Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wired communication is used between battery management apparatuses, then communication reliability is maintained, but system flexibility and scalability are limited
Solution Approach 1:
The patent replaces the mechanical wired communication system with a wireless communication system using electromagnetic induction coils. The battery management apparatus communicates with battery packs through wireless electromagnetic fields rather than physical cable connections, thereby improving system flexibility and scalability while maintaining communication functionality.
Solution Approach 2:
The patent introduces electromagnetic induction coils as an intermediary medium for communication between the battery management apparatus and battery packs. These coils enable wireless data transmission through electromagnetic coupling, serving as a mediator that replaces direct wired connections and enhances system adaptability.
2Ease of manufacture
If communication cables are connected between battery management apparatus and battery packs, then stable power and data transmission is achieved, but installation complexity increases
Solution Approach 1:
The patent eliminates the need for physical communication cables by implementing wireless electromagnetic induction communication. The battery management apparatus and battery packs exchange data and power through electromagnetic fields generated by induction coils, removing the complexity of cable routing and physical connections during installation.
Solution Approach 2:
The wireless communication system enables the battery management apparatus and battery packs to establish communication automatically through electromagnetic field coupling without requiring manual cable connection. The system self-configures the communication path through the electromagnetic medium, reducing installation effort and complexity.
3Adaptability or versatility
If wireless communication module and electromagnetic induction coils are added to battery management apparatus, then communication flexibility is improved, but device complexity increases
Solution Approach 1:
The electromagnetic induction coils serve multiple functions simultaneously: they enable wireless communication between the battery management apparatus and battery packs, and also provide power transmission. This multi-functionality reduces the need for separate components and justifies the added complexity by delivering multiple benefits from a single system.
Solution Approach 2:
The patent combines communication and power transmission functions into a single wireless electromagnetic induction system. The same induction coils used for data communication also facilitate power transfer, merging multiple functions into one integrated approach rather than requiring separate wired connections for each function.
