Aerosol Generator State Control With Sensor-Based User Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electrically operated aerosol generating systems lack user interface flexibility and security, often relying on simple on/off functionality that can lead to accidental activation and lack of user authentication, limiting customization and access control.
Innovation Solution
An aerosol-generating system with a controller that responds to multiple user input actions, including authentication via sensors like accelerometers, fingerprint scanners, and capacitive touch, to transition through states (off, ready, on, active) securely and customize user access, preventing unauthorized use and offering configuration options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple on/off button interface is used, then the system is easy to manufacture and operate, but it lacks security and allows accidental activation
Solution Approach 1:
The activation process is segmented into multiple distinct steps: pressing the button activates a sensor that provides visual feedback, requiring a second press to actually activate the aerosol generation. This segmentation prevents accidental single presses from activating the system while maintaining ease of use through intuitive feedback.
Solution Approach 2:
The system incorporates visual feedback through an indicator that illuminates when the sensor is activated but the system is not yet fully on. This feedback mechanism guides the user through the activation process and confirms the system state, reducing accidental activation while maintaining simplicity.
2Reliability
If authentication sensors (fingerprint, accelerometer, gyroscope) are added, then user security and access control are improved, but device complexity increases
Solution Approach 1:
The button serves multiple functions: it acts as a mechanical interface for activation, triggers sensor-based authentication sequences, and provides user input for various system functions. This multi-functionality reduces the need for separate authentication hardware while maintaining security.
Solution Approach 2:
The patent replaces traditional mechanical authentication systems with sensor-based detection using accelerometers, gyroscopes, and fingerprint sensors that work in conjunction with the button press, reducing mechanical complexity while enhancing security capabilities.
3Reliability
If multiple functional states (off, ready, on, active) are implemented, then system control and security are improved, but the control mechanism becomes more complex
Solution Approach 1:
The system dynamically transitions between four distinct states (off, ready, on, active) based on user input and sensor detection. Each state has specific functionality and access levels, providing granular control while using a unified button interface to manage transitions, balancing complexity with control precision.
Data Source
AI summary
An aerosol-generating system is provided, including a power supply; a controller connected to the supply; an aerosol-generating element connected to the controller; and a first sensor connected to the controller to provide a first signal to the controller in response to a first user input action, the controller being responsive to the first signal to switch from an off state to a ready state in which the controller prevents at least one function of the system but is responsive to a second user input action providing a second signal to the controller, and the controller comparing the second signal with stored data and switching from the ready state to an on state if the second signal matches the stored data, and in the on state the controller is responsive to a third user input action to switch to an active state in which the controller activates the function.
