Rotatable Member Ball for Adjustable Hand Therapy Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for physical therapy, rehabilitation, and strengthening exercises for the hands, arms, wrists, shoulders, elbows, or fingers lack versatility and adjustable resistance, limiting their effectiveness in targeting specific muscles and tissues.
Innovation Solution
A device comprising a ball with a stem and a rotatable member that can be adjusted for resistance, allowing users to perform exercises by rotating the member with their fingers, providing varying levels of resistance and muscle engagement by altering the position of the rotatable member relative to the ball.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current physical therapy methods are used, then exercises can be performed, but versatility and adjustable resistance are limited
Solution Approach 1:
The device combines a ball, stem, and rotatable member into a single apparatus that can perform multiple therapeutic functions. The rotatable member can be positioned at various distances from the ball center, enabling different exercise types and resistance levels, thus providing universal applicability for hand, wrist, and arm rehabilitation without requiring multiple separate devices.
Solution Approach 2:
The rotatable member is designed to rotate around the stem, allowing dynamic adjustment of resistance and exercise intensity. The rotational mechanism enables users to vary the exercise parameters during use, transforming a static device into a dynamic one that adapts to different rehabilitation stages and user needs.
2Adaptability or versatility
If fixed resistance exercises are used, then simple exercises can be performed, but muscle engagement is limited
Solution Approach 1:
The device allows users to pre-position the rotatable member at specific distances from the ball center before performing exercises. This preliminary positioning enables customization of resistance and muscle engagement levels according to individual rehabilitation needs, while maintaining ease of operation through simple rotational movements.

AI summary
The invention relates to a device used for physical therapy, rehabilitation, or strengthening of the hands, arms, wrists, shoulders, elbows, or fingers of a user. The device is a ball with a stem extending from a surface of the ball, and a rotatable member that is rotatably engaged with the stem. The physical therapy, rehabilitation, or strengthening exercises are performed when the user holds the ball in the user's hand while using the fingers of that hand to rotate the rotatable member on the stem.
