spring motion (in the future)
new Spring optimize the physic stroke force in industry line. many level of accelerating increasing rate. patent pending.
Make new springs. Segment 1: Auto. provide comfortness at the same time maximize load ability. new spring rate increase during compression. it increases in many levels to choose.Segment 2: Industry line use, to optimize the industry processing. optimize the physical force by apply a new simple dull metal spring, without using complecated computer controlled adjustment.
