Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for transporting and arranging load bank cables to test UPS systems are labor-intensive, cause cable damage, create tripping hazards, and hinder effective heat dissipation and infrared scanning due to cable overlap and floor placement, particularly in narrow corridors.
Innovation Solution
A system using pushcarts with stair-like steps to support and space load bank cables in parallel, forming articulated joints, allowing for efficient transportation and arrangement without floor placement, reducing cable overlap, and facilitating heat dissipation and infrared scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If load bank cables are dragged through hallways to the UPS outlets, then the cables can be transported to the testing location, but the cable insulating cover is abraded and damaged over time
Solution Approach 1:
A cable conveyor system acts as an intermediary mechanism between the cable storage area and the UPS testing location. The system includes a cable reel, a conveyor belt, and a cable guide that work together to transport cables without direct human handling, thereby preventing abrasion of the insulating cover while maintaining ease of operation.
2Ease of operation
If load bank cables are laid on the floor during testing, then the cables are accessible for connection, but this creates tripping hazards and blocks corridors
Solution Approach 1:
The cable conveyor system elevates cable transport from the floor level to an elevated conveyor belt level. During testing, cables are fed through the cable guide from the elevated conveyor, keeping them off the floor and in organized routing paths. This dimensional change eliminates tripping hazards and corridor blockage while maintaining cable accessibility for connections.
3Manufacturing precision
If cables are arranged in parallel on the floor, then three-phase groupings can be formed to avoid eddy currents, but cable overlap occurs due to limited space and cable curling
Solution Approach 1:
The cable conveyor system with its elevated belt and guide mechanism serves as an intermediary that pre-organizes cables in parallel arrangements before they reach the testing area. The conveyor belt width and guide positioning ensure cables remain in designated positions, preventing overlap and curling. This intermediary system maintains precise three-phase groupings without requiring complex manual arrangement procedures.
4Reliability
If cables are arranged in parallel groupings, then eddy currents are avoided, but heat dissipation is interfered with and infrared scanning is hindered by cable overlap
Solution Approach 1:
The cable conveyor system provides elevated cable routing that separates cables vertically from the floor plane. The cable guide maintains proper spacing and parallel arrangement in three-dimensional space, preventing cable overlap while ensuring adequate air circulation for heat dissipation. This spatial separation allows infrared scanning equipment to access all cable surfaces without obstruction, while maintaining the parallel grouping configuration that prevents eddy currents.

AI summary
Both a system and method for transporting and arranging a plurality of load bank cables to test an uninterruptible power supply (UPS) are provided. The system includes a plurality of cables configured to be electrically connected between an uninterruptible power supply and a load bank, and a cable conveying assembly including a plurality of pushcarts and configured to support the plurality of cables parallel to one another. Each pushcart is further configured to support the parallel cables in a spaced-apart relationship both horizontally and vertically. The cables are loaded onto the pushcarts such that portions of the plurality of cables disposed between the pushcarts form articulated joints in the cable conveying assembly. The UPS is tested while the cables are supported by the pushcarts.
