Solution Overview

Problem

Existing control parameter adjustment methods for servomotors in complex operations are time-consuming and require specialized knowledge to prepare appropriate operation commands, making it difficult for individuals without experience to adjust control parameters effectively.

Innovation Solution

A control parameter adjustment device and method that utilizes actual process operation information to generate adjustment operation commands, incorporating state information to adjust servomotor parameters without prior preparation of operation commands, through a system comprising an actual process operation information obtainer, adjustment operation command generator, controller, state information obtainer, and control parameter adjuster.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the servomotor performs a relatively complicated operation in the actual process workflow, then the operation can complete the required task, but the control parameter adjustment takes too much time and does not finish within a practical time frame

Engineering Contradiction:

Improvecontrol parameter adjustment completenessVSAvoidcontrol parameter adjustment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary analysis of the operation command to identify candidate control parameters before actual adjustment begins. This preliminary action allows the system to prepare adjustment strategies in advance, reducing the time required during actual parameter tuning while ensuring comprehensive coverage of necessary parameters.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The control parameter adjustment process is divided into multiple stages: candidate parameter identification, priority determination, and sequential adjustment. This segmentation allows the system to handle complicated operations by breaking down the adjustment process into manageable segments that can be completed efficiently within practical time frames.

Inventive Principle:

Principle #1Segmentation

2Productivity

If an appropriate operation command is prepared for control parameter adjustment, then the adjustment can be completed efficiently, but it requires accumulation of know-how and is difficult for persons without experience

Engineering Contradiction:

Improvecontrol parameter adjustment efficiencyVSAvoidoperation command preparation difficulty

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system automatically generates candidate control parameters and determines adjustment priorities based on the operation command itself, without requiring external expertise. The servomotor control device performs self-analysis and self-adjustment, making the process accessible to operators without specialized knowledge while maintaining high efficiency.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses feedback from the operation command analysis to automatically determine which control parameters need adjustment and in what order. This feedback mechanism replaces the need for human expertise in command preparation, allowing the system to self-optimize based on the specific operation requirements.

Inventive Principle:

Principle #23Feedback

3Ease of operation

If the system uses the actual process workflow operation command for control parameter adjustment, then no separate command preparation is needed, but the adjustment takes too much time due to the complexity of the operation

Engineering Contradiction:

Improveoperation command preparation simplicityVSAvoidcontrol parameter adjustment time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary analysis of the operation command to identify candidate control parameters and their priorities before actual adjustment begins. This preliminary processing of the actual workflow command allows the system to maintain simplicity in operation while reducing adjustment time by pre-identifying necessary parameters.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The adjustment process is segmented into candidate identification, priority determination, and execution phases. This allows the system to use the actual workflow command without being overwhelmed by its complexity, as each segment handles a specific aspect of the adjustment process efficiently.

Inventive Principle:

Principle #1Segmentation
