Weight Lifting Support With Restriction Panel for Sag Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional weight lifting bands made from elastic material sag and slip during exercises, causing instability and reducing the support provided, especially during upward and outward thrust arm movements, leading to increased strain on the shoulders.
Innovation Solution
A weight lifting support device featuring a restrictive panel and elongated member with independent loops, where the panel has a lower elasticity than the loops, preventing sagging and slippage by restricting movement in the longitudinal direction, and incorporating anti-slip surfaces to maintain stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional weight lifting bands are made from wholly elastic material, then the material can stretch to accommodate movement, but the band sags at the bottom end of lifting movement causing instability
Solution Approach 1:
The weight lifting band is divided into two distinct segments: an elastic elongated member that provides stretch and support, and a restrictive panel with lower elasticity that prevents excessive sagging. This segmentation allows each component to perform its specialized function - the elastic portion accommodates movement while the restrictive panel maintains stability by limiting downward displacement.
Solution Approach 2:
Different portions of the weight lifting band are assigned different elastic properties. The elongated member has high elasticity to allow stretching during exercise, while the restrictive panel has lower elasticity to prevent sagging. This local differentiation of material properties enables the band to simultaneously provide both adaptability and stability in different regions.
2Strength
If conventional weight lifting bands are made from elastic material, then the band can provide support, but the band slips down the arms during lifting
Solution Approach 1:
The restrictive panel is positioned at specific locations on the band where slippage occurs, creating localized zones of higher friction and lower elasticity. This local quality change prevents the band from sliding down the arms during lifting while maintaining the overall elastic support function of the elongated member.
Solution Approach 2:
The restrictive panel acts as an intermediary element between the elastic elongated member and the user's body. It mediates the interaction by providing a non-slip surface that prevents downward movement, while still allowing the elastic member to function beneath it.
3Stability of the object's composition
If the panel has low elasticity to prevent sagging, then stability is improved, but the overall elasticity of the band is reduced
Solution Approach 1:
The band is segmented into elastic and non-elastic portions, allowing the elastic elongated member to provide overall elasticity and adaptability, while the restrictive panel provides localized stability to prevent sagging. Each segment compensates for the limitations of the other.
Solution Approach 2:
The weight lifting band combines materials with different elastic properties - a highly elastic elongated member and a less elastic restrictive panel - to create a composite structure that exhibits both high overall elasticity and localized stability. This composite approach allows the band to prevent sagging while maintaining adequate overall elasticity for exercise performance.
