Woven Leg Connection Area for Climbing Harness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of climbing and personal protective equipment harnesses is labor-intensive due to the manual sewing of leg connection areas and roping points, which are subject to high stress and wear, leading to complexity and reduced durability.
Innovation Solution
The design features a woven leg connection area formed by loop ends of the leg loops, eliminating the need for seams and allowing for easier production, increased longevity, and improved safety through reduced friction and wear at the most stressed points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the leg connection area and roping point are made from individually sewn straps, then the harness meets safety standards, but the production process becomes labor-intensive and complex
Solution Approach 1:
The patent merges multiple individual straps into a single integrated strap structure that forms both the leg connection area and the roping point. This integration eliminates the need for separate straps and multiple sewing operations, reducing production complexity while maintaining safety through continuous material construction.
Solution Approach 2:
The integrated strap is designed with distinct functional zones: a leg connection area with first and second leg loops, and a roping point area. The strap can be segmented into these functional regions during design while remaining a single continuous piece, allowing specialized reinforcement where needed without requiring assembly of separate components.
2Duration of action of stationary object
If manual sewing is used to ensure safety and longevity, then the harness meets durability requirements, but production time and labor costs increase
Solution Approach 1:
By combining multiple straps into one integrated strap, the patent eliminates multiple sewing seams that would require manual assembly. The single continuous construction reduces production steps and labor requirements while maintaining longevity through reduced seam failure points.
Solution Approach 2:
The integrated strap design uses standard weaving or knitting processes that are more efficient and less labor-intensive than manual sewing, enabling faster production while maintaining adequate durability for the application.
3Strength
If multiple straps are sewn together to form the leg connection area, then the harness provides necessary strength, but friction and wear increase at seam locations
Solution Approach 1:
The patent eliminates seams by using a single continuous strap construction for the leg connection area and roping point. This removes the friction and wear problems associated with multiple sewn straps while maintaining structural strength through the continuous material and integrated design.
Solution Approach 2:
The strap is designed with localized reinforcement at critical areas such as the roping point and leg connection zones. The material density or structural configuration can be varied locally to provide enhanced strength where needed without requiring additional straps or seams throughout the entire structure.
