Rotatable Grip Exercise Device with Mode Selector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current exercise devices are inadequate for the non-surgical treatment and rehabilitation of tennis elbow (lateral epicondylopathy) and other upper limb rehabilitation needs, lacking adjustable resistance and versatile configurations.
Innovation Solution
An exercise device with a rotatable hand grip, mode selector, and tensioning means using compression springs to provide adjustable resistance, allowing for multiple grip configurations and optional weight attachment for varied exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotatable grip is provided for exercise movements, then the device enables rehabilitation exercises for tennis elbow, but the grip rotation may cause instability or lack of support during exercise
Solution Approach 1:
The device employs a mode selector mechanism that allows dynamic switching between two grip configurations: a rotatable configuration for rehabilitation exercises and a locked fixed configuration for stability. The mode selector enables the user to transition between these states, providing both adaptability for different exercise phases and stability when needed.
2Force
If tensioning means with compression springs are added to provide resistance, then the device offers adjustable resistance for rehabilitation, but the device complexity increases
Solution Approach 1:
The compression springs are positioned to automatically engage and disengage based on the grip rotation and mode selector position. The spring mechanism self-regulates the resistance force based on the exercise configuration, eliminating the need for complex external adjustment mechanisms while providing variable resistance.
3Adaptability or versatility
If a mode selector means is provided to switch between configurations, then the device offers versatile exercise options, but the ease of operation is reduced due to additional controls
Solution Approach 1:
The mode selector means is integrated with the grip structure itself, combining the configuration switching function with the existing grip components. This integration allows the user to change configurations as a natural part of the exercise motion, reducing the cognitive and physical burden of separate control operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively supports non-surgical treatment and rehabilitation of tennis elbow and other upper limb conditions by offering adjustable resistance and versatile exercise options, enhancing user engagement and rehabilitation outcomes.
Implementation Method 1
The tensioning means comprises a first compression spring positioned within the main body. The first compression spring compresses during rotation of the grip to provide resistance.
