Rotating Sample Tray for Biochemical Analysis Contamination Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In biochemical analysis apparatuses, users face the risk of sample contamination when replenishing consumables, as they need to extend their hand across sample installation parts, potentially causing samples to adhere to their hands or arms.
Innovation Solution
A biochemical analysis apparatus with a sample tray that can be moved from a normal position to a consumables replenishment position, allowing users to access consumables without crossing over sample installation parts, using an instruction receiving unit and driving control unit to facilitate this movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sample tray is fixed with sample installation parts on the opening part side, then the user can easily access sample installation parts, but the user must extend hand across sample installation parts to access consumables installation parts, causing sample contamination risk
Solution Approach 1:
The sample tray is designed to be rotatable relative to the apparatus body, allowing dynamic repositioning between a first position (sample installation parts facing opening) and a second position (consumables installation parts facing opening). This dynamic adjustment enables the user to access consumables without extending hand across samples, eliminating contamination risk while maintaining ease of operation.
2Object-affected harmful factors
If the sample tray is made rotatable to allow easy access to consumables, then the user can access consumables without crossing sample installation parts, but the device complexity increases
Solution Approach 1:
The sample tray incorporates a simple rotational mechanism with a driving force generation unit that can rotate the tray between two fixed positions. This dynamic design allows the tray to switch between presenting sample installation parts or consumables installation parts to the opening, preventing contamination while adding minimal complexity through a straightforward rotational movement system.
Solution Approach 2:
The system includes a control unit that can automatically control the sample tray rotation, enabling automated repositioning between first and second positions. This self-service capability reduces manual intervention and simplifies operation, offsetting the mechanical complexity through intelligent automation that manages the tray's movement based on operational needs.

AI summary
A sample installation part in which a sample container accommodating a sample to be subjected to biochemical analysis is installed, and consumables installation parts in which consumables to be used for the biochemical analysis are installed are accommodated in an apparatus body of a biochemical analysis apparatus. The apparatus body is provided with an opening part that leads to a sample tray. An instruction receiving unit receives a movement instruction for moving the sample tray from a normal position where the sample installation part is disposed on the opening part side to a consumables replenishment position where the consumables installation parts are disposed on the opening part side. A driving control unit moves the sample tray from the normal position to the consumables replenishment position in a case where the movement instruction is received by the instruction receiving unit.
