etc., within the constraints of the dimensions, and achieved a spring design that was less prone to tangling.

► A proposal for spring that are less likely to pierce.

The antenna of the tip spring was piercing other spring, forming a lump of spring and causing the customer's production line to stop. By reviewing the shape of end turns and the pitch, we were able to improve the situation.
