Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless power feeding is implemented without direct power cables, then ease of installation and device placement flexibility are improved, but the complexity of the power supply system increases
Solution Approach 1:
The wireless power feeder is nested within the indoor air conditioner unit, utilizing the existing air conditioner housing and power supply infrastructure. This allows the wireless power transmission device to be installed without requiring separate mounting locations or additional external power connections, thereby improving installation ease while managing system complexity through integrated design
Solution Approach 2:
The indoor air conditioner is designed to serve dual functions: traditional air conditioning and wireless power transmission. By integrating the wireless power feeder into the air conditioner, the system can power multiple devices (sensors, cameras, controllers) wirelessly within the monitored space, eliminating the need for separate power infrastructure and reducing overall system complexity
2Adaptability or versatility
If wireless power transmission is used, then device placement flexibility is improved, but power transmission safety and human exposure control become more complex
Solution Approach 1:
The control board continuously monitors the operational status and adjusts the wireless power transmission parameters accordingly. The system detects the presence and number of persons in the space, and based on this feedback, dynamically controls the radio wave transmission intensity to minimize human exposure while maintaining adequate power delivery to devices, thus managing safety complexity
Solution Approach 2:
The radio wave transmission intensity is made dynamic rather than static. The control board adjusts the transmission power level based on real-time conditions including the number of persons present and their positions. This dynamic adjustment allows the system to maintain device placement flexibility while adapting to safety requirements, reducing radio wave impact on humans when necessary
3Adaptability or versatility
If multiple devices are powered wirelessly in the same space, then system versatility is improved, but power supply management complexity increases
Solution Approach 1:
Each device powered by the wireless power feeder operates independently within the shared power transmission environment. The control board manages power distribution by controlling the overall transmission parameters, allowing multiple devices to receive power simultaneously without requiring complex individual power management for each device, thus maintaining system versatility while managing power supply complexity
