Analysis Container Liquid Air Passage Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional analysis containers cannot maintain a sealed state while allowing liquid specimens to move between chambers, which is necessary for genetic analysis to prevent contamination and ensure accurate processing.
Innovation Solution
The analysis container features a liquid passage and an air passage connecting chambers, enabling the movement of liquid specimens between chambers while maintaining a sealed state by balancing air volume changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If air holes are provided in chambers to enable liquid specimen flow between chambers, then liquid movement is facilitated, but sealed state cannot be maintained
Solution Approach 1:
The patent divides the passage system into two separate independent passages: a liquid passage for liquid specimen flow and an air passage for air movement. This segmentation allows each passage to perform its specific function without interfering with the sealed state, resolving the contradiction between enabling liquid flow and maintaining sealing.
Solution Approach 2:
The air passage acts as an intermediary mechanism that enables liquid movement by allowing air to move in response to liquid displacement, while maintaining the sealed state. The air passage mediates between the liquid passage and the external environment, permitting internal pressure equalization without compromising the seal.
2Reliability
If the analysis container is sealed to prevent contamination, then reliability is improved, but liquid specimen cannot move between chambers
Solution Approach 1:
By segmenting the passage system into liquid and air passages, the patent enables liquid specimen movement between chambers while maintaining the sealed state. The liquid passage allows controlled liquid flow, while the air passage maintains pressure balance, together resolving the contradiction between sealing and liquid movement.
Solution Approach 2:
The patent utilizes pneumatic principles by introducing an air passage that allows air to move in response to liquid displacement. This pneumatic mechanism enables liquid flow through pressure differential created by air movement, all while maintaining the sealed container state, thus resolving the contradiction between sealing and liquid movement.
3Ease of operation
If air holes are provided for liquid movement, then liquid flow is enabled, but amplified products can be released
Solution Approach 1:
The patent segments the passage system into liquid and air passages, where the air passage is specifically designed to allow air movement while the liquid passage handles liquid flow. This segmentation ensures that amplified products remain contained in the liquid phase while air can move freely to enable liquid transport, preventing product release.
Solution Approach 2:
The air passage serves as an intermediary that enables liquid flow without direct exposure to the external environment. By mediating the pressure balance through controlled air movement, the system allows liquid transport while maintaining the sealed state that prevents amplified product release.
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
This configuration allows for accurate and sealed movement of liquid specimens between chambers, preventing contamination and ensuring effective genetic analysis, even when the container is sealed.
Implementation Method 1
The liquid specimen flows from chamber to chamber provided in the analysis container, through passages, and in a predetermined order, under the surface tension attributable to capillary action exerted on the passages
Implementation Method 2
The air passage connects the first chamber and the second chamber and moves air from the second chamber to the first chamber

AI summary
An analysis container comprises a main body; a first chamber that is provided inside the main body and holds a liquid sample; a second chamber; a liquid passage; and an air passage. The liquid passage connects the first chamber and the second chamber, and moves the liquid sample from the first chamber to the second chamber. The air flow chamber connects the first chamber and the second chamber, and moves air from the second chamber to the first chamber.
