1Measurement precision

If manual monitoring methods are used to track data transactions in aircraft communication systems, then system complexity is reduced, but measurement precision and reliability of data coupling validation deteriorate

Engineering Contradiction:

Improvedata coupling validation accuracyVSAvoidmonitoring system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces a data service tracker module as an intermediary component that automatically intercepts and monitors data transactions between shared memory and processes. This tracker acts as a mediator that captures transaction information (read/write operations, process IDs, memory addresses) without requiring manual intervention, thereby improving measurement precision while managing system complexity through automated tracking mechanisms

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements self-service monitoring by automatically building and maintaining a data coupling map through the tracker module. The tracker autonomously records all data transactions, compares them against the expected coupling map, and validates system operation without external manual monitoring, thereby achieving high measurement precision while reducing operational complexity

Inventive Principle:

Principle #25Self-service

2Reliability

If automated tracking of all data transactions is implemented, then measurement precision and reliability improve, but device complexity and processing overhead increase

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the monitoring function into a dedicated data service tracker module that operates independently from the main communication system. This segmentation allows the tracker to focus specifically on capturing and validating data transactions against the coupling map, improving reliability while containing complexity within a modular, manageable component that can be added or removed without affecting the core system

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary action by pre-defining the expected data coupling map before operation begins. This expected map serves as a reference framework that guides the tracker's validation process, allowing the system to automatically verify transactions against known good configurations, thereby improving reliability while reducing the complexity of real-time analysis by comparing against a predetermined structure

Inventive Principle:

Principle #10Preliminary action

3Loss of information

Solution Approach 1:

The patent implements continuous tracking of data transactions through the data service tracker module, which operates continuously to capture all read and write operations to shared memory. This continuous action ensures complete information collection about actual data couplings occurring in the system, reducing information loss by capturing every transaction without gaps, while the automated nature maintains efficiency

Inventive Principle:

Solution Approach 1:

The patent implements a feedback mechanism where the data service tracker continuously compares actual data transactions against the expected coupling map and provides validation feedback. This feedback loop automatically identifies deviations from expected behavior, improving reliability by ensuring the system operates according to specifications, while the automated feedback process maintains productivity by eliminating manual validation requirements
