Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If wireless power transmission and communication are carried out simultaneously using the same electromagnetic field, then continuous power transmission is ensured, but electromagnetic field interference occurs between power transmission and communication signals
Solution Approach 1:
The patent divides the single electromagnetic field into two separate fields: one for power transmission and another for communication. By using distinct antenna coils (power transmission coil and communication antenna) operating at different frequencies, the system segments the electromagnetic spectrum to avoid interference while maintaining continuous power transmission and simultaneous communication
Solution Approach 2:
The patent introduces frequency separation as an intermediary mechanism to resolve the conflict between power transmission and communication. By assigning different frequency bands to power and communication signals, the system acts as a mediator that allows both functions to coexist without direct interference
2Object-affected harmful factors
If wireless power transmission and communication use separate electromagnetic fields, then electromagnetic field interference is avoided, but system complexity increases due to multiple antenna coils and control modules
Solution Approach 1:
The patent implements multi-functionality by enabling the wireless power transmission system to perform both power transfer and communication functions through integrated control modules. The first and second communication control modules can operate in different modes (first/second modes for identification, third mode for data communication), allowing a single system to handle both power and communication tasks without requiring completely separate systems
Solution Approach 2:
The patent employs dynamic mode switching where communication control modules can transition between different operating modes based on system state. The modules switch from identification modes to data communication modes dynamically, allowing flexible adaptation to different operational requirements and reducing the need for fixed, complex hardware configurations
3Adaptability or versatility
If communication control modules switch modes based on identification information, then simultaneous power transmission and communication is enabled, but additional control logic and mode switching mechanisms are required
Solution Approach 1:
The patent applies preliminary action by having communication control modules perform identification operations before switching to data communication mode. The modules first transmit and verify identification information to establish proper communication parameters, then proactively switch to the appropriate communication mode, ensuring smooth transitions without interference with power transmission
