Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing aerosol generating devices face challenges in accurately identifying and authenticating aerosolisable medium articles, particularly due to deposition of particles on optical sensors, which impairs their ability to read indicia and may lead to the use of counterfeit or non-genuine products.

Innovation Solution

The apparatus incorporates a sensor arrangement with a cover system that can move between obstructing and unobstructing the sensor's field of view, and includes a compressible surface for cleaning the sensor during article insertion, along with capacitive and optical sensors to detect indicia and authenticate articles, ensuring proper operation and preventing use of non-genuine products.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed cover system is used to protect the sensor, then the sensor is continuously protected from contamination, but the sensor cannot accurately detect indicia on articles

Engineering Contradiction:

Improvesensor protectionVSAvoidindicia detection accuracy

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The cover system is designed to dynamically change its position between a first configuration that substantially covers the sensor and a second configuration that leaves the sensor exposed. This dynamic positioning allows the system to switch between protecting the sensor and enabling accurate indicia detection, resolving the contradiction between continuous protection and detection accuracy.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The cover system is segmented into multiple portions that can be independently positioned. This segmentation allows selective coverage of the sensor while maintaining the ability to detect indicia on articles, enabling the system to balance protection and detection requirements through strategic positioning of cover portions.

Inventive Principle:

Principle #1Segmentation

2Measurement precision

If the sensor is exposed to detect indicia, then article identification accuracy is improved, but the sensor becomes contaminated with particles

Engineering Contradiction:

Improvearticle identification accuracyVSAvoidsensor contamination

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by positioning the cover system in the first configuration (protective position) before article insertion. After detecting the article and its indicia, the cover is repositioned to the second configuration. This preliminary protective positioning prevents contamination before it occurs while still allowing detection when needed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The cover system acts as an intermediary element between the sensor and the article environment. It can be positioned to block contamination pathways when not in use, and repositioned to allow indicia detection, serving as a protective mediator that enables both sensor protection and accurate detection through controlled positioning.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If the cover system is frequently opened for sensing, then indicia detection is enabled, but the risk of contamination increases

Engineering Contradiction:

Improvesensing operationVSAvoidsensor cleanliness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system uses feedback from the sensor to control the cover system positioning. When indicia detection is required, the system receives feedback that triggers cover repositioning to the second configuration. After sensing, the cover returns to the first configuration. This feedback-driven control enables easy sensing operation while maintaining sensor cleanliness through automated positioning responses.

Inventive Principle:

Principle #23Feedback
