Perpendicular Pore Chip Case for Air Pocket Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air pockets form in the pore of a pore chip during measurement, blocking the flow of solution and particles, which is difficult to remove and can damage the membrane with ultrasonic cleaning, and plasma treatment is time-consuming and costly.
Innovation Solution
A pore chip case is designed to support the pore chip in a perpendicular plane with chambers that elevate the liquid level, preventing air pockets and increasing water pressure, thereby improving particle transmission and measurement efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ultrasonic cleaning is used to remove air pockets, then air pockets can be removed, but the membrane may be damaged
Solution Approach 1:
The pore chip case is designed with a specific structure that prevents air pockets from forming in the first place by ensuring proper filling order and orientation, eliminating the need for subsequent ultrasonic cleaning that could damage the membrane
2Reliability
If plasma treatment is used to prevent air pockets, then air pocket formation is suppressed, but the process becomes time-consuming and costly
Solution Approach 1:
The pore chip case structure itself serves the function of preventing air pockets through its geometric design and filling mechanism, eliminating the need for external plasma treatment processes
Solution Approach 2:
The invention uses a simple structural design in the pore chip case that is cost-effective to manufacture and does not require expensive plasma treatment equipment or additional processing steps
3Device complexity
If the pore chip is placed horizontally, then the structure is simple, but air pockets form in the pore blocking solution flow
Solution Approach 1:
The invention changes the orientation dimension by placing the pore chip vertically in the perpendicular plane, and uses chamber design to elevate liquid level, preventing air pockets while maintaining structural simplicity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The structure allows for efficient particle detection by suppressing air pockets, increasing water pressure, and reducing measurement time by half compared to prior methods.
Implementation Method 1
chambers that elevate the liquid level, preventing air pockets and increasing water pressure
Implementation Method 2
Under potential difference generated between the electrode 106 and the electrode 108, an ion current flows between the electrodes, during which the particles 4 migrate from one chamber through the pore 104 into the other chamber while driven by electrophoresis
Implementation Method 3
During passage of each particle through the pore, the electrolyte solution in the pore will decrease the volume by an amount equivalent to the volume of the particle, thus increasing electric resistance of the pore. The volume (or, particle size) of the particle can therefore be determined, by measuring the electric resistance of the pore

AI summary
A pore chip case houses a pore chip. A main body includes a chip housing space, a first chamber, and a second chamber. The pore chip is housed in the chip housing space and is supported in a perpendicular plane. The first chamber and the second chamber adjoin in the horizontal direction and are partitioned by the pore chip.
