Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new controller is designed to receive signals from both wireless temperature sensor unit and suction air temperature sensor, then the air-conditioning device can utilize multiple temperature indices for control operations, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent introduces a signal generation unit as an intermediary component that receives signals from both the wireless temperature sensor unit and the suction air temperature sensor, processes them, and generates a single composite signal. This mediator handles the complexity of multiple sensor inputs, allowing the existing controller to remain simple while still utilizing multiple temperature indices for control decisions.
2Adaptability or versatility
If a new controller is designed to receive signals from both wireless temperature sensor unit and suction air temperature sensor, then the air-conditioning device can utilize multiple temperature indices for control operations, but the manufacturing cost increases
Solution Approach 1:
The signal generation unit serves as a cost-effective intermediary that consolidates multiple sensor inputs into a single processed signal. By placing the complex signal processing logic in this dedicated intermediary unit rather than redesigning the entire controller, the manufacturing cost is controlled while still achieving the capability to utilize multiple temperature indices.
3Ease of manufacture
If the existing controller is used with only one temperature index, then the device complexity and manufacturing cost are kept low, but the ability to utilize wireless temperature sensor unit is lost
Solution Approach 1:
The patent segments the temperature sensing and signal processing functions into separate modular components: the wireless temperature sensor unit, the suction air temperature sensor, and the signal generation unit. This segmentation allows the existing simple controller to remain unchanged while adding capability through modular components that can be selectively integrated.
Solution Approach 2:
The signal generation unit acts as an intermediary that bridges between the multiple temperature sensors and the simple existing controller. It processes signals from both sensors and presents a single composite signal to the controller, enabling the controller to utilize wireless temperature data without requiring complex redesign.
