Golf Club Face Insert Using Amorphous Ceramic Slurry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf club heads fail to provide a durable and effective strike surface that reduces spin and enhances launch angle and carry distance, with existing coatings like PTFE being too soft and prone to mechanical engagement with the golf ball, leading to unintended spin and limited durability.
Innovation Solution
A golf club head with an insert made from a durable, injection moldable material such as polymeric Acetal or amorphous ceramic, featuring a smooth or textured surface with specific properties like hardness and compressive strength, applied as a liquid slurry and processed to create a glassified ceramic surface with microgrooves, which reduces spin and increases kinetic energy transfer for improved performance.

Engineering Contradiction Analysis
1Object-generated harmful factors
If PTFE coating is used on the golf club face, then spin is reduced, but the coating is too soft and prone to mechanical engagement with the golf ball, leading to unintended spin and limited durability
Solution Approach 1:
The patent changes the material parameters from soft PTFE to harder materials such as ion-exchange resin, polyacetal, polyurethane, or ceramic materials. This parameter change maintains the spin-reducing effect while eliminating the mechanical engagement problem that causes unintended spin and reduces durability.
Solution Approach 2:
The patent employs composite material structures, particularly ceramic materials combined with bonding layers or transition layers, to achieve both the spin-reducing surface properties and the durability required to withstand repeated golf ball impacts without degradation.
2Productivity
If the clubface is made slippery to reduce spin, then launch angle and carry distance increase, but the surface becomes less durable and conforms to fewer USGA requirements
Solution Approach 1:
The patent changes the surface material parameters to achieve the appropriate balance between slipperiness for spin reduction and hardness for durability. Materials like ion-exchange resin, polyacetal, and ceramic provide the necessary combination of low friction and high durability to meet both performance and USGA requirements.
3Use of energy by moving object
If a smooth surface is applied to reduce spin, then kinetic energy transfer improves, but the surface may not withstand repeated impacts without degradation
Solution Approach 1:
The patent uses composite material structures where a smooth, spin-reducing surface layer is combined with a durable bonding layer or transition layer. This composite structure maintains excellent kinetic energy transfer while providing the impact resistance needed to withstand repeated golf ball impacts without surface degradation.

AI summary
A method of enhancing surface strike performance, includes providing a club head having a face surface and a receiving portion recessed into the club face. The receiving portion is configured to receive a strike surface material. The surface strike material is an amorphous ceramic material which is inserted as an inlay into the receiving portion as a liquid slurry. The slurry is distributed evenly within said receiving portion forming a uniform layer of ceramic material filling said receiving portion. Microgrooves are added to the ceramic material in a vertical direction to further increase the strike performance of the club head.
