Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioner control systems face difficulties in effectively managing and interpreting the vast amount of data from multiple indoor units, making it challenging to determine the operational state and diagnose issues within the air conditioner system.
Innovation Solution
A control apparatus connected to both indoor and outdoor units of the air conditioner, which processes and displays data in real-time, using graphical and visual representations to facilitate easy monitoring and troubleshooting, including a central controller with a microprocessor, communication modules, and storage media for data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If data from multiple indoor units is collected and processed, then monitoring capability is improved, but device complexity increases
Solution Approach 1:
The system divides the monitoring function into two parts: the control apparatus collects and stores raw data from multiple indoor units, while the separate terminal device performs the complex data processing and graphical display. This segmentation allows the control apparatus to remain relatively simple while achieving comprehensive monitoring capability through the terminal device's analytical functions.
2Productivity
If real-time data processing is implemented, then troubleshooting efficiency is improved, but use of energy increases
Solution Approach 1:
The system implements periodic data collection at predetermined intervals rather than continuous real-time processing. The control apparatus collects data from indoor units at set intervals, stores it, and allows the terminal device to process this periodic data stream. This approach maintains troubleshooting efficiency by providing timely data while significantly reducing energy consumption compared to continuous real-time processing.
3Ease of operation
If graphical representations of cycle data are displayed, then ease of operation is improved, but loss of information increases
Solution Approach 1:
The terminal device acts as an intermediary that receives raw cycle data from the control apparatus, processes this data into meaningful graphical representations, and presents it to the user in an easily interpretable format. This intermediary processing layer transforms complex raw data into visual displays showing operational states and errors, improving ease of operation while preserving all essential information through structured graphical presentation.
