Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic control unit and turbojet regulation system are made compatible, then the control system can function properly, but the system complexity increases and maintenance becomes more difficult
Solution Approach 1:
The patent segments the control architecture by introducing a central computing means that independently controls both the control unit and regulating device. This segmentation allows each component to operate autonomously without requiring compatibility between previously interconnected systems, thereby reducing overall system complexity while maintaining functionality.
Solution Approach 2:
The computing means acts as an intermediary that receives information from sensors and independently processes control signals to both the control unit and regulating device. This intermediary role eliminates the need for direct compatibility between the control unit and regulating device, as all communication flows through the centralized computing means.
2Reliability
If the electronic control unit and turbojet regulation system are made compatible, then the control system can function properly, but maintenance complexity increases
Solution Approach 1:
By segmenting the control system into independent components (sensors, computing means, control unit, regulating device), the patent enables isolated maintenance and repair of individual components without affecting the entire system. This segmentation simplifies maintenance procedures compared to previously interconnected compatible systems.
Solution Approach 2:
The patent extracts the compatibility requirement from the system architecture by introducing a centralized computing means that handles all processing. This extraction allows the control unit and regulating device to be maintained independently without needing to maintain compatibility relationships, thereby easing maintenance complexity.
3Device complexity
If a centralized computing means controls both control unit and regulating device independently, then system simplicity increases, but control precision may be affected
Solution Approach 1:
The patent implements feedback mechanisms where sensors continuously monitor system status and provide information to the computing means. This feedback loop enables the centralized computing means to maintain precise control by continuously adjusting control signals based on actual system state, thereby preserving control precision despite the simplified architecture.
Solution Approach 2:
The computing means is designed as a universal control platform that can perform multiple functions including sensor data processing, control signal generation, and system monitoring. This multi-functionality allows a single centralized unit to maintain the precision previously requiring multiple specialized components, thereby simplifying the system without sacrificing control accuracy.
