Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure support systems face challenges in increasing liquid capacity in humidifiers, which enhances user convenience but increases power consumption, initialization time, and humidity adjustment time.
Innovation Solution
A pressure support system with a humidifier design that includes a humidification chamber, a heating element, and a partition, where the humidification chamber is pressurized by gas flow, reducing the liquid level within it while maintaining a higher level in a separate holding chamber, allowing efficient liquid communication and reduced power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the liquid capacity in the humidifier is increased, then the convenience for users is improved, but the power consumption increases
Solution Approach 1:
The humidifier is divided into two separate chambers: a holding chamber for storing liquid and a humidification chamber for active humidification. This segmentation allows the system to maintain a large total liquid capacity while only heating the smaller volume in the humidification chamber, thus improving convenience without proportionally increasing power consumption.
Solution Approach 2:
The holding chamber pre-stores liquid that can be quickly transferred to the humidification chamber when needed. This preliminary preparation allows the system to respond rapidly to humidity adjustments without needing to heat large volumes of liquid, reducing power consumption while maintaining operational convenience.
2Ease of operation
If the liquid capacity in the humidifier is increased, then the convenience for users is improved, but the initialization time increases
Solution Approach 1:
By segmenting the humidifier into holding and humidification chambers, the system can maintain a large total liquid capacity in the holding chamber while keeping the humidification chamber volume small. This allows rapid heating and initialization of the humidification chamber without the delay of heating a large volume, thus improving convenience without increasing initialization time.
3Ease of operation
If the liquid capacity in the humidifier is increased, then the convenience for users is improved, but the time to adjust humidity levels increases
Solution Approach 1:
The segmentation into holding and humidification chambers enables the system to maintain large liquid storage while keeping the active humidification volume small. When humidity adjustments are needed, only the liquid in the humidification chamber needs to be heated, allowing rapid adjustment of humidity levels while maintaining overall liquid capacity for user convenience.
Solution Approach 2:
The holding chamber maintains a ready supply of liquid that can be quickly transferred to the humidification chamber. This preliminary preparation ensures that when humidity adjustments are required, the system can rapidly respond by heating only the necessary small volume in the humidification chamber, improving adjustment speed while maintaining convenience.
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 design allows for enhanced liquid storage capacity without increasing power consumption or initialization time, enabling faster and more efficient humidity adjustments in the gas flow.
Implementation Method 1
The heating element is configured to controllably elevate the temperature of fluid within the humidification chamber to heat liquid within humidification chamber such that the gas flowing through the humidification chamber from the gas inlet to the gas outlet is humidified by the heated liquid
Implementation Method 2
the partition and liquid held in the humidification chamber isolate the flow path formed by humidification chamber from the holding chamber causing the flow of gas through the humidification chamber to result in pressurization of the humidification chamber that reduces the level of liquid within the humidification chamber

AI summary
A pressure support system configured to provide pressure support therapy includes a humidifier that holds an enhanced amount of liquid while enhancing the power consumption of the pressure support system and enabling relatively rapid adjustments to humidity level. The humidifier includes a humidification chamber and a holding chamber, and a partition that divides the holding chamber from the humidification chamber such that liquid from the holding chamber replenishes liquid held in the humidification chamber. The partition, however, also provides a level of thermal isolation for the humidification chamber from the holding chamber.
