1Productivity

If traditional network testing and validation processes are used in industrial facilities, then network performance can be measured, but the process is cumbersome, time-consuming, and lacks automation

Engineering Contradiction:
Improvenetwork testing efficiencyVSAvoidautomation of network testing
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The patent creates a digital twin (virtual copy) of the physical industrial environment including 3D models of facilities, equipment, and wireless signal propagation characteristics. This digital replica enables automated simulation and testing of network performance without requiring physical deployment and manual testing in the actual industrial facility, thereby dramatically improving testing efficiency and automation level

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system performs network performance prediction and validation in advance by simulating various scenarios in the digital twin environment before actual deployment. This preliminary testing allows identification and resolution of potential network issues before they affect real operations, eliminating the need for time-consuming on-site testing and reconfiguration

Inventive Principle:
Principle #10Preliminary action

2Reliability

If physical network deployment is performed in industrial facilities with moving parts and changing layouts, then network coverage can be established, but stability is compromised by environmental changes

Engineering Contradiction:
Improvenetwork stabilityVSAvoidadaptation to changing environment
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system continuously monitors changes in the physical industrial environment (such as moving equipment, changing layouts, new obstructions) and feeds this information back to update the digital twin model. The digital twin then re-simulates network performance to predict how these changes affect coverage and stability, enabling proactive network optimization before actual performance degradation occurs

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The digital twin model is designed to be dynamic rather than static, automatically updating its representation of the industrial environment as changes occur. This dynamic modeling allows the system to adapt to moving parts, changing layouts, and new obstructions, maintaining accurate network performance predictions despite environmental variability

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If comprehensive network validation is performed in physical environments, then accurate performance data can be obtained, but deployment costs increase due to necessary changes and reconfigurations

Engineering Contradiction:
Improvenetwork performance measurement accuracyVSAvoiddeployment cost
Core Design Contradiction:

Solution Approach 1:

By performing all network validation and performance measurement in the digital twin environment rather than physical deployment, the system obtains accurate performance data without incurring the costs of physical installation, testing, and reconfiguration. The digital replica eliminates material costs, equipment deployment costs, and labor costs associated with on-site testing

Inventive Principle:
Principle #26Copying
