Flavor Inhaler Cartridge Replacement Notification Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing non-burning type flavor inhalers do not notify users about the replacement timing of the first and second cartridges, which impairs user convenience and leads to inefficient usage.
Innovation Solution
A non-burning type flavor inhaler with a power source unit, a first cartridge containing an aerosol source and an atomizer, and a second cartridge with a flavor source, where a controller detects the replacement timing of the cartridges based on puff actions, energization time, and output voltage, and notifies the user through a notification unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the non-burning type flavor inhaler does not include a notification function for cartridge replacement timing, then the device complexity is reduced, but user convenience and operational efficiency deteriorate
Solution Approach 1:
The controller performs preliminary detection of cartridge replacement timing based on puff count or energization time before the cartridge actually needs replacement. The notification unit alerts users in advance, allowing them to prepare for replacement without interrupting usage. This resolves the contradiction by providing user convenience through advance notification while keeping the detection mechanism simple and integrated into existing operational parameters.
Solution Approach 2:
The system implements feedback by continuously monitoring puff actions and energization time, comparing these against predetermined thresholds, and notifying users when replacement timing is detected. This closed-loop feedback mechanism provides user convenience through real-time information while maintaining relatively simple device architecture by using the existing controller and notification infrastructure.
2Measurement precision
If the controller continuously monitors puff actions and energization time to detect replacement timing, then the accuracy of replacement timing detection is improved, but the use of energy increases
Solution Approach 1:
The controller performs detection of replacement timing at periodic intervals based on discrete events (each puff action or energization time threshold) rather than continuous monitoring. The counter increments with each puff or energization event, and replacement timing is detected when predetermined values are reached. This periodic detection approach maintains high measurement precision while significantly reducing energy consumption compared to continuous monitoring.
3Loss of information
If the inhaler provides comprehensive notification for both first cartridge and second cartridge replacement timing, then the information completeness is improved, but the device complexity increases
Solution Approach 1:
The single controller is designed to perform multiple functions: it manages atomizer operation, counts puff actions, monitors energization time, detects replacement timing for both the first cartridge (aerosol source) and second cartridge (flavor source), and controls the notification unit. This multi-functional design provides comprehensive information completeness for both cartridge types while avoiding the need for separate detection systems, thereby limiting the increase in device complexity.
