Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressors used in ventilators and anesthesia devices face challenges in achieving a compact configuration, optimal performance characteristics, and low sound emissions simultaneously, which is essential for minimizing noise burden on patients and nursing staff.
Innovation Solution
The proposed compressor design features a rotatably mounted compressor impeller enclosed by a spirally configured collection housing and a cover element, with uncoupling elements between these components and a functional component connected to the electric motor, to prevent vibration transmission and achieve effective sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a secondary housing is added to enclose the compressor and spiral housing to minimize sound emissions, then sound emissions are reduced, but the device complexity and size increase
Solution Approach 1:
The patent combines the secondary housing and spiral housing into a single integrated housing structure. The housing includes a spiral section that forms both the collection housing for the compressed gas and the enclosing structure, eliminating the need for separate secondary housing while maintaining sound emission reduction benefits.
Solution Approach 2:
The housing is designed to perform multiple functions simultaneously: it encloses the compressor to reduce sound emissions, guides the gas flow through its spiral configuration, and provides structural support. This multi-functional design eliminates the need for additional components.
2Object-affected harmful factors
If uncoupling elements are added between the motor assembly and housing to reduce vibration transmission, then sound emissions are reduced, but the device complexity increases
Solution Approach 1:
The patent introduces an uncoupling element as an intermediary component between the motor assembly and the housing. This element acts as a vibration damper that reduces the transmission of vibrations from the motor to the housing, thereby reducing sound emissions without requiring complex mounting structures.
3Productivity
If the compressor impeller is enclosed by a collection housing and cover element with gaps for sealing, then pneumatic performance is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs a cover element that can be positioned at a defined distance from the impeller, creating a gap that is sealed through the housing design. The housing includes a collection section and cover element that work together to contain the compressed gas while allowing for practical manufacturing tolerances.
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 a compact compressor configuration with improved pneumatic performance, reduced sound emissions, and minimized flow losses, while maintaining a simple structural configuration and low manufacturing costs.
Implementation Method 1
At least one uncoupling element is arranged between the cover element and the collection housing for vibration damping
Implementation Method 2
a rotatably mounted compressor impeller connected to an electric motor via a drive shaft is arranged. During a rotation of the compressor impeller, the air and/or gas stream is delivered

AI summary
A compressor (1), or ventilator/anesthesia device with the compressor, includes a housing, a rotatable impeller (6) connected via a drive shaft (4) to an electric motor (5) to deliver gas from an inlet (8), upstream on a suction side (7) through a flow duct (11) to a downstream outlet (10) on a delivery side (9). The compressor impeller is partially enclosed by the housing, as a collection housing (2) on the delivery side, and a cover element (12), on the suction side separated in sections from the compressor impeller by a gap (13). An uncoupling element (15) is arranged, for vibration damping and for at least partial sealing of the housing interior against a surrounding area (16), between the cover element and the collection housing and between a functional component (14) connected at least indirectly to the compressor impeller and/or to the electric motor and the collection housing.
