Solution Overview

Problem

Existing rope harness designs compromise ergonomics and comfort due to the shared use of a single attachment point for shoulder straps and waist belt, leading to reduced freedom of movement and increased stress on seams during suspension.

Innovation Solution

A rope harness design featuring a ventral suspension point with separate loops positioned beyond a central ring, allowing for independent movement and attachment of shoulder straps and anchor points, with strategically designed seams to indicate stress thresholds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single attachment point is used for both shoulder straps and waist belt suspension, then the device complexity is reduced, but the ergonomics and freedom of movement are degraded

Engineering Contradiction:
Improveattachment point configurationVSAvoidergonomics and freedom of movement
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent divides the attachment system into separate functional components: a first attachment point for shoulder straps and a second attachment point for waist belt suspension. This segmentation allows each attachment point to be optimized for its specific function, improving ergonomics and freedom of movement while maintaining overall system simplicity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention extracts the shoulder strap attachment function from the waist belt suspension system. By providing a dedicated first attachment point on the waist belt for shoulder straps and a separate second attachment point for suspension, the design eliminates the ergonomic conflicts caused by shared attachment points

Inventive Principle:
Principle #2Taking out (Extraction)

2Strength

If both connectors share the same buckle, then the multidirectional strength is improved, but the ergonomics of the suspension point is reduced

Engineering Contradiction:
Improvemultidirectional strengthVSAvoidergonomics of suspension point
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The patent segments the connector system into two distinct connectors: a first connector for shoulder strap attachment and a second connector for anchor point connection. Each connector operates independently at its own attachment point, eliminating the ergonomic conflicts caused by sharing a single buckle while maintaining the multidirectional strength benefits through proper geometric distribution of attachment points

Inventive Principle:
Principle #1Segmentation

3Device complexity

If the leg loops are positioned close to the waist belt attachment point, then the device complexity is reduced, but the freedom of movement between leg loops and waist belt is limited

Engineering Contradiction:
Improveloop positioning configurationVSAvoidfreedom of movement
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent positions the leg loops to extend beyond the attachment points in the longitudinal direction, creating spatial separation that allows greater freedom of movement. The leg loops are configured to pass through or beyond the attachment points, utilizing the longitudinal dimension to provide movement freedom without adding complex adjustment mechanisms

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A harness (1) comprises a waist belt (1), a first leg loop (2'), a second leg loop (2"), and a leg loop (11) connecting the first leg loop (2') and the second leg loop (2"). A ring (10) is attached to the waist belt (1) and through which the leg loop (11) passes. The ring (10) encircles the waist belt (1) and is fixed to the waist belt (1) by at least one seam. The ring (10) defines at least one first loop (5) projecting from the waist belt (1) away from the first and second leg loops (2', 2"). The leg loop (11) is fixed to the waist belt (1) beyond the ring (10) on either side of the ring (10).
