Elastic Strap Exercise Apparatus with Adjustable Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise apparatuses lack versatility and adjustability to provide varying levels of assistance and resistance for users performing exercises like pull-ups and push-ups, particularly for those with different strength levels or rehabilitation needs.
Innovation Solution
A portable exercise apparatus featuring a strap with an elastic portion and adjustable suspension members that can be coupled to a supporting structure, allowing for customizable tension and resistance levels by adjusting the position of the suspension members relative to the strap, forming a U-shape for user positioning that assists in pull-ups and push-ups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing exercise apparatuses are used, then basic exercise functions are provided, but versatility and adjustability for varying assistance and resistance levels are lacking
Solution Approach 1:
The apparatus employs dynamic adjustment mechanisms where suspension members can be repositioned along the strap at different locations. This allows the resistance and assistance levels to be adjusted by changing the position of suspension members relative to the elastic portion, enabling users to customize exercise difficulty without complex mechanical systems
Solution Approach 2:
The strap is divided into distinct functional segments: an elastic portion for providing resistance/assistance and non-elastic portions for attachment. The suspension members can be independently positioned at different locations along these segments, allowing granular adjustment of exercise parameters while maintaining overall system simplicity
2Adaptability or versatility
If adjustable suspension members are added to provide versatility, then assistance and resistance levels can be customized, but device complexity increases
Solution Approach 1:
The same strap and suspension member assembly serves multiple functions: providing elastic resistance during pull-ups, providing assistance during push-ups, and allowing adjustable tension levels. The suspension members can be positioned at different locations to create varying mechanical advantages, enabling one apparatus to replace multiple exercise devices with different fixed resistance levels
