Compact Sample Inspection Apparatus Using Pneumatic Pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sample inspection apparatuses are large due to the need for manual processes and devices that move pressing members, leading to errors and size constraints in applications like environment monitoring and medical diagnosis.
Innovation Solution
A compact sample inspection apparatus with a 3-way rotatable valve and a fluid supply system that includes a metering chamber and an air pump or manual pump to control fluid flow, allowing precise movement of a pressing member to apply pressure to a cartridge for sample inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a device for moving the pressing member toward the cartridge is used, then the pressing member can be moved to apply pressure to the cartridge, but the size of the sample inspection apparatus cannot be reduced
Solution Approach 1:
The patent uses a fluid supply part that supplies fluid to a fluid storage part, which then transfers fluid to the pressing member to move it toward the cartridge. This pneumatic/hydraulic system replaces traditional mechanical moving devices, enabling compact design while maintaining the ability to apply pressure to the cartridge for sample inspection
2Reliability
If manual processes are used for reagent injecting, mixing, separating and moving, then various inspection processes can be performed, but errors in inspection results occur
Solution Approach 1:
The patent implements an automated system where the fluid supply part automatically supplies fluid to move the pressing member, and the pressing member automatically presses the cartridge to perform sample inspection. This self-service automation eliminates manual operations, thereby reducing human error and improving the reliability of inspection results
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 apparatus achieves a reduced size while maintaining accurate sample inspection by controlling fluid flow and pressure application, reducing errors and enhancing portability in various fields.
Implementation Method 1
a fluid supply part configured to supply the fluid into the fluid storage part
Implementation Method 2
a pressing member disposed in the housing and configured to press the cartridge to inspect the sample, a fluid storage part configured to transfer a fluid to the pressing member so that the pressing member presses the cartridge
