Roping Harness With Integrated Elastic Wire for Low-Bulk Ascension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roping harnesses for acrobatic activities are bulky and inefficient for ascending operations, leading to user fatigue, and existing solutions for improving efficiency result in additional bulk when not in use.
Innovation Solution
A roping harness design featuring a belt with a lining, leg loops, and an elastic wire element that moves relative to the belt through channels in the lining, allowing seamless integration and storage of the ascension system, with a sheath providing additional support and reduced friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a flexible strap connects the left clamp to the upper body to bias the clamp upwards, then rope ascension efficiency is improved, but the system becomes bulky when not in use
Solution Approach 1:
The patent merges the ascension system components (elastic wire element, sheath, connectors) directly into the belt structure. The elastic wire element is integrated within the belt's lining, and the sheath is incorporated as part of the belt assembly, eliminating the need for separate flexible straps and reducing overall system bulk while maintaining ascension functionality.
Solution Approach 2:
The belt is designed to serve multiple functions: it provides structural support, houses the elastic wire element for ascension, contains the sheath for smooth operation, and integrates connectors for rope clamp attachment. This multi-functionality eliminates the need for separate dedicated ascension straps, reducing system bulk while improving efficiency.
2Stability of the object's composition
If a rigid mechanical connection exists between foot clamps connected to the upper body, then structural stability is improved, but the system becomes bulky when not in use
Solution Approach 1:
The patent combines the rigid mechanical connection features directly into the belt structure. The outer wall provides structural rigidity, while the integrated sheath and elastic wire element maintain stability during ascension operations. This integration eliminates the need for separate rigid connection assemblies, reducing system bulk while preserving structural stability.
3Ease of operation
If the elastic wire element is installed in a sheath attached to the belt top, then ease of handling is improved, but belt wear increases
Solution Approach 1:
The patent nests the sheath within the belt's lining structure, with the elastic wire element nested within the sheath. This nested arrangement protects the elastic wire element for smooth movement while the sheath is protected by the lining, distributing wear across multiple layers and preventing direct wear on the belt itself, thereby improving reliability.
Solution Approach 2:
The sheath acts as an intermediary between the elastic wire element and the belt lining. It provides a smooth surface for the elastic wire element to slide against, reducing friction and wear on both the wire element and the belt lining, thereby improving ease of handling while enhancing reliability by reducing wear.

Function Achieved in This Case
The design enhances user-friendliness and integrates the ascension system better, reducing bulk and wear, while maintaining efficient operation and ease of use during both ascending and descending movements.

AI summary
A roping harness includes a belt, a pair of leg loops and an elastic wire element. The belt has a lining arranged between an outer wall and an inner wall. The elastic wire element is securedly attached to the belt and has one end arranged movably with respect to the belt by elastic deformation. The lining defines a channel receiving a part of the elastic wire element. The outer wall defines a right through hole or a left through hole opening out facing the channel. The elastic wire element passes through the two through holes so that the end of the elastic wire element is located outside the channel.
