Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single wireless charger is used, then the device structure is simple, but only one mobile terminal can be charged at a time
Solution Approach 1:
The wireless charger is divided into multiple independent power converter modules (first power converter, second power converter, etc.), each capable of charging one mobile terminal. This segmentation allows multiple terminals to be charged simultaneously while keeping each module's structure relatively simple and manageable.
Solution Approach 2:
Each power converter module is designed with universal functionality to charge different types of mobile terminals (smartphones, laptops, tablets). The modules can independently handle different power requirements and device types, making the overall system capable of serving multiple purposes simultaneously.
2Ease of operation
If multiple separate charging devices are used for different terminals, then each device can be optimized for specific terminals, but the user experiences inconvenience of managing multiple devices
Solution Approach 1:
Multiple power converter modules are merged into a single integrated wireless charger system. This combination allows users to charge multiple different mobile terminals simultaneously using one device, eliminating the need to manage multiple separate chargers while maintaining the ability to handle various device types.
3Productivity
If power is supplied to multiple terminals simultaneously, then charging efficiency increases, but power distribution and control becomes more complex
Solution Approach 1:
The power management system is segmented into independent power converter modules, each handling power conversion for specific terminals. This modular approach distributes the complexity across multiple independent units rather than requiring one complex centralized control system, making power distribution more manageable.
Solution Approach 2:
Each power converter module operates with a degree of autonomy, managing its own power conversion and delivery to connected terminals. This self-service capability reduces the burden on centralized control and simplifies the overall power management architecture by distributing intelligence across modules.
