1Productivity

If traditional parameter optimization method is used (one process parameter output at a time with sequential measurement), then the method is simple to implement, but the time consumption and iteration count increase significantly

Engineering Contradiction:
Improveoptimization efficiencyVSAvoidtime consumption
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent segments the parameter optimization process into distinct functional modules: data acquisition module for collecting input-output pairs, sampling function calculation module for generating candidate parameters, clustering module for grouping similar parameters, and recommendation module for selecting optimal parameters. This segmentation enables parallel processing of multiple parameters simultaneously, dramatically reducing iteration time and improving optimization efficiency compared to sequential methods.

2Manufacturing precision

If multiple iterations are performed to achieve process target value, then the optimization accuracy improves, but the number of measurement batches increases

Engineering Contradiction:
Improveprocess target achievementVSAvoidmeasurement batch efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent performs preliminary actions by pre-calculating sampling function values for multiple candidate parameters before actual measurement. The sampling function calculation module generates probability distributions and identifies promising parameter ranges in advance, allowing the system to prioritize which parameters to measure first. This preliminary analysis reduces the number of measurement batches needed to achieve the process target value, as measurements are strategically directed toward most promising candidates rather than random or sequential exploration.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms where measurement results from previous iterations are fed back into the clustering and recommendation modules. The system continuously updates parameter groups based on observed outcomes, refining its understanding of the input-output relationship. This feedback loop enables the recommendation module to progressively identify optimal parameters with fewer iterations, improving both manufacturing precision and measurement efficiency by learning from each measurement batch.

Inventive Principle:
Principle #23Feedback
