Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a thinned striking face is used to increase ball speed through elastic deformation, then ball speed is improved, but structural strength and stress resistance deteriorate
Solution Approach 1:
The striking face is designed with non-uniform thickness distribution, featuring a thinned perimeter region for speed enhancement and a thickened stress reducing region for strength maintenance. This local differentiation allows simultaneous optimization of ball speed and structural integrity by assigning different thickness characteristics to different functional zones of the striking face.
Solution Approach 2:
The patent introduces a radial thickness variation dimension to the striking face design, transitioning from a uniformly thin face to a multi-zoned thickness profile. This dimensional change in thickness distribution enables the face to achieve both high elasticity for ball speed and sufficient structural strength through strategic thickening at the stress reducing region.
2Reliability
If a thickened perimeter region is added to improve durability and increase characteristic time, then durability is improved, but weight and manufacturing complexity increase
Solution Approach 1:
The striking face is segmented into distinct functional regions with different thickness characteristics: a thinned perimeter region, a thickened stress reducing region, and intermediate transition regions. This segmentation allows targeted durability enhancement only where needed (at the stress reducing region) rather than uniformly thickening the entire perimeter, thereby reducing unnecessary weight and manufacturing complexity while maintaining durability benefits.
Solution Approach 2:
Instead of uniformly thickening the entire perimeter region, the patent applies thickening only partially to the stress reducing region, which is the specific area requiring enhanced durability. This partial action approach provides the necessary durability improvement without the excessive weight and manufacturing complexity that would result from complete perimeter thickening.
3Weight of moving object
If weight is removed from the extremities of the striking face to optimize weight distribution, then weight is reduced, but stress resistance at the perimeter deteriorates
Solution Approach 1:
The striking face employs local quality differentiation by creating a thinned perimeter region for weight reduction and a thickened stress reducing region positioned inward from the perimeter. This local thickening at the stress reducing region provides the necessary stress resistance without requiring the entire perimeter to be thick, enabling weight optimization while maintaining stress resistance through strategic localized reinforcement.
