Pivoting Exercise Strap Buckle With Nesting Hook
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to improve the coupling between exercise straps and support structures or people during muscular resistance training, as existing solutions are not user-friendly or secure enough to effectively provide restorative force.
Innovation Solution
The development of buckles for exercise straps that consist of a looped and hooked component, where the hooked portion nests in a recess when pivoted, providing secure coupling and adjustable restorative force through a looped exercise strap that contacts both inner faces of the components, enhancing user safety and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional coupling mechanisms are used between exercise straps and support structures, then the device complexity is reduced, but the reliability of coupling and user safety deteriorates
Solution Approach 1:
The buckle is divided into two separate components: a looped component with an aperture and a hooked component with a hooked portion. This segmentation allows each component to have a specific function while together providing secure coupling. The looped component provides the base structure and aperture for strap passage, while the hooked component provides the locking mechanism through its hooked portion that engages with the looped component.
Solution Approach 2:
The hooked portion of the hooked component nests within the looped component when coupled together. This nesting arrangement creates a compact, secure connection where the hooked portion fits inside the looped component's structure, providing reliable coupling while maintaining a space-efficient design that doesn't add excessive complexity.
2Reliability
If a secure coupling mechanism is implemented with multiple components, then the reliability of the connection improves, but the ease of operation deteriorates due to more complex assembly and adjustment
Solution Approach 1:
The hooked component is designed to be movable relative to the looped component, allowing dynamic adjustment during operation. The hooked portion can be inserted into and removed from the looped component easily, enabling users to quickly assemble and disassemble the buckle without complex tools or procedures. This dynamic design maintains connection security while significantly improving ease of operation.
3Reliability
If the exercise strap contacts only one component, then the device complexity is reduced, but the reliability of force distribution and user safety deteriorates
Solution Approach 1:
Different parts of the buckle system are designed with specific local qualities: the looped component has an aperture optimized for strap passage and positioning, while the hooked component has a hooked portion optimized for secure engagement. The exercise strap is configured to contact both components at different locations, with each contact point providing specific functional benefits. This local quality differentiation ensures reliable force distribution across multiple contact points without requiring overly complex component interactions.

AI summary
Buckles for use in exercise assemblies employing force restorative exercise straps. A looped component and a hooked component of the buckle hold the exercise strap. The looped component and the hooked component can be pivotally mounted to each other. The buckle can hold the strap in two orientations, on an end of a looped strap, or at an adjustable position of the looped strap.
