Air conditioning control device and method for controlling an air conditioning appliance and a wind-blowing appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioning appliances cannot utilize sensors for room temperature control when powered off, leading to discomfort and inability to adjust to unpredictable temperature changes, as the sensor and control units cease operation when the device is shut down.
Innovation Solution
A device equipped with a sensor and control units that remain operational even when the main functional parts are shut down, using a power supply unit to directly power the sensor and first control unit, and a switching unit to control the second control unit, allowing for continuous monitoring and adjustment of environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the air conditioning appliance is shut down to save energy, then power consumption is reduced, but the sensor cannot operate and cannot detect temperature changes
Solution Approach 1:
The power supply system is segmented into two independent paths: one path supplies power to the sensor and first control unit continuously, while the other path supplies power to the second control unit and functional parts only when needed. This segmentation allows the sensor to operate independently of the main appliance shutdown state.
Solution Approach 2:
The sensor and first control unit are kept in a ready state by continuous power supply before the appliance is actually needed to operate. This preliminary action ensures that temperature monitoring is already underway and data is collected even when the appliance appears to be off, enabling rapid response to temperature changes.
2Reliability
If the sensor operates continuously to monitor temperature, then temperature control reliability is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts its operational state based on needs: the sensor operates continuously with low power consumption, while the high-power second control unit and functional parts are activated only when temperature adjustment is actually required. This dynamic state management optimizes the balance between monitoring reliability and energy consumption.
Solution Approach 2:
The sensor and first control unit autonomously monitor temperature and detect changes without requiring manual activation or full appliance operation. The system serves itself by automatically determining when activation is needed based on temperature data, eliminating the need for continuous high-power operation.
3Speed
If the second control unit is always powered on to respond quickly to temperature changes, then responsiveness is improved, but power consumption increases
Solution Approach 1:
Temperature monitoring and data collection are performed in advance by the always-on sensor and first control unit, preparing the system for rapid response. When temperature adjustment is needed, the pre-collected data enables the second control unit to activate immediately with full power without waiting for detection delays.
Solution Approach 2:
The first control unit acts as an intermediary between the sensor and the second control unit. It processes temperature data and determines when activation is necessary, then triggers the second control unit only at those moments. This intermediary role enables rapid response while avoiding continuous high-power consumption.
