Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inductively powered vehicles require a battery for movement when deviating from the primary conductor's path, as energy consumption is reduced or interrupted by such deviations, necessitating a solution for continuous energy absorption without an energy store.
Innovation Solution
A primary conductor system with a meandering current loop and secondary windings arranged in a triangular lattice structure, where pairs of secondary windings are inductively coupled, allowing for continuous energy absorption by optimizing the alignment and spacing of pick-ups to maintain energy transfer across different orientations and positions relative to the primary conductor.

Engineering Contradiction Analysis
1Reliability
If a single pair of secondary windings is used for inductive power transmission, then the structure is simple, but continuous energy absorption cannot be maintained when the vehicle deviates from the primary conductor path
Solution Approach 1:
The secondary winding arrangement is segmented into multiple pairs (at least two pairs with perpendicular connecting lines, or three pairs with 60° angles). Each pair can independently absorb energy when positioned correctly relative to the meandering primary conductor, ensuring continuous power supply regardless of vehicle position or orientation.
Solution Approach 2:
The solution transitions from a single linear arrangement to a two-dimensional lattice structure with multiple pairs oriented at different angles (90° or 60°). This dimensional expansion allows the system to capture energy from the meandering conductor regardless of the vehicle's orientation or position on the surface.
2Area of stationary object
If the distance between secondary windings is reduced to maximize energy absorption, then installation space is minimized, but the vehicle orientation sensitivity increases
Solution Approach 1:
The secondary windings are arranged in asymmetric patterns relative to each other (perpendicular or 60° angles) rather than identical parallel positions. This asymmetric multi-orientation arrangement ensures that at least one pair will be optimally positioned to absorb energy regardless of the vehicle's rotation or the conductor's meander pattern.
