Golf Club Head Compounded Transfer Layer for Pattern Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional golf club manufacturing process is inefficient due to the need for multiple painting and baking operations to achieve multiple colors, resulting in prolonged production time and paint waste, and additional processes for pattern transfer and protection coating, which complicates the manufacturing and reduces productivity.
Innovation Solution
A compounded transfer layer is formed on the golf club head, comprising a base layer, a dye layer, and a protection layer, where the dye layer is sandwiched between the base layer and the protection layer, allowing for a single process of water or heat transfer printing to create patterns and provide protection, thereby simplifying the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple painting and baking operations are used to achieve multiple colors, then the pattern quality is improved, but the production time is prolonged and paint waste increases
Solution Approach 1:
The patent combines multiple painting operations into a single transfer printing process. The transfer layer is pre-printed with multiple colors and patterns in a factory setting, then transferred to the golf club head in one operation, replacing the conventional multi-step painting and baking process.
Solution Approach 2:
The patent performs the painting operation in advance by pre-printing the transfer layer with all required colors and patterns before transfer. This preliminary action allows multiple colors to be applied simultaneously rather than sequentially during the actual manufacturing process.
2Reliability
If a pattern layer and protection coating are applied separately, then the pattern protection is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent merges the pattern layer and protection coating into a single integrated transfer layer. The transfer layer is constructed with a bottom layer containing the pattern and a top layer providing protection, which are applied simultaneously in one transfer operation rather than as separate steps.
Solution Approach 2:
The transfer layer is designed as a composite structure with a bottom layer (containing the pattern) and a top layer (providing protection). This composite material approach allows both pattern and protection functions to be achieved within a single integrated component.
3Manufacturing precision
If multiple layers are applied sequentially, then the pattern visibility is improved, but the number of manufacturing steps increases
Solution Approach 1:
The patent combines multiple functional layers into a single transfer layer that is applied in one operation. The transfer layer integrates the bottom layer (for pattern visibility) and top layer (for protection), eliminating the need for sequential application of separate layers.

Function Achieved in This Case
This approach enables the formation of a multiple-layered structure on the golf club in a single process, significantly increasing production rate and simplifying the manufacturing process while maintaining clear pattern visibility through the transparent protection layer.
Implementation Method 1
a pattern layer is directly transferred onto the predetermined area of the golf club by way of water transfer printing or heat transfer printing
Implementation Method 2
a pattern layer is directly transferred onto the predetermined area of the golf club by way of water transfer printing or heat transfer printing
Implementation Method 3
