Transparent Receptacle Imaging for Plastic Container Crack Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for testing plastic containers' mechanical strength are inadequate as they do not allow precise determination of the origin and propagation of cracks, nor do they provide real-time monitoring, leading to disparate results and inability to correlate crack initiation with explosion moments.
Innovation Solution
A device with a transparent receptacle and image acquisition means for capturing images of the container under pressure, allowing for real-time monitoring of cracks and explosions, along with a high-speed camera and computer processing for detailed analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional testing methods are used to assess container mechanical strength, then the testing process is simple, but the ability to determine crack origin and propagation is insufficient
Solution Approach 1:
The patent replaces conventional mechanical testing methods with an optical imaging system. Image acquisition means capture visual records of the container bottom during pressurization, allowing crack detection through optical analysis rather than mechanical measurement, thereby achieving precise crack origin and propagation tracking without complex mechanical sensing apparatus
Solution Approach 2:
The patent introduces a transparent receptacle filled with liquid solution as an intermediary medium. This receptacle allows light transmission to the image acquisition means while containing the container during pressurization testing, enabling visual monitoring of crack development without direct mechanical contact that would interfere with the testing process
2Loss of time
If real-time monitoring of container degradation is implemented, then crack propagation can be tracked, but the device becomes more complex
Solution Approach 1:
The patent implements continuous image acquisition during the pressurization process. The image acquisition means continuously capture the container bottom state as pressure increases, enabling real-time tracking of crack initiation and propagation without interrupting the testing process, thereby reducing time loss while maintaining manageable system complexity through a single integrated imaging system
Solution Approach 2:
The patent creates visual copies of the container bottom through image acquisition. By capturing multiple images at different pressure stages, the system creates a temporal sequence of visual records that track degradation processes, allowing real-time monitoring without requiring complex sensor arrays or intrusive measurement systems
3Reliability
If containers are subjected to high internal pressure to simulate service conditions, then safety can be assessed, but the risk of explosion increases
Solution Approach 1:
The patent uses a transparent receptacle filled with liquid solution as an intermediary containment system. This receptacle holds the pressurized container during testing, allowing visual monitoring of crack development under high pressure conditions while providing a controlled environment that manages explosion risk through the receptacle's containment capability
Solution Approach 2:
The patent implements real-time visual feedback through continuous image acquisition during pressurization. The system monitors the container bottom for crack formation and propagation as pressure increases, allowing operators to observe degradation processes and stop testing before catastrophic failure, thereby assessing safety while managing explosion risk through active monitoring and controlled test termination
