Solution Overview
Problem
Existing electronic vaporization devices do not effectively address heat accumulation in vaporizers, leading to potential melting or deformation due to continuous high-frequency inhalations and microphone failures, which can cause overheating and leakage.
Innovation Solution
A main unit connected to the vaporizer, comprising a processor, battery, timer, and memory, which calculates accumulative temperature based on timing information and vaporization temperature change curves to prevent overheating by controlling energy supply and sending prompt messages for user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temperature sensors are installed in the vaporizer to monitor temperature, then temperature measurement precision is improved, but device complexity increases and manufacturing cost rises
Solution Approach 1:
The patent creates a virtual copy of the temperature sensor by using the existing timer and stored temperature-time curve data to calculate and represent temperature information, eliminating the need for physical temperature sensors in the vaporizer
Solution Approach 2:
The patent introduces timing information as an intermediary element that connects the existing timer function to temperature monitoring, using the relationship between time and temperature from pre-stored curves to infer temperature without direct measurement
2Reliability
If protection is provided for continuous inhalation of certain duration, then reliability is improved, but the impact of heat accumulation from multiple inhalations is not addressed
Solution Approach 1:
The patent implements feedback by continuously calculating accumulative temperature based on timing information from multiple inhalation events and comparing it against safety thresholds, enabling the system to respond to heat accumulation patterns
Solution Approach 2:
The patent performs preliminary action by pre-storing temperature change curves and their corresponding time information in the memory before actual use, enabling real-time temperature calculation without requiring complex real-time temperature measurement hardware
3Productivity
If high-frequency continuous inhalations occur, then productivity is improved, but heat accumulates in the vaporizer causing melting or deformation
Solution Approach 1:
The patent applies beforehand cushioning by calculating accumulative temperature in advance and issuing warnings or stopping heating before the vaporizer temperature reaches dangerous levels that would cause melting or deformation
Solution Approach 2:
The patent replaces the mechanical/physical temperature sensing system with an information-processing approach, using the processor to calculate temperature based on timing data and pre-stored curves, thereby avoiding the need for physical temperature sensors in the vaporizer structure

AI summary
A main unit connected to a vaporizer and controlling operation of the vaporizer includes: a processor; and a battery, a timer, and a memory that are connected to the processor. The processor controls the battery to provide energy for the vaporizer to allow the vaporizer to vaporize an aerosol-generating substrate. The processor calculates an accumulative temperature during vaporization of the vaporizer based on timing information of the timer and a vaporization temperature change curve stored in the memory.
