Container Stopper Securing with Slip Detection for Closure Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pharmaceutical or medical containers are challenging to secure effectively, as existing methods fail to ensure high tightness and prevent contamination, with issues like slip between components affecting the quality of the securing process.
Innovation Solution
A method that involves detecting and measuring the relative movement between a container and its closure cover, using sensors to monitor the synchronous rotational movement and slip, allowing for real-time assessment of the securing quality and preventing non-sufficient closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional securing methods are used for pharmaceutical containers, then the securing process is simple, but the tightness and contamination prevention are insufficient
Solution Approach 1:
The patent implements feedback by detecting the relative movement between container and closure cover during securing and comparing it with a reference value. This feedback mechanism allows the system to monitor whether the securing process achieved the desired tightness and contamination prevention, enabling real-time quality control without fundamentally changing the securing method itself.
Solution Approach 2:
The patent replaces purely mechanical securing methods with a hybrid system that incorporates sensing technology. By using sensors to detect relative movement and compare with reference values, the system substitutes mechanical trial-and-error with measurement-based verification, improving reliability while adding moderate complexity through the sensing system.
2Manufacturing precision
If no movement detection is performed during securing, then the process is fast and simple, but the quality of securing cannot be monitored
Solution Approach 1:
The patent uses feedback by continuously monitoring the relative movement between container and closure cover during the securing process and comparing it with a pre-established reference value. This allows real-time assessment of securing quality without requiring complex measurement systems, as the reference value serves as a simple comparison benchmark.
Solution Approach 2:
The system performs self-verification by using the relative movement detection itself to determine securing quality. The measured movement data directly serves as the quality indicator, eliminating the need for separate complex inspection procedures. The reference value acts as an internal standard that the system uses to self-assess its own performance.
3Manufacturing precision
If relative movement detection is implemented during securing, then securing quality can be monitored, but the process time increases
Solution Approach 1:
The patent maintains continuity by performing the movement detection throughout the entire securing process rather than adding separate inspection steps. The detection occurs continuously during securing, allowing quality monitoring without interrupting or extending the overall process time, thus maintaining productivity while achieving manufacturing precision.

AI summary
A method for securing a stopper on a container using a closure cover with the aid of a securing station, in which, during the securing, carries out measurements of quantities, in particular movement quantities, about an axis in order to assess the securing operation, and the detected measured values are assessed in order to detect insufficiently secured containers.
