Container Membrane Tightness Testing via Segmented Deforming Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for testing the tightness of containers closed by membranes are inefficient in handling multiple containers simultaneously and ensuring uniformity of the deforming force, which affects the precision and reliability of detecting defects such as small openings or tears.
Innovation Solution
The apparatus comprises a deforming unit with multiple deforming devices, each associated with a single container, allowing for independent application of a uniform deforming action. This setup ensures that the deforming force is applied consistently across all containers, enhancing the precision and reliability of the tightness testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single deforming device is used to test multiple containers sequentially, then the device complexity is reduced, but the productivity decreases due to slower testing speed
Solution Approach 1:
The testing system is divided into multiple independent deforming devices, each responsible for testing one container. This segmentation allows parallel processing of multiple containers, significantly increasing productivity while maintaining manageable complexity through modular design
2Manufacturing precision
If a single deforming device handles multiple containers, then the device complexity is lower, but the manufacturing precision of deforming force application deteriorates due to inability to ensure uniformity
Solution Approach 1:
By assigning a dedicated deforming device to each container, the system ensures that each container receives a uniform and controlled deforming force. This one-to-one correspondence eliminates variability in force application that would occur with shared devices
Solution Approach 2:
Each deforming device is optimized to apply the precise deforming force required for its specific container, ensuring local uniformity of force application. This localized optimization guarantees consistent testing conditions across all containers
3Measurement precision
If deforming action is applied to multiple containers simultaneously using shared devices, then the productivity increases, but the measurement precision deteriorates due to lack of independent control
Solution Approach 1:
The system segments the testing function into independent deforming devices, each capable of simultaneous operation on its assigned container. This segmentation enables parallel testing while maintaining independent measurement precision for each container

Function Achieved in This Case
The solution enables precise and reliable detection of defects in the containers, ensuring that containers with even small openings or tears can be identified, thereby maintaining the integrity of the packaging and preventing contamination or oxidation of the contents.
Implementation Method 1
submitting the container to a deforming action by compression, for example by a localised squeezing
Implementation Method 2
Thanks to this deforming action, the pressure level inside the container is increased when referred to a tightly closed container
