Filter Element Orientation Correction in Pipette Tip Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Filter elements, especially multicomponent filters, are often incorrectly aligned when transferred for further processing, such as insertion into pipette tips, due to varying alignments during separation and handling.
Innovation Solution
A method and device that identify incorrectly aligned single elements or filter elements, eject them from receiving pockets, turn them by 180°, and reinsert them into the correct alignment using a position recognition system and turning mechanism, such as a rotatable turning cylinder with suction and blowing pressure, to ensure proper alignment before further processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If filter elements are transferred in bulk material form through receiving bores, then the handling process is simple and fast, but the alignment of filter elements becomes incorrect and varies
Solution Approach 1:
The patent applies preliminary action by introducing a pre-alignment station before the final insertion process. At this station, filter elements are examined and realigned to the correct orientation before being transferred to pipette tips, ensuring proper alignment without compromising handling speed
Solution Approach 2:
The patent uses an intermediary alignment station as a mediator between the bulk transfer system and the final insertion process. This intermediate stage allows for correction of alignment issues without disrupting the overall high-speed handling workflow
2Manufacturing precision
If a position recognition system and turning mechanism are added to correct alignment, then alignment accuracy is improved, but device complexity increases
Solution Approach 1:
The patent segments the alignment correction function into modular components: a position recognition system that identifies misaligned elements, and a turning mechanism that corrects their orientation. This segmentation allows each component to be optimized independently and simplifies the overall system architecture
Solution Approach 2:
The alignment system operates autonomously by automatically detecting misaligned filter elements through the position recognition system and correcting them via the turning mechanism without requiring manual intervention, thereby managing the increased complexity through automation
