Lateral Harness Connector Structure for Greater Movement Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional harness configurations for tree pruning limit movement amplitude and pose ergonomic and safety risks due to space-consuming attachment point assemblies and improper use issues.
Innovation Solution
A harness design featuring a belt with two lateral attachment points, each equipped with a connector comprising a closing element and body with pass-through openings and through holes, allowing for secure attachment of ropes and improved distribution of forces, enhancing movement and safety by eliminating the need for additional connectors like carabiners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional attachment point configurations are used, then the harness provides basic attachment functionality, but the assembly takes up a great deal of space which limits movement amplitude
Solution Approach 1:
The connector merges multiple functions into a single integrated component: the body provides structural support and defines the pass-through opening for the attachment element, while the closing element secures the connection ring and provides through holes for additional attachments. This consolidation eliminates the need for separate carabiners or additional connectors, reducing the overall volume of the attachment point assembly and increasing movement amplitude.
2Device complexity
If conventional attachment points are used, then the harness provides attachment capability, but it complicates the assembly and presents ergonomic problems
Solution Approach 1:
The connector is designed as a universal attachment component that can accommodate multiple types of attachments simultaneously. The body with its pass-through opening accepts the attachment element (rope, carabiner, etc.), while the closing element with through holes provides additional attachment points. This multi-functionality simplifies the overall system by replacing multiple specialized components with a single versatile connector, reducing assembly complexity and improving ergonomic usability.
3Reliability
If conventional attachment configurations are used, then the harness can be assembled, but it creates safety risks in case of improper use
Solution Approach 1:
The connector is pre-configured with the closing element that defines the connection ring and through holes in specific positions. The body is pre-formed with the pass-through opening properly sized and positioned. This preliminary configuration ensures that attachments must be made in the correct manner, reducing the risk of improper use. The structural design inherently guides proper assembly, enhancing safety while maintaining ease of operation.

AI summary
The harness includes a belt, a pair of thigh loops and first and second lateral attachment points. At least the first lateral attachment point includes a connector fixed to the belt. The connector is provided with a body defining: at least one pass-through opening inside which an attachment element to the belt passes, a connection ring distinct from the at least one pass-through opening, the connection ring being closed by means of a closing element fitted in removable manner. The closing element and the body define at least one through hole distinct from the at least one pass-through opening and from the connection ring. The closing element separate the connection ring and the at least one through hole.
