Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the output power of the cell assembly is increased and the resistance of the heating member is decreased, then the heating efficiency is improved, but the temperature of the heating member becomes excessively high producing harmful substances

Engineering Contradiction:

Improveheating efficiencyVSAvoidharmful substances production

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies feedback control by using a temperature control switch that monitors the temperature of the heating member and automatically adjusts the power supply. When the temperature reaches a preset threshold, the switch cuts off power to prevent overheating and harmful substance generation, while allowing high power operation during normal conditions to maintain heating efficiency.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent changes the resistance parameter of the heating member to an optimal value that balances heating efficiency with temperature control. By carefully selecting the resistance value, the system achieves effective heating while preventing excessive temperature rise that would produce harmful substances.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If the temperature of the heating member is increased to improve atomization, then the vaporization efficiency is improved, but the liquid guiding assembly undergoes carbonization or fragmentation

Engineering Contradiction:

Improvevaporization efficiencyVSAvoidliquid guiding assembly integrity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The temperature control switch provides continuous feedback on the heating member temperature and automatically adjusts power supply to maintain optimal operating temperature. This prevents temperature excursions that would cause carbonization or fragmentation of the liquid guiding assembly while preserving vaporization efficiency during normal operation.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system implements preventive protection by setting the temperature control switch to activate before temperatures reach levels that would damage the liquid guiding assembly. This beforehand cushioning approach prevents carbonization and fragmentation by maintaining a safety margin below critical temperature thresholds.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Object-affected harmful factors

If a temperature control switch is added to prevent overheating, then user safety is improved, but the device complexity increases

Engineering Contradiction:

Improveuser safetyVSAvoiddevice structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The temperature control switch is designed to operate automatically without user intervention. It self-monitors temperature and self-adjusts power supply based on preset thresholds, providing safety protection while requiring minimal additional user interaction or complex control systems.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The feedback mechanism in the temperature control switch provides automatic safety control with minimal added complexity. The switch monitors temperature and automatically adjusts power supply, creating a simple closed-loop control system that enhances user safety without requiring complex electronic controls or multiple components.

Inventive Principle:

Principle #23Feedback
