Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manually dropwise adding manner is used for e-liquid supply, then operation simplicity is maintained, but operation frequency increases and user experience deteriorates
Solution Approach 1:
The system enables self-service by using a temperature detector to automatically monitor atomization temperature and a peristaltic pump to automatically adjust e-liquid supply based on temperature feedback, eliminating the need for frequent manual e-liquid addition while maintaining simple operation
Solution Approach 2:
The system implements feedback control by detecting real-time atomization temperature and using this information to automatically regulate e-liquid supply quantity, ensuring the atomizer maintains optimal temperature without manual intervention
2Loss of time
If manually extruding manner is used for e-liquid supply, then operation frequency is reduced, but supply accuracy deteriorates causing overheating or leakage
Solution Approach 1:
The temperature detector continuously monitors atomization temperature and provides feedback to the control system, which automatically adjusts the peristaltic pump to deliver precise e-liquid quantities, preventing both overheating (insufficient supply) and leakage (excessive supply)
Solution Approach 2:
The system replaces manual mechanical extrusion with an automated peristaltic pump controlled by temperature feedback, achieving precise e-liquid metering and delivery without manual intervention while maintaining supply accuracy
3Manufacturing precision
If automatic temperature-based control is implemented, then supply accuracy is improved, but device complexity increases
Solution Approach 1:
The system replaces complex manual control mechanisms with an automated control circuit that uses simple temperature detection and electronic control of the peristaltic pump, achieving high supply accuracy through electronic feedback rather than mechanical complexity
