Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current manual line clearance processes in packaging equipment lines are inefficient, prone to human error, and often fail to detect residual products from previous runs, posing risks to end users.
Innovation Solution
An automated system utilizing image capturing devices installed along the packaging line to compare end run images with control images, generating difference images and inspection reports to ensure thorough line clearance, reducing the time and effort required for inspection and improving detection accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inspection processes are used for line clearance, then inspection can be conducted without additional equipment, but inspection time and effort increase significantly and detection accuracy decreases
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated image-based inspection system. Image capturing devices automatically capture images of the packaging line, and image processing algorithms automatically analyze these images to detect residual products, eliminating the need for manual visual inspection and significantly improving both speed and accuracy.
Solution Approach 2:
The patent creates visual copies (images) of the packaging line using image capturing devices. These images serve as digital representations that can be analyzed without physically inspecting the line, allowing for rapid and repeatable inspection that doesn't require manual intervention.
2Reliability
If manual inspection is performed in difficult-to-access areas, then inspection coverage can be achieved, but inspection efficiency decreases and human error increases
Solution Approach 1:
The automated image-based system eliminates the need for inspectors to physically access difficult-to-reach areas. Image capturing devices positioned at strategic locations automatically capture images of all inspection areas including hidden or hard-to-access regions, maintaining comprehensive coverage while dramatically improving efficiency and eliminating human error associated with manual inspection.
Solution Approach 2:
The patent transitions from two-dimensional manual visual inspection to multi-dimensional automated image capture and analysis. The system captures images from multiple angles and perspectives, processes them through algorithms that can detect patterns and anomalies beyond human capability, and provides comprehensive inspection coverage of all line areas including those difficult to access manually.
3Productivity
If image capturing devices are installed throughout the packaging line, then detection accuracy and inspection speed improve, but system complexity and installation cost increase
Solution Approach 1:
The patent employs image capturing devices that serve multiple functions: capturing images of the packaging line, providing visual records for quality documentation, and enabling both rapid inspection and detailed analysis when needed. This multi-functionality justifies the installation investment and reduces overall system complexity by consolidating inspection capabilities into versatile devices.
Solution Approach 2:
The inspection system is designed to be self-sufficient, with image capturing devices automatically capturing images and image processing algorithms automatically analyzing them without requiring constant human intervention. The system performs self-calibration and self-validation, reducing operational complexity and allowing local engineering and quality control staff to easily operate and maintain the system.
