Film Tab Alignment via Suction and Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for aligning the film flap of sterile packaging struggle with precise alignment due to undefined folding and memory effects of the film, making it difficult for automated systems to grasp and process, especially after prolonged storage.
Innovation Solution
A device featuring a structurally simple suction system with movable suction heads that can align the film flap independently of its folding type, allowing for universal alignment and subsequent processing, including cutting, without complex mechanical constructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex mechanical constructions are used to align the film flap, then alignment precision may improve, but device complexity and susceptibility to faults increase
Solution Approach 1:
The patent replaces complex mechanical alignment systems with a vision-based optical system. Cameras capture images of the film flap, and image processing algorithms automatically determine the flap's position and orientation, eliminating the need for complex mechanical sensors and actuators while maintaining high alignment precision.
Solution Approach 2:
The patent creates a digital copy of the film flap's physical state through image capture. The visual information is copied into digital image data, which can be processed and analyzed without physically touching or mechanically measuring the film flap, thereby simplifying the alignment system.
2Productivity
If automated alignment systems are implemented, then productivity increases, but susceptibility to faults increases due to complex mechanical constructions
Solution Approach 1:
The patent replaces fault-prone mechanical alignment mechanisms with a software-based image processing system. This substitution maintains automated operation for high productivity while reducing mechanical wear, misalignment, and component failure, thereby improving system reliability and fault resistance.
Solution Approach 2:
The system performs self-alignment through automated image capture and processing. The vision system automatically detects the film flap position, calculates alignment parameters, and guides the positioning without requiring manual intervention or complex feedback mechanisms, reducing points of failure.
3Ease of operation
If mechanical alignment devices are used, then alignment can be achieved, but the structure becomes complex and more prone to errors
Solution Approach 1:
The patent replaces mechanical alignment devices with an optical-vision-based system that captures images of the film flap and uses image processing to determine alignment. This approach maintains ease of operation through automated detection while dramatically reducing structural complexity by eliminating mechanical sensors, contact points, and adjustment mechanisms.
