Solution Overview
Problem
Manufacturers face difficulty in identifying where components of a refrigeration apparatus installed in transport containers are replaced, making it challenging to trace the cause of breakdowns if non-genuine components are used.
Innovation Solution
A record management apparatus that includes a communication unit to acquire and track component identification information at different time points, determining if changes have occurred, and a control unit to manage this information, along with a storage unit to store and analyze production information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If component identification information is not tracked, then the refrigeration apparatus can operate without monitoring, but the manufacturer cannot identify where components were replaced or trace breakdown causes
Solution Approach 1:
The patent applies preliminary action by equipping components with identification information (such as RFID tags or serial numbers) before they are installed in the refrigeration apparatus. This allows the manufacturer to establish a baseline record of original components, enabling future tracking of any replacements that occur during transportation or maintenance.
Solution Approach 2:
The patent implements feedback by creating a closed-loop information system where component identification data is continuously collected, stored, and compared. The record management apparatus receives feedback from communication units that query component IDs at different time points, and this feedback enables the manufacturer to detect unauthorized replacements and trace the location where changes occurred.
2Loss of information
If component replacements are monitored continuously, then replacement locations can be identified, but information storage and processing requirements increase
Solution Approach 1:
The patent applies the taking out principle by extracting only the essential identification information from components rather than storing complete component specifications or historical data. By focusing solely on unique component IDs and comparison timestamps, the system minimizes data storage requirements while maintaining full traceability capability.
Solution Approach 2:
The patent uses copying by creating simplified digital representations of component identification data. Instead of storing complex component information, the system copies and stores only the essential identification markers (such as serial numbers or RFID identifiers), which can then be compared across different time points to detect replacements.
3Reliability
If component identification is implemented, then genuine components can be verified, but the system requires communication units and control logic
Solution Approach 1:
The patent applies self-service by making components inherently identifiable through built-in identification elements (such as RFID tags, barcodes, or embedded sensors). The components essentially identify themselves to the record management apparatus, eliminating the need for complex manual verification systems or invasive monitoring equipment.
Solution Approach 2:
The patent implements universality by designing a standardized component identification system that can be applied across different component types and refrigeration apparatus configurations. The same identification and verification methodology works for various components (compressors, sensors, valves), reducing the need for component-specific tracking systems.

AI summary
An object of the present disclosure is to implement traceability of components of a refrigeration apparatus provided in a container to be transported. Accordingly, the present disclosure is a record management apparatus (7) for managing a record of a change relating to a refrigeration apparatus provided in a container (C) to be transported, the record management apparatus (7) including a communication unit (71) configured to acquire first component identification information for identifying a predetermined type of a component included in the refrigeration apparatus at a first time point and second component identification information for identifying the predetermined type of the component forming the refrigeration apparatus at a second time point after the first time point; and a control unit (70) configured to implement control to determine whether the second component identification information has been changed from the first component identification information.
