Stopper Securing Motion Monitoring for Container Seal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing pharmaceutical or medical containers with stoppers and closure lids fail to ensure high tightness, allowing contaminants to potentially contact the contents, and lack effective monitoring for quality assurance during the securing process.
Innovation Solution
A method that involves detecting and measuring the relative movement between the container and the closure lid during securing, using sensors to determine the quality of motion transmission and detect any deviations from predetermined specifications, thereby ensuring proper sealing and preventing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional securing methods are used without monitoring, then the securing process is simple and fast, but the tightness and sealing quality cannot be ensured, allowing contaminants to contact the contents
Solution Approach 1:
The patent implements feedback by detecting the relative movement between container and closure lid during securing and comparing it against predetermined reference values. This feedback mechanism enables real-time quality monitoring to ensure proper sealing while maintaining an efficient process flow.
Solution Approach 2:
The patent replaces complex mechanical monitoring systems with a sensor-based detection approach that measures relative movement between components. This substitution simplifies the overall system while providing reliable quality assurance through electronic sensing and data comparison.
2Measurement precision
If visual tests are used for quality checking, then the equipment is simple, but the detection is time-consuming and may miss deviations
Solution Approach 1:
The patent replaces manual visual inspection with automated sensor-based detection that measures relative movement between the container and closure lid. This substitution enables precise, rapid quality assessment that does not slow down the securing process.
Solution Approach 2:
The system performs self-verification by automatically comparing detected movement values against reference values and identifying deviations without requiring external inspection. This autonomous quality check maintains high speed while ensuring accuracy.
3Reliability
If no monitoring of motion transmission is carried out, then the process is fast and simple, but deviations in securing quality go undetected
Solution Approach 1:
The patent establishes a feedback loop that continuously monitors the relative movement between container and closure lid during securing. By comparing actual movement against reference values, the system automatically detects quality deviations and enables corrective action.
Solution Approach 2:
The patent introduces a sensor as an intermediary element that indirectly measures the quality of securing by detecting relative movement. This intermediary approach simplifies measurement while providing reliable quality data without requiring direct observation of the sealing interface.

AI summary
According to the invention, in a method for securing a stopper on a container with a closure lid using a securing station, it is proposed that measurements of quantities, in particular movement quantities, around an axis are carried out during the securing process to assess the securing process and that the recorded measured values are evaluated to detect insufficiently secured containers.
