Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the atomizer is measured immediately during contact, then the measurement process is fast, but contact resistance causes deviation in the initial resistance value identification

Engineering Contradiction:
Improveinitial resistance value identification accuracyVSAvoidmeasurement time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by performing multiple resistance value readings at different time points (before atomizer operation, during operation, and after operation) to establish a baseline measurement process that accounts for contact resistance effects, thereby improving initial resistance value identification accuracy

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements periodic action by conducting resistance measurements at regular intervals (first preset time, second preset time, third preset time) to capture resistance variations under different operational conditions, enabling more accurate determination of the initial resistance value by comparing these periodic measurements

Inventive Principle:
Principle #19Periodic action

2Measurement precision

If multiple resistance values are read at different time intervals, then the accuracy of initial resistance measurement is improved, but the measurement process becomes more complex

Engineering Contradiction:
Improveinitial resistance measurement accuracyVSAvoidmeasurement process complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the measurement process into distinct stages (first preset time reading, second preset time reading, third preset time reading) with specific operations at each stage, making the complex multi-step measurement process more manageable and systematic

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements feedback by comparing the resistance values obtained at different time points and using this comparison to determine the initial resistance value, where the measurement process itself provides information that feeds back into the calculation to improve accuracy

Inventive Principle:
Principle #23Feedback

AI summary

This application relates to a resistance measurement method and apparatus for an atomizer, an electronic atomization device, and a storage medium. The method includes: reading a resistance value of the atomizer at intervals of first preset time and obtaining a first preset number of first resistance values; starting the atomizer and continuing for second preset time; reading the resistance value of the atomizer at intervals of third preset time and obtaining a second preset number of second resistance values; and calculating an average value of the first resistance values and the second resistance values as an initial resistance value of the atomizer. Through this method, the accuracy of the initial resistance value measurement of the atomizer can be improved.
