Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a contact surface is used between the aerosol provision device and aerosol generating article, then the device can effectively heat and process the article, but the contact surface becomes dirty over time which degrades performance
Solution Approach 1:
The optical sensor is installed and configured to detect surface cleanliness before significant contamination occurs. The system proactively monitors the contact surface and can trigger cleaning operations or alert users before contamination degrades aerosol generation performance, rather than waiting for performance issues to manifest.
Solution Approach 2:
The optical sensor provides continuous feedback about the cleanliness state of the contact surface to the control system. This feedback loop enables the system to automatically adjust operations, initiate cleaning cycles, or notify users when contamination reaches threshold levels, maintaining optimal performance through real-time monitoring and response.
2Reliability
If the contact surface is monitored for cleanliness, then optimal performance can be maintained, but the device complexity increases due to additional sensors and monitoring systems
Solution Approach 1:
The patent replaces complex mechanical cleaning systems or manual inspection procedures with an optical sensing system. The optical sensor non-contactlessly detects surface cleanliness, eliminating the need for mechanical probes, physical contact during measurement, or manual inspection, thereby reducing mechanical complexity while improving reliability.
Solution Approach 2:
The optical sensor acts as an intermediary between the contact surface and the control system. Instead of direct mechanical contact or complex sensor arrays, the optical field serves as a clean interface that can detect contamination levels without physically interacting with the surface, simplifying the overall system architecture.
