Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the optical detector is positioned inside the heating chamber to detect codes on the aerosol carrier, then the detection can be performed during heating operation, but the detector becomes soiled and affected by heat leading to unreliable detection
Solution Approach 1:
The device is divided into two distinct spatial zones: the heating chamber for thermal processing and the code detection zone outside the chamber. This segmentation allows the optical detector to operate in a clean, cool environment while the heating chamber performs its function independently, eliminating the harmful effects of heat and dirt on the detector.
Solution Approach 2:
The optical detection function is extracted from the heating chamber environment and positioned outside the chamber. The detector is placed in a separate location where it can read codes on the aerosol carrier without being exposed to the high temperature and contaminant-laden atmosphere inside the heating chamber.
2Adaptability or versatility
If a mirror is added to the cavity to expand the field of view for code detection, then the detection coverage is improved, but the device size increases and the mirror surface becomes soiled
Solution Approach 1:
The mirror component is completely removed from the system. Instead of using optical reflection elements inside the cavity, the detector is positioned outside the heating chamber to directly view the code on the aerosol carrier, eliminating the need for mirrors and their associated problems of soiling and space requirements.
Solution Approach 2:
The detection approach moves from a two-dimensional planar detection within the cavity to a three-dimensional external detection position. By placing the detector outside the chamber and utilizing the vertical or lateral space external to the heating chamber, the system achieves adequate code viewing angles without requiring internal mirror arrangements.
3Measurement precision
If the detector is positioned to read codes inside the heating chamber, then authentication can be performed, but the detector is exposed to heat that affects its performance and durability
Solution Approach 1:
The system is segmented into thermal processing zone (heating chamber) and detection zone (outside chamber). This spatial segmentation ensures the detector operates at ambient temperature while the heating chamber maintains its high temperature for aerosol generation, preventing thermal interference with the optical detection system.
Solution Approach 2:
The aerosol carrier itself serves as an intermediary, carrying both the code information and the material to be heated. The detector reads the code on the carrier's external surface before or during insertion, without needing to be positioned in the hot zone. The carrier acts as the medium that connects the detection function and the heating function without requiring direct spatial overlap of the detector and heat source.
