Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specific signal is input to the secondary battery and the output signal is received to identify an ID, then the secondary battery can be certified as genuine, but an incorrect signal may be mistakenly received leading to false certification
Solution Approach 1:
A magnetic field is introduced as an intermediary physical quantity between the wireless charging device and the secondary battery. The magnetic field serves as a mediator that carries identification information through its polar arrangement, enabling more reliable and precise ID identification compared to direct signal transmission alone.
Solution Approach 2:
The patent changes the parameter used for identification from electrical signal characteristics to magnetic field polar arrangement. By encoding ID information in the magnetic pole configuration (N-S pole patterns) rather than signal frequency or amplitude, the system achieves more accurate and reliable identification that is harder to spoof.
2Measurement precision
If magnetic coupling is used for identification, then accurate ID identification is achieved through precise alignment, but the device complexity increases due to magnet portion requirements
Solution Approach 1:
The magnetic field generation unit in the wireless charging device serves multiple functions: it provides the magnetic field necessary for wireless charging power transfer and simultaneously encodes identification information through its polar arrangement. This multi-functionality eliminates the need for separate identification hardware, reducing overall device complexity.
Solution Approach 2:
The patent merges the identification function with the wireless charging function by combining the magnetic field generation unit with the charging coil. The same magnetic field structure that enables power transfer also carries the ID information, consolidating multiple functions into a single integrated system.
