Stretch Exercise Tool With Segmented Elastic Finger Rings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stretch exercise tools fail to effectively promote blood circulation in the hands and fingers due to the lack of direct elastic force application, leading to potential blood flow deterioration and capillary function decline.
Innovation Solution
A stretch exercise tool featuring non-stretchable flexible bands with stretchable elastic rings, where the rings are divided into finger hook rings with slits for adjustable fit and elasticity, allowing for adjustable tension and compression to improve blood flow by applying repetitive stimulation to capillaries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a non-stretchable flexible band with elastic rings is used to apply tension, then muscle strengthening is achieved, but the hand or fingers may be rigidly tightened or excessively compressed causing blood flow deterioration
Solution Approach 1:
The elastic ring is divided into multiple finger hook rings by cutting slits, allowing each ring to independently wrap around and stimulate individual fingers or toes. This segmentation enables distributed compression rather than concentrated rigid tightening, preventing blood flow deterioration while maintaining muscle strengthening effect.
Solution Approach 2:
The elastic rings are designed with specific material properties (rubber or thermoplastic elastomer) and geometric parameters (constant width, slit depth not reaching one end) to provide elastic compression rather than rigid tightening. The slits create flexible finger hook rings that can adapt to the shape of fingers and toes, applying gentle repetitive compression to promote blood circulation.
2Productivity
If the stretchable member is extended to receive tensile force, then exercise effectiveness is improved, but the elastic force does not directly act on the grip or hand causing insufficient peripheral blood flow stimulation
Solution Approach 1:
The finger hook rings serve as intermediaries between the elastic ring and the hand/fingers. When the elastic ring is stretched, the finger hook rings are compressed against the fingers and toes, directly transmitting elastic force to the peripheral tissues. This intermediary mechanism enables both exercise effectiveness and adequate blood circulation stimulation.
Solution Approach 2:
The finger hook rings are made of flexible elastic material that can deform and conform to the shape of fingers and toes. This flexibility allows the elastic force to be evenly distributed across the peripheral tissues, providing effective stimulation for blood circulation while maintaining comfort and preventing rigid compression.
