Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automatic control method is used to simplify operation, then ease of operation is improved, but control accuracy deteriorates because it merely replicates user settings without considering whether the control is proper

Engineering Contradiction:
Improveoperation simplicityVSAvoidcontrol accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system collects user adjustment operations during air conditioner running, counts the adjustment frequency, and uses this feedback to determine whether to store operational parameters as optimal. When adjustment frequency exceeds a threshold, the parameters are not stored, ensuring only truly optimal parameters are saved for automatic control.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system automatically learns and stores optimal operational parameters by observing user adjustment behaviors. The control unit self-updates the optimal parameter database based on accumulated running data and adjustment frequency analysis, eliminating the need for manual re-programming by users.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If user manually adjusts operational parameters to adapt to changing environment, then control accuracy is improved, but ease of operation deteriorates due to complicated and time-consuming modifications

Engineering Contradiction:
Improvecontrol accuracyVSAvoidoperation simplicity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system pre-stores optimal operational parameters for various ambient temperatures based on historical running data and user adjustment patterns. When the air conditioner starts, it automatically selects the most suitable pre-stored parameters according to current ambient temperature, avoiding the need for manual adjustments.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically changes the stored optimal parameters based on ambient temperature conditions. By categorizing parameters according to temperature ranges and automatically selecting appropriate sets, the system adapts to environmental changes without requiring user intervention.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If optimal operational parameters are stored for all ambient temperatures, then adaptability is improved, but device complexity increases due to data storage and selection requirements

Engineering Contradiction:
Improvetemperature adaptationVSAvoiddata storage complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments optimal parameters into different sets categorized by ambient temperature ranges. Instead of storing all possible parameters uniformly, it divides them into temperature-specific groups, simplifying the storage structure and selection process while maintaining comprehensive adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary categorization of operational parameters according to ambient temperature conditions during the data storage phase. This pre-organization enables efficient retrieval and automatic selection based on current temperature, reducing the computational complexity during operation.

Inventive Principle:
Principle #10Preliminary action

4Adaptability or versatility

If frequent adjustments of operational parameters are allowed during running, then adaptability is improved, but loss of time increases due to repeated modifications

Engineering Contradiction:
Improveparameter flexibilityVSAvoidadjustment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system monitors and counts the number of user adjustments during each running cycle. When the adjustment count exceeds a predetermined threshold, the system determines that the parameters should not be stored as optimal, preventing future unnecessary adjustments and saving time.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary validation of operational parameters by analyzing user adjustment behavior before storing them. This pre-screening ensures that only stable, optimal parameters are stored, preventing future frequent adjustments and reducing time loss.

Inventive Principle:
Principle #10Preliminary action

AI summary

An air conditioner control method includes: obtaining a current ambient temperature when the air conditioner is being powered on, and selecting a current operational parameter corresponding to the current ambient temperature from stored optimal operational parameters which are paired with historical ambient temperatures; performing a control process on the air conditioner according to the current operational parameter; wherein a one-to-one correspondence between the historical ambient temperatures and the optimal operational parameters obtained by a process including: obtaining a continuous running time since this start, how many times operational parameters being modified since this start and a ambient temperature since this start as receiving a power-off signal; obtaining an allowed modification times of operational parameters during the running duration, which corresponds to the continuous running time since this start, if the times of the operational parameters being modified obtained is not greater than the allowed modification times, pairing the optimal operational parameter with the ambient temperature to generate and store the one-to-one correspondence between the optimal operational parameters and the historical ambient temperatures; if the times of the operational parameters being modified obtained is greater than the allowed modification times identified, terminating the setting of the optimal operational parameters. This method could improve the accuracy of air conditioner control and make the user feel more comfortable.
