Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads with thinned faces and thickened perimeter regions do not optimize weight distribution and stress reduction effectively, leading to localized benefits and potential manufacturing challenges.
Innovation Solution
A golf club head design featuring a thickened central region, a central transition region, a thinned intermediate region, a thickened stress reducing region, and a thinned perimeter region, with the thickened stress reducing region forming a ring that protrudes rearward from the internal surface, optimizing weight distribution and stress reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the striking face is thinned out to allow elastic deformation and increase ball speed, then ball speed is improved, but the striking face becomes more susceptible to stress and potential failure
Solution Approach 1:
The striking face is designed with non-uniform thickness distribution, featuring a thinned perimeter region for flexibility and ball speed enhancement, while maintaining a thickened stress reducing region with ring protrusions for strength and stress management. This local quality variation allows different regions to serve different functions simultaneously.
Solution Approach 2:
The striking face is segmented into distinct functional zones: a thinned perimeter region for elastic deformation and ball speed, and a thickened stress reducing region with ring protrusions for structural support. This segmentation allows independent optimization of each region's properties.
2Reliability
If a thickened perimeter region is added to improve durability and increase characteristic time, then durability is improved, but unnecessary weight is added to the extremities
Solution Approach 1:
Instead of uniformly thickening the entire perimeter region, the invention applies localized thickening only in specific areas where stress reduction is most needed, as indicated by the ring protrusions. This localized approach provides durability enhancement while minimizing unnecessary weight addition.
Solution Approach 2:
The thickened stress reducing region with ring protrusions provides more than sufficient stress reduction in critical areas, allowing the extremities to remain thin and lightweight. This partial action approach focuses material placement only where needed for durability.
3Speed
If weight is removed from the extremities of the striking face, then ball speed is improved through increased elastic deformation, but stress resistance may be compromised
Solution Approach 1:
The striking face features a thinned perimeter region for enhanced elastic deformation and ball speed, while a separate thickened stress reducing region with ring protrusions provides localized stress resistance. This spatial separation of functions allows both objectives to be achieved simultaneously.
4Speed
If the striking face thickness is varied to improve performance, then ball speed and characteristic time are improved, but manufacturing complexity increases
Solution Approach 1:
The variable thickness design is implemented through localized modifications (ring protrusions in the stress reducing region) rather than complex overall geometry changes. This approach achieves performance benefits while maintaining relative manufacturing simplicity through focused local adjustments.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves improved performance by reducing unnecessary mass while enhancing structural rigidity and stress resistance, allowing for a thinner face insert and improved ball speed without adding excessive weight.
Implementation Method 1
a thickened stress reducing region, extending outward radially from the thinned intermediate region, having a fourth thickness; and a thinned perimeter region, extending outward radially from thickened stress reducing region, having a fifth thickness, wherein the thickened stress reducing region forms a ring protruding rearward from the internal rear surface of the striking face portion
Implementation Method 2
allowing the striking face to elastically deform when impacting a golf ball, thus increasing the speed of a golf ball once it leaves the striking face of the golf club head
