Multi-Material Golf Club Head With Ribbon Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads with lightweight composite materials face challenges in achieving structural rigidity, sound quality, and performance due to the weakness of these materials when subjected to forces in orientations other than perpendicular to their fibers, and traditional weight attachment methods can add undesirable weight or compromise structural integrity.
Innovation Solution
A multi-material golf club head design featuring a metallic frontal portion and a lightweight aft portion with an internal ribbon support member, incorporating a lightweight shell and a secondary wall that separates the internal volume into frontal and rear chambers, and includes weight openings and screw weights attached to threaded receptacles in the metallic frontal portion, enhancing structural rigidity and sound quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If lightweight composite material is used to form the aft body portion, then weight is reduced, but structural rigidity deteriorates
Solution Approach 1:
The patent utilizes a hybrid composite structure combining lightweight composite material (for weight reduction) with metallic material (for structural strength). The aft body portion is formed with lightweight composite material while incorporating a metallic frontal portion and metallic reinforcement elements, creating a multi-material composite structure that achieves both weight reduction and structural rigidity
Solution Approach 2:
The golf club head is divided into distinct functional zones: a lightweight aft body portion for weight reduction and a metallic frontal portion for structural strength. This segmentation allows each portion to be optimized for its specific function while working together as an integrated structure
2Ease of operation
If traditional weight attachment methods are used, then weight distribution is improved, but structural integrity deteriorates
Solution Approach 1:
The patent introduces a metallic reinforcement structure as an intermediary between the lightweight composite material and the weight attachment mechanism. This metallic intermediary provides a strong substrate for weight attachment while the lightweight composite material maintains its weight-reducing function, thus preserving both weight distribution benefits and structural integrity
3Strength
If material thickness is increased to strengthen the lightweight portion, then structural rigidity is improved, but weight increases
Solution Approach 1:
The patent applies different material properties to different locations: lightweight composite material is used in areas where weight reduction is critical, while metallic reinforcement is applied locally in areas requiring structural strength. This localized quality differentiation allows strength enhancement without proportional weight increase

AI summary
A multi-material golf club head having an improved performance is disclosed. More specifically, the present invention relates to a multi-material golf club head having a metallic frontal portion and a lightweight aft portion with an addition of an internal ribbon support member. The lightweight aft portion could be formed of a multi-layered sandwich material with at least one layer having low damping properties. The lightweight aft portion may be formed out of a lightweight crown sub-shell and a lightweight sole sub-shell, both of which combine to receive a weighting system.
