Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual coolant transfer is used for liquid replenishment and drainage, then the system structure remains simple, but the maintenance efficiency is low and the operation is difficult
Solution Approach 1:
The system enables automated self-service liquid replenishment and drainage through the pump and control unit, eliminating the need for manual coolant transfer. The pump automatically draws coolant from the storage tank and transfers it to the liquid-cooled energy storage system when the liquid level is low, and automatically drains coolant when the level is high, making the system serve itself without external intervention.
Solution Approach 2:
The patent replaces the manual mechanical operation of coolant transfer with an automated pump-driven system controlled by electronic control units and sensors. The mechanical action of manually pouring or pumping coolant is substituted by an electrically controlled pump system that responds to liquid level signals, automating the previously manual process.
2Ease of operation
If automated pump system is implemented for liquid replenishment and drainage, then maintenance efficiency is improved, but the device complexity increases
Solution Approach 1:
The pump serves multiple functions: it acts as both a replenishment pump (transferring coolant from storage tank to system when liquid level is low) and a drainage pump (removing coolant from system when liquid level is high). This multi-functionality reduces the need for separate devices and simplifies the overall system architecture while maintaining automated operation capabilities.
Solution Approach 2:
The control unit acts as an intermediary that receives signals from liquid level sensors and automatically controls the pump's operation. This intermediary component coordinates between the sensing system and the actuating system, enabling automated decision-making and execution without manual intervention, thereby improving ease of operation.
3Adaptability or versatility
If switching power supply is used to adapt to different electric power systems, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The switching power supply enables the system to adapt to different electric power systems by changing its operating parameters (input voltage, frequency, phase). It can accept different input voltages and convert them to the required output voltage for the pump and control circuits, allowing the same device to operate in regions with different power systems without hardware modifications.
