Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If precise positioning and alignment are required for WPT charging, then energy transfer efficiency is improved, but usability and adaptability to different vehicle types deteriorate
Solution Approach 1:
The patent applies the dynamics principle by implementing a yielding mechanism that allows the transmitting plate to dynamically adjust its position and orientation. The plate can yield and deform to accommodate misalignments between the transmitting plate and receiving plates of different vehicle types, thereby maintaining energy transfer efficiency while adapting to various vehicle dimensions and configurations.
Solution Approach 2:
The patent employs parameter changes by modifying the physical state of the transmitting plate through controlled deformation. The plate's rigidity parameter is adjusted via the yielding mechanism, allowing it to transition from a rigid fixed position to a flexible adaptive position, enabling it to compensate for positioning variations and maintain optimal coupling with different receiving plates.
2Manufacturing precision
If transmitting plates are fixed rigidly for stable power transfer, then alignment precision is improved, but adaptability to different vehicle dimensions deteriorates
Solution Approach 1:
The transmitting plate is designed with dynamic characteristics through the yielding mechanism, allowing it to adjust its position and orientation in real-time. This enables the plate to maintain precise alignment with receiving plates of various vehicle dimensions without requiring rigid fixed installation, thereby achieving both alignment precision and adaptability.
Solution Approach 2:
The patent utilizes composite material principles by combining rigid structural elements with flexible yielding components in the transmitting plate assembly. This composite structure allows the plate to maintain structural integrity for stable power transfer while incorporating flexible elements that enable adaptation to different vehicle dimensions and configurations.
3Adaptability or versatility
If a coupling standard is established for WPT charging, then standardization is improved, but flexibility for different parking configurations deteriorates
Solution Approach 1:
The patent applies universality by designing a standardized transmitting plate with a yielding mechanism that can serve multiple functions and accommodate various parking configurations. The plate can adapt to different vehicle types, dimensions, and parking orientations while maintaining a single standardized design, thereby achieving standardization without sacrificing flexibility for different configurations.

AI summary
The device object of the invention creates a coupling standard between the transmitting/receiving plate that facilitates the application of WPT charging to public charging. The device couples the receiving plate to the plate for the WPT electrical transmission and ensures the permanent desired specular and parallel correspondence and the desired inter-distance, optimal for the WPT energy transfer from the transmitting plate to the receiving plate. The device is composed of a male part and a female part. Static type WPT coupling derives from the male-female junction, at the distance and with the operating alignment required for the efficiency of the charging system, with stabilization and also inhibition of decoupling. The device is, in fact, also composed by a yielding mechanism with controlled and adjustable deformation for self-adaptation to different operating conditions, thus guaranteeing undisturbed alignment, parallelism and inter-distance between the said plates.
