Tissue Treating Apparatus Gas Exchange via Pump Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tissue piece treating apparatuses face challenges in promoting drying inside the treating tank due to weak gas exchange actions, and there is a risk of inflammation from insufficient gas discharge.
Innovation Solution
The apparatus includes a treating tank, a communication passage with an outside air port, and a pump that pressurizes and decompresses the tank, allowing outside air to be supplied and gas to be discharged, enhancing gas exchange and discharge actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pump is used only for pressurizing and decompressing the treating tank during chemical solution transport, then the pump structure remains simple, but the gas exchange action is weak and drying is insufficient
Solution Approach 1:
The communication passage is designed to serve multiple functions: it enables chemical solution transport between the treating tank and chemical solution bottles, provides an outside air port for gas exchange during drying, and allows pressure control. This multi-functionality resolves the contradiction by making the existing structure more versatile rather than adding separate dedicated components for drying.
2Productivity
If the pump operates with weak gas exchange action, then the system operates safely with minimal gas discharge, but the drying treatment is insufficient inside the treating tank
Solution Approach 1:
The outside air port acts as an intermediary channel that facilitates gas exchange between the treating tank interior and the external environment. By providing this dedicated gas exchange pathway, alcohol vapors can be discharged safely during drying, reducing inflammation risk while enabling faster drying through enhanced gas circulation.
3Reliability
If the treating tank is sealed tightly for chemical solution containment, then chemical solution leakage is prevented, but gas exchange and drying are hindered
Solution Approach 1:
The communication passage system is segmented into different functional zones: sealed sections for chemical solution containment and a controlled opening (outside air port) for gas exchange. This segmentation allows the system to maintain chemical solution containment integrity while providing a dedicated pathway for gas exchange during drying operations.
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 promotes drying inside the treating tank by enhancing gas exchange and prevents the risk of inflammation by improving gas discharge, compared to conventional systems.
Implementation Method 1
a pump that causes an inside of the treating tank to be a negative pressure to supply the chemical solution from the chemical solution bottle to the inside of the treating tank, and causes the inside of the treating tank to be a positive pressure to discharge the chemical solution from the inside of the treating tank
Implementation Method 2
the communication passage includes, by partially branching, an outside air port that communicates with an outside air, and is thus configured to be able to supply and discharge the outside air to and from the inside of the treating tank
Implementation Method 3
the gas exchange action by the pump is an action for merely attaining the purpose of pressurizing and decompressing the inside of the treating tank, and thus has been relatively weak. Accordingly, the gas exchange action does not sufficiently act on the drying in the inside of the treating tank
