Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If constant power output control is used to heat the liquid substrate, then the heating efficiency is improved, but the temperature control precision deteriorates causing dry burning

Engineering Contradiction:
Improveheating efficiencyVSAvoidtemperature control precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent implements periodic action by dividing the heating process into multiple control cycles, where the controller periodically detects the heating element temperature and adjusts power output in each cycle. This allows the system to maintain high heating efficiency while preventing temperature overshoot that causes dry burning, as the periodic control enables responsive adjustment without sacrificing overall heating performance.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent applies feedback control by continuously detecting the heating element temperature during the heating process and using this information to adjust the power output. The controller receives temperature feedback and dynamically modifies the power supplied to the heating element, ensuring both efficient heating and precise temperature control to avoid dry burning conditions.

Inventive Principle:
Principle #23Feedback

2Productivity

If the heating element temperature is increased to improve aerosol generation speed, then the productivity is improved, but the harmful factors increase due to dry burning

Engineering Contradiction:
Improveaerosol generation speedVSAvoiddry burning
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The feedback control mechanism monitors the heating element temperature in real-time and adjusts power output to maintain optimal heating conditions. This prevents temperature from rising too high and causing dry burning, while still enabling sufficiently high temperatures for efficient aerosol generation, thus resolving the contradiction between productivity and harmful factors.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent dynamically changes the power output parameter based on detected temperature conditions. By adjusting the power parameter in response to temperature feedback, the system maintains temperatures high enough for rapid aerosol generation but below the threshold that causes dry burning, effectively balancing productivity improvement with harm prevention.

Inventive Principle:
Principle #35Parameter changes

AI summary

An electronic atomization apparatus and a control method are provided. The electronic atomization apparatus is controlled by a controller to power a heating element, so that the heating element heats a liquid substrate at a constant target temperature. The controller is configured to periodically and repeatedly perform a control step to control the power provided by a battery cell directly or indirectly to the heating element. The control step includes: determining a preset target temperature; determining, based on a current temperature of the heating element or a difference between the current temperature and the target temperature, power required for the heating element to be heated to the target temperature or maintain the target temperature within a predetermined time period of a single cycle; and controlling the battery cell to directly or indirectly output the required power to the heating element until the predetermined time period ends.
