Respiratory Containment Chamber for Noise Reduction Without Soundproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing respiratory devices, such as CPAP and BiPAP machines, face noise issues due to soundproofing materials degrading over time, releasing harmful particles and posing health risks, while also being costly and environmentally harmful.
Innovation Solution
A respiratory device with a containment chamber that reduces noise by converting sound energy into kinetic energy through vibration, using materials like silicone and plastic, eliminating the need for soundproofing materials, thus enhancing safety and reducing environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If soundproofing materials are used in the gas passage, then noise is reduced, but the materials degrade over time releasing harmful particles
Solution Approach 1:
The patent removes soundproofing materials from the gas passage entirely, extracting the harmful element while maintaining noise reduction through alternative means (device structure and blower positioning)
Solution Approach 2:
The patent introduces a containment chamber as an intermediary structure that isolates the blower and contains noise without requiring soundproofing materials that release particles
2Object-affected harmful factors
If soundproofing materials are used in the gas passage, then noise is reduced, but the device complexity and cost increase
Solution Approach 1:
The patent merges the noise reduction function into the overall device structure by positioning the blower within the containment chamber and using the housing structure itself for noise containment, eliminating the need for separate soundproofing materials
Solution Approach 2:
The containment chamber serves multiple functions: it houses the blower, contains noise, and structures the gas passage, replacing the need for dedicated soundproofing components
3Object-affected harmful factors
If soundproofing materials are used in the gas passage, then noise is reduced, but the materials degrade and require replacement
Solution Approach 1:
The patent removes degradable soundproofing materials from the system, eliminating the lifespan limitation they impose on the device
Solution Approach 2:
The patent changes the approach to noise reduction from using degradable materials to using a structural solution (containment chamber) that maintains its noise reduction properties throughout the device's operational life

AI summary
A respiratory device with a containment chamber, configured to deliver pressurized breathable gas to a patient's airway, including a blower configured to generate pressurized breathable gas, a gas passage with at least two chambers, and a casing that houses the gas passage. At least one of the at least two chambers is a containment chamber, the other chambers are at least one flow chamber. The containment chamber communicates with the at least one flow chamber through a neck. When the respiratory device is in use, the airflow substantially does not pass through the containment chamber; the neck is only configured to communicate with the chambers and allows minimal or no airflow through it. Noise enters the containment chamber through the neck and dissipates by resonating with the walls of the chambers, achieving maximal noise reduction for the respiratory device.
