Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air-conditioning systems cannot accurately determine if a space is sufficiently cooled or if temperature distribution is uneven, making it difficult to decide on necessary inspections or repairs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional air-conditioning systems use basic operation history and failure code monitoring, then the system complexity is low, but the inspection decision precision is insufficient
Solution Approach 1:
The patent replaces mechanical temperature sensing with infrared radiation temperature sensors that detect thermal radiation to measure temperature distribution in the air-conditioned space. This substitution enables precise measurement of temperature fields without physical contact, providing detailed spatial temperature data that improves inspection decision precision while maintaining manageable system complexity through wireless communication integration.
Solution Approach 2:
The patent introduces a terminal device as an intermediary between the air-conditioning system and the user. This terminal receives temperature distribution data from the air-conditioning apparatus, processes the information, and presents it in an easily understandable format. The intermediary handles the complexity of data processing and analysis, allowing the air-conditioning system itself to remain relatively simple while achieving high inspection decision precision.
2Measurement precision
If radiation temperature sensors are added to detect temperature distribution, then the temperature measurement precision improves, but the device complexity increases
Solution Approach 1:
The radiation temperature sensor is integrated into the existing air-conditioning apparatus structure, serving multiple functions: monitoring temperature distribution for inspection decisions, verifying cooling/heating effectiveness, and providing data for system optimization. This multi-functionality justifies the added device complexity by delivering comprehensive temperature measurement capabilities that improve overall system performance and inspection accuracy.
3Loss of information
If the system collects and transmits detailed temperature distribution data, then the information completeness improves, but the communication data volume increases
Solution Approach 1:
The terminal device extracts and processes only the essential information from the comprehensive temperature distribution data collected by the air-conditioning apparatus. Instead of transmitting all raw sensor data, the system identifies key temperature variations and anomalies, transmitting only the critical information needed for inspection decisions. This extraction approach maintains information completeness for decision-making while significantly reducing communication data volume.
