Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual control panels or remote controllers are used for fan operation, then the fan can be turned on and off and regulated, but the intelligence degree is limited and requires user intervention
Solution Approach 1:
The fan driving device automatically senses human activity through the microwave sensing module and adjusts fan operation without user intervention. The sensing unit periodically detects whether any human activity exists within the action range and the processing unit autonomously controls turn-on, turn-off, and power regulation based on detected signals, making the system self-sufficient.
Solution Approach 2:
The patent replaces manual mechanical control (physical switch operations) with automatic sensing technology. The microwave sensing module detects human activity and the processing unit translates this into electrical control signals, substituting the mechanical control panel or remote controller with an automated sensing-and-control system.
2Adaptability or versatility
If the fan operates continuously or at fixed power levels, then it provides consistent performance, but it cannot adapt to dynamic environmental changes or save energy
Solution Approach 1:
The fan driving device dynamically adjusts its operation based on real-time environmental conditions and human activity detection. Instead of fixed power levels, the system continuously adapts by regulating power according to the presence and activity of humans, enabling the fan to respond flexibly to changing conditions.
Solution Approach 2:
The sensing unit periodically outputs sensing signals to the processing unit based on microwave detection. This feedback mechanism allows the system to continuously monitor environmental conditions and adjust fan operation accordingly, creating a closed-loop control system that optimizes energy consumption based on actual needs.
3Extent of automation
If the fan lacks automatic sensing capability, then the device structure remains simple, but it cannot automatically turn on/off or regulate power based on human activity
Solution Approach 1:
The processing unit serves multiple functions: it processes sensing signals from the microwave sensing module, determines whether human activity exists, controls fan turn-on and turn-off, and regulates working power. This multi-functional design integrates sensing, decision-making, and actuation into a single control unit, managing complexity through functional integration.
