Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless charging equipment only provides battery charging function, then the system is simple and reliable, but additional services and information transmission cannot be provided
Solution Approach 1:
The wireless charging equipment is designed to perform multiple functions: it can provide battery charging services, transmit additional information through BLE broadcasting, and communicate with terminals using both magnetic resonance wireless charging and Bluetooth Low Energy protocols. This multi-functionality allows the system to serve diverse purposes without requiring separate dedicated devices.
Solution Approach 2:
Bluetooth Low Energy (BLE) is introduced as an intermediary communication channel between the wireless charging equipment and terminals. The BLE module enables additional information transmission and service communication without interfering with the primary magnetic resonance wireless charging function, effectively mediating between the charging system and auxiliary services.
2Productivity
If wireless charging equipment transmits charging signal continuously, then charging efficiency is high, but power consumption increases and heat generation occurs
Solution Approach 1:
The wireless charging equipment transmits charging signals in periodic time slots rather than continuously. During designated time slots, the equipment transmits charging signals to terminals, while in other time slots, it transmits additional information through BLE broadcasting. This periodic operation pattern maintains charging efficiency while reducing overall power consumption and heat generation by allowing the system to rest between transmission cycles.
3Adaptability or versatility
If wireless charging equipment transmits additional information through BLE, then service functionality is enhanced, but transmission time is limited by charging time slots
Solution Approach 1:
The system divides time into periodic slots, with specific slots allocated for BLE information transmission and others for magnetic resonance charging. This periodic scheduling ensures that additional information can be transmitted regularly without compromising charging efficiency, as both functions operate in designated time windows rather than competing for the same time resources.
Solution Approach 2:
The wireless charging equipment dynamically adjusts its operation mode based on the current time slot. It switches between magnetic resonance charging mode and BLE broadcasting mode according to the periodic schedule, optimizing resource utilization and ensuring both charging and information transmission functions are performed effectively within their respective time allocations.
4Productivity
If power is divided into multiple channels for different terminal classes, then power allocation efficiency is improved, but channel management complexity increases
Solution Approach 1:
The wireless charging equipment divides its total power output into multiple channels, with each channel configured for specific terminal classes based on their power requirements. Different channels have different power characteristics tailored to specific device types, allowing efficient power delivery optimized for each terminal class while maintaining manageable complexity through structured channel organization.
