Exercise Bar With Retractable Bands for Safer Resistance Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise equipment is bulky, non-portable, and unsafe, often causing discomfort and injury due to flimsy handles and exposed resistance bands, lacking variety in resistance levels, and requiring unnecessary moving parts.
Innovation Solution
A portable exercise device with retractable resistance bands stored inside a hollow bar, featuring adjustable handles with multiple sides for grip and anchoring, providing customizable resistance levels and safe usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If resistance bands are stored outside the main apparatus, then the device is easier to access, but the appearance becomes sloppy and creates whip hazards
Solution Approach 1:
The resistance bands are stored inside the hollow bar member, with each band nested within the bar's interior space. This containment eliminates the whip hazard and sloppy appearance while keeping the bands accessible during exercise through openings or access points in the bar structure.
2Weight of moving object
If flimsy handles are used, then the device is lighter and more portable, but the resistance bands come into uncomfortable contact with the user
Solution Approach 1:
The handle is segmented into multiple sides, with at least one side formed of a rigid material providing a barrier between the user's hand and the resistance band. This segmentation allows the handle to remain lightweight while the rigid portion prevents uncomfortable band contact during exercise.
3Device complexity
If one or two flexible elements are used, then the device is simpler, but it cannot provide the variety of resistance combinations desired by users
Solution Approach 1:
Multiple resistance bands with different resistance levels are integrated into a single bar member, allowing users to select different bands or combine them for various resistance levels. This multi-functional design provides diverse resistance combinations while maintaining a simple, unified device structure.
4Adaptability or versatility
If pulleys or small moving parts are added, then the device can provide more resistance combinations, but the apparatus becomes more complicated, less reliable, and harder to produce
Solution Approach 1:
The patent extracts and eliminates unnecessary small moving parts such as pulleys from the design. Instead, multiple resistance bands are directly attached to the bar member, providing resistance combinations through the bands themselves rather than through complex mechanical systems, thereby improving reliability and ease of manufacture.

AI summary
A portable exercise device for use in resistance training programs is provided, which can comprise: a hollow structure; multiple resistance bands, each shorter than the hollow structure; multiple anchor members for securing the resistance bands to the hollow structure; multiple attachable and detachable handles; wherein one end of each resistance band is coupled to an anchor; wherein an opposing end of each resistance band is operably configured for attachment to a handle; such that each resistance band is contained completely within the hollow structure during rest and is capable of extending outside the hollow structure during use when attached to a handle. Such devices can be used by attaching a handle to a resistance band at each end of the hollow bar, gripping the bar with hands, placing feet in the handles, and moving the bar away from the feet to create resistance in the bands thereby exercising the user's body. Such devices can also be used by attaching a handle to the resistance band at each end of the hollow bar, whereby the handle is three-sided and each side serves a different adapted function; for example, one side may be configured for gripping by a user's hand, one side may be configured for engaging by the user's foot, and one side may be configured to anchor to an anchoring structure.
