Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a heating wire is used for direct heating and vaporization, then heating efficiency is improved, but the heating component becomes difficult to clean and replace due to direct contact with the aerosol-generation substrate

Engineering Contradiction:

Improveheating efficiencyVSAvoidcleaning and replacement difficulty

Core Design Contradiction:

ProductivityVSEase of repair

Solution Approach 1:

The heating component is divided into separate functional parts: the heating wire remains in the heating body, while the aerosol-generation substrate is separated in a removable container. This segmentation allows the heating wire to maintain direct heating efficiency while the substrate container can be easily removed for cleaning or replacement without disassembling the heating component itself.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The aerosol-generation substrate is extracted from direct contact with the heating wire and placed in a separate removable container. This extraction solves the pollution and cleaning difficulty by allowing the substrate to be taken out and replaced independently, while the heating wire remains in its cleaning-resistant position within the heating body.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If the heating component is electrically connected to the main body through a wire, then electrical connection is established, but installation complexity increases

Engineering Contradiction:

Improveelectrical connectionVSAvoidinstallation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The electrical connection system is replaced with a magnetic field-based heating system. Instead of using wired electrical connections between the heating component and main body, the invention uses a magnetic induction heating element that generates heat through magnetic field induction, eliminating the need for complex wire connections and simplifying installation while maintaining reliable energy transmission.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If the heating wire is in direct and close contact with the aerosol-generation substrate, then heating efficiency is improved, but the heating wire becomes easily polluted

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system is segmented into a heating body containing the heating wire and a separate container holding the aerosol-generation substrate. The heating body can be positioned close to the substrate for efficient heating while the substrate remains in a removable container that can be easily cleaned or replaced, preventing pollution of the heating wire.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The aerosol-generation substrate is extracted into a separate removable container, allowing it to be positioned close to the heating wire for efficient heating while preventing direct contamination of the heating wire. The substrate container can be removed and cleaned separately, eliminating the pollution problem.

Inventive Principle:

Principle #2Taking out (Extraction)
