Deflectable Golf Club Badge Insert for Gap Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Iron-type golf club heads often have unsightly gaps around badge inserts due to variances in cavity size during the investment casting process, as badges are designed to be undersized to avoid interference with the cavity's peripheral sidewall.
Innovation Solution
A deflectable badge insert with a central portion and a peripheral edge portion that conforms to the cavity's inner peripheral surface, forming a press-fit engagement to eliminate gaps, using materials like metals and polymers with a living hinge or elastomers for deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the badge is designed to be undersized relative to the cavity, then the badge does not interfere with the peripheral sidewall of the cavity, but unsightly gaps appear around the periphery of the badge
Solution Approach 1:
The badge incorporates a deflectable peripheral portion that can dynamically adjust its position. This deflectable portion bends or deflects during installation to accommodate cavity size variations, allowing the badge to maintain continuous contact with the cavity's inner peripheral surface despite manufacturing tolerances, thereby eliminating gaps without requiring precise cavity dimensions
Solution Approach 2:
The badge design changes the physical state or configuration of its peripheral portion by making it deflectable. This allows the peripheral portion to change its effective dimensions or position in response to cavity size variations, enabling the badge to adapt to different cavity sizes and eliminate gaps through parameter adjustment rather than maintaining fixed dimensions
2Area of stationary object
If the badge is designed to be the nominal size of the cavity, then the badge can fully utilize the cavity space, but the badge interferes with the peripheral sidewall of the cavity due to size variances
Solution Approach 1:
The deflectable peripheral portion allows the badge to dynamically adjust during installation. When the cavity is larger than nominal, the deflectable portion bends to maintain contact with the cavity wall. When the cavity is smaller, the deflectable portion deflects inward to avoid interference, ensuring reliable installation across varying cavity dimensions while maintaining full badge coverage
3Ease of manufacture
If the badge is installed offset toward one side of the cavity, then the badge avoids interference with the peripheral sidewall, but gaps appear around the periphery of the badge
Solution Approach 1:
The deflectable peripheral portion enables the badge to be installed centrally in the cavity while automatically adapting to cavity size variations. During installation, the deflectable portion bends to accommodate the cavity walls, allowing centralized positioning that eliminates peripheral gaps without requiring offset installation or complex adjustment procedures
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 solution ensures a secure, gap-free fit of the badge insert within the cavity, maintaining aesthetic appeal and potential performance benefits like vibration damping, regardless of cavity size variations.
Implementation Method 1
At least a portion of the peripheral edge portion comprises a deflectable portion having a shape corresponding to and contacting a corresponding section of the inner peripheral surface of the cavity, with the deflectable portion being retained in a deflected state by contact with the corresponding section of the inner peripheral surface of the cavity

AI summary
The present disclosure concerns embodiments of a badge or insert for a golf club head that can eliminate undesired gaps between the insert and the peripheral sidewall of the cavity that receives the insert. In one embodiment, a golf club head comprises a main body comprising a cavity, which defines a central surface and an inner peripheral surface at least partially surrounding the central surface. An insert comprises a central portion and a deflectable portion coupled to and extending along a peripheral edge section of the central portion. The deflectable portion has a shape corresponding to and contacting a corresponding section of the inner peripheral surface of the cavity. The deflectable portion forms a press-fit engagement with the corresponding section of the inner peripheral surface of the cavity that retains the deflectable portion in a deflected state relative to the central portion.
