Seamless Annular Webbing Safety Appliance for Climbing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety appliances for climbing and competitive sports, with a multilayer-sewn structure, are prone to stitch failure under high-strength conditions, posing safety hazards due to wear and breakage over time.
Innovation Solution
A safety appliance featuring a seamless annular webbing with a filler wrapped inside, formed by layering tubular monolayer webbing and integrally seamless-woven with a high-strength cushioning material, eliminating joints to prevent breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a multilayer-sewn structure is used with stitches at joints, then the safety appliance can be manufactured with conventional sewing methods, but the stitches are prone to wear and break during long-term use in high-strength environments
Solution Approach 1:
The patent removes the stitching process entirely from the safety appliance construction. Instead of sewing multiple layers together with stitches that can wear and break, the invention uses a single seamless tubular webbing that encloses the filler without any joints or stitches, eliminating the reliability problem while maintaining manufacturability through seamless weaving or knitting processes
Solution Approach 2:
The patent segments the webbing structure into a tubular monolayer configuration that wraps around the filler in a continuous loop. This segmentation approach creates a seamless tube structure that avoids the need for joining multiple webbing pieces with stitches, thereby eliminating the weak points where failures occur
2Strength
If multiple webbing layers are sewn together to form a multilayer structure, then the safety appliance provides protection, but the joints and stitches become weak points that break under high-strength conditions
Solution Approach 1:
The invention extracts and eliminates the stitching joints from the structure. By using a seamless tubular webbing that encloses the filler without any sewn connections, the patent removes the weak points entirely while maintaining the protective function through the continuous seamless structure that distributes stress evenly throughout the webbing
Solution Approach 2:
The patent creates a composite structure where a seamless tubular webbing encloses a filler material, forming an integrated protective unit. This composite design combines the tensile strength of the seamless webbing with the cushioning properties of the filler, achieving both protection capability and reliability without any weak joint points
