Solution Overview

Problem

Existing climbing harnesses with connectors hinder efficient use of rope progression and safety accessories due to the complexity of switching between devices, leading to difficulties in rope movements and interference from non-used accessories.

Innovation Solution

A harness with a connector system featuring a first openable ring and a second fixed ring, where the second ring is non-openable and formed by a closure element, allowing for better distribution of forces and easier attachment of rope blockers or lanyards, with anti-rotation means to prevent screw stress and facilitate secure attachment points.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple rope progression accessories are mounted on the connector, then the climber can quickly switch between devices, but the rope movements are hindered by accessories not in use and the rope lock interferes with the descender functioning

Engineering Contradiction:
Improveability to switch between progression accessoriesVSAvoidrope movement smoothness
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The connector is divided into two separate rings: a first ring for mounting progression accessories and a second ring for rope passage. This segmentation allows the rope to move freely through the second ring while accessories are mounted on the first ring, eliminating interference between rope movement and mounted devices.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first ring acts as an intermediary structure between the connector body and the rope. Accessories are mounted on the first ring, which can rotate independently, allowing the rope to pass through the second ring without being blocked by accessories mounted on the first ring.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If a single ring connector is used to attach progression accessories, then the structure is simple, but the force distribution is concentrated and the attachment points are limited

Engineering Contradiction:
Improveconnector structure simplicityVSAvoidforce distribution
Core Design Contradiction:
Device complexityVSForce

Solution Approach 1:

The single ring is segmented into two distinct rings with different functions. The first ring serves as a mounting platform for accessories while the second ring handles rope passage, distributing forces across two separate structures rather than concentrating all forces on a single ring.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The two rings are arranged in different spatial orientations, creating a three-dimensional force distribution system. This allows forces to be distributed across multiple attachment points and directions, improving overall force management while maintaining structural simplicity.

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

3Ease of operation

If the connector uses a removable rod fixed by screw to open the ring, then the ring can be opened for accessory attachment, but the screw creates rotation stress and the opening mechanism is complex

Engineering Contradiction:
Improvering openabilityVSAvoidopening mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Instead of using a screw to open the ring, the design uses a push-button mechanism that releases a locking element. The button is pushed to release the lock, allowing the ring to open, and springs automatically return the button to its locked position when released, inverting the traditional screw-operated opening mechanism.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The push-button mechanism incorporates springs that automatically return the button to its locked position after opening. This self-returning mechanism eliminates the need for complex manual operation to close and lock the ring, reducing operational complexity while maintaining ease of opening.

Inventive Principle:
Principle #25Self-service

AI summary

The invention relates to a harness (1) comprising a belt (2) and leg loops (3) connected by a connector (4) forming a ventral suspension point. The connector (4) defines two separate rings (20, 30). The first ring (20) is openable and connects the belt (2) to the leg loops (3). The two rings (20, 30) are fixed one above the other. The first ring (20) and the second ring (30) have, respectively, a first median longitudinal plane and a second median longitudinal plane, the first median longitudinal plane being perpendicular to the second median longitudinal plane. The connector (4) comprises a body (5) and a fastening element (6) removably mounted relative to the body (5) to form the first ring (20). At least one fastening screw (7) secures the fastening element (6) to the body (5).
