Serviceable Stud-to-Tie Strap Fastener for Reusable 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 quick assembly, easy removability, and reusability.
Innovation Solution
A fastener design featuring a pivotably connected body and clamp that snapably secures onto a stud, allowing for easy assembly and disassembly without damage, utilizing toothed resilient arms to engage and disengage from the stud threads, and incorporating a tie strap loop for securement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If internal barbs are used to retain the fastener on the threaded stud, then the fastener is securely held in place, but the fastener becomes difficult to remove and may be damaged when attempting to reposition
Solution Approach 1:
The fastener incorporates 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 normal operation, providing secure retention. When removal is needed, the resilient arm can be deliberately disengaged from the threads, allowing easy removal without damage. This dynamic capability resolves the contradiction between secure retention and ease of removal.
2Reliability
If the fastener is designed for secure retention on the stud, then reliability is improved, but the fastener cannot be easily repositioned for servicing wires and fluid lines
Solution Approach 1:
The resilient arm provides dynamic engagement capability, allowing the fastener to be securely attached to the threaded stud during normal operation for stable connection. When repositioning is required for servicing, the resilient arm can be deliberately disengaged from the threads, enabling the fastener to be moved to a different location. This dynamic design simultaneously achieves connection stability and repositionability.
3Strength
If traditional fasteners are used that are difficult to remove, then assembly strength is maintained, but time is lost during servicing operations and components may be damaged
Solution Approach 1:
The resilient arm is designed to provide strong engagement with the threaded stud during normal operation, maintaining assembly strength. However, when servicing is needed, the resilient arm can be quickly disengaged from the threads through simple manipulation, dramatically reducing servicing time compared to traditional fasteners that require cutting or prying. This eliminates the time loss while maintaining strength during operation.
Solution Approach 2:
The resilient arm design allows the fastener to be easily manipulated into engaged and disengaged states without requiring special tools or complex procedures. The operator can service the fastener by simply pressing or pulling the resilient arm, making the fastener self-serviceable and eliminating the need for damaging removal methods.
