Replaceable Putter Face Insert via Mechanical Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing putters have difficulty in replacing face inserts without causing damage to the insert or the putter body, as they are typically permanently bonded, limiting golfer options for changing face types.
Innovation Solution
A golf club head design featuring a structure with cavities, support rings, and mechanical fasteners that allow for the reversible attachment of a face insert, enabling easy replacement without damaging the putter body, using a combination of threaded bores, flange portions, and sealing gaskets to secure the insert flush with the front surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If face inserts are permanently bonded in putters, then the attachment strength is improved, but the replaceability and flexibility deteriorate
Solution Approach 1:
The putter head is divided into separate components: a body, a replaceable face insert, support rings, and mechanical fasteners. This segmentation allows the face insert to be detached and replaced while maintaining a strong attachment when installed, resolving the contradiction between permanent bonding strength and replaceability.
Solution Approach 2:
The attachment system transitions from a static permanent bond to a dynamic reversible connection using mechanical fasteners (screws or bolts). This allows the face insert to be securely fixed during use but easily removed when replacement is needed, achieving both strong attachment and replaceability.
2Stability of the object's composition
If face inserts are permanently bonded, then the structural integrity is improved, but the ease of repair and maintenance deteriorate
Solution Approach 1:
The putter head includes pre-installed support rings and threaded bores that prepare the structure for face insert attachment. This preliminary preparation ensures structural integrity is maintained while enabling easy replacement without requiring complex removal procedures or damaging the putter body.
Solution Approach 2:
Support rings act as intermediaries between the face insert and the putter head body. These rings provide a stable mounting surface that maintains structural integrity while allowing the mechanical fasteners to securely attach and easily remove the face insert, facilitating maintenance without damage.
3Adaptability or versatility
If mechanical fasteners are used for face insert attachment, then the replaceability is improved, but the device complexity increases
Solution Approach 1:
The mechanical fastener system serves multiple functions: it attaches the face insert securely, provides alignment through threaded bores, and enables easy removal. This multi-functionality achieves high replaceability without proportionally increasing complexity, as the same components serve several purposes in the attachment process.
Solution Approach 2:
The face insert and support rings are designed to self-align during installation, with the threaded bores and flange portions guiding the mechanical fasteners into correct positions. This self-alignment reduces the complexity of precise assembly while maintaining easy replaceability for the user.

AI summary
A golf club head, preferably a putter head, comprising a replaceable face insert is disclosed herein. The golf club head comprises a body with face cavity and a secondary cavity in communication with, and disposed behind, the face cavity, and at least one opening extending through a top or sole portion into the secondary cavity. The replaceable face insert comprises a striking portion and a support structure extending from a rear surface of the striking portion. The support structure is received within the secondary cavity and the striking portion is received within the face cavity, and then a rod or bolt is inserted through the opening and through the support structure to reversibly secure the face insert to the body. A linear bearing may be disposed within the support structure to receive the rod or bolt.
