Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional aerosol generating devices use constant heating without temperature control, then the heating element can be simple in structure, but the atomizing medium cannot be maintained within optimal temperature range, causing incomplete melting or liquid leakage
Solution Approach 1:
The patent implements a feedback control system where a temperature sensing element (thermistor) continuously monitors the oil cup temperature and sends signals to the control board. The control board adjusts the heating element's power consumption accordingly, creating a closed-loop feedback mechanism that maintains temperature within the optimal range, thereby resolving the contradiction between reliability and complexity.
Solution Approach 2:
The patent dynamically changes the heating parameter (power consumption) based on temperature conditions. The control board adjusts the power supplied to the heating element according to the detected temperature, enabling adaptive temperature control that prevents both incomplete melting and liquid leakage, thus improving reliability without requiring overly complex hardware.
2Productivity
If the heating element operates at high power continuously, then heating efficiency is improved, but the atomizing medium may boil and leak out of the housing
Solution Approach 1:
The patent transforms the static heating process into a dynamic one by continuously adjusting the heating element's power consumption based on real-time temperature feedback. This dynamic control ensures high heating efficiency when needed while preventing overheating and liquid leakage, resolving the contradiction between productivity and harmful effects.
Solution Approach 2:
The feedback mechanism monitors temperature and automatically reduces heating power when the optimal temperature range is reached, preventing the atomizing medium from boiling and leaking. This resolves the contradiction by maintaining high efficiency during the heating phase while preventing harmful effects during the maintenance phase.
3Reliability
If the heating element operates at low power continuously, then liquid leakage is prevented, but the atomizing medium fails to melt due to insufficient heating temperature
Solution Approach 1:
The heating system operates in periodic cycles, alternating between high-power heating phases and lower-power maintenance phases. During the heating phase, high power melts the atomizing medium efficiently; during the maintenance phase, reduced power maintains temperature stability and prevents leakage, thus resolving the contradiction between melting efficiency and temperature stability.
Solution Approach 2:
The feedback control system detects when the atomizing medium has reached melting temperature and automatically reduces power to maintain stability, ensuring both efficient melting and temperature stability without continuous high-power operation.
