Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual simulation-based debugging is used to test control software, then testing can be performed, but the process consumes excessive time and labor resources
Solution Approach 1:
The system automatically injects fault signals and collects test results without manual intervention. The control software itself is tested through automated injection of fault signals into the simulation environment, eliminating the need for manual debugging operations and significantly reducing time consumption.
Solution Approach 2:
Manual mechanical debugging operations are replaced by an automated electronic system. The patent uses automated fault signal injection mechanisms to substitute human operators, transforming a manual process into an automated electronic testing system that operates without human intervention.
2Reliability
If multiple fault signals are tested manually in sequence, then comprehensive testing is achieved, but the process becomes extremely labor-intensive and inefficient
Solution Approach 1:
The system continuously injects multiple fault signals in sequence without interruption. After each fault signal is injected and tested, the system automatically proceeds to the next fault signal, maintaining continuous testing operation. This eliminates idle time between tests and maximizes debugging productivity.
Solution Approach 2:
The patent extracts and isolates individual fault signals for systematic testing. Each fault signal is separately injected into the simulation environment, allowing comprehensive testing of multiple fault conditions while maintaining organized and efficient test execution.
3Productivity
If automated fault signal injection is implemented, then debugging efficiency is enhanced, but system complexity increases
Solution Approach 1:
The automated testing system is designed to handle multiple fault signals through a single unified platform. The system can inject various types of fault signals, collect test results, and manage the entire debugging process through one multi-functional apparatus, reducing complexity compared to having separate systems for each function.
