Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing immune analyzers face challenges in reducing the size of the cleaning device while maintaining effective cleaning efficiency, as increasing the number of reaction vessels on the turntable necessitates a longer magnetic adsorption component, leading to a larger device footprint.
Innovation Solution
A turntable mechanism with concentrically arranged placement part groups and through hole groups, allowing for the dispersal of reaction vessels across multiple circles, thereby reducing the time for each vessel to pass through the magnetic adsorption component without increasing its length, thus maintaining cleaning efficiency in a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the length of the magnetic adsorption component is increased to maintain cleaning effect, then the cleaning effectiveness is improved, but the size and occupied space of the cleaning device increases
Solution Approach 1:
The patent transitions from a single-circle arrangement to a multi-circle concentric arrangement of reaction vessels on the turntable. This dimensional change allows multiple vessels to be processed simultaneously at different radial positions, reducing the required length of the magnetic adsorption component while maintaining cleaning effectiveness through parallel processing.
Solution Approach 2:
The turntable is divided into multiple circles of placement part groups, with each circle containing multiple placement parts arranged at intervals along the circumferential direction. This segmentation allows different reaction vessels to be at different stages of the cleaning process simultaneously, reducing the required processing length.
2Productivity
If the number of reaction vessels on the turntable is increased to improve throughput, then the productivity is improved, but the magnetic adsorption component length must be increased leading to larger device size
Solution Approach 1:
The patent uses a multi-circle concentric arrangement where reaction vessels are distributed across multiple circles rather than a single circle. This allows more vessels to be accommodated on the same turntable area, increasing throughput without requiring a longer magnetic adsorption component, as vessels in different circles can be processed in parallel.
Solution Approach 2:
The placement parts are segmented into multiple circles with through hole groups formed between adjacent circles. This segmentation enables multiple reaction vessels to undergo magnetic adsorption and cleaning simultaneously at different radial positions, improving productivity while keeping the magnetic adsorption component length compact.
3Productivity
If the turntable rotation speed is increased to reduce stop time and improve cleaning speed, then the productivity is improved, but the time for reaction vessel to pass through magnetic adsorption component decreases compromising cleaning effect
Solution Approach 1:
The turntable is segmented into multiple circles of placement part groups, allowing reaction vessels to be distributed across different radial positions. This enables the turntable to rotate faster while vessels in different circles still receive adequate exposure to the magnetic adsorption component, maintaining cleaning effect while improving overall cleaning speed through parallel processing.
Solution Approach 2:
The multi-circle arrangement allows for continuous processing where reaction vessels move through different stages of cleaning simultaneously. The turntable can maintain higher rotation speeds while ensuring each vessel receives the necessary processing time at each station, as vessels are continuously fed through the system in parallel streams.
