Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standby battery source is implemented to ensure continuous power supply, then reliability is improved, but maintenance requirements increase and safety hazards arise
Solution Approach 1:
The patent removes the battery component from the power supply system entirely, extracting the harmful element (electrolyte-containing battery) while maintaining the backup power capability through alternative means (external power source connected via power switching component). This eliminates fire hazards and electrolyte leak risks while preserving reliability.
Solution Approach 2:
The power switching component serves as an intermediary device that manages power flow between the primary power source, external power source, and electronic flight bag. It enables seamless transition between power sources without requiring a standby battery, thus maintaining reliability while eliminating battery-related safety hazards.
2Reliability
If a standby battery source is implemented to ensure continuous power supply, then reliability is improved, but maintenance costs increase
Solution Approach 1:
The patent removes the battery component from the system, eliminating the need for repetitive battery maintenance, replacement, and disposal. The external power source approach requires no physical maintenance of power storage components, significantly reducing life cycle costs while maintaining continuous power capability.
Solution Approach 2:
The system uses the aircraft's existing external power infrastructure and power switching capabilities, leveraging already-maintained aircraft systems rather than introducing a separate battery maintenance regime. The power switching component integrates with existing aircraft power management systems.
