Puff-Count Session Control for Heat-Not-Burn Energy Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat-not-burn aerosol-generating devices lack effective session control mechanisms to manage puff duration and frequency, leading to potential overuse and inefficient energy consumption.
Innovation Solution
Implementing a session control system with a processor and memory to detect session start, monitor puff variables and time thresholds, and end sessions based on predefined criteria, including puff count and time limits, with haptic feedback and energy monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If no session control mechanism is implemented, then the device is simple to operate, but energy consumption increases and overuse occurs
Solution Approach 1:
The session control system continuously monitors puff count and session duration, comparing them against predefined thresholds. When thresholds are exceeded, the system provides feedback by ending the heating session or displaying warnings, thereby preventing excessive energy consumption while maintaining acceptable device complexity through automated control
Solution Approach 2:
The system changes operational parameters (heating status, power delivery) based on monitored session parameters (puff count, duration). By dynamically adjusting these parameters according to threshold conditions, the system optimizes energy consumption without requiring complex manual user intervention
2Reliability
If session control with multiple monitoring parameters is implemented, then puff duration and frequency are managed effectively, but device complexity increases
Solution Approach 1:
The session control function is segmented into distinct monitoring tasks: puff detection, duration tracking, threshold comparison, and session termination. This segmentation allows each function to be implemented with simple, dedicated logic rather than a single complex control algorithm, improving reliability while managing complexity
Solution Approach 2:
The control system automatically performs all monitoring and decision-making functions without requiring user intervention. The system self-regulates by detecting puffs, tracking session parameters, and autonomously ending sessions when thresholds are exceeded, thereby achieving reliable session management while minimizing the complexity burden on the user

AI summary
A session control system for a device includes at least one processor and a memory coupled to the at least one processor. The memory is configured to store instructions. The at least one processor is configured to execute the instructions to cause the session control system to detect when a session has started, start a session timer, increment a puff variable when an airflow sensor detects that a puff has been taken, monitor the session timer against a time threshold and the puff variable against a puff threshold, and in response to a session threshold being met, end the session. The session timer is configured to measure a length of the session and the puff variable corresponds to a total number of puffs taken.
