Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing body weight exercise devices face challenges such as cumbersome strap adjustments, limited configuration options due to fixed anchor points, tangling issues, and annoyance from dangling buckles during use.
Innovation Solution
A body weight exercise device featuring a single rotatable reel with spring-loaded, manually adjustable inelastic straps that can be evenly wound or unwound, combined with a swivel mount for 360° rotation and innovative attachment mechanisms like door mounts and lashing straps for versatile anchoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate buckles are used on each side of the strap for length adjustment, then the strap length can be adjusted, but the adjustment process becomes difficult and time-consuming to achieve equal strap lengths
Solution Approach 1:
The patent combines two separate strap adjustment mechanisms into a single reel system. Both straps are wound around the same reel, allowing simultaneous adjustment of both straps through one operation. The reel rotates in response to pulling on either strap, automatically distributing the adjustment evenly to both sides, thereby eliminating the time and difficulty of coordinating separate adjustments.
Solution Approach 2:
The reel system automatically ensures equal strap length distribution through its mechanical design. When one strap is pulled, the reel rotates and winds or unwinds both straps simultaneously, self-regulating to maintain equal lengths without requiring user intervention to coordinate both sides.
2Adaptability or versatility
If the device is suspended in line with the anchor point, then the strap length can be adjusted, but the device cannot be rotated to different orientations
Solution Approach 1:
The patent introduces a swivel mount that allows the reel assembly to rotate dynamically around the anchor point. This dynamic mounting mechanism enables the device to adapt to different orientations and workout positions while maintaining proper strap tension and alignment, transforming a static suspension system into a flexible, multi-orientable one.
3Adaptability or versatility
If a single length strap is used, then the construction is simple, but the strap can become tangled and shorter lengths cannot be achieved
Solution Approach 1:
The patent replaces the fixed-length strap with a dynamic reel-wound strap system. The straps are wound around the reel, allowing the effective length to be dynamically adjusted by rotating the reel. This enables the straps to be lengthened or shortened as needed while preventing tangling through the organized winding mechanism, transforming a static single-length strap into a versatile, adjustable system.

AI summary
An exercise device (100) is supportable by a swivel mount (116) attached to a karabiner (114) and the swivel mount is arranged to lock under load at 90° increments. The device includes a rotatable reel (103) arranged to have a pair of inelastic straps (113a, 113b) rotationally wound thereabout from opposite directions. The reel is rotatable in conjunction with a locking mechanism consisting of a toothed sprocket wheel (104) secured to the reel and a manually operable slideable shaft (106) that is located within a barrel (107). Slots (136, 139) in the shaft and barrel, respectively, permit rotational movement of the sprocket wheel and, hence, reel (103) so that the straps (113a, 113b) may have their length altered against the bias of a coil spring unit (111). Translational movement of the shaft (106) within the barrel (107) causes the full diameter of the shaft (106) to engage between adjacent teeth of the sprocket wheel to lock the reel (103), thereby preventing further adjustment of the straps (113a, 113b). When the reel is released for rotational movement, so pulling on one or both of the straps against the bias of the spring unit causes the straps to be unwound evenly and reducing the pulling force below that of the spring unit causes the straps to be rotationally wound around the reel from opposite directions.
