Two-Piece Golf Weight Screw Retaining Ring Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club weight screws are prone to breakage and loss due to structural weaknesses, making them inconvenient for golfers to adjust and maintain.
Innovation Solution
A two-piece weight screw design with a retaining ring mechanism that securely attaches to a wrench, preventing vertical movement and allowing horizontal expansion, combined with a unidirectional torque transfer interface between the drive and threaded parts to enhance structural integrity and prevent disengagement during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-piece weight screw design is used, then the structure is simple, but the screw is prone to breakage and loss
Solution Approach 1:
The weight screw is divided into two separate components: a drive portion and a threaded portion. This segmentation allows each part to be optimized independently - the drive portion can be designed for tool engagement while the threaded portion is optimized for insertion and weight adjustment, thereby improving overall reliability and reducing breakage
2Reliability
If a retaining ring mechanism is added to prevent loss, then the screw security improves, but the device complexity increases
Solution Approach 1:
The retaining ring is designed with elastic properties, allowing it to dynamically adapt between expanded and contracted states. When the drive portion is inserted, the retaining ring expands to engage with the wrench cavity, providing automatic retention without requiring additional complex mechanisms
3Ease of manufacture
If the drive and threaded parts are formed separately, then manufacturing flexibility improves, but the assembly complexity increases
Solution Approach 1:
The drive portion and threaded portion are merged through a friction-fit assembly where the drive portion is inserted into the threaded portion. The elastic retaining ring automatically secures the assembly when engaged with the wrench, creating a unified functional unit without requiring complex fastening mechanisms

AI summary
A screw comprising a drive part, a threaded part, and a retaining ring is disclosed herein. Each of the drive part and the threaded part comprises a plurality of interface surfaces that transmit torque from the drive part to the threaded part and prevent the parts from disengaging from one another during use. Each plurality of interface surfaces forms one or more geometric shapes that create additional friction between the drive and threaded parts, and may further include mating pins and holes to prevent the parts from detaching from one another. The retaining ring, which removably connects the screw to a wrench during assembly of the screw with a receptacle, is disposed within a cavity formed when the drive part is assembled with the threaded part.
