Innovation Solution
A system utilizing machine-identifiable indicia, a camera, and a programmable logic controller (PLC) to verify physical connections between source and destination locations, reducing susceptibility to environmental disturbances and enhancing reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If human operators perform visual inspection to verify connections, then the system is simple and low-cost, but the reliability is reduced due to human error
Solution Approach 1:
The patent replaces the mechanical/visual inspection system with an optical detection system. A camera captures images of connection points, and an image processing system automatically analyzes whether connections are properly made, substituting human visual inspection with automated optical-mechanical systems to eliminate human error while maintaining operational simplicity
Solution Approach 2:
The verification system performs self-checking by automatically capturing images, processing them, and determining connection status without requiring human intervention. The system serves itself by autonomously verifying connections and providing feedback, eliminating the need for operators to perform manual visual inspections
2Reliability
If electrical signals or RFID are used for verification, then the reliability is improved, but the system becomes susceptible to interference from static electricity and radio frequency
Solution Approach 1:
The patent substitutes electrical and electromagnetic verification methods with an optical-based verification system. By using cameras and image processing to detect connection status through visual fields rather than electrical signals, the system eliminates susceptibility to static electricity interference and radio frequency interference while maintaining high reliability
Solution Approach 2:
The patent introduces light as an intermediary medium for verification. Instead of using electrical signals that are susceptible to interference, the system uses optical fields (light) as the intermediary to carry information about connection status from the connection points to the detection system, providing immunity to electrical and electromagnetic interference
3Measurement precision
If electrical or RFID verification devices are implemented, then the measurement precision is improved, but the cost of implementation and maintenance becomes prohibitive
Solution Approach 1:
The patent employs inexpensive camera components and standard image processing software instead of costly specialized electrical or RFID verification devices. The system uses readily available, low-cost optical components that can be easily manufactured and replaced, significantly reducing implementation and maintenance costs while maintaining measurement precision through software-based analysis
Data Source
AI summary
Manufacturing and industrial processes that involve the transfer of materials from source locations to destination location may utilize the presently described system and process to verify that the correct physical connections are established and maintained in a material handling system. The system collects information related to individual physical connections, including machine-identifiable indicia, and compares this information to data that defines the intended connections within the material handling system. In doing so, the system and process verify whether the proper physical connections are in place.
