Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigeration quality in refrigerated vehicles can deteriorate due to temperature deviations, making it difficult for drivers to manage effectively, especially when their attention is focused on vehicle operation.
Innovation Solution
A method and device for managing refrigeration quality by early detection of abnormalities in a refrigeration system, utilizing refrigeration quality reference data to determine temperature offsets and duration, and notifying drivers of suspected refrigeration condition abnormalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver focuses attention on vehicle operation, then vehicle operation safety is improved, but refrigeration quality management deteriorates
Solution Approach 1:
The refrigeration management system operates autonomously by automatically monitoring temperature, comparing it against reference data, detecting abnormalities, and notifying the driver without requiring continuous manual intervention. The system serves itself by performing self-diagnosis and self-reporting of refrigeration status.
Solution Approach 2:
The system continuously monitors refrigeration compartment temperature and provides feedback to the driver through notifications when abnormalities are detected. This closed-loop feedback mechanism enables the driver to respond to refrigeration issues without diverting attention from vehicle operation.
2Ease of operation
If manual monitoring of refrigeration temperature is performed, then refrigeration quality management is improved, but driver attention and time consumption increase
Solution Approach 1:
The system automatically performs temperature monitoring, abnormality detection, and driver notification without requiring the driver to manually check or manage refrigeration status, eliminating time consumption for the driver.
Solution Approach 2:
The manual mechanical monitoring process is replaced with an automated electronic system that uses temperature sensors, processors, and communication modules to perform monitoring and reporting functions automatically.
3Measurement precision
If temperature offset detection is performed, then refrigeration abnormality detection is improved, but energy consumption increases
Solution Approach 1:
The system performs temperature comparison and abnormality detection only when necessary, using partial monitoring actions rather than continuous full-scale analysis. The processor compares temperature data against reference values and activates notification only when offsets are detected, reducing unnecessary energy consumption.
Solution Approach 2:
The system changes its monitoring intensity based on temperature conditions, performing detailed offset detection only when temperature deviations are detected. This dynamic parameter adjustment optimizes the balance between detection accuracy and energy consumption.

AI summary
A method and apparatus manage a refrigeration quality for a refrigerated cargo by detecting refrigeration condition abnormality of a refrigeration system of a vehicle. The method includes: receiving refrigeration quality reference data for the refrigerated cargo, obtaining a target temperature and an allowable time range data that are set based on the refrigeration quality reference data, determining whether an offset from the target temperature has occurred, comparing the allowable time range data with a duration for which the offset from the target temperature occurred, and determining, based on comparing the duration of the offset with the allowable time range data, whether the refrigeration system is in a suspected refrigeration condition abnormality state.
