Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for providing electrical power to heavy work machines on uneven terrain face challenges in maintaining a stable electrical connection due to terrain variations, safety risks, and the need for precise alignment, as well as the limitations of existing power rail systems in rugged environments.
Innovation Solution
A modular support structure using dielectric posts and plates to elevate power rails above ground, secured by couplers that allow for stable positioning and modular repositioning, ensuring consistent electrical connection despite terrain irregularities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If power rails are mounted near the ground for easy access, then ease of operation is improved, but safety risks increase and the system becomes vulnerable to debris damage
Solution Approach 1:
The power rails are elevated from ground level to a higher position on vertical posts, transitioning from a ground-based system to an elevated system. This dimensional change in vertical positioning simultaneously improves safety by removing rails from the debris zone and maintains accessibility through the design of engagement mechanisms at the elevated position
2Reliability
If power rails are fixed in precise positions for reliable electrical connection, then reliability is improved, but adaptability to terrain variations deteriorates
Solution Approach 1:
The system employs adjustable vertical positioning of power rails on posts and adjustable horizontal positioning through engagement mechanisms that can accommodate lateral deviations. This dynamic adjustability allows the rails to adapt to terrain variations while maintaining reliable electrical connection through compensating mechanisms
3Adaptability or versatility
If a modular support structure is used for easy repositioning, then ease of manufacture and adaptability are improved, but device complexity increases
Solution Approach 1:
The support structure is divided into modular segments including vertical posts, horizontal support members, and engagement mechanisms that can be independently assembled and disassembled. This segmentation enables easy repositioning along haul routes while managing complexity through standardized modular components

AI summary
A modular structure supports elevated rail segments for delivering electrical power to a moving work machine, such as a hauler at a mining site. Opposite ends of a roadside barrier contain complementary tubular couplers arranged vertically. A lower end of a dielectric post positioned in one of the tubular couplers has opposing dielectric plates at an upper end. A top edge of each plate has a creepage concavity between a pair of rail recesses. Another dielectric post of similar configuration is positioned in the other of the tubular couplers. Holes within the couplers and the posts ensure alignment of respective rail recesses in which conductive rails are placed. Dielectric inserts frictionally lock the rails into the rail recesses.
