Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Testing safety-critical systems like railway infrastructure is challenging due to complex interdependent components and distributed logic, leading to inefficient and unreliable manual testing processes that require repeated expert analysis.
Innovation Solution
A computer-implemented method generates an integration test model by providing communication means, assigning technical components to control logic charts, creating a test environment, and using a test data model to automate the testing process, ensuring comprehensive and efficient coverage of system interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual testing with expert knowledge is used, then test coverage can be achieved, but the process is time-consuming and requires repeated expert analysis
Solution Approach 1:
The patent creates a virtual model that copies the essential structure and behavior of the actual technical system. This virtual model includes components, interfaces, and communication protocols, allowing automated generation of test sequences without manual expert intervention for each test case.
Solution Approach 2:
The patent performs preliminary analysis of the technical system to extract components, interfaces, and communication protocols before testing. The virtual model is built in advance with all necessary test sequences generated automatically, eliminating the need for repeated expert analysis during the testing phase.
2Reliability
If comprehensive test coverage is pursued, then system safety is improved, but manual testing becomes increasingly complex and error-prone
Solution Approach 1:
The system performs self-testing through automated generation and execution of test sequences. The virtual model automatically generates test cases, executes them, and evaluates results without human intervention, reducing complexity while maintaining comprehensive coverage for safety-critical systems.
Solution Approach 2:
The patent implements automated feedback mechanisms where test results are immediately evaluated and used to determine whether safety requirements are met. This closed-loop approach systematically ensures comprehensive test coverage while reducing manual complexity through automated analysis and reporting.
3Productivity
If automated testing is implemented, then efficiency is improved, but comprehensive coverage of complex system interactions becomes difficult
Solution Approach 1:
The patent segments the complex technical system into discrete components with defined interfaces and communication protocols. The virtual model represents each component and their interactions separately, allowing automated testing to systematically cover all component-level and interface-level interactions while maintaining overall system coverage.
