Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If automated detection is implemented without user interaction, then detection speed is improved, but detection accuracy deteriorates due to false alarms

Engineering Contradiction:
Improvedetection speedVSAvoiddetection accuracy
Core Design Contradiction:
SpeedVSMeasurement precision

Solution Approach 1:

The system implements a feedback mechanism where detection results are sent to users for confirmation. When an abnormality is detected, the system queries the user to verify whether the detected issue truly exists, creating a closed-loop feedback system that improves detection accuracy while maintaining automated operation

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables users to self-verify detection results through simple interactions. Users can confirm or deny detected abnormalities through straightforward queries, allowing the system to leverage user knowledge for verification without requiring complex manual inspection procedures

Inventive Principle:
Principle #25Self-service

2Measurement precision

If complex troubleshooting procedures are implemented, then abnormality resolution accuracy is improved, but operation complexity increases

Engineering Contradiction:
Improveabnormality resolution accuracyVSAvoidoperation complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The troubleshooting process is segmented into multiple simple interaction steps rather than presenting users with complex procedures all at once. The system divides abnormality resolution into sequential queries and actions, making each step manageable and reducing perceived complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The troubleshooting procedure dynamically adapts based on user responses. The system adjusts subsequent queries and actions according to the specific abnormality confirmed by the user, creating a flexible rather than rigid process that simplifies operation while maintaining accuracy

Inventive Principle:
Principle #15Dynamics

3Device complexity

If static detection models are used, then system simplicity is maintained, but detection accuracy deteriorates over time

Engineering Contradiction:
Improvesystem simplicityVSAvoiddetection accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The system collects detection data and user feedback in advance to build training datasets. This preliminary data accumulation enables subsequent model optimization without requiring immediate system redesign, allowing accuracy improvement while maintaining operational simplicity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The detection model parameters are optimized based on collected data, transforming the static model into an adaptable one. By changing model parameters rather than restructuring the entire system, the patent achieves accuracy improvement while preserving system simplicity

Inventive Principle:
Principle #35Parameter changes

AI summary

The present disclosure provides a photovoltaic (PV) equipment safety detection method and a PV equipment safety detection system. The method includes: performing status detection on a PV power station; determining whether there is an abnormality according to detection information, outputting an abnormality instruction if there is an abnormality, and parsing and processing the abnormality instruction to generate an inquiry instruction; displaying the inquiry instruction to a user, and providing, by the user, reply information; determining, according to the reply information, whether to send a further inquiry instruction to the user for an inquiry, or to send an execution instruction to the PV power station, such that according to the execution instruction, the PV power station performs an action to resolve the abnormality or conducts self-inspection and reports the abnormality; and feeding the execution instruction back to a preprocessing port, and performing model switching or model self-learning according to the execution instruction, thereby performing iterative upgrading to obtain an accurate detection result. Through effective iterative interactions with the user, a false alarm caused by the environmental condition is avoided, thereby improving the abnormality handling efficiency, saving human and material resources, reducing operation and maintenance costs, and effectively enhancing user experience.
