Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If permanently installed batteries are used to power aircraft, then electrical power supply is improved, but aircraft structure complexity and infrastructure requirements increase significantly
Solution Approach 1:
The power system is divided into separate, interchangeable modular power units that can be removed and replaced independently of the aircraft structure. Each module contains its own power generation device, control system, and support systems, allowing the aircraft to be decoupled from permanent installations while maintaining electrical power supply capability
Solution Approach 2:
The modular power units are designed with standardized interfaces that allow them to be used across different aircraft types and configurations. The same module can serve multiple functions including power generation, energy storage, and can be quickly swapped between different aircraft platforms without requiring custom installations
2Adaptability or versatility
If modular power units are used, then adaptability to varying power requirements is improved, but system complexity increases due to multiple subsystems
Solution Approach 1:
Multiple essential subsystems including power generation, control, conditioning, environmental control, and safety systems are merged into a single integrated modular unit. This consolidation reduces the number of separate components that need to be managed and installed, while maintaining the adaptability to varying power requirements through the integrated design
Solution Approach 2:
The modular power units are designed to fit within standardized cargo hold configurations, with components nested efficiently within the module structure. The control system, power generation devices, and support systems are arranged in a nested configuration that optimizes space utilization while maintaining accessibility for maintenance and replacement
