Reagent Rack Lid Layout for Unobstructed Analyzer Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lids of reagent vessels in existing automatic analyzers can interfere with the dispensing of reagents, either by being excessively open and covering adjacent openings or insufficiently open and obstructing the path of the reagent dispensing unit.
Innovation Solution
The automatic analyzer incorporates a reagent rack with a lid opening unit that opens lids along the direction of reagent vessel arrangement and a lid fixing unit that maintains the lids in an open state outside the path of the reagent dispensing unit, ensuring unobstructed reagent dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid is opened to allow reagent dispensing, then the reagent can be accessed by the dispensing unit, but the lid may interfere with dispensing by covering adjacent openings or the dispensing path
Solution Approach 1:
The lid is extracted from its traditional position above the reagent vessel opening and relocated to the side of the vessel. This extraction removes the lid from the dispensing path, eliminating the interference problem while maintaining reagent access capability.
Solution Approach 2:
The lid opening direction is changed from vertical (upward) to horizontal (lateral). By opening the lid in another dimension perpendicular to the dispensing path, the lid no longer obstructs the vertical movement of the dispensing unit while still providing access to the reagent.
2Reliability
If the lid is kept closed to prevent contamination, then reagent stability is maintained, but the reagent dispensing unit cannot access the reagent
Solution Approach 1:
The lid is opened in advance before the dispensing operation begins and remains in the opened position throughout the dispensing process. This preliminary action ensures that the reagent is accessible when needed while the lid mechanism maintains it in a stable, controlled state.
Solution Approach 2:
The lid transitions from a static closed state to a dynamic opened state, allowing the system to switch between protection mode and dispensing mode. The lid can be opened when dispensing is required and provides a stable open position during the operation.

AI summary
Provided is an automatic analyzer in which a lid of a reagent vessel does not hinder the dispensing of the reagent.An automatic analyzer for analyzing a specimen includes a reagent dispensing unit for dispensing a reagent from a reagent bottle in which a plurality of reagent vessels storing reagents used for the analysis of the specimen are arranged in one direction, and a reagent rack in which reagent bottles are stored, in which the reagent rack includes a lid opening unit for opening a lid corresponding to an upward opening of the reagent vessel along an arrangement direction of the reagent vessels, and a lid fixing unit for fixing the lid to the outside of a path in which the reagent dispensing unit is inserted into the opening.
