Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a battery system is used to power the vehicle, then the vehicle can operate electrically, but the cruising distance is insufficient and constant recharging is required
Solution Approach 1:
The power supply system is segmented into multiple independent power sources (battery system, solar power generation device, wind power generation device) that can operate independently or in combination. Each power source has its own conversion circuit and control module, allowing the system to divide the power supply function across multiple sources to extend cruising distance and reduce recharging frequency.
Solution Approach 2:
The conversion device is designed with universal input ports that can accept power from multiple different sources (battery, solar panels, wind turbines, external charging stations). The system can universally convert various types of input power into usable forms for the vehicle, making the power supply system adaptable to different energy sources and eliminating the need for specialized recharging infrastructure.
2Reliability
If multiple power sources are connected to ensure continuous power supply, then power interruption is avoided, but the system complexity increases
Solution Approach 1:
Multiple power sources and conversion circuits are merged into a single integrated conversion device with a common control module. The input ports of different conversion circuits are connected together, allowing any power source to feed into any conversion circuit. This merging reduces the overall system complexity by consolidating control functions and power distribution pathways while maintaining the reliability benefits of multiple power sources.
Solution Approach 2:
The control module automatically monitors the status of all power sources and conversion circuits, and autonomously selects and switches between available power sources without external intervention. The system performs self-diagnosis and self-adjustment to maintain continuous power supply, reducing the need for complex manual control systems while ensuring high reliability.
3Adaptability or versatility
If conversion circuits are provided for each power source, then power conversion flexibility is improved, but the device complexity increases
Solution Approach 1:
The system employs dynamic switching capabilities where the connection between power sources and conversion circuits is not fixed but can be dynamically reconfigured. The control module can dynamically assign any power source to any conversion circuit based on real-time conditions, allowing the system to adapt to different operating scenarios without requiring dedicated conversion circuits for each power source combination, thus reducing overall complexity while maintaining flexibility.
