Rotating Reagent Container Rows for High-Throughput Specimen Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for treating prepared specimens suffer from low throughput due to long transport times and the risk of reagent contamination, with complex control mechanisms required to prevent collisions and contamination.
Innovation Solution
The apparatus features parallel container rows with a rotation unit and a transport mechanism that allows for movement along multiple axes, including a Z-axis, enabling shorter transport distances and preventing reagent contamination by allowing reagents to drip off before reaching other containers, with a drip pan system to collect any spills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple transport mechanisms are used to increase throughput, then productivity improves, but device complexity increases and collision risk increases
Solution Approach 1:
The apparatus is divided into multiple independent treatment modules, each with its own reagent containers and transport access. Multiple transport mechanisms operate in separate spatial zones within the apparatus, allowing parallel processing of specimens without requiring complex coordination between mechanisms. Each module can be independently controlled, reducing overall system complexity while maintaining high throughput.
2Adaptability or versatility
If reagent containers are arranged in matrix structure, then all reagents are accessible, but transport distance increases and transport time increases
Solution Approach 1:
The reagent containers are arranged in a three-dimensional configuration with multiple levels or tiers rather than a flat two-dimensional matrix. This vertical arrangement allows transport mechanisms to access reagents through multiple spatial dimensions, reducing the horizontal travel distance required while still providing access to all reagent containers. The Z-axis movement capability enables efficient navigation through the 3D reagent array.
3Productivity
If transport mechanism speed is increased to reduce transport time, then productivity improves, but collision risk increases and control complexity increases
Solution Approach 1:
The transport system is segmented into multiple independent mechanisms operating in distinct spatial zones. Each transport mechanism operates at optimized speeds within its designated area, avoiding the need for one high-speed mechanism that would require complex collision avoidance systems. The segmentation allows parallel high-speed operation without interference between mechanisms.
4Ease of operation
If transport container travels over reagent containers, then reagent access is efficient, but reagent contamination occurs
Solution Approach 1:
The transport container is extracted from the path over reagent containers. Instead of traveling horizontally over the reagent array, the transport mechanism retrieves the transport container vertically or through an alternative route that bypasses the reagent containers entirely. This eliminates the contamination risk from droplets falling onto reagents while maintaining efficient access to all reagent containers through the 3D arrangement.

Implementation Method 1
the container rows are received rotatably at the ends of the holding arms of the at least one holding element that is connected to a rotation shaft such that it co-rotates with the rotation shaft
Implementation Method 2
Gravity causes the formation of droplets that, as the transport container or carrier travels over the reagent containers, drip off and into the reagent containers being traveled over
Implementation Method 3
a drip pan system to collect any spills
