Co-Molded Putter Head With Interlocking Composite MOI Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf putters made from metallic materials often result in heavy or bulky designs without maximizing the Moment of Inertia (MOI), leading to unforgiving performance.
Innovation Solution
A putter head design combining a high-density metal chassis with a low-density thermoplastic composite body, featuring interlocking elements to enhance MOI and reduce weight and volume, while improving sound and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If metallic materials are combined to create a putter head with high MOI, then the moment of inertia increases, but the weight and volume increase making the putter heavy and bulky
Solution Approach 1:
The patent combines a high-density metal chassis (providing MOI) with a low-density thermoplastic composite body (reducing weight), creating a composite putter head that achieves high moment of inertia without excessive weight. The chassis is made from high-density metal while the body is made from low-density thermoplastic composite material, resolving the contradiction between MOI and weight.
2Stability of the object's composition
If metallic materials are combined to create a putter head with high MOI, then the moment of inertia increases, but the putter becomes bulky without maximizing MOI efficiency
Solution Approach 1:
The composite construction allows high-density metal to be concentrated in the chassis where it provides maximum MOI benefit, while the low-density thermoplastic composite fills the body volume, achieving high MOI with reduced overall volume compared to all-metal constructions.
3Stability of the object's composition
If two metallic materials are combined, then the MOI can be increased, but the manufacturing complexity and cost increase
Solution Approach 1:
The putter head is segmented into two distinct components: a high-density metal chassis and a low-density thermoplastic composite body. This segmentation allows each component to be manufactured separately using optimal processes for each material, then assembled together, simplifying the overall manufacturing compared to creating a monolithic two-metal construction.
Solution Approach 2:
The use of thermoplastic composite material instead of a second metal simplifies manufacturing. Thermoplastics can be molded using injection molding or similar processes, which are generally easier and more cost-effective than metalworking operations required for combining two metallic materials.

AI summary
Embodiments of a co-molded putter-type golf club head comprising a high-density chassis made of a first material and a low-density putter-type body made of a second material. The first material can be a high density metal (i.e., steel or tungsten, but not limited to). The second material can be a low density thermoplastic composite (i.e., polyphenylene sulfide (PPS), polyamide (PA), but not limited to). The chassis comprises a flow aperture, and one or more interlocking features. The putter-type body portion encases the entirety of the at least one interlocking feature. Further, the putter-type body encapsulates the chassis such that the body extends through, and completely fills the flow aperture, to interlock the body and chassis, and thus form the club head. Other embodiments may be described and claimed.
