Isolated Airflow Passage for Pet ICU Oxygen Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pet ICU air conditioning systems are not isolated from the outside environment, leading to unpredictable oxygen concentrations, which can hinder effective care for injured or sick pets.
Innovation Solution
An air adjusting device comprising a casing, hood, airflow generating unit, tunnel, and air conditioning module, forming an isolated airflow passage that draws and conditions ambient air within the enclosed chamber, maintaining specific oxygen concentrations by isolating the internal space from external air exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the air conditioning system is not isolated from the outside environment, then the system structure is simple and easy to implement, but the oxygen concentration inside the enclosed chamber cannot be maintained at a specific level
Solution Approach 1:
The air conditioning system is divided into two separate systems: an isolated air conditioning system that operates within the enclosed chamber to maintain oxygen concentration, and an external air conditioning system that handles external air exchange. This segmentation allows the internal oxygen environment to be controlled independently from external air exchange requirements
Solution Approach 2:
The air inlet and air outlet of the air conditioning system are extracted from the enclosed chamber space and positioned outside the chamber. The air conditioning module draws air from outside the chamber and discharges air outside the chamber, preventing air exchange that would affect internal oxygen concentration while maintaining the chamber's sealed environment
2Reliability
If the enclosed chamber is isolated from the outside environment, then oxygen concentration can be maintained, but the system complexity increases due to isolation requirements
Solution Approach 1:
The air conditioning module is merged with the enclosed chamber structure, where the air conditioning system's air inlet and outlet are integrated into the chamber's external surfaces. This merging allows the isolation function to be achieved through structural integration rather than adding separate isolation components, reducing overall system complexity while maintaining reliable oxygen concentration control

AI summary
An air adjusting device includes a casing, a hood, a first airflow generating unit, a tunnel and an air conditioning module. The hood has a wind inlet. The first airflow generating unit is connected to the hood. The tunnel is connected to the first airflow generating unit, wherein the tunnel has a wind outlet. The hood, the first airflow generating unit and the tunnel form an airflow passage. The airflow passage is isolated from an internal space of the casing. At least one part of the air conditioning module is disposed at the wind inlet. The first airflow generating unit draws a first ambient air into the airflow passage from the wind inlet. A temperature of the first ambient air is adjusted by the air conditioning module and discharged from the wind outlet through the airflow passage.
