Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for tennis elbow, such as non-surgical methods and post-surgical rehabilitation, lack effective exercise devices that provide adjustable resistance and versatility for upper limb rehabilitation.
Innovation Solution
A handheld exercise device with a main body featuring a rotatable hand grip and mode selector, allowing for different configurations and adjustable resistance, enabling users to perform exercises with both hands and accommodating external weights for varied resistance levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotatable hand grip is provided for exercise movements, then the range of motion and exercise versatility is improved, but the device complexity increases due to mode selector and configuration switching mechanisms
Solution Approach 1:
The patent combines multiple gripping means (first rotatable grip, second fixed grip, third rotatable grip) into a single integrated device body, allowing different grip configurations to be used with the same resistance mechanism. This merging approach provides exercise versatility without proportionally increasing overall device complexity, as the resistance system serves all grip types.
Solution Approach 2:
The device is designed with universal functionality where a single device body with one resistance mechanism can accommodate multiple grip configurations (rotatable and fixed). The mode selector allows the same device to perform different exercise functions, making the resistance system multi-functional and reducing the need for separate devices for different exercise types.
2Reliability
If adjustable resistance is provided through spring mechanisms, then the effectiveness of rehabilitation treatment is improved, but the device complexity increases due to multiple springs and adjustment mechanisms
Solution Approach 1:
The resistance system is segmented into multiple independent compression springs (first compression spring, second compression spring) that can be independently adjusted. Each spring can be positioned at different locations along the longitudinal axis, allowing granular control over resistance characteristics without requiring a completely complex integrated adjustment system.
Solution Approach 2:
The device employs dynamic resistance adjustment where the compression springs can be repositioned along the longitudinal axis to change the resistance profile during exercise. The mode selector dynamically switches between different grip configurations, and the resistance characteristics can be modified by adjusting spring positions, creating a dynamic and adaptable treatment system.
3Adaptability or versatility
If multiple gripping means are provided for different exercise configurations, then the adaptability for various rehabilitation exercises is improved, but the ease of operation decreases due to mode switching requirements
Solution Approach 1:
The device incorporates a mode selector that allows users to independently switch between different grip configurations (rotatable/fixed modes) without requiring external assistance or complex setup procedures. Each gripping means is self-contained and can be independently activated, enabling users to self-adjust the device for different exercise needs.
Solution Approach 2:
The mode selector acts as an intermediary mechanism that simplifies the transition between different exercise configurations. Instead of requiring direct manual manipulation of multiple independent systems, the mode selector provides a unified control interface that mediates the switching between rotatable and fixed grip modes, making the operation more intuitive and easier to use.
