Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless power receivers are used in a modular display apparatus, then power distribution capability is improved, but heat management and electromagnetic interference problems worsen
Solution Approach 1:
The display apparatus is divided into multiple independent display modules, each with its own wireless power receiver. This segmentation allows power to be distributed across multiple modules rather than concentrating power in a single location, thereby improving power distribution capability while reducing heat concentration and electromagnetic interference in any one area.
Solution Approach 2:
The system dynamically adjusts power allocation among multiple wireless power receivers based on real-time load conditions. The controller monitors power consumption of each display module and dynamically redistributes power through the wireless power transfer system, optimizing power distribution while managing heat and electromagnetic interference levels.
2Ease of operation
If a complex power supply system is used to manage multiple display modules, then power distribution control is improved, but device complexity increases
Solution Approach 1:
A single controller is designed to perform multiple functions: it manages wireless power reception, distributes power to multiple display modules, monitors power consumption, and controls voltage levels. This multi-functional controller simplifies the overall system architecture by consolidating what would otherwise require multiple separate control systems.
Solution Approach 2:
The wireless power transfer system acts as an intermediary between the power source and multiple display modules. This intermediate layer simplifies power distribution control by providing a unified interface for power management, eliminating the need for complex wired connections and multiple power supply units.
3Ease of operation
If wireless power transfer is implemented in modular display apparatus, then installation convenience is improved, but power load management becomes more difficult
Solution Approach 1:
Each display module is equipped with its own wireless power receiver that automatically manages its power reception and conversion. The modules self-regulate their power consumption and the system automatically balances power distribution, reducing the complexity of manual power load management while maintaining installation convenience.
