Webbing Guide With Elastic Claw For Secure Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing webbing guides are difficult to assemble and prone to detachment from the member for assembly, as ease of assembly often compromises the stability and retention of the guide.
Innovation Solution
A webbing guide design featuring a tubular guide body with front and rear restriction parts, a claw, and a connection part with a concave surface, allowing for easy assembly while inhibiting detachment through a combination of contact points and structural alignment, including multiple rear walls for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the webbing guide is designed with a simple structure for easy assembly, then ease of assembly is improved, but the guide becomes prone to detachment from the member for assembly
Solution Approach 1:
The webbing guide is divided into multiple functional components: front restriction parts for easy insertion, rear restriction parts for positioning, and a claw with elastic deformation capability for secure retention. This segmentation allows each part to specialize in either ease of assembly or prevention of detachment
Solution Approach 2:
The claw is designed to elastically deform during the assembly process - bending to pass through the opening and then recovering its shape to engage with the member for assembly. This dynamic behavior enables the claw to transition from a flexible insertion state to a rigid retention state, resolving the contradiction between ease of assembly and retention stability
2Ease of operation
If the claw is shortened to facilitate passage through the opening, then ease of assembly is improved, but the detachment resistance is reduced
Solution Approach 1:
The claw maintains its full length to ensure adequate detachment resistance, but utilizes elastic deformation to temporarily reduce its effective size during insertion. The claw bends elastically to pass through the opening and then recovers, maintaining both ease of assembly and strength
Solution Approach 2:
The physical state of the claw changes during assembly - transitioning from a rigid structure to an elastically deformed state during insertion, then returning to rigid form for retention. This parameter change allows the claw to be both insertable and strong

AI summary
Webbing guide includes: guide body through which webbing is inserted; front wall that contacts one side face of first opening edge part and second opening edge part; rear wall that contacts another side face of first opening edge part; and claw that contacts another side face of second opening edge part. Connection part connects guide body and rear wall and includes concave part, and leading end of first opening edge part enters into concave part when webbing guide is assembled with member for assembly.
