Load Bar for Harness Adapter Absorbing Compressive Forces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current harness adapter systems face limitations in carrying heavier loads, leading to compressive forces that cause discomfort for linemen, even when loads are below the 500 lbs. safety limit, necessitating a solution to distribute weight more effectively and prevent compression.
Innovation Solution
The introduction of a load bar within the harness adapter system, which includes an outer and inner pipe structure with coaxially aligned holes and a locking pin, allowing the load bar to absorb compressive forces instead of the lineman, and can be adjusted or fixed in length to accommodate various applications and lineman sizes, increasing the load weight limit to 2000 lbs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the harness adapter system is used to carry heavier loads, then the load weight limit is increased, but compressive forces are exerted on the lineman causing discomfort
Solution Approach 1:
The patent introduces a load bar as an intermediary component between the harness adapter system and the load. This load bar acts as a mediator that absorbs and distributes the compressive forces generated by heavy loads, preventing these forces from being directly transmitted to the lineman's body. The load bar serves as a mechanical buffer that decouples the load bearing function from the lineman support function.
2Adaptability or versatility
If the harness adapter system supports weights up to 500 lbs., then it meets safety limits, but it cannot accommodate applications requiring heavier loads
Solution Approach 1:
The patent implements an adjustable load bar mechanism that can be dynamically configured to different lengths and positions. This dynamic adjustability allows the system to adapt to various load weights and lineman sizes, optimizing the compression prevention geometry for each specific application scenario. The adjustable nature enables the system to maintain effectiveness across a broader range of operating conditions.
3Ease of operation
If a load bar is added to prevent compression, then comfort is improved, but device complexity increases
Solution Approach 1:
The patent divides the harness adapter system into distinct functional modules: the original harness adapter components and the separate, attachable load bar component. This segmentation allows the compression prevention function to be added as an independent module that can be easily attached or removed without redesigning the entire system. The load bar functions as a standalone component with simple attachment mechanisms.

AI summary
A load bar having a straight pipe body disposed between two opposite end sections, wherein the pipe body has a radial cross section; and two end loops, each end loop having a radial cross section and being disposed on a different end section of the load bar, wherein the radial cross sections of the two end loops are parallel with each other and perpendicular to the radial cross section of the pipe body. The load bar may be implemented within the harness adapter connector portion of a harness adapter system in order to prevent the compressive force from an attached load from being exerted on a secured lineman. Utilization of this load bar may increase the safe load limit while securing a lineman from 500 lbs. to 2000 lbs., effectively broadening the application for the harness adapter system. The load bar may also be used with lighter loads to prevent lineman discomfort.
