Aerosol Device Unlocking via Single-Button Password Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol generating devices with a single button for activation can be easily used by unauthorized users, lacking a secure mechanism to prevent unauthorized access.
Innovation Solution
Implement a locking mode that requires multiple user inputs and a password verification process, using an output interface to signal a password input mode and an input interface to receive user inputs, with a controller determining the validity of the password.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single button is used for activation, then ease of operation is improved, but security against unauthorized use deteriorates
Solution Approach 1:
The patent segments the button's function by introducing different input modes (normal mode and password input mode) that are activated by different pressing patterns. The controller distinguishes between a single press (normal activation) and multiple consecutive presses (password input), allowing the same physical button to serve both ease of use and security functions without requiring additional buttons.
2Reliability
If a password input mode is added, then security is improved, but device complexity increases
Solution Approach 1:
The existing single button is made multi-functional by programming it to detect different pressing patterns (single press vs. multiple consecutive presses). The controller is configured to interpret these different input patterns as different commands, eliminating the need for additional physical components while achieving password protection functionality.
Solution Approach 2:
The patent changes the operational parameters of the button by introducing a time-based criterion (predetermined time interval) to distinguish between normal activation and password input. The controller monitors the timing and frequency of button presses, using these parameter changes to determine whether to activate the heater normally or to enter password verification mode.

AI summary
Provided is an aerosol generating device including a heater configured to heat an aerosol generating substance after a locking mode is terminated; an output interface configured to output information indicative of switching from the locking mode to a password input mode; an input interface configured to receive at least one user input including a predetermined input waiting time in the password input mode; and a controller configured to terminate the locking mode based on whether the user input matches a password.
