Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors and control electronics are added to monitor voltage and current at atomizer nozzles and high-voltage source, then monitoring capability and spraying consistency are improved, but device complexity increases
Solution Approach 1:
The patent implements feedback control by using sensors to detect voltage and current at the atomizer nozzles and high-voltage source, then using control electronics to process this information and adjust operation parameters in real-time. This closed-loop feedback system ensures consistent spraying performance while managing the added complexity through systematic control architecture.
Solution Approach 2:
The control electronics serve multiple functions simultaneously: monitoring voltage, monitoring current, processing sensor signals, controlling the high-voltage source, and managing acoustic/haptic feedback. By consolidating these functions into a single multi-functional control unit, the patent reduces overall system complexity despite adding comprehensive monitoring capabilities.
2Reliability
If real-time monitoring and intervention mechanisms are implemented, then error prevention and spraying quality are improved, but device complexity and cost increase
Solution Approach 1:
The control electronics continuously monitor operating parameters and provide real-time feedback to detect anomalies or deviations from optimal spraying conditions. When errors or abnormal conditions are detected, the system automatically intervenes to correct the issue, preventing errors before they affect spraying quality.
Solution Approach 2:
The monitoring system detects potential problems before they lead to actual spraying errors or failures. By identifying voltage fluctuations, current anomalies, or other abnormal conditions in advance, the system can take preliminary corrective action to prevent errors from occurring during the spraying process.
3Ease of operation
If acoustic and haptic feedback systems are added to provide real-time information about spraying operation, then user awareness and control are improved, but device complexity increases
Solution Approach 1:
The system provides real-time feedback to the user through acoustic signals (such as tones or voice prompts) and haptic feedback (such as vibrations). This feedback informs users about the current spraying status, operational mode, and any issues that require attention, greatly improving user awareness and control of the spraying process.
4Manufacturing precision
If comprehensive sensor monitoring of voltage and current is implemented, then spraying precision and quality control are improved, but energy consumption and device complexity increase
Solution Approach 1:
Sensors continuously monitor voltage and current parameters to maintain precise control over the electrostatic atomization process. The control electronics process this data in real-time and adjust operating parameters to optimize spraying precision while managing energy consumption through efficient control algorithms.
