Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users autonomously fill the aerosol-generation substrate, then the device allows flexible refilling, but the filling amount and quality become uncontrollable and may introduce impurities

Engineering Contradiction:

Improverefilling flexibilityVSAvoidfilling amount and quality control

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The device is divided into separate components: a reusable vaporization device and replaceable aerosol-generation articles. Each article is pre-filled with a specific amount of substrate in a factory-controlled environment, separating the filling operation from user operation. This segmentation allows users to simply replace articles rather than manually refill, maintaining flexibility while ensuring precise control over filling amount and quality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The aerosol-generation substrate is pre-filled into the aerosol-generation article during manufacturing before reaching the user. This preliminary action ensures that the filling amount and quality are controlled in a factory setting with proper equipment, eliminating the need for users to perform imprecise manual filling operations.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If users autonomously fill the aerosol-generation substrate, then the device allows flexible refilling, but impurities may be introduced during filling

Engineering Contradiction:

Improverefilling flexibilityVSAvoidimpurities introduced during filling

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

By separating the substrate filling operation from user interaction, the invention eliminates the harmful effect of user-introduced impurities. The aerosol-generation article is sealed and pre-filled in a controlled manufacturing environment, then replaced by users as a complete unit, preventing contamination during the refilling process.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The aerosol-generation article is designed as a disposable or replaceable component that is pre-filled and sealed. After use, it is discarded and replaced with a new pre-filled article, eliminating the need for user refilling operations that could introduce impurities. This approach prioritizes purity over long-term reusability of the same container.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Ease of repair

If the heating element is separate from the container, then the structure allows easy cleaning and maintenance, but heat transfer efficiency decreases

Engineering Contradiction:

Improvecleaning and maintenanceVSAvoidheat transfer efficiency

Core Design Contradiction:

Ease of repairVSUse of energy by moving object

Solution Approach 1:

The heating element is integrated with the aerosol-generation substrate within the aerosol-generation article, forming a unified component. This merging ensures direct contact between the heating element and substrate, maximizing heat transfer efficiency. The entire article including the heating element is replaced as a unit, maintaining ease of maintenance through simple replacement rather than cleaning.

Inventive Principle:

Principle #5Merging (Combining)
