Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a centralized power supply system is used for all electrical devices, then power distribution is simplified, but the system lacks flexibility for different device power requirements
Solution Approach 1:
The power supply system is segmented into a centralized power supply unit and multiple independent fuse heads, each with its own adjustable converter. This allows the system to maintain centralized power distribution while providing localized power adjustment capabilities for different device requirements.
Solution Approach 2:
Each fuse head is equipped with an adjustable converter that can dynamically adapt power output to match the specific requirements of different electrical devices. This dynamic adjustment capability resolves the contradiction between simplified centralized distribution and flexible device-specific power requirements.
2Device complexity
If fixed power supply voltage is provided to all devices, then the power supply system is simpler, but it cannot accommodate devices with different voltage requirements
Solution Approach 1:
Each fuse head is equipped with an adjustable converter that provides locally adapted voltage output according to the specific device connected. This allows the overall system to maintain a simple fixed voltage distribution while each local unit can adjust to the specific voltage requirements of different devices.
3Productivity
If multiple electrical devices are connected to the same power supply, then power distribution efficiency increases, but the risk of overload increases
Solution Approach 1:
The system incorporates monitoring circuits in each fuse head that detect the actual power consumption of connected devices. This feedback information is transmitted to the power supply unit, which automatically adjusts power distribution to prevent overload while maintaining efficient utilization of power resources.
Solution Approach 2:
The power supply system dynamically adjusts power allocation based on real-time monitoring of device power consumption. This dynamic control allows multiple devices to be connected efficiently while automatically preventing overload conditions through adaptive power management.
4Adaptability or versatility
If modular fuse heads with adjustable converters are used, then adaptability to different devices increases, but device complexity increases
Solution Approach 1:
The fuse heads are designed as universal modules with adjustable converters that can adapt to different device types and power requirements. This multi-functionality provides high adaptability while using standardized modular components that reduce overall system complexity through reuse and standardization.
