Portable Resistance Bar With Nested Bands for Safe Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise equipment is often bulky, not portable, and unsafe, with handles that cause discomfort and complications due to loose resistance bands, lacking variety in resistance combinations, and requiring unnecessary moving parts.
Innovation Solution
A portable exercise device with nested resistance bands inside a bar member, secure handles, and adjustable length, providing multiple resistance levels through combinations of bands, ensuring safety and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If resistance bands are placed outside the main apparatus, then the device is simpler to manufacture, but the appearance becomes sloppy and safety is compromised due to whip hazard
Solution Approach 1:
The resistance bands are nested inside the hollow bar member, with the bands stored within the hollow interior space. This eliminates the whip hazard and sloppy appearance while maintaining manufacturing simplicity, as the bands are contained within the existing bar structure rather than requiring additional external compartments.
2Weight of moving object
If handles are made small and flimsy, then the device is more portable, but the resistance bands come into uncomfortable contact with the user
Solution Approach 1:
The handles are nested within the hollow bar member when not in use, keeping the device compact and portable. During exercise, the handles extend outward to provide adequate size and comfort, preventing resistance bands from contacting the user's body. This dual-state design maintains portability while ensuring comfort during operation.
3Device complexity
If one or two flexible elements are used, then the device is simpler, but the variety of resistance combinations is insufficient
Solution Approach 1:
The device incorporates multiple resistance bands (typically three or more) that can be dynamically combined in various configurations. Users can attach different numbers and combinations of bands to the handles, allowing customization of resistance levels for different exercises and fitness levels, thereby providing versatility without excessive complexity.
4Adaptability or versatility
If pulleys or small moving parts are added, then the variety of resistance combinations is improved, but the apparatus becomes more complicated, less reliable, and harder to produce
Solution Approach 1:
The invention extracts and eliminates unnecessary small moving parts such as pulleys from the system. Instead, it uses a direct attachment mechanism where resistance bands connect to handles and the hollow bar member through simple loops or attachment points. This maintains versatility in resistance combinations while significantly reducing complexity and improving reliability.
5Ease of operation
If the user steps on the flexible element, then the device is easier to operate, but unnecessary wear and tear occurs
Solution Approach 1:
The invention introduces a dedicated securing member (handle with footrest) as an intermediary between the user's foot and the resistance band system. This allows the user to step on the footrest for stability during exercises without directly contacting and damaging the resistance bands, thereby maintaining ease of operation while preserving durability.
