Vaporizer Analysis System for Reproducing User Puffs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standardized test procedures for vaping devices and traditional cigarettes fail to accurately represent the chemical constituents inhaled by users due to differences in usage habits and device configurations, leading to misrepresentation of actual exposure levels.
Innovation Solution
An electronic vaping device with a heating element, controller, and sensor system that measures operational parameters such as temperature, power, and airflow for each puff, storing this data locally and transmitting it to a remote terminal for analysis, allowing for the reproduction of vapors under actual usage conditions to determine chemical constituents accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standardized test procedures are used for vaping devices, then test results can be obtained under controlled conditions, but the results do not accurately represent actual user exposure levels
Solution Approach 1:
The system dynamically adjusts test parameters to match actual usage patterns. The controller modifies puff duration, frequency, and power levels based on recorded user behavior data, transforming static standardized tests into dynamic tests that replicate real-world conditions while maintaining measurement reliability
Solution Approach 2:
The system incorporates feedback loops where operational parameters from actual device use are fed back into the testing process. The controller uses recorded user behavior data to adjust test conditions, continuously improving the accuracy of chemical constituent quantification while maintaining reliable test results
2Measurement precision
If user-specific control settings and configurations are considered, then accurate representation of actual inhalation can be achieved, but device complexity increases
Solution Approach 1:
The vaping device performs self-monitoring and self-recording of operational parameters without requiring external intervention. The sensor system automatically measures temperature, power, and airflow, while the controller records puff data and transmits it to the remote terminal, reducing the need for complex external testing equipment
Solution Approach 2:
The system integrates multiple functions into a single platform: the sensor system measures operational parameters, the controller manages both device operation and data recording, and the communication interface handles data transmission. This multi-functionality reduces overall system complexity while enabling accurate representation of actual inhalation conditions

AI summary
Provided are a system and method of reproducing individual puffs based on empirical data collected by a plurality of electronic vaping devices during use of the vaping devices by users to inhale vapors. The method involves receiving, over a communication network for each of the plurality of electronic vaping devices: (i) reservoir information indicative of a configuration of a reservoir storing a liquid that is at least partially converted into the vapor, and (ii) a plurality of operational parameters for each of a plurality of puffs drawn by the users. The operational parameters include a first operational parameter measured by a sensor system provided to the respective electronic vaping device. An evaluation vaping device is controlled to reproduce a puff by generating a vapor based on the received reservoir information and the received plurality of operational parameters in effect during the puff that is being reproduced.
