Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club head technologies face challenges in enhancing playability characteristics while managing weight and mass distribution, particularly at locations of high stress and limited thickness, while maintaining structural resilience.
Innovation Solution
A golf club face plate with an internal cell lattice structure, comprising an inner skin, outer skin, and a midsection with a cell lattice encapsulated between them, formed through a high-pressure and high-heat diffusion bonding process, allowing for weight reduction without compromising strength or durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If weight is reduced in golf club head, then playability characteristics are improved, but structural resilience deteriorates
Solution Approach 1:
The patent employs a cellular lattice structure within the club head body that creates a porous-like internal architecture. This structure reduces overall weight while maintaining structural integrity through the distributed cell walls that provide load-bearing pathways throughout the material volume.
Solution Approach 2:
The patent integrates multiple materials with different properties - a metallic base material combined with cellular structure - to achieve optimal balance between weight reduction and structural resilience. The composite approach allows zones of varying density and strength throughout the club head.
2Weight of moving object
If mass is redistributed in golf club head, then playability characteristics are enhanced, but structural integrity at high stress locations deteriorates
Solution Approach 1:
The cellular lattice structure is designed with varying cell sizes, densities, and orientations in different regions of the club head. High-stress areas feature denser, more robust cell structures that maintain strength, while lower-stress areas have reduced material content for weight savings.
Solution Approach 2:
The patent transitions from traditional two-dimensional face plates to a three-dimensional cellular lattice architecture. This dimensional change allows mass to be distributed throughout the volume rather than concentrated in flat surfaces, enabling better stress management while maintaining structural integrity.
3Weight of moving object
If cell lattice structure is used, then weight savings of 8% to 25% are achieved, but manufacturing complexity increases
Solution Approach 1:
The manufacturing process utilizes controlled variations in temperature, pressure, and material flow parameters during forming to create the complex cellular lattice structure. By adjusting these parameters, the desired cell patterns and densities are achieved without requiring additional manufacturing steps.
