Aerosol Charging Mode Switching During Active Heating Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol-generating devices, such as heat-not-burn devices, face challenges in managing charging operations while ensuring safe and efficient use, particularly when connected to charging devices during active sessions or when capsules are present.
Innovation Solution
A charging system with a processor and memory that enables modes like disable, intra-session, and inter-session, allowing the device to detect connections, manage heater enablement/disabling, and display status, ensuring safe charging and use by suspending or enabling charging based on session status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the device allows charging during active sessions, then charging convenience is improved, but safety risks increase due to potential overheating or improper use
Solution Approach 1:
The charging system dynamically adjusts its behavior based on session status. When a session is detected, the system switches to inter-session mode which suspends charging. When no session is active, the system allows charging. This dynamic adaptation resolves the contradiction by making the charging permission conditional rather than fixed.
Solution Approach 2:
The system continuously monitors session status and uses this feedback to control charging behavior. The processor detects whether a session is ongoing and automatically enables or suspends charging accordingly. This feedback loop ensures that charging only occurs when safe, resolving the safety concern while maintaining convenience when appropriate.
2Reliability
If the device suspends charging during sessions, then safety is improved, but charging time increases due to interruptions
Solution Approach 1:
The system implements periodic monitoring of session status during charging. Instead of continuous interruption, the system checks at defined intervals whether a session is active and adjusts charging accordingly. This periodic approach minimizes charging time loss while maintaining safety through regular status verification.
Solution Approach 2:
The system proactively suspends charging before a session begins by detecting session initiation signals in advance. This preliminary action prevents unsafe charging conditions from occurring, ensuring safety is maintained without requiring reactive interruptions that would extend charging time.
3Adaptability or versatility
If the device enables heater during charging, then device functionality is improved, but energy consumption increases and safety risks arise
Solution Approach 1:
The heater control is dynamically linked to charging status. When charging is suspended (during sessions), the heater is automatically disabled to reduce energy consumption and eliminate safety risks. When charging is enabled (inter-session periods), the heater can operate normally. This dynamic coupling resolves the contradiction by making heater operation conditional on safe energy availability.
Solution Approach 2:
The system uses feedback from the charging status to control heater operation. The processor monitors whether charging is currently enabled and uses this information to automatically enable or disable the heater. This feedback mechanism ensures the heater only operates when energy is safely available, reducing both energy waste and safety risks while maintaining full functionality when appropriate.
Data Source
AI summary
A charging system for an aerosol-generating device includes a processor and a memory in communication with the processor and configured to store instructions is provided. The instructions define at least one of a disable mode, an intra-session mode, or an inter-session mode. The processor is configured to execute the instructions to cause the charging system to detect when the device is connected to a charging device; activate a power source charger in response to the connection to the charging device; identify a selected mode; enable or disable a heater of the capsule dependent upon the selected mode; if the heater is enabled, display a first display indicating the connection of the charging device; if the heater is enabled, detect if a session of the aerosol-generating device is ongoing; and if the session is ongoing, enable or suspend charging in response to the identification of the selected mode.
