Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter assemblies for oxygen concentrators and ventilators are not universally adaptable to different compressor assemblies, leading to inefficiencies in air filtration and noise attenuation, requiring multiple filter types for various air flow requirements and resulting in increased maintenance and noise issues.
Innovation Solution
A universal filter assembly with a compartmented housing structure and adjustable air flow control, featuring a rotatable dial to regulate air flow and noise attenuation through baffle and noise attenuating members, allowing compatibility with multiple compressor assemblies and reducing noise levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a filter assembly is specifically designed for a particular oxygen concentrator or breathing apparatus, then it provides the minimum required air flow for proper operation, but it cannot be used with other models having different air flow requirements
Solution Approach 1:
The filter assembly is designed with an adjustable inlet opening that can be modified to match the air flow requirements of different compressor assemblies. This universal design allows a single filter assembly to serve multiple models of oxygen concentrators and breathing apparatus, eliminating the need for model-specific filters while maintaining proper air flow characteristics for each application.
Solution Approach 2:
The inlet opening of the filter assembly is made adjustable rather than fixed, allowing the opening size to be dynamically changed to match different air flow requirements. This dynamic adjustment capability enables the same filter assembly to adapt to various compressor assemblies with different air flow needs, resolving the contradiction between providing sufficient air flow and maintaining versatility.
2Productivity
If a large compressor is used to provide higher rates of oxygen, then oxygen flow rate capacity increases, but noise generation becomes excessive
Solution Approach 1:
A baffle member is introduced as an intermediary element between the compressor and the external environment. This baffle structure absorbs and redirects sound waves, reducing noise transmission while allowing the compressor to operate at higher capacities. The baffle acts as a mediator that maintains the beneficial high oxygen flow rate capacity while eliminating the harmful excessive noise generation.
