Aerosol Inhaler Motion Activation to Prevent Unauthorized Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol-generating systems lack user control over activation, leading to undesirable activations and reduced confidence among users transitioning from combustible systems.
Innovation Solution
An aerosol provision device with control circuitry and a detector that recognizes predetermined movements at the distal end to update activation states and display conditions, allowing authorized users to activate the device through personalized and familiar movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user control over activation is added to prevent unauthorized use, then safety and security are improved, but device complexity increases
Solution Approach 1:
The patent changes the activation parameter from a simple button press to a specific movement pattern (e.g., flicking motion with particular acceleration, velocity, and direction). The detector captures movement parameters and the control circuitry compares them against stored authorized patterns, enabling security without complex authentication hardware.
Solution Approach 2:
The patent replaces traditional mechanical activation (button press, switch) with a motion detection system using accelerometers or gyroscopes. This substitutes complex mechanical authentication mechanisms with electronic sensor-based movement recognition, reducing physical complexity while maintaining security.
2Reliability
If movement detection is implemented to identify authorized users, then unauthorized use is prevented, but ease of operation decreases
Solution Approach 1:
The patent implements dynamic movement patterns for activation (e.g., flicking, tapping, or swirling motions) that are naturally intuitive and easy to perform. These dynamic gestures replace static button presses, maintaining ease of operation while enabling user identification through movement characteristics.
Solution Approach 2:
The system uses the user's own natural movements to authenticate them, eliminating the need for separate authentication steps. The movement detection leverages the user's inherent motor patterns, making the security mechanism transparent and effortless to use.
3Measurement precision
If predetermined movement patterns are required for activation, then user identification accuracy is improved, but difficulty of detecting and measuring increases
Solution Approach 1:
The patent detects only the essential characteristics of the predetermined movement pattern (e.g., direction, speed, acceleration) rather than attempting to capture every nuance of the user's motion. This partial detection approach achieves sufficient identification accuracy while simplifying the measurement requirements.
Solution Approach 2:
The control circuitry is pre-programmed with stored movement patterns that represent authorized users. This preliminary configuration allows the system to quickly compare detected movements against known patterns, reducing the complexity of real-time analysis while maintaining high identification accuracy.
