Innovation Solution

An electronic smoking device with a pump mechanism that allows the base liquid from the reservoir to be squirted directly onto the heating element in a fully assembled state, eliminating the need for manual disassembly and simplifying the liquid application process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If manual disassembly and pipette application is used to apply liquid directly to the heating element, then vapor production is improved and taste is intensified, but device complexity and ease of operation deteriorate

Engineering Contradiction:
Improvevapor productionVSAvoidease of liquid application
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The invention extracts the liquid application function from the manual disassembly process by providing a dedicated liquid application mechanism integrated into the device. This allows liquid to be applied directly to the heating element through a simplified interface without requiring users to disassemble the device or use external pipettes, thereby maintaining improved vapor production while significantly enhancing ease of operation

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The device performs liquid application automatically through its integrated mechanism, eliminating the need for manual intervention with external tools. The system serves itself by providing a built-in solution that automatically handles liquid delivery to the heating element, improving both ease of operation and consistency of liquid application

Inventive Principle:
Principle #25Self-service

2Quantity of substance

If manual disassembly is used to apply liquid directly to the heating element, then vapor production is improved, but time consumption increases

Engineering Contradiction:
Improvevapor productionVSAvoidtime for liquid application
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The liquid application mechanism is pre-integrated into the device structure, with the liquid application path and delivery system prepared in advance. This eliminates the need for time-consuming manual disassembly and pipette application during use, allowing users to quickly apply liquid through a simple interface while maintaining the vapor production benefits of direct liquid application

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If pump mechanism is added to squirt liquid directly onto heating element, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of liquid applicationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention merges the liquid storage reservoir, liquid delivery path, and heating element into an integrated assembly. The pump mechanism is combined with these components to form a unified liquid application system, reducing the need for separate external tools and simplifying the overall device structure while improving ease of operation

Inventive Principle:
Principle #5Merging (Combining)
