Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If air is introduced into the insertion space, then aerosol generation is enabled, but air distribution becomes uneven causing poor flow efficiency
Solution Approach 1:
The bottom portion is segmented into a recessed region and a protruding region, creating distinct functional zones. The recessed region serves as a diffusion passage that divides and redirects airflow, while the protruding region provides structural support. This segmentation enables uniform air distribution across the insertion space while maintaining efficient aerosol generation.
Solution Approach 2:
The bottom portion is positioned at a different vertical level (recessed downward) relative to the lower portion of the insertion space, creating a three-dimensional diffusion passage. This dimensional change allows airflow to be redirected and distributed more uniformly across the horizontal plane, solving the uneven air distribution problem while maintaining productivity.
2Productivity
If substances are heated in the insertion space, then aerosol is generated, but substances stick to the device causing fixation
Solution Approach 1:
The harmful effect of substance sticking is extracted and isolated by positioning the bottom portion (which may accumulate substances) in a recessed region separate from the main insertion space. This spatial separation prevents substances from adhering to critical device components while allowing continuous aerosol generation in the protruding region.
3Ease of operation
If the bottom portion is recessed downward, then air flow efficiency is improved, but device complexity increases
Solution Approach 1:
The bottom portion serves multiple functions simultaneously: it provides structural support through its protruding region, creates the diffusion passage for uniform air distribution through its recessed region, and prevents substance accumulation. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving improved air flow efficiency.
