Air conditioning controller for controlling an air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable air conditioning controllers face challenges with battery capacity, requiring frequent battery changes when capacity is small and increased weight when capacity is large, affecting operator convenience.
Innovation Solution
The air conditioning controller incorporates an electrical switch that automatically switches between an internal battery and an external power source, using a P-type MOSFET switch and a N-type MOSFET switch to manage power supply, allowing the controller to operate efficiently with minimal battery discharge and reduced weight by utilizing external power when available.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the capacity of the internal battery is increased, then the operating time of the controller is extended, but the weight of the controller becomes heavier
Solution Approach 1:
The power supply system is segmented into two independent power sources: an internal battery for portable operation and an external power source for fixed installation. This segmentation allows the controller to achieve extended operating time through the external power source without increasing the internal battery capacity, thereby avoiding increased weight.
Solution Approach 2:
The controller is designed with multi-functionality to operate in two different modes: portable mode using the internal battery and fixed installation mode using the external power source. The controller unit can universally accept power from either source, allowing the system to achieve extended operating time without being constrained by battery capacity limitations.
2Duration of action of moving object
If the capacity of the internal battery is increased, then the operating time is extended, but the frequency of battery changes becomes more frequent
Solution Approach 1:
The power supply system is divided into internal battery and external power source segments. The external power source can continuously supply power when the controller is installed in the holder, effectively eliminating the need for battery changes and the associated time loss.
Solution Approach 2:
The holder serves as an intermediary device that connects the controller to the external power source. When the controller is placed in the holder, the external power source automatically supplies power through the holder, eliminating the need for battery changes without requiring manual intervention.
3Ease of operation
If the controller is designed to be portable, then the operator can carry it conveniently, but the battery capacity must be limited
Solution Approach 1:
The system is segmented into a portable controller unit with a small internal battery and a stationary holder with an external power source. The controller maintains portability and convenience for carrying, while the stationary holder provides extended operating time through the external power source when the controller is installed in that location.
Solution Approach 2:
The controller dynamically adapts its power source based on its operational state: using the internal battery when portable and the external power source when installed in the holder. This dynamic power source selection allows the controller to maintain both portability and extended operating time without contradiction.
4Ease of operation
If an automatic switching mechanism is added, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The holder acts as an intermediary that automatically manages the power switching between the internal battery and external power source. When the controller is placed in the holder, the holder's connection automatically enables the external power source, eliminating the need for manual switching operations while avoiding complex switching mechanisms within the controller itself.
Solution Approach 2:
The power switching system operates autonomously based on the physical state of the controller-holder connection. The system automatically detects whether the controller is installed in the holder and switches power sources accordingly without requiring user intervention or complex control logic.
