Solution Overview
Problem
Existing aerosol generating devices face challenges in accurately identifying and authenticating aerosolisable medium articles, preventing the use of counterfeit products, and maintaining the effectiveness of optical sensors by minimizing deposition of particles and condensates.
Innovation Solution
The apparatus incorporates a sensor arrangement, including an optical sensor and a cover system, to detect indicia on the aerosolisable medium articles, with features like a retractable sensor and a replaceable cover to minimize deposition and ensure accurate identification, while also allowing for tailored heating profiles based on article characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the optical sensor is exposed to read indicia on articles, then authentication accuracy is improved, but particle and condensate deposition on the sensor increases
Solution Approach 1:
A movable cover is introduced as an intermediary element between the optical sensor and the article. The cover protects the sensor from particle and condensate deposition while allowing optical sensing to occur when positioned to expose the sensor. This mediator resolves the contradiction by enabling authentication accuracy while minimizing harmful deposition.
Solution Approach 2:
The cover system is designed to be movable between a closed protective position and an open sensing position. This dynamic configuration allows the system to adapt: closed during operation to prevent deposition, and open during authentication to enable accurate reading of indicia. The dynamic nature resolves the static contradiction between protection and sensing.
2Reliability
If the sensor is covered to prevent deposition, then sensor effectiveness is maintained, but the ability to sense indicia is reduced
Solution Approach 1:
The movable cover transitions between closed and open states based on operational requirements. When closed, it maintains sensor effectiveness by preventing deposition. When opened, it enables indicia sensing. This dynamic switching resolves the contradiction by allowing the system to achieve both reliability and measurement precision at different times in the operational cycle.
Solution Approach 2:
The cover is positioned to protect the sensor before contamination can occur during aerosol generation. By maintaining protection during operation and only exposing the sensor when needed for authentication, the system preliminarily prevents the problem rather than addressing it after deposition occurs, thus maintaining both effectiveness and sensing capability.
3Device complexity
If a fixed sensor arrangement is used, then device complexity is reduced, but adaptability to different article types is limited
Solution Approach 1:
The movable cover system serves multiple functions: it protects the sensor during operation, enables authentication when opened, and can be designed to accommodate different article types through its movement mechanism. This multi-functionality provides adaptability to different articles while maintaining relatively simple device complexity compared to multiple fixed sensor arrangements.
