Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of electrical switchgear systems is complex and prone to errors due to the variety of components and cables, making it difficult to ensure correct connections and monitor the assembly process, especially since existing methods rely on manual wiring and lack reliable automated monitoring.
Innovation Solution
An augmented reality system that automatically identifies components and their intended connections, overlaying connection points on a display image of the switchgear, allowing for real-time monitoring and error detection, enabling correct installation even when components are arranged in a non-predetermined order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual wiring with circuit diagrams is used, then the assembly process can be carried out, but errors increase and assembly time increases
Solution Approach 1:
The patent replaces manual mechanical wiring operations with an automated image recognition and verification system. The camera captures images of connection points, the processing unit automatically identifies them, and the system verifies connections without manual intervention, thereby reducing both errors and assembly time
Solution Approach 2:
The system provides real-time feedback by displaying recognized connection points and verifying actual connections against the circuit diagram. This immediate feedback mechanism allows workers to correct errors promptly and ensures connection accuracy while maintaining efficient assembly pace
2Productivity
If manual wiring is performed, then the assembly can be completed, but the error rate increases
Solution Approach 1:
The patent replaces manual mechanical wiring operations with an automated image recognition and verification system. The camera captures images of connection points, the processing unit automatically identifies them, and the system verifies connections without manual intervention, thereby reducing both errors and assembly time
Solution Approach 2:
The system performs self-verification by automatically capturing images, identifying connection points, and checking whether actual connections match the circuit diagram. This self-service capability ensures connection accuracy while maintaining high assembly efficiency without requiring additional manual checking steps
3Reliability
If automated monitoring is implemented, then connection accuracy improves, but device complexity increases
Solution Approach 1:
The patent replaces complex manual monitoring and verification procedures with a simplified automated system using a camera and image processing unit. This automated monitoring improves connection accuracy while the system remains relatively simple in structure
Solution Approach 2:
The system creates a digital copy (image) of the physical connection points and compares it with the circuit diagram. This copying approach enables automated verification without requiring complex sensing or measurement devices, thus improving reliability while keeping device complexity low
