Golf Club Weight Attachment for Multi-Density CG Tuning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club weight attachment mechanisms face challenges in achieving structural integrity and proper weight distribution due to material compatibility issues and unwieldy weight configurations, which affect the club's performance and aesthetics.
Innovation Solution
The use of multi-density weights with integrated or coupled components, formed from materials with different densities, allows for precise CG manipulation and weight distribution, using methods like additive manufacturing, swedged bonds, and mechanical coupling to secure the weights to the club head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding is used to attach weights to the club head, then structural integrity is improved, but material compatibility problems occur when weight materials are not compatible with club head materials
Solution Approach 1:
The patent introduces an intermediary bonding mechanism that does not rely on direct welding between incompatible materials. The system uses a compatible bonding interface or transition layer that mediates between the weight material and club head material, allowing structural attachment without requiring material compatibility for direct welding.
Solution Approach 2:
The patent changes the bonding parameter from welding (thermal process) to alternative attachment methods such as mechanical interlocking, adhesive bonding, or interference fits. This parameter change allows attachment of various weight materials regardless of their weldability with club head materials.
2Adaptability or versatility
If compatible weight materials are used for bonding, then material compatibility is improved, but the weight configurations become unwieldy or larger
Solution Approach 1:
The patent employs nested weight configurations where high-density weight material is placed inside a shell or housing that integrates with the club head. This nesting approach allows compatible bonding materials to be used while maintaining a compact overall volume, as the weight is contained within the existing structural envelope.
Solution Approach 2:
The patent applies local quality by using high-density materials only in specific regions where weight is needed, rather than using large volumes of lower-density materials. This allows for compact weight configurations that achieve the required mass without increasing overall size.
3Manufacturing precision
If high-density weight materials are used, then weight distribution control is improved, but bonding compatibility with the club head deteriorates
Solution Approach 1:
The patent segments the weight system into separate components: a high-density weight core for precise mass control, and a separate bonding interface or housing for attachment to the club head. This segmentation allows optimization of each component independently - the core for density and the interface for bonding compatibility.
