Golf Club Head Compression Channel for Higher COR Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads face challenges in maximizing energy transfer and reducing energy loss during impact with a golf ball due to deformation of the ball and inefficient energy distribution within the club head.
Innovation Solution
The golf club head incorporates a compression channel across the sole with internal and external ribs, featuring angled and diverging ribs within the channel, and a void on the sole, enhancing energy transfer and reducing deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the golf club head uses a traditional solid structure without channels or ribs, then the structural strength is sufficient, but the energy transfer efficiency is reduced due to ball deformation and energy loss
Solution Approach 1:
The club head body is segmented into multiple regions by incorporating channels and ribs. The channel divides the sole into heel and toe portions, while ribs further segment these regions. This segmentation allows different areas to independently manage stress and energy during impact, reducing overall energy loss while maintaining structural integrity.
Solution Approach 2:
Different regions of the club head are given different structural qualities through the channel and rib design. The heel portion and toe portion have distinct rib configurations (first rib in heel, second rib in toe) that provide localized stress management. This local quality optimization reduces energy loss in specific high-stress areas without unnecessarily complicating the entire structure.
2Productivity
If the golf club head incorporates a compression channel with multiple ribs across the sole, then the energy transfer efficiency is improved, but the manufacturing complexity increases
Solution Approach 1:
The channel and ribs are designed as integrated features of the club head body, merging multiple structural elements into a unified design. The first rib extends from the channel in the heel portion, the second rib extends from the channel in the toe portion, and the third rib connects these elements. This merging approach allows the components to be manufactured as a single piece, reducing assembly complexity while achieving improved energy transfer efficiency.
3Area of stationary object
If the golf club head uses a larger face area, then the area of greatest response (hot zone) can be expanded, but the weight of the club head increases
Solution Approach 1:
The channel creates a porous or hollow structure within the club head body, specifically in the sole region. This porous design reduces the amount of material required in the club head, thereby reducing weight, while still maintaining sufficient structural strength. The void space allows for weight reduction without compromising the face area or overall club head dimensions.
4Weight of moving object
If the golf club head incorporates voids and channels in the body, then the weight is reduced and energy transfer is improved, but the structural strength may be compromised
Solution Approach 1:
The club head employs a composite structural design combining solid and hollow regions. The body includes both solid portions (providing strength) and hollow portions (channels and voids providing weight reduction). This composite approach allows the structure to maintain sufficient strength while reducing weight. The ribs act as reinforcement elements within the hollow structure, further ensuring structural integrity despite the reduced material volume.

AI summary
A ball striking device, such as a golf club head, has a face with a striking surface configured for striking a ball and a channel extending across a portion of the sole. The channel may be recessed from adjacent surfaces of the sole and have a depth of recession from the adjacent surfaces of the sole. A pair of ribs are positioned within the channel. The ribs may diverge away from one another and may have a first rib located in a toe portion of the channel and a second rib located in the heel portion of the channel.
