1Object-affected harmful factors
If heat output is capped to prevent overheating when vaporizable substance is depleted, then device damage is prevented, but vapor generation reliability deteriorates
Solution Approach 1:
The system performs preliminary monitoring of vaporizable substance levels and predicts depletion before it occurs. By tracking usage patterns and substance consumption rates, the system proactively adjusts heating parameters or alerts the user, preventing overheating damage while maintaining optimal vapor generation during the substance's usable life.
Solution Approach 2:
The system continuously monitors temperature, heating element resistance, and usage patterns to detect changes indicating substance depletion. This feedback loop allows the system to dynamically adjust heating power or shut down the heater, preventing damage while ensuring reliable vapor generation during normal operation through real-time condition assessment.
2Productivity
If heating power is increased to ensure reliable vapor generation, then vapor production is improved, but risk of overheating and damage increases
Solution Approach 1:
The system dynamically adjusts heating power based on real-time monitoring of temperature, substance levels, and usage patterns. During normal operation with sufficient vaporizable substance, higher power is applied for efficient vapor generation. As substance depletes or temperature rises, power is automatically reduced, maintaining productivity while preventing overheating damage through continuous adaptation.
Solution Approach 2:
The system changes operational parameters including heating power, temperature thresholds, and timing based on detected substance levels and thermal conditions. By modifying these parameters dynamically, the system optimizes vapor generation efficiency when substance is abundant while preventing overheating when substance is depleted, resolving the contradiction between productivity and safety.
