Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing test design techniques for embedded systems face challenges in reliably preventing missing and overlapping test items, especially as requirement items become complex and numerous, requiring an additional index for evaluating relevance.
Innovation Solution
A requirement analysis apparatus that classifies requirement items into groups based on connection information, extracts the number of subsystems reached by tracing connections, and displays analysis results to provide an automatic relevance evaluation index.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If requirement items are illustrated and detailed to reduce missing and overlapping test items, then test item completeness improves, but analysis complexity increases
Solution Approach 1:
The patent segments the complex analysis task into distinct functional units: a connection analysis unit that classifies requirement items into groups, and a subsystem analysis unit that traces connections to subsystems. This segmentation allows each unit to handle specific aspects of the analysis independently, improving reliability while managing complexity through modular architecture.
Solution Approach 2:
The patent introduces an intermediary automated analysis system that mediates between the requirement items and the test design process. This intermediary automatically calculates relevance indices and generates analysis results, reducing the complexity burden on human analysts while ensuring consistent and reliable test item completeness.
2Reliability
If manual analysis of requirement items is performed to evaluate relevance, then test design quality improves, but time consumption increases
Solution Approach 1:
The patent implements a self-service automated analysis system that independently processes requirement items, traces connections, and generates relevance evaluations without requiring manual intervention. The connection analysis unit and subsystem analysis unit automatically perform their functions, significantly reducing time consumption while maintaining high test design quality through consistent automated evaluation.
Solution Approach 2:
The patent replaces the mechanical manual analysis process with an automated computational system. Instead of human analysts manually tracing connections and evaluating relevance, the system uses automated algorithms to perform these tasks, dramatically reducing time consumption while maintaining or improving analysis quality through systematic and repeatable processes.
3Productivity
If requirement items are classified into groups and traced to subsystems automatically, then analysis efficiency improves, but system complexity increases
Solution Approach 1:
The patent segments the automated analysis system into distinct functional modules: a connection analysis unit for classifying requirement items into groups, and a subsystem analysis unit for tracing connections to subsystems. This segmentation improves analysis efficiency by enabling parallel processing of different aspects while managing system complexity through clear modular boundaries and defined interfaces between units.

AI summary
In a requirement analysis apparatus, a connection analysis unit classifies a plurality of requirement items into groups based on connections between requirement items indicated in item connection information. A subsystem analysis unit extracts the number of subsystems that are reached by tracing the connections from each requirement item, based on the connections between the requirement items indicated in the item connection information and based on the connection between each requirement item indicated in the item connection information and each subsystem. A result display unit displays, for each requirement item of the plurality of requirement items, analysis result information which is set with an identifier identifying a group into which the requirement item has been classified, and the number of subsystems being reached by tracing the connections from the requirement item.
