Articulating Finger Weight System with Dynamic Center of Gravity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing finger weight devices lack flexibility in affixing and removing positions, and do not easily adapt to varying weight requirements, restricting their use in high-velocity movements and causing discomfort during extended use.
Innovation Solution
An articulating weight system with a strap that tightens to adjust the center of gravity, featuring hinged end body portions and cylindrical weight holders, allowing for easy weight adjustment and secure fitting around the finger without restricting circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing finger weight devices use a strap and rigid structure, then they provide weight support, but they lack flexibility for quick affixing and removing
Solution Approach 1:
The device employs a flexible strap that can dynamically adjust to different finger sizes and shapes, allowing quick affixing and removing while maintaining secure fitting through elastic tension and articulating weight sections that move with the finger
2Adaptability or versatility
If existing finger weight devices have fixed weight positions, then they provide stable weight support, but they lack adaptability for varying weight requirements
Solution Approach 1:
The weight support system is divided into multiple articulating weight sections that can independently move and adjust, allowing weights to be positioned at different locations along the finger while maintaining simple individual component design
Solution Approach 2:
The articulating weight sections are nested within the strap structure, with each section capable of independent movement while being integrated into the overall device, allowing weight adjustment without adding external complexity
3Ease of operation
If the center of gravity is not constant during high velocity movements, then the device structure is simple, but it causes discomfort and restricts circulation during extended use
Solution Approach 1:
The articulating weight sections dynamically adjust their position relative to the finger during movement, automatically maintaining the center of gravity in an optimal location even during high velocity movements, while the flexible strap adapts to finger motion without restricting circulation

AI summary
A Finger Weight System have a main central body portion and a pair of end body portions hinged to the main central body portion, allowing the end body portions to flex and hinge away from the main central body portion. A weight holder on each of the body portions for receiving weights. An outwardly bulb-shaped projection located on at least one of the end body portions, wherein the projection is sized to be received in an opening in a strap after the strap has been wrapped around a person's finger. A member hinged to a rear flange member for retaining the strap in position against the main central body portion, the member secured in a locked position against the strap by a front flange member including a tab or upstanding projection that fits into a groove on an end of the member.
