Adjustable Swingweight with Movable Weight and Flanged Stabilizers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf clubs face difficulties in adjusting swing speed and strength without requiring proficiency, as existing swingweight adjustment methods are cumbersome and do not allow for easy fine-tuning of the center of gravity's position along the axial direction, leading to instability and poor usability.
Innovation Solution
A swingweight system with a support shaft extending along the grip axis, a movable weight secured by a screw mechanism, and flanged bodies at both ends to stabilize the weight and prevent separation, allowing for precise adjustment of the center of gravity by changing the weight's position along the shaft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a swingweight is mounted at a predetermined position using conventional methods (inset or screw), then the swingweight can be securely fixed, but it becomes troublesome to replace and adjust the swingweight position
Solution Approach 1:
The swingweight is designed with a movable configuration along the shaft axis, allowing it to be adjusted to different positions while maintaining secure fixation. The weight can be moved along the shaft and fixed at desired positions using the adjustment mechanism, transforming a static fixed position into a dynamic adjustable position system.
Solution Approach 2:
The swingweight assembly is divided into separable components: the weight body, the adjustment mechanism (screw or inset structure), and the shaft. This segmentation allows the weight to be independently adjusted along the shaft while maintaining secure fixation, enabling easy replacement and repositioning without compromising reliability.
2Device complexity
If the center of gravity position is fixed in conventional golf clubs, then the structure is simple, but it cannot easily adjust swing speed and strength depending on the situation
Solution Approach 1:
The center of gravity position is made dynamic and adjustable along the shaft axis rather than fixed. By moving the swingweight to different positions along the shaft, the center of gravity can be repositioned to adjust swing speed and strength according to different playing situations, while maintaining a relatively simple overall club structure.
Solution Approach 2:
The position parameter of the swingweight along the shaft axis can be changed to adjust the center of gravity location. This parameter change enables the club to adapt swing speed and strength for different situations without requiring complex structural modifications, achieving versatility through simple positional adjustment.
3Adaptability or versatility
If spherical weight materials are housed in a section within the grip, then swingweight adjustment is possible by changing the number of weight materials, but the weight materials move within the section during swing causing unstable center of gravity position
Solution Approach 1:
The swingweight is extracted from the grip section and mounted on the shaft instead. This removes the weight from the movable space within the grip, preventing it from shifting during swing. The weight is now fixed on the shaft at a determined position, ensuring stable center of gravity while still allowing adjustment by changing the number or position of weights on the shaft.
Solution Approach 2:
The shaft acts as an intermediary structure that provides a stable mounting surface for the swingweight. Instead of placing weights directly in the grip section where they can move, the shaft serves as a stable intermediary that holds the weights in fixed positions, preventing center of gravity instability while allowing for adjustment.
4Adaptability or versatility
If the fill ration of spherical weight material is reduced to create eccentric center of gravity at club head side, then swingweight adjustment is possible, but the center of gravity cannot be eccentrically-located at the grip end side
Solution Approach 1:
The swingweight position along the shaft can be dynamically adjusted to create eccentric center of gravity at either the club head side or grip end side. By moving the weight to different positions along the shaft, the center of gravity can be strategically located to achieve the desired swing characteristics, providing versatile adjustment without excessive complexity.
Solution Approach 2:
Instead of adjusting center of gravity position within a limited section (as with spherical weights in a grip section), the weight can be positioned along the entire length of the shaft, adding a dimensional freedom that allows eccentric placement at either end of the club while maintaining simple weight distribution control.
