Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rehabilitation methods for hand injuries are cumbersome, offer limited tension adjustment, and primarily focus on either flexion or extension, failing to provide customizable tension for individual fingers and both palmer and dorsal muscle strengthening during normal and sports activities.
Innovation Solution
A variable tension rehabilitation glove with adjustable tension bands that can be worn during daily and sports activities, allowing customizable tension for each finger and reversible resistance for both flexion and extension, with a convertible design to accommodate both palmer and dorsal muscle strengthening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional rehabilitation devices are used to provide tension during hand flexion or extension, then muscle strengthening is achieved, but the devices are bulky and cumbersome making them unsuitable for normal daily activity or sports activities
Solution Approach 1:
The tensioning system is segmented into individual tension bands for each finger, allowing independent adjustment and reducing overall bulk. Each finger portion has its own tension band that can be adjusted separately, eliminating the need for a monolithic bulky structure.
Solution Approach 2:
The glove incorporates adjustable tension bands with movable tension devices that allow dynamic adjustment of resistance levels. This dynamic capability enables the glove to adapt to different rehabilitation stages while maintaining a compact form factor suitable for everyday wear.
2Adaptability or versatility
If conventional rehabilitation devices provide fixed tension, then manufacturing is simplified, but the user cannot adjust tension levels as rehabilitation progresses requiring multiple devices
Solution Approach 1:
The tension bands incorporate movable tension devices with adjustable mechanisms that allow users to change tension levels as rehabilitation progresses. This dynamic adjustment capability eliminates the need for multiple fixed-tension devices while maintaining manageable complexity through standardized components.
Solution Approach 2:
The glove design integrates multiple functions into a single device: it provides tension for both flexion and extension, allows individual finger adjustment, and accommodates different rehabilitation stages. This multi-functionality reduces the need for multiple separate devices.
3Adaptability or versatility
If conventional rehabilitation devices apply uniform tension to all fingers, then the device structure is simplified, but individual finger injury requirements cannot be met
Solution Approach 1:
The glove divides the tensioning system into separate, independent tension bands for each finger. This segmentation allows each finger to receive customized tension levels according to its specific injury or rehabilitation needs, while the modular nature keeps the overall device structure manageable.
Solution Approach 2:
Each finger portion has its own adjustable tension band with independent tension control, allowing local customization of tension levels. This local quality approach enables precise control over the tension applied to each finger without requiring complex centralized control mechanisms.
4Adaptability or versatility
If conventional rehabilitation devices focus on either flexion or extension, then the device design is simplified, but both palmer and dorsal muscles cannot be strengthened with one device
Solution Approach 1:
The glove incorporates a convertible structure that can be dynamically reconfigured to provide tension for both flexion and extension exercises. The adjustable tension bands and movable tension devices allow the same glove to adapt to different exercise types, eliminating the need for separate flexion and extension devices.
Solution Approach 2:
The rehabilitation glove is designed to perform multiple functions: it can strengthen both palmer and dorsal muscles, accommodate both flexion and extension exercises, and provide individualized treatment for each finger. This multi-functionality consolidates what would traditionally require multiple separate devices.
