Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If aerosol is generated and delivered through a conventional heating system, then aerosol can be produced, but condensation occurs during inhalation reducing aerosol quality

Engineering Contradiction:
Improveaerosol qualityVSAvoidcondensation
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The aerosol distribution column is pre-heated by the inductor coil before aerosol delivery begins. This preliminary heating action ensures that the column maintains sufficient temperature during aerosol flow to prevent condensation, thereby maintaining aerosol quality without requiring continuous high-energy heating during the entire operation cycle.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The inductor coil provides localized heating specifically to the aerosol distribution column where it is most needed to prevent condensation. This targeted approach heats only the critical region (the column) rather than the entire system, improving aerosol quality at the point of delivery while minimizing overall energy consumption and avoiding overheating of other components.

Inventive Principle:
Principle #3Local quality

2Productivity

If heating is applied to generate aerosol, then aerosol production is achieved, but energy consumption increases

Engineering Contradiction:
Improveaerosol generationVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary heating of the aerosol distribution column using the inductor coil before aerosol generation begins. This preliminary action prepares the system for efficient aerosol delivery without requiring continuous high-energy input during the entire operation, thereby reducing overall energy consumption while maintaining productive aerosol generation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The inductor coil enables rapid temperature changes in the aerosol distribution column by adjusting heating parameters. This allows the system to achieve optimal heating temperature quickly for efficient aerosol generation, then reduce or terminate heating when the column is sufficiently warm, changing the thermal parameters dynamically to balance productivity with energy conservation.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If a pilot hole is provided in the plug, then aerosol distribution is improved, but the structure becomes more complex

Engineering Contradiction:
Improveaerosol distributionVSAvoidconsumable structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The consumable is divided into distinct functional segments: the plug with pilot hole, the aerosol generating material, and the filter material. The pilot hole is specifically segmented as a separate feature within the plug structure, allowing it to be formed independently and integrated into the overall consumable assembly. This segmentation simplifies the manufacturing process and assembly while improving aerosol distribution through the dedicated pilot hole pathway.

Inventive Principle:
Principle #1Segmentation
