Golf Club Head Face Plate Non-Supported Region
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads face challenges in further improving rebound performance, which is essential for enhanced ball striking efficiency.
Innovation Solution
A golf club head design featuring a face plate with a partially interrupted discontinuity in its receiving surface, allowing for a non-supported region that is not directly supported by the head main body, and fixed using plastic deformation to enhance flexibility and rebound performance, with specific material choices and structural features to optimize resilience and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the face plate is fully supported by the head main body through welding, then the structural strength and durability are improved, but the rebound performance deteriorates due to heat-induced deterioration and reduced flexibility
Solution Approach 1:
The receiving surface is divided into multiple regions: a first region with continuous support for structural strength, and a second region with interrupted discontinuity for enhanced rebound performance. This segmentation allows different portions of the face plate to have different support characteristics, resolving the contradiction between strength and rebound performance
Solution Approach 2:
Different regions of the receiving surface are given different qualities: the first region provides continuous support for durability, while the second region provides localized non-supported areas that enhance flexibility and rebound performance in specific zones of the face plate
2Reliability
If the face plate is made thinner to increase flexibility and rebound performance, then the rebound performance is improved, but the structural strength deteriorates
Solution Approach 1:
The support structure is segmented into continuous and interrupted regions, allowing the face plate to be thinner overall while maintaining strength where needed (first region) and achieving flexibility where needed (second region with non-supported areas)
Solution Approach 2:
The golf club head uses a composite structure combining the face plate with the head main body through a hybrid support system that integrates both continuous and interrupted support regions, achieving properties that neither a fully thick nor fully thin uniform structure could provide alone
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
The design significantly improves rebound performance by increasing the flexibility of the face plate, particularly in the non-supported regions, leading to better ball striking efficiency and maintaining durability without heat-induced deterioration from welding.
Implementation Method 1
the face plate is fixed to the head main body by a plastic deformation portion of the head main body
Implementation Method 2
a portion of the plate side surface corresponding to the non-supported region is not directly supported by the head main body

AI summary
A golf club head includes a face plate including a plate front surface constituting a club face, a plate rear surface opposite the plate front surface and having an outer peripheral portion, and a plate side surface, and a head main body being provided with an opening to receive the face plate and a receiving surface formed around a periphery of the opening to support the outer peripheral portion of the plate rear surface. The receiving surface is formed with a partially interrupted discontinuity so that the outer peripheral portion has a non-supported region that is not directly supported by the head main body. A portion of the plate side surface corresponding to the non-supported region is not directly supported by the head main body. The face plate is fixed to the head main body by a plastic deformation portion of the head main body.
