Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If wider apertures are used in the aerosol generating component, then aerosol production increases, but leakage of aerosolizable material increases

Engineering Contradiction:

Improveaerosol productionVSAvoidleakage of aerosolizable material

Core Design Contradiction:

ProductivityVSLoss of substance

Solution Approach 1:

The patent applies local quality by differentiating the aperture dimensions in different regions of the aerosol generating component. The first apertures have a first width optimized for aerosol generation, while the second apertures have a second width specifically controlled to prevent leakage. This spatial differentiation of aperture properties allows simultaneous optimization of aerosol production and prevention of material loss.

Inventive Principle:

Principle #3Local quality

2Loss of substance

If narrower apertures are used in the aerosol generating component, then leakage is reduced, but heat distribution becomes inconsistent

Engineering Contradiction:

Improveleakage reductionVSAvoidheat distribution consistency

Core Design Contradiction:

Loss of substanceVSStability of the object's composition

Solution Approach 1:

The patent resolves this contradiction by assigning different aperture widths to different functional zones. The first apertures are configured with a first width that facilitates consistent heat distribution and aerosol generation, while the second apertures have a narrower second width that prevents leakage. This localized differentiation allows each region to optimize for its specific function.

Inventive Principle:

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent segments the aerosol generating component into multiple aperture sets with different width characteristics. The first apertures have a first width optimized for aerosol generation and heat distribution, while the second apertures have a second width optimized for preventing leakage. This segmentation allows precise control over aerosol characteristics while maintaining manufacturing feasibility through standardized aperture formation processes.
