Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a steel tube with an oval shaped aperture is used to allow liquid flow onto the heating unit, then the liquid flow path is simple, but the liquid concentration becomes uneven along the heating unit
Solution Approach 1:
The heating element is segmented into multiple functional components: a wire mesh heating unit with multiple inlets, each inlet having separate top-slit and bottom-slit portions. This segmentation allows independent control and optimization of liquid distribution at different locations, ensuring uniform liquid concentration across the entire heating surface while maintaining structural simplicity.
2Device complexity
If the liquid is not evenly distributed along the heating element, then the structure is simple, but the vaporization quality deteriorates with liquid droplets in inhalate
Solution Approach 1:
The inlet structure implements local quality by providing separate top-slit and bottom-slit portions at each inlet location, allowing optimized liquid distribution tailored to specific local requirements. This ensures that liquid is evenly distributed across different regions of the heating element, preventing liquid droplet formation in the inhalate while maintaining a relatively simple overall device structure.
3Device complexity
If the heating element does not evenly distribute heat, then the construction is simple, but the atomization quality deteriorates with vapor particles of different volumes
Solution Approach 1:
The wire mesh heating element changes the physical parameters of heat distribution by providing multiple heating zones corresponding to different inlet positions. This allows independent temperature control and optimization at each location, ensuring uniform heat distribution across the heating surface and producing consistent vapor particle volumes, while maintaining simple construction.
4Reliability
If liquid is vaporized too finely, then the vaporization is thorough, but the flavor of the inhalant is diluted
Solution Approach 1:
The heating element design incorporates feedback mechanisms through its multi-inlet wire mesh structure, where liquid distribution and heat application are coordinated to achieve optimal vaporization. This controlled vaporization process ensures complete atomization for thorough vaporization while maintaining appropriate vapor particle sizes that preserve flavor concentration, preventing both liquid droplet inhalation and excessive flavor dilution.
