Aerosol Generator Power Control via Usage Counter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol provision systems, such as e-cigarettes, face issues with component degradation and reliability due to continuous use, leading to unpredictable operation and potential device failure, as the lifespan of consumable cartridges is limited by the aerosol-generating material volume rather than the components' durability.
Innovation Solution
Incorporating an article control circuitry that manages electrical power to the aerosol generator based on counters for tracking inhalations and refill status, preventing power supply when limits are reached to prevent overheating and component damage, and enabling power only when the cartridge is filled, thus extending the cartridge's usable life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the article is refilled with aerosol-generating material to extend its life, then the usability of the article is improved, but component degradation and reliability deteriorate due to continuous use
Solution Approach 1:
The patent applies preliminary action by implementing a counter mechanism that tracks usage before component failure occurs. The counter monitors the number of refills and prevents power supply to the aerosol generator when a predetermined limit is reached, thereby proactively preventing component degradation and reliability issues before they manifest during continuous use.
2Productivity
If power is continuously supplied to the aerosol generator during refilling, then the article remains operational, but component damage and overheating worsen
Solution Approach 1:
The patent implements feedback control through a counter mechanism that monitors refill events and provides feedback to the power supply system. When the counter reaches a predetermined value indicating excessive refilling, the system automatically stops power supply to the aerosol generator, preventing component damage and overheating while maintaining operational safety.
3Adaptability or versatility
If the article is designed for unlimited refilling, then the usability is improved, but predictability and reliability worsen due to unknown component lifespan
Solution Approach 1:
The patent applies parameter changes by introducing a predetermined counter limit that transforms the unlimited refilling capability into a controlled process. The counter tracks refill events and changes the power supply state from continuous to limited when the predetermined value is reached, thereby maintaining adaptability while improving operation predictability and reliability through defined usage parameters.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances the reliability and predictability of aerosol provision systems by preventing component degradation and ensuring safe operation by controlling power supply based on refill status and usage limits, thereby extending the cartridge's lifespan and improving user experience.
Implementation Method 1
an aerosol generator, e.g. a heating element, arranged to aerosolize a portion of aerosol-generating material to generate an aerosol in an aerosol generation region of an air channel through the aerosol provision system
Implementation Method 2
air is drawn into the device through one or more inlet holes and along the air channel to the aerosol generation region, where the air mixes with the vaporized aerosol generator and forms a condensation aerosol
