Aerosol Provision Device Fingerprint Scanning for Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol provision systems lack effective user authentication mechanisms to prevent unauthorized activation, particularly in situations where control over activation is desirable.
Innovation Solution
An aerosol provision device equipped with a fingerprint scanner covering at least 40% of its outward-facing surface, which identifies authorized users by detecting fingerprints and controls device activation accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fingerprint scanner is added to control device activation, then security against unauthorized use is improved, but device complexity increases
Solution Approach 1:
The fingerprint scanner is integrated into the housing surface, merging the authentication function with the device structure itself. The scanner becomes part of the housing rather than a separate component, reducing overall system complexity while maintaining security functionality.
Solution Approach 2:
The outwardly facing surface of the housing serves multiple purposes: it provides the structural exterior of the device and simultaneously hosts the fingerprint scanner for authentication. This multi-functional use of the housing surface addresses security needs without adding dedicated separate components.
2Ease of operation
If the fingerprint scanner covers a large surface area (at least 40% of outwardly facing surface), then ease of operation is improved, but the area available for other functions is reduced
Solution Approach 1:
The fingerprint scanner is positioned to cover at least 40% of the outwardly facing surface, concentrating the authentication function in a specific large area. This local concentration of functionality ensures easy user interaction while the remaining surface area can be allocated to other device functions or aesthetic considerations.
Solution Approach 2:
The scanner surface area requirement transforms a two-dimensional space constraint into a functional requirement. By specifying that the scanner must cover at least 40% of the outwardly facing surface, the patent ensures sufficient interaction area for ease of operation while allowing flexible allocation of the remaining surface area for other purposes.
