Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the heater temperature is increased to improve aerosol generation efficiency, then the flavor quality and user experience improve, but the risk of overheating and moisture evaporation control becomes difficult

Engineering Contradiction:

Improveaerosol generation efficiencyVSAvoidtemperature control stability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The heating process is divided into multiple distinct periods: a first period from initial temperature to first temperature, and a second period from first temperature to second temperature. This segmentation allows different temperature control strategies to be applied to different stages of heating, improving both efficiency and stability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The controller pre-determines the time length of the second period based on the initial temperature of the heater before heating begins. This preliminary action allows the system to optimize the entire heating profile in advance, ensuring that the heater reaches optimal temperatures for aerosol generation while maintaining control stability.

Inventive Principle:

Principle #10Preliminary action

2Manufacturing precision

If the pre-heating time is extended to ensure complete moisture evaporation, then flavor quality improves, but the time delay before aerosol generation begins increases

Engineering Contradiction:

Improveflavor delivery qualityVSAvoidpre-heating time delay

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The controller dynamically adjusts the time length of the second period based on the initial temperature parameter. When the initial temperature is higher, the time length is shortened; when lower, it is extended. This parameter-based adaptation optimizes both flavor quality and response time for each heating scenario.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The heating control system transitions from static fixed-time pre-heating to dynamic adaptive pre-heating, where the duration of the second period is determined by the actual initial temperature conditions. This dynamic approach allows the system to achieve complete moisture evaporation while minimizing unnecessary delays.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If multiple temperature control phases are implemented to improve user experience, then aerosol generation quality improves, but the control system complexity increases

Engineering Contradiction:

Improveuser experience qualityVSAvoidcontrol system structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The controller automatically determines the time length of the second period based on the initial temperature without requiring user input or manual adjustment. The system self-regulates the heating profile, providing complex multi-phase temperature control while maintaining simple operation for the user.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The controller uses the initial temperature of the heater as feedback to automatically adjust the heating profile. By measuring the initial state and adapting the second period duration accordingly, the system achieves sophisticated temperature control with minimal user involvement and simplified operation.
