Webbing Bridge Buckle Attachment for Replaceable Safety Harnesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing webbing bridges in climbing and personal protective equipment are difficult and unsafe to replace, with manual knotting or screwing processes that can lead to improper connections and increased wear, compromising safety.
Innovation Solution
A webbing bridge design featuring a frame buckle and web buckle at its ends, where the web buckle is guided through an eyelet and then the frame buckle, allowing for secure clamping and easy attachment and detachment, reducing the risk of loosening and wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If webbing bridges are connected using manual knotting or screwing methods, then the connection can be established, but the replacement process becomes laborious and safety is compromised due to improper connections
Solution Approach 1:
The patent introduces an intermediary attachment mechanism consisting of a clamping element and a counter-clamping element that mediate between the webbing bridge end and the belt loop. This mechanical intermediary system replaces manual knotting or screwing operations, providing both ease of operation (simple insertion and release) and high reliability (positive mechanical engagement with friction locking), thereby resolving the contradiction between ease of replacement and connection safety.
2Adaptability or versatility
If the webbing bridge is made replaceable by users, then maintenance flexibility is improved, but improper installation and insufficient tightening lead to safety issues
Solution Approach 1:
The attachment mechanism is designed to be self-servicing for the user - the clamping element can be easily inserted through the belt loop and engaged with the counter-clamping element without requiring specialized tools or skills. The system automatically ensures proper engagement through its mechanical design (friction locking, positive engagement), eliminating the need for users to perform complex tightening operations while maintaining high connection security.
3Device complexity
If traditional eyelet connections are used for webbing bridges, then the structure is simple, but increased wear results in frequent replacement requirements
Solution Approach 1:
The patent utilizes flexible webbing material with integrated clamping elements that distribute mechanical stresses over larger surface areas compared to traditional rigid eyelet connections. The flexible nature of the webbing and the distributed contact areas reduce point loads and friction concentrations, thereby minimizing wear on both the webbing bridge and the belt loop while extending service life, all while maintaining relatively simple device structure.
