Multi-Component Putter With Perimeter Weighting Without Weight Ports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing putter-type golf club heads with weight distribution devices, such as removable weight ports in the heel and toe regions, increase weight and cost, cause vibrations, and alter the sound of the club head, necessitating a design that achieves balanced putting without these complications.
Innovation Solution
A two-part putter design with an upper portion made of low-density metal and a lower portion made of high-density metal, shifting weight towards the periphery to enhance moment of inertia (MOI) without weight ports or attachments, using materials like aluminum and steel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If weight ports are added to the heel and toe regions to increase MOI, then the moment of inertia increases and ball path straightness improves, but the overall weight of the club head increases beyond ideal putter weight
Solution Approach 1:
The putter head uses different materials with different densities in different regions: high-density material (e.g., steel) is placed in the toe and heel regions to increase MOI, while low-density material (e.g., aluminum) is used in the center region to maintain ideal overall weight. This local differentiation of material properties resolves the contradiction between increasing MOI and controlling total weight.
Solution Approach 2:
The putter head is constructed as a composite structure combining multiple materials with different densities. The face and sole portions use high-density materials for perimeter weighting, while the body portion uses low-density material. This composite approach allows simultaneous achievement of high MOI and ideal weight, eliminating the need for separate weight ports.
2Stability of the object's composition
If weight ports are installed in the heel and toe regions to increase MOI, then perimeter weighting is achieved, but manufacturing cost increases due to required cavities and recesses
Solution Approach 1:
The weight distribution function is merged into the main body structure of the putter head. Instead of adding separate weight ports and cavities, the high-density and low-density materials are integrated directly into the face, body, and sole portions during the manufacturing process. This eliminates the need for additional machining operations and reduces manufacturing complexity while achieving the same MOI enhancement.
3Stability of the object's composition
If weight ports are added to the club head to increase MOI, then ball path stability improves, but vibrations occur during impact and sound quality deteriorates
Solution Approach 1:
The putter head employs local differentiation of material density: high-density materials are positioned at the perimeter (toe and heel) to increase MOI, while low-density materials are placed in the center region to reduce vibrations. This spatial distribution of different material properties simultaneously achieves stable ball path and acceptable sound quality without the harmful effects of weight ports.
