Endotoxin Measuring Device With Vertical Component Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measuring devices for endotoxin detection are bulky due to the horizontal arrangement of tip well housings and well plates, leading to increased device size.
Innovation Solution
A measuring device design with a vertical arrangement of components, including a measurement part, tool placement area, dispensing part, and housing that accommodates these elements, along with a movable tray and non-overlapping dilution plate placement, allowing for miniaturization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If tip well housings and well plates are arranged horizontally, then the device structure is simple and easy to manufacture, but the device size increases
Solution Approach 1:
The patent transitions from horizontal arrangement to vertical stacking of measurement components (tip well housing, well plate, measurement chamber) along the height direction. This dimensional change allows the device to maintain functional simplicity while reducing horizontal footprint, directly resolving the contradiction between ease of manufacture and device size.
2Ease of operation
If multiple components are arranged horizontally, then each component can be independently accessed, but the overall device becomes bulky
Solution Approach 1:
The patent implements a nested vertical arrangement where the tip well housing, measurement chamber, and well plate are stacked one above another in a compact configuration. This nesting approach allows all components to be accessed through the top opening while minimizing horizontal space, resolving the contradiction between accessibility and device volume.
3Adaptability or versatility
If the dispensing part is made movable, then liquid distribution flexibility is improved, but device complexity increases
Solution Approach 1:
The dispensing part is designed with movable capability to adjust position and orientation, enabling flexible liquid distribution to different wells. This dynamic element provides adaptability for various measurement configurations while the movement mechanism is integrated into the existing vertical stacking structure, minimizing additional complexity.
