Weight Lifting Band Structure to Prevent Sagging and Slipping
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 effectiveness of weight lifting support.
Innovation Solution
A weight lifting support device with a restrictive panel and elongated member that restricts arm movement in the longitudinal direction, using a relatively inelastic fabric and elastic loops to prevent sagging and improve 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 support weight lifting, 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 portion (loops) that provides stretch and support, and an inelastic portion (restrictive panel) that prevents excessive sagging. This segmentation allows each portion to perform its specific function - the elastic loops accommodate weight lifting while the inelastic panel maintains stability by limiting downward displacement.
Solution Approach 2:
Different portions of the band have different material properties: the loops are made from elastic material to provide stretch and support, while the restrictive panel is made from inelastic material to prevent sagging. This local differentiation of material qualities allows the band to simultaneously provide both elasticity for weight support and stability for performance enhancement.
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 band is segmented into elastic loops for support and an inelastic restrictive panel for position stability. The inelastic portion acts as an anchor that prevents the band from sliding down the arms during exercise, while the elastic portions maintain their support function.
Solution Approach 2:
The restrictive panel uses inelastic material specifically at the portion that contacts the arm to prevent slipping, while the loops use elastic material to provide support. This local quality differentiation solves the slipping problem without compromising support capability.
3Strength
If the band material is made to be more elastic to increase support, then the band can lift more weight, but the sagging increases causing unstable feel
Solution Approach 1:
The band separates weight support function (elastic loops) from stability function (inelastic restrictive panel). The elastic portions can be designed with high elasticity to support heavy weights, while the inelastic panel prevents excessive sagging, eliminating the trade-off between weight support and stability.

AI summary
Embodiments described herein are directed to a weight lifting support device. The weight lifting support device includes a panel having a pair of side edges and an elongated member. The elongated member has a first end and an opposite second end. The elongated member is coupled to the panel to define two independent loops. Each of the two independent loops has an opening on positioned either side of the panel and each of the two independent loops and openings thereof extend beyond a respective side edge of the panel. The two independent loops have an elasticity and the panel has a restriction elasticity less than the elasticity of each of the two independent loops.
