Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple tubular heaters are spaced apart and independently started to heat different sections, then heating control flexibility is improved, but device complexity increases

Engineering Contradiction:
Improveheating control flexibilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The heater is divided into multiple heating sections (first, second, and third heating sections) that are sequentially arranged along the longitudinal direction. Each heating section can be independently controlled through separate control circuits, allowing flexible heating profiles for different sections of the aerosol generation product without requiring multiple separate heater assemblies.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control circuit dynamically adjusts the power distribution to different heating sections based on real-time temperature feedback from temperature sensors. The system can switch between different heating modes (sequential heating, simultaneous heating, variable power heating) to optimize aerosol generation while maintaining simplified hardware architecture.

Inventive Principle:
Principle #15Dynamics

2Productivity

If heating power is increased to generate aerosol faster, then productivity is improved, but temperature control precision deteriorates

Engineering Contradiction:
Improveaerosol generation speedVSAvoidtemperature control precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The control circuit implements periodic heating cycles with multiple stages: initial high-power heating to rapidly raise temperature and generate aerosol, followed by reduced-power maintenance heating to sustain aerosol generation. The system can switch between different heating sections in sequence, providing periodic thermal action that maintains productivity while preventing overheating and ensuring precise temperature control.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

Temperature sensors are positioned to detect temperatures at different heating sections, and the control circuit uses this feedback information to dynamically adjust power distribution. When a section reaches the target temperature, the control circuit reduces or stops power to that section while maintaining or increasing power to other sections, ensuring precise temperature control throughout the aerosol generation process.

Inventive Principle:
Principle #23Feedback

3Loss of energy

If sequential heating of different sections is implemented, then energy efficiency is improved, but heating time increases

Engineering Contradiction:
Improveenergy efficiencyVSAvoidheating time
Core Design Contradiction:
Loss of energyVSLoss of time

Solution Approach 1:

The control circuit pre-heats sections that are closer to the aerosol generation zone first, while simultaneously or subsequently activating other sections. This preliminary action ensures that when the aerosol generation product is inserted, the critical heating sections are already at optimal temperature, reducing overall heating time while maintaining energy efficiency by avoiding unnecessary heating of non-critical sections.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous useful heating action by switching between different heating sections without interruption. While one section is being heated or maintaining temperature, another section is being activated or is already contributing to aerosol generation. This continuous operation eliminates idle time and ensures that energy is constantly being used productively across different sections.

Inventive Principle:
Principle #20Continuity of useful action
