Atomiser Memory Chip Tracks Resistor Wear for Flavor Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The wear of the resistor in electronic cigarette atomisers over time affects the flavor of the vaporized liquid, making it increasingly bitter, and is not easily detectable, leading to a compromised vaping experience due to the lack of visual accessibility and prompt replacement notification.
Innovation Solution
An electronic cigarette with a memory chip in the atomiser that tracks the remaining time of use and adjusts the power supply to the resistor, either reducing it or making it unusable when the predetermined maximum time is reached, allowing for timely replacement notification without disrupting vaping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the resistor is used continuously without monitoring, then the device complexity is reduced, but the flavor quality deteriorates due to resistor wear
Solution Approach 1:
The patent implements a memory chip that pre-stores the maximum usage time of the resistor. The control circuit continuously monitors and accumulates usage time, comparing it against the predetermined limit stored in memory. This preliminary action approach allows the system to proactively track resistor degradation before it significantly impacts flavor quality, resolving the contradiction by adding minimal complexity while maintaining flavor consistency throughout the resistor's operational life.
2Object-generated harmful factors
If the resistor wear is monitored continuously, then the flavor quality is maintained, but the device complexity increases
Solution Approach 1:
The memory chip autonomously stores the maximum usage time parameter, and the control circuit automatically accumulates usage time and compares it against the stored limit. This self-service mechanism eliminates the need for external monitoring systems or complex user intervention, maintaining flavor quality through automatic resistor wear tracking while minimizing the added device complexity. The system serves itself by autonomously managing the monitoring and replacement notification functions.
3Difficulty of detecting and measuring
If the atomiser is made visually accessible, then the wear detection is improved, but the device complexity increases
Solution Approach 1:
The patent replaces the mechanical/visual inspection method with an electronic monitoring system. Instead of requiring users to visually examine the resistor through a transparent housing, the control circuit electronically tracks usage time and automatically compares it against the predetermined limit stored in memory. This substitution of electronic monitoring for visual inspection improves wear detection accuracy while adding minimal complexity, as the electronic system requires only simple circuitry and memory storage rather than complex transparent structures or user intervention.
