Image Capturing Device for Industrial Printer Print Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current industrial printer systems rely on real-time communication between the printer and image capturing device to verify print information, which is limited by information transfer speed and prone to network delays and faults, making them less reliable for ensuring accurate and complete print verification.
Innovation Solution
The image capturing device dynamically determines part of the print information, allowing it to compute and verify the print data independently, eliminating the need for real-time communication with the printer and enhancing reliability by synchronizing with the printer's dynamic data computation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time communication is used between printer and image capturing device for print verification, then the system can verify print information, but the reliability is limited by information transfer speed and network delays
Solution Approach 1:
The image capturing device preliminarily determines the dynamic print information using the same algorithm as the printer before the actual printing occurs. This advance determination allows the device to have the verification data ready, eliminating the need for real-time communication during the critical verification window and thus improving reliability while reducing time loss.
Solution Approach 2:
The image capturing device creates a local copy of the dynamic print information by independently computing it using the same algorithm that the printer uses. This copying approach eliminates dependency on real-time communication for data transfer, as the verification device now has its own copy of the data to compare against the actual print output.
2Reliability
If real-time communication is used between printer and image capturing device, then print information can be transmitted, but the system is prone to network delays and faults
Solution Approach 1:
The invention extracts the dynamic print information determination function from the communication system and places it locally in the image capturing device. By taking out the computation capability and implementing it independently at the verification device, the system eliminates the need for complex real-time communication infrastructure while improving reliability.
Solution Approach 2:
The image capturing device serves itself by independently determining the dynamic print information it needs for verification purposes. Instead of relying on the printer to provide the data through communication channels, the verification device performs the determination autonomously using the same algorithm, thus making the system self-sufficient and reducing communication dependencies.
3Reliability
If the image capturing device determines dynamic print information independently, then real-time communication is eliminated, but the device must have computation capability
Solution Approach 1:
The image capturing device is designed with multi-functionality, combining both the image capture capability and the dynamic print information determination capability in a single device. This universal approach eliminates the need for separate communication infrastructure and reduces overall system complexity, making the device more versatile while improving reliability.
