Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-voltage interconnection systems for movable objects, such as train cars, are bulky, lack protection against accidental contact, and have complex structures to maintain electrical connectivity during movement.
Innovation Solution
A high-voltage interconnection system utilizing a flexible cable with connection arrangements and cable holder arrangements that allow slidable movement, featuring insulated and grounded components to prevent electrical discharges and simplify the connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large post insulators or rigid terminations are used, then electrical insulation and safety are improved, but device size and structural complexity increase
Solution Approach 1:
The patent uses a flexible cable with integrated insulation instead of rigid post insulators. The cable includes a conductor, insulating layer, and optional screening layer, creating a flexible yet electrically insulated connection that adapts to movement while maintaining safety and reducing size.
Solution Approach 2:
The patent replaces rigid terminations with a flexible cable system that can dynamically adapt to relative movement between objects. The cable's flexibility allows it to bend and deform as needed, maintaining electrical connection without requiring large rigid structures.
2Stability of the object's composition
If rigid high voltage terminations are used, then electrical connection stability is improved, but adaptability to movement and ease of installation deteriorate
Solution Approach 1:
The flexible cable with its flexible conductor and insulating layer provides both stability for electrical connection and adaptability for movement. The cable can be routed through guide openings and held by cable holder arrangements, maintaining stable connection while accommodating relative motion between objects.
3Reliability
If post insulators and rigid terminations are used, then electrical insulation is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent merges the functions of post insulators, terminations, and cable management into a single flexible cable assembly. The cable includes integrated components (conductor, insulating layer, screening layer) that combine multiple functions into one element, reducing overall system complexity.
Solution Approach 2:
The flexible cable structure replaces complex rigid assemblies with a simpler flexible alternative that achieves the same electrical insulation and connection functions through its layered construction of conductor, insulating material, and screening layers.

AI summary
A high voltage interconnection system for electrically interconnecting a pair of objects that are movable relative to each other includes a flexible cable, a connection arrangement electrically contacting an end of the flexible cable, and a cable holder arrangement holding the flexible cable in a slidable manner. The cable holder arrangement may include a wear plate fixed to at least one of the objects and a sliding collar fixed on the flexible cable. The collar may be slidably supported to protect the flexible cable from damage as it moves.
