Roping Harness Adjustment Device with Integrated Elastic Wire
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roping harnesses for acrobatic activities are cumbersome and inefficient during rope ascent and descent operations, with issues related to space management, wear, and interference between ascenders or blockers.
Innovation Solution
A roping harness design featuring a belt with an inner and outer wall, incorporating a pair of leg loops and at least one elastic wire element that moves relative to the belt through dedicated through holes and channels, allowing seamless integration and storage of the ascender system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an elastic wire element is used to connect the rope ascender to the belt, then the rope ascent system can be integrated into the harness, but the elastic wire element causes accelerated wear of the belt
Solution Approach 1:
The patent divides the belt structure into separate functional components: an outer wall and a lining, with the elastic wire element confined to a dedicated channel in the lining. This segmentation isolates the wear-causing elastic element from direct contact with the belt's outer surface, preventing accelerated wear while maintaining integration functionality.
Solution Approach 2:
The patent introduces a sheath as an intermediary component between the elastic wire element and the belt structure. The sheath is received within the channel and provides a protective interface, preventing the elastic wire from directly wearing the belt while still allowing the necessary mechanical connection and movement.
2Ease of operation
If the elastic wire element is mounted movable relative to the belt, then the rope ascender can be positioned during ascent operations, but the elastic wire element occupies space within the harness
Solution Approach 1:
The patent nests the elastic wire element within a dedicated channel formed in the lining of the belt. The channel is sized to receive the elastic wire element, allowing it to move freely during operation while being contained within the belt's structure. This nesting approach minimizes the space occupied by the movable element while maintaining its functional mobility.
3Reliability
If a sheath is added to protect the elastic wire element, then wear of the belt is reduced, but the construction becomes more complex
Solution Approach 1:
The patent merges the sheath protection function with the existing channel structure in the lining. Rather than adding a separate protective component, the channel itself serves as the protective enclosure for the elastic wire element. This combining approach reduces construction complexity while maintaining wear protection benefits.

Function Achieved in This Case
The design enhances ease of use and integration of the rope ascent system, reducing bulk and wear, while providing efficient and ergonomic movement during ascent and descent.
Implementation Method 1

AI summary
A roping harness (1) comprises a belt (2), a pair of leg loops (3) and an elastic wire element (4). The belt has a lining (2b) arranged between an outer wall (2c) and an inner wall (2a). The elastic wire element (4) is integral with the belt (2) and has one end mounted so as to be movable relative to the belt (2) by elastic deformation. The lining (2b) defines a channel (6) receiving a portion of the elastic wire element (4). The outer wall (2c) defines a right through hole (5a) or a left through hole (5b) opening opposite the channel (6). The elastic wire element (4) passes through the two through holes (5a, 5b) so that the end of the elastic wire element (4) is arranged outside the channel (6).
