Oxygen Concentrator Compressor Assembly Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oxygen concentrator and compressor systems lack a compact and unified design for providing breathing gas, leading to cluttered and space-inefficient setups, which can be noisy due to vibration and require complex alignment procedures.
Innovation Solution
An oxygen concentrator and compressor assembly where the compressor housing is positioned on top of the oxygen concentrator housing through a keying or latching mechanism, utilizing congruent surfaces for alignment and a vibration damping structure to reduce noise, allowing for a unified and space-saving system with easy handling and placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If oxygen concentrator and compressor are placed separately, then each device can be optimized independently, but the overall system occupies more space and creates cluttered setup
Solution Approach 1:
The patent combines the oxygen concentrator and compressor into a single integrated assembly where the compressor housing is positioned on top of the oxygen concentrator housing. This merging reduces the overall system footprint and eliminates cluttered setup while maintaining independent optimization of each component through modular design
Solution Approach 2:
The patent employs asymmetric keying mechanisms between the compressor housing and oxygen concentrator housing. The keying feature on one housing engages with a corresponding recess on the other, providing automatic alignment and preventing misplacement. This asymmetric design simplifies the alignment process while enabling compact integration
2Volume of moving object
If compressor is placed near oxygen concentrator, then system becomes more compact, but vibration noise increases
Solution Approach 1:
The patent introduces a vibration damping structure as an intermediary element between the compressor housing and oxygen concentrator housing. This mediator absorbs and dampens vibrations generated by the compressor, preventing them from propagating to the oxygen concentrator and reducing overall system noise while maintaining compact integration
3Manufacturing precision
If housing positions are fixed precisely, then alignment is accurate, but manufacturing and assembly complexity increases
Solution Approach 1:
The patent incorporates pre-formed keying features and recesses during the housing manufacturing process. These preliminary alignment features are integrated into the housing structures themselves, enabling automatic alignment during assembly without requiring complex adjustment procedures or high-precision manual positioning, thus maintaining manufacturing precision while simplifying assembly

AI summary
An oxygen concentrator and compressor assembly. An oxygen concentrator is disposed in a housing having an upper end. A compressor is disposed in a housing having a lower end. The upper end of the oxygen concentrator housing and the lower end of the compressor housing are configured such that placement of the lower end of the compressor housing on the upper end of the oxygen concentrator housing sets the position of the compressor housing with respect to the oxygen concentrator housing.
