Solution Overview

Problem

Analyzing trace data from equipment related to motor control is complex and prone to errors due to the current manual transmission process, which involves users sending data to operators and then to manufacturers, leading to potential mistakes and increased complexity in handling user inquiries.

Innovation Solution

A trace data recording system that automatically generates, transmits, and records trace data to a cloud server, linking it with alarm information and user/equipment identification, allowing for easy analysis by analysts without manual intervention, and providing relevant data only when an alarm is generated or upon request.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual transmission process is used for trace data, then users can send data to operators and manufacturers, but handling complexity and error probability increase

Engineering Contradiction:
Improvedata transmission accuracyVSAvoidhandling process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The equipment performs self-diagnosis and automatically transmits trace data to the server when an alarm occurs, eliminating the need for manual data collection and transmission by users. The system serves itself by detecting failures and initiating data transmission autonomously.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical process of users copying and sending data is replaced by an automated electronic transmission system. The trace data transmitting unit automatically sends data via network communication, substituting the manual mechanical handling process with an automated electronic system.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If all trace data is transmitted to server, then complete analysis information is available, but data transmission time and network bandwidth are consumed

Engineering Contradiction:
Improvetrace data completenessVSAvoiddata transmission time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

Only the necessary trace data related to the alarm is extracted and transmitted to the server. The system identifies and sends only the relevant data portions required for analyzing the specific alarm condition, rather than transmitting all accumulated trace data.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system transmits a partial set of trace data that is sufficient for alarm analysis rather than the complete data set. By transmitting only the necessary portion of data related to the alarm event, the system achieves adequate analysis information with reduced transmission overhead.

Inventive Principle:
Principle #16Partial or excessive action

3Productivity

If automatic trace data transmission is implemented, then analysis speed improves, but system complexity increases

Engineering Contradiction:
Improveanalysis speedVSAvoidsystem structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The control unit performs multiple functions: it monitors equipment operation, detects alarm conditions, generates alarm information, and triggers trace data transmission. By consolidating these functions in a single control unit, the system achieves automatic rapid transmission without proportionally increasing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The alarm information generation and trace data transmission functions are merged into an integrated automated process. When an alarm is detected, the system combines the alarm data with relevant trace data and transmits them together as a single package, streamlining the overall system architecture.

Inventive Principle:
Principle #5Merging (Combining)
