Stud-to-Tie Strap Fastener With Pivot Clamp for Easy Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fasteners used to connect threaded studs and tie straps are difficult to remove and often damage when attempting to reposition wires or fluid lines in vehicles, leading to the need for a reusable and easily removable fastener solution.
Innovation Solution
A fastener design featuring a body and clamp that pivot relative to each other, with snapable engagement and release mechanisms, allowing for quick assembly and disassembly without damaging the fastener or tie strap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If internal barbs are used to retain the fastener on the threaded stud, then the fastener can be securely connected, but the fastener becomes difficult to remove and may be damaged during removal attempts
Solution Approach 1:
The fastener employs a resilient arm that can dynamically change its state between engaged and disengaged positions. The resilient arm is biased to engage with the threaded stud during installation, providing secure connection. During removal, the resilient arm can be deliberately disengaged from the threaded stud, allowing easy removal without damage. This dynamic state change resolves the contradiction between secure connection and easy removal.
2Reliability
If the fastener is designed for secure retention on the threaded stud, then the connection is reliable, but the tie strap and fastener must be replaced instead of being reused
Solution Approach 1:
The fastener design enables recovery and reuse of both the fastener and tie strap. The resilient arm can be deliberately disengaged from the threaded stud, and the clamp can be opened to release the tie strap, allowing all components to be recovered and reused. This eliminates the need to discard and replace components after a single use, resolving the contradiction between reliable connection and reusability.
3Productivity
If the fastener uses a resilient arm with internal barbs for engagement, then the fastener can be quickly assembled, but the removal process damages the fastener requiring replacement
Solution Approach 1:
The resilient arm provides quick assembly through automatic engagement with the threaded stud. For removal, the resilient arm can be deliberately disengaged, enabling easy removal without damage. This dynamic design maintains high assembly speed while eliminating damage during removal, resolving the contradiction between assembly productivity and removal ease.
