Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If main signal processors are used for continuous signal processing, then real-time data acquisition is enabled, but defects in main signal processors lead to performance degradation and errors
Solution Approach 1:
The system changes the operational state of signal processors by switching between main and auxiliary processors based on detected defects. When a main signal processor shows performance degradation or errors, the system activates the corresponding auxiliary signal processor to take over the signal processing task, thereby maintaining reliable operation without requiring complex external intervention or system reconfiguration.
2Duration of action of stationary object
If auxiliary signal processors are integrated in a single IC package, then real-time replacement is enabled, but device complexity increases
Solution Approach 1:
The integrated circuit is segmented into distinct functional units: main signal processors, auxiliary signal processors, defect detection units, and switching units. Each segment performs a specific function, allowing the system to maintain complexity while enabling real-time replacement capabilities. The segmentation facilitates modular defect management and extends the operational lifespan of the device.
Solution Approach 2:
The auxiliary signal processors are nested within the same IC package as the main signal processors, creating a compact hierarchical structure. This nesting allows the auxiliary processors to remain in standby mode within the package, ready to replace main processors when defects are detected, thereby extending usage period without requiring separate external components.
3Productivity
If defect detection and replacement is implemented, then production yield is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary defect detection on main signal processors before they fail completely. The defect detection unit continuously monitors processor performance and activates auxiliary signal processors in advance when degradation is detected. This preliminary action prevents complete system failure and improves production yield by maintaining operational capability throughout the manufacturing and usage process.
Solution Approach 2:
The system performs self-diagnosis and self-repair through automated defect detection and auxiliary processor activation. When a main signal processor defect is detected, the switching unit automatically activates the corresponding auxiliary processor without external intervention. This self-service capability improves productivity by reducing manual testing and repair requirements while managing system complexity through automation.
