Pivot Bracket Safety Release Mechanism for Sports Straps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports equipment attachment mechanisms are not simple and reliable enough, particularly in terms of triggering safety, as they often require complex designs and may not provide consistent tripping forces when releasing under excessive tension.
Innovation Solution
A device featuring a triggering mechanism with an engagement element and a securing element, where the securing element is fixed via a spring mechanism, allowing the engagement element to pivot between engagement and release positions, and adjustable via a spring travel mechanism to define the tripping force, ensuring reliable and customizable safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex release mechanism is used to ensure safety, then reliability is improved, but device complexity increases
Solution Approach 1:
The release mechanism is divided into distinct functional components: a bracket element with pivot axis for movement, a securing element for locking, and a spring mechanism for providing force. This segmentation allows each component to perform its specific function reliably while keeping the overall design manageable and not excessively complex.
2Reliability
If a fixed trigger force mechanism is used, then reliability is improved, but adaptability decreases
Solution Approach 1:
The mechanism transitions from a static fixed-force design to a dynamic adjustable design. The spring mechanism can be preloaded to different extents, and the pivot axis position can be adjusted, allowing the trigger force to be dynamically adapted to different applications while maintaining consistent operation during each release event.
Solution Approach 2:
The physical parameters of the mechanism, specifically the spring preload force and the pivot axis position, can be changed to adjust the trigger force. This allows the same basic mechanism to be adapted for different weight limits and safety requirements without redesigning the entire system.
3Device complexity
If a simple release mechanism is used, then device complexity is reduced, but reliability decreases
Solution Approach 1:
The mechanism is designed to be self-actuating through the spring mechanism that automatically provides the necessary force for release when the trigger point is reached. The bracket element pivots automatically when the engagement element experiences excessive tension, eliminating the need for complex external actuation systems while maintaining reliable safety function.

Implementation Method 1
one of the two elements, the bracket element, is fixed to the fastening part via a spring mechanism such that the distance between the pivot axis of the bracket element and the securing element changes when a tensile load is applied to the bracket element
