Continuous Lineman Loop Harness Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing harness devices for tree climbing concentrate force on the edges, reducing comfort and safety by not effectively distributing the user's weight, leading to potential injuries during falls.
Innovation Solution
A saddle with continuous lineman's loops attached to upper and lower straps, distributing weight across a larger area, enhancing strength, safety, and comfort by using a continuous loop of webbing that engages a lineman's rope for secure anchoring to a tree.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional lineman's loops are used (pair of loops at edge of harness), then the structure is simple, but the force is concentrated on edges reducing comfort and safety
Solution Approach 1:
The continuous loop is divided into multiple functional segments: upper portion attached to upper strap, lower portion attached to lower strap, and lateral portions forming the actual loops. This segmentation allows force to be distributed across multiple attachment points rather than concentrated at edges, resolving the contradiction between strength and structural simplicity.
Solution Approach 2:
The invention transitions from a two-loop edge configuration to a continuous loop extending across the harness in multiple dimensions. The continuous loop wraps around the harness body, distributing force across upper and lower straps and lateral portions, effectively adding dimensional complexity to achieve better force distribution.
2Reliability
If continuous loop design is used, then weight is distributed across larger area improving comfort and safety, but the device structure becomes more complex
Solution Approach 1:
The continuous loop merges multiple functions into a single integrated structure: it provides attachment points for lineman's rope, distributes weight across upper and lower straps, and creates lateral portions for additional anchoring. This merging achieves improved reliability while the integrated design prevents excessive complexity.
Solution Approach 2:
The continuous loop serves multiple functions simultaneously: it acts as a weight distribution system, provides multiple attachment points for the lineman's rope, and creates lateral portions for additional security. This multi-functionality justifies the structural complexity by delivering comprehensive safety improvements.
3Ease of operation
If force is concentrated on harness edges, then the loop structure is simple, but comfort and safety are reduced
Solution Approach 1:
The continuous loop creates different local qualities across the harness structure: upper and lower straps provide vertical support, while lateral portions provide horizontal distribution. This local differentiation optimizes comfort in each region while the overall structure remains manageable, resolving the contradiction between comfort and complexity.

AI summary
A harness with continuous lineman's loop includes a saddle having an upper strap and a lower strap. The saddle has a front side, a back side, a first lateral edge and a second lateral edge wherein the first and second lateral edges are used to engage a bridge line such that the bridge line can be secured to a tree. A pair of lineman's loops is attached to the saddle and used to engage a lineman's rope. Each of the lineman's loops is positioned adjacent to one of the first and second lateral edges. The lineman's loops are comprised of a continuous loop of webbing including an upper portion is attached to the upper strap and a lower portion is attached to the lower strap. The lineman's loops are formed of lateral portions of the continuous loop extending between the upper and lower portions.
