Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different charging pads are provided in two directions of traffic for various vehicle lengths, then compatibility with different vehicle lengths is improved, but the length and complexity of charging infrastructure increases
Solution Approach 1:
The patent applies asymmetry by positioning both stationary capture elements symmetrically on the vehicle but designing the charging pad layout asymmetrically relative to the vehicle direction. The charging pads are arranged such that they can serve both directions of traffic without requiring symmetric duplication, thereby reducing infrastructure length while maintaining adaptability to different vehicle lengths (30m and 40m).
Solution Approach 2:
The charging infrastructure is designed with multi-functionality where a single set of charging pads serves multiple purposes: accommodating different vehicle lengths (30m and 40m), supporting both directions of traffic, and providing operational redundancy. This universal design eliminates the need for separate charging pads for each scenario, reducing overall infrastructure length.
2Adaptability or versatility
If different charging pads are provided in two directions of traffic, then compatibility with different vehicle lengths is improved, but device complexity increases
Solution Approach 1:
The patent merges the functionality of multiple charging pads into a single integrated charging infrastructure. By combining the charging capabilities for both directions of traffic and different vehicle lengths into one unified system with symmetric capture elements, the design reduces device complexity while maintaining adaptability. The symmetric arrangement allows the same charging pad configuration to serve multiple purposes.
3Length of stationary object
If single charging pad is used, then infrastructure length is reduced, but operational redundancy is lost in case of failure
Solution Approach 1:
The charging infrastructure is segmented into multiple independent charging pads that can operate autonomously. This segmentation allows the system to maintain operational redundancy - if one pad fails, others can continue servicing vehicles. The symmetric capture elements are positioned to work with individual pads, enabling selective use of functional pads while reducing overall infrastructure length compared to traditional redundant designs.
4Reliability
If symmetric capture elements are arranged for both directions, then operational redundancy is improved, but the number of capture elements increases
Solution Approach 1:
Instead of placing capture elements on the ground and having vehicles pass over them, the patent inverts the arrangement by mounting capture elements on the vehicle itself. This allows the same symmetric capture elements to cooperate with charging pads regardless of vehicle direction, providing operational redundancy without increasing the number of capture elements. The inversion enables one set of elements to serve multiple functions.
