Modular CPAP Humidifier Layout for Portable Overnight Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CPAP apparatuses with humidification functions are bulky and hinder portability, making them inconvenient for users who need to travel or stay away from home overnight.
Innovation Solution
A modular CPAP design comprising a body unit with an air-sending device and a base unit with a humidifier, allowing the apparatus to be used in a combined state for humidified air delivery at home and a separated state for portable use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a humidifier is integrated into the CPAP apparatus, then the humidification function is improved, but the size and weight of the apparatus increase, reducing portability
Solution Approach 1:
The CPAP apparatus is divided into two separate units: a body unit containing the air-sending device and a base unit containing the humidifier. This segmentation allows the humidifier to be included in the complete apparatus while enabling portability by using only the lighter body unit when traveling, thus resolving the contradiction between having a humidification function and maintaining portability.

3Weight of moving object
If the CPAP apparatus is designed for portability, then the size and weight are reduced, but the humidification function is lost
Solution Approach 1:
The system dynamically adapts its configuration based on usage scenario. The body unit can operate independently for portable use without humidification, or connect to the base unit when humidification is needed. This dynamic configurability allows the apparatus to maintain minimal weight for portability while preserving the option to access the humidification function when required.
Solution Approach 2:
The body unit serves multiple functions: it can operate standalone as a portable CPAP device or connect to the base unit to provide both CPAP and humidification functions. This multi-functionality resolves the contradiction by allowing the same core component to adapt to different usage requirements.

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
Enables high portability by allowing the apparatus to be used without the base unit while maintaining humidification capabilities, reducing bulk and enhancing convenience for travel.
Implementation Method 1
an air-sending device that discharges, via the first outlet, air that is introduced via the first inlet
Implementation Method 2
a humidifier that humidifies air that is introduced via the second inlet
