Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual mapping is performed by maintenance workers walking through the installation and copying ID numbers, then a map of PV module locations can be obtained, but the process is time-consuming and prone to human error

Engineering Contradiction:
Improveaccuracy of module location informationVSAvoidtime required for mapping
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical mapping processes with automated optical and electronic systems. A scanning device with camera captures images of PV modules and automatically reads ID numbers, eliminating the need for manual copying of information. The system uses image processing algorithms to extract and recognize module identifiers, substituting human visual inspection and manual data entry with automated computer vision technology.

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

Solution Approach 2:

The PV modules themselves provide their identification information through machine-readable codes (barcodes, QR codes, or printed ID numbers) that can be automatically scanned and read. The modules essentially serve themselves by displaying their unique identifiers in a format that the scanning device can automatically capture and process, eliminating the need for external manual data collection.

Inventive Principle:
Principle #25Self-service

2Reliability

If manual mapping is performed to locate specific malfunctioning modules, then location information can be obtained, but human error causes inaccurate information to be recorded

Engineering Contradiction:
Improveaccuracy of recorded module informationVSAvoidefficiency of troubleshooting
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces manual data collection and recording processes with automated optical scanning and digital image processing. The scanning device captures images of PV modules and uses computer vision algorithms to automatically read and record ID numbers, eliminating human error in data transcription. The system digitally stores and processes module identification information without manual intervention, ensuring accurate and reliable data recording.

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

Solution Approach 2:

The system provides visual feedback by displaying captured module images and recognized ID numbers on a screen, allowing operators to verify the accuracy of automatic recognition. The feedback mechanism enables real-time validation of the mapping data, ensuring that the automatically captured information is accurate before final recording.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If operators physically locate malfunctioning modules without accurate maps, then troubleshooting can be performed, but the process becomes time-consuming

Engineering Contradiction:
Improveease of locating malfunctioning modulesVSAvoidtime for troubleshooting
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent creates a digital copy or replica of the physical PV installation layout through automated scanning and mapping. The system generates a virtual map that mirrors the actual physical arrangement of modules, allowing operators to view module locations and identification information on a screen without physically navigating to each module. This digital copy enables rapid location of malfunctioning modules through visual inspection of the mapped data.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent transitions from two-dimensional physical location searching to three-dimensional virtual space navigation. By creating a digital map that includes spatial coordinates and module positions, the system allows operators to locate malfunctioning modules in a virtual representation of the installation, reducing the need for physical traversal and enabling faster troubleshooting through digital interface interaction.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
