Webbing End Cap Assembly with Locking Slider
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing end caps for webbing often fail to prevent fraying effectively, may be heavy, or lack aesthetic appeal, limiting their utility and functionality.
Innovation Solution
An end cap assembly comprising an end closure with spaced apart arms and a slider that can be locked into place, featuring a locking element and gripping elements to securely hold the strap's distal end, preventing fraying and allowing for adjustable length without moving during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional end caps are used to prevent fraying, then fraying is prevented, but the end caps may move during use and lack aesthetic appeal
Solution Approach 1:
The end cap assembly is divided into two main segments: an end closure that covers the webbing end to prevent fraying, and a separate slider that locks the assembly in place. This segmentation allows each component to perform its specific function optimally - the end closure prevents fraying while the slider provides stability, resolving the contradiction between fraying prevention and stability.
Solution Approach 2:
The end closure is inserted through the webbing, and the slider is then placed over the end closure, creating a nested structure. The end closure sits within the slider assembly, with the slider's arms enclosing the end closure. This nesting ensures the end closure remains securely positioned and prevents it from moving during use, while maintaining its fraying prevention function.
2Adaptability or versatility
If adjustable length is allowed, then versatility is improved, but the end cap may move during use
Solution Approach 1:
The slider is designed to be movable along the webbing during the adjustment phase, allowing the user to slide it to the desired position. Once positioned, the slider engages with the end closure to lock the assembly in place. This dynamic design enables length adjustment while ensuring stability during use, as the locked position prevents any movement of the end cap assembly.
3Reliability
If the end closure covers the webbing end, then fraying is prevented, but the device complexity increases
Solution Approach 1:
The end closure serves multiple functions: it covers the webbing end to prevent fraying, provides a surface for the slider to engage with, and acts as a connector between the webbing and the slider. This multi-functionality reduces the need for additional components, thereby limiting the increase in device complexity while maintaining effective fraying prevention.

AI summary
An end cap assembly for a strap is provided. The end cap assembly includes an end closure and slider. The end closure has a base, a pair of spaced apart arms extending from the base, and a locking element connected to at least one of the pair of spaced apart arms. The base and pair of spaced apart arms define a holder for receiving the strap. The slider has a body defining a cavity from a first to a second end of the body, the cavity sized to receive the strap. The slider is moveable between an unlocked and a locked position. In the unlocked position, the slider body is slideable along a length of the strap. In the locked position, a first end of the slider is adjacent to the base of the end closure and the locking element of the end closure is engaged with the slider.
