Elastic Suspension Straps for Dynamic Exercise Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension exercise devices require frequent reconfiguration to change the difficulty of exercises, which is inefficient and cumbersome.
Innovation Solution
A multi-use elastic exercise device with interconnected strap portions and an anchoring system that allows for easy adjustment of loops to vary the angle and leverage, eliminating the need for constant reconfiguration by using elastic materials with controlled elongation to facilitate dynamic stretching and resistance training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rigid straps with fixed anchor points are used for suspension exercises, then the device provides stable support, but the device requires constant reconfiguration to change exercise difficulty
Solution Approach 1:
The patent employs elastic straps that can dynamically stretch and retract, allowing the anchor points and strap lengths to automatically adjust during exercise movements. This dynamic elasticity eliminates the need for manual reconfiguration while maintaining stable support throughout the range of motion.
Solution Approach 2:
The elastic material properties of the straps enable continuous parameter changes in strap length and tension force based on the exercise position and user body weight distribution. This allows exercise difficulty to be adjusted simply by changing body position rather than reconfiguring the device structure.
2Adaptability or versatility
If multiple coupling components and adjustable straps are provided to vary leverage, then exercise versatility is improved, but setup time and operational complexity increase
Solution Approach 1:
The elastic straps serve multiple functions simultaneously: they provide suspension support, enable leverage variation through their elastic deformation, and act as the connection medium between user and anchor points. This multi-functionality eliminates the need for separate coupling components and adjustment mechanisms.
Solution Approach 2:
The elastic straps automatically adjust their effective length and tension based on the exercise position and applied load, providing self-regulating leverage variation without requiring user intervention for setup or adjustment. The system serves itself by using the exercise motion to configure the optimal strap configuration.
3Reliability
If elastic materials with controlled elongation are used, then safe deceleration is achieved, but the device becomes more complex
Solution Approach 1:
The elastic straps are designed with controlled elongation properties that provide progressive resistance and deceleration before the user reaches the end of their movement range. This beforehand cushioning effect prevents sudden stops and reduces impact forces on joints and muscles.
Solution Approach 2:
The patent uses composite elastic materials that combine high strength with controlled elasticity, integrating multiple material properties into a single strap component. This eliminates the need for separate cushioning mechanisms while maintaining reliability and safety.

AI summary
An exercise device includes a first strap portion having a first elongate portion and a second elongate portion joined together along a common longitudinal axis at varying points to define a first plurality of loops, a second strap portion having a third elongate portion and a fourth elongate portion joined together along a second common longitudinal axis at varying points to define a second plurality of loops, and an anchoring device. The first strap portion and the second strap portion are coupled to one another and the anchoring device is configured to hold or secure the coupled first and second strap portions such that the first plurality of loops and the second plurality of loops extend substantially symmetrically away from the anchoring device.
