Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a centralized approach is used for electrical power distribution in aircraft, then the system structure is simple and easy to control, but the flexibility and efficiency of power distribution are reduced
Solution Approach 1:
The patent divides the centralized power distribution system into multiple distributed power management modules, each responsible for specific electrical systems. This segmentation enables localized decision-making at each module level while maintaining overall system coordination, thus improving flexibility without excessive complexity
Solution Approach 2:
The system implements dynamic power distribution by continuously monitoring flight phase, power consumption patterns, and system priorities. The control characteristics are adjusted in real-time based on changing operational conditions, enabling the system to adapt flexibly to different flight scenarios
2Device complexity
If power distribution does not account for flight phase variations, then the control system is simpler, but power usage efficiency decreases
Solution Approach 1:
The system changes control parameters based on flight phase detection. Different power consumption thresholds, priority levels, and distribution strategies are applied during takeoff, cruise, landing, and other phases. This parameter adaptation optimizes power efficiency without requiring complete system redesign
3Device complexity
If uniform power supply is provided to all electrical systems, then power distribution is simpler, but reliability during critical flight phases is reduced
Solution Approach 1:
The patent applies different power supply qualities and priorities to different electrical systems based on their criticality and flight phase requirements. Critical systems receive guaranteed power supply with higher priority during all flight phases, while non-critical systems have adjustable power allocation. This localized quality differentiation ensures reliability without excessive overall complexity
