Sample Analyzer Disposal Box Integration for Light Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample analyzing devices suffer from reduced analysis accuracy due to external light interference and improper disposal of pipette tips, which causes noise and obstructs the photodetector, leading to inefficient measurement processes.
Innovation Solution
The device incorporates a disposal box integrated with the holder, allowing for internal disposal via a door, eliminating the need for a drawer structure, and features separate disposal spaces with an arc-shaped opening to prevent pipette tip obstruction, along with a detection mechanism to ensure the disposal box is properly set, and a rotating holder for efficient container switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a drawer structure is provided for drawing the disposal box, then the disposal box can be easily accessed, but external light enters through gaps and causes noise to the photodetector
Solution Approach 1:
The disposal box is extracted from the main body structure and integrated with the holder, allowing it to be removed together with the holder via the door rather than requiring a separate drawer structure. This eliminates the drawer-related light gaps while maintaining disposal box accessibility.
Solution Approach 2:
The disposal box is merged with the holder structure, forming an integrated assembly. This combination allows the disposal box to be accessed through holder removal via the door, eliminating the need for a separate drawer structure that would create light leakage paths.
2Ease of operation
If the drawer structure is used for disposal box access, then disposal is convenient, but the structure complexity increases and light shielding is compromised
Solution Approach 1:
The disposal box is merged with the holder structure, forming an integrated assembly. This combination eliminates the need for a separate drawer structure, reducing device complexity while maintaining disposal box accessibility through holder removal.
Solution Approach 2:
The holder structure serves dual functions: holding containers for measurement and housing the disposal box. This multi-functionality eliminates the need for separate drawer structures, reducing overall device complexity.
3Volume of stationary object
If pipette tips are disposed of in a single space, then the disposal box is compact, but tips become obstructive and cause step-out problems
Solution Approach 1:
The disposal box is segmented into multiple disposal spaces within its structure. This segmentation allows pipette tips to be disposed of in separate compartments, preventing them from becoming obstructive while maintaining a compact overall disposal box size.
4Productivity
If the holder holds multiple containers, then measurement efficiency improves, but the frequency of door opening increases
Solution Approach 1:
The disposal box is merged with the holder structure, allowing both containers and disposal box to be removed together via a single door operation. This reduces the frequency of door opening compared to separate access structures.
