Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If unidirectional power transmission is used from docking station to water dispenser, then power supply is simplified, but power management efficiency deteriorates and electric shock risk increases during maintenance
Solution Approach 1:
The patent implements bidirectional power transmission capability, allowing power to flow both from the docking station to the water dispenser and from the water dispenser back to the docking station. This inversion of the traditional unidirectional power flow enables the auxiliary battery to discharge back to the docking station, improving power management efficiency by recovering energy that would otherwise be wasted, while maintaining simplified power supply structure through the use of existing wireless power transmission infrastructure.
2Reliability
If auxiliary battery discharge is unrestricted, then continuous operation is ensured, but electric shock risk increases during maintenance
Solution Approach 1:
The controller monitors the operational state of the water dispenser and provides feedback control over the auxiliary battery discharge. During maintenance modes, the controller detects the maintenance state and automatically restricts auxiliary battery discharge to prevent electric shock risk, while allowing unrestricted discharge during normal operation to ensure continuous operation. This feedback mechanism dynamically adjusts power management based on real-time conditions.
3Ease of operation
If wireless power transmission is implemented, then power connection flexibility is improved, but power transmission control complexity increases
Solution Approach 1:
The system implements self-service power management through automated controller logic that handles wireless power transmission control. The controller automatically manages power reception from the docking station, auxiliary battery charging, and discharge control based on operational conditions, eliminating the need for complex manual intervention. This self-service approach maintains ease of operation while managing power transmission control complexity through automated decision-making algorithms.
