Solution Overview
Problem
Existing device information management systems for air conditioning apparatuses are inefficient in collectively managing device information, requiring dedicated communication devices and increasing equipment costs, and lack the ability to transmit only necessary information during maintenance, complicating the acquisition and display of device data.
Innovation Solution
A device information management system utilizing visible light communication between a remote control and a terminal apparatus, where the remote control acts as a light emitter and the terminal apparatus as a light receiver, allowing for the transmission and registration of device information without the need for additional communication devices, enabling easy data acquisition and display of test run results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated transmission and reception devices are installed for short-range communication, then communication reliability is improved, but equipment cost increases
Solution Approach 1:
The invention repurposes the existing display device (LCD screen) to serve dual functions: displaying information to users and transmitting data through visible light communication. By making the display device perform both visual display and communication functions, dedicated transmission devices are eliminated while maintaining communication reliability
Solution Approach 2:
The display device serves itself by using its inherent light-emitting capability to transmit data. The same component that displays information visually also communicates data to terminal apparatuses, eliminating the need for separate dedicated transmission hardware
2Adaptability or versatility
If additional communication devices are installed in existing devices, then communication functionality is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The invention makes the display device multi-functional by enabling it to perform both its original display function and new communication function. This eliminates the need to install additional communication devices in existing air conditioning apparatuses, simplifying both device structure and installation process
Solution Approach 2:
The visible light serves as an intermediary carrier for data transmission. Instead of installing complex communication hardware, the system uses the already-present light output from the display as a medium to encode and transmit device information to terminal apparatuses
3Loss of information
If all device information is transmitted, then information completeness is improved, but information processing complexity increases
Solution Approach 1:
The invention extracts and transmits only the essential device information needed for maintenance and operation through visible light communication. By selecting and transmitting only necessary information rather than all available data, the system maintains information completeness while reducing processing complexity
Solution Approach 2:
The system transmits a partial set of information that is sufficient for maintenance purposes rather than attempting to transmit complete device data. This partial action approach provides adequate information for operational needs without overwhelming the communication channel or requiring complex processing
