Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club head technologies face challenges in enhancing playability characteristics while managing weight and mass distribution, particularly in redistributing mass at high stress locations without compromising structural resilience.
Innovation Solution
The implementation of a golf club face plate with an internal cell lattice structure, comprising an inner skin, an outer skin, and a midsection with a cell lattice that is fully bounded between the skins, allowing for weight reduction through diffusion bonding without compromising strength or durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mass is redistributed at high stress locations to enhance playability characteristics, then playability is improved, but structural resilience may be compromised
Solution Approach 1:
The face plate is divided into multiple layers (outer skin, inner skin, and one or more midsection layers) with a cell lattice structure in the midsection. This segmentation allows independent optimization of each layer's function while maintaining overall structural integrity, enabling mass redistribution without compromising strength.
Solution Approach 2:
The face plate uses a composite structure combining solid skin layers with a cellular midsection lattice. This composite design provides both the strength of solid materials and the weight reduction benefits of cellular structures, resolving the contradiction between playability enhancement through mass redistribution and structural resilience maintenance.
2Weight of moving object
If weight is reduced in the face plate to allow mass redistribution, then playability is enhanced, but structural integrity may be compromised
Solution Approach 1:
The midsection layers incorporate a cell lattice structure with controlled porosity, creating void spaces that reduce material usage and overall weight. The cellular geometry maintains structural strength while enabling significant weight reduction for mass redistribution to strategic locations.
Solution Approach 2:
By segmenting the face plate into outer skin, inner skin, and cellular midsection layers, the design allows weight reduction in the midsection while maintaining integrity through the solid skin layers. This segmentation enables selective weight management without compromising overall structural strength.
3Adaptability or versatility
If the face plate structure is modified to enable mass redistribution, then playability characteristics improve, but manufacturing complexity increases
Solution Approach 1:
The face plate is constructed as separate layers (outer skin, inner skin, midsection layers) that can be manufactured independently and then assembled. This segmentation simplifies the manufacturing of complex cell lattice structures by allowing modular production and assembly, reducing overall manufacturing complexity while enabling mass redistribution.
Solution Approach 2:
The cell lattice structure is nested within the midsection layers, which are themselves nested between the outer and inner skins. This nested arrangement allows complex geometries to be achieved through hierarchical structuring, simplifying the manufacturing process by building complexity layer by layer rather than creating monolithic complex structures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution achieves a weight reduction of up to 25% in the face plate while maintaining structural integrity, allowing for improved playability characteristics and the redistribution of discretionary mass to enhance the club head's center of gravity and moment of inertia, leading to increased ball speed and forgiveness.
Implementation Method 1
The midsection layers can be merged together into a single integral piece of material via diffusion bonding
