Solution Overview

Problem

Radial compressors face issues with fragility due to external pipes breaking under engine vibrations, leading to potential oil leakages and difficulties in handling and mounting, especially in shipping and usage.

Innovation Solution

Integrating the distribution system into the housing of the radial compressor, where the housing parts are connected adjacent to each other in the longitudinal direction of the shaft, forming a robust and compact design that reduces vibration risks and simplifies handling and mounting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If external pipes are used to supply service fluid to bearings and sealing, then the radial compressor can be assembled with separate components, but the external pipes are fragile and may break due to engine vibrations during usage

Engineering Contradiction:
Improveassembly flexibilityVSAvoidrobustness against vibrations
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The distribution system is integrated into the housing as an integral part, merging the previously separate external pipes and housing into a single robust structure. This eliminates the fragility of external pipes while maintaining the functionality of service fluid supply to bearings and sealing, directly resolving the contradiction between assembly flexibility and vibration resistance

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple external pipes are used for service fluid supply, then the radial compressor can have separate supply elements, but the compressor becomes more difficult to handle and mount during shipping and installation

Engineering Contradiction:
Improvesupply configuration flexibilityVSAvoidhandling and mounting ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The distribution system with multiple feed branches is merged into the housing structure, creating a single integrated component that maintains the versatility of multiple service fluid supply paths while eliminating the handling difficulties associated with multiple separate external pipes. The integral design allows the entire assembly to be treated as one unit during shipping and installation

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If the distribution system is integrated into the housing, then the radial compressor becomes more robust and compact, but the manufacturing complexity of the housing increases

Engineering Contradiction:
Improverobustness and compactnessVSAvoidhousing manufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The housing is divided into multiple housing parts that are connected to each other, with the distribution system extending through at least two of these parts. This segmentation allows the complex integrated distribution system to be manufactured in manageable sections and then assembled, reducing the manufacturing complexity while maintaining the robustness and compactness benefits of integration

Inventive Principle:
Principle #1Segmentation

AI summary

Radial compressor and exhaust gas recirculation system The invention relates to a radial compressor (2) comprising an impeller (4), a motor (8) for driving the impeller (4), which motor (8) exhibits a shaft (40), a housing (10) for the motor (8) and a distribution system (18) for a service fluid for the motor (8), wherein the distribution system (18) comprises a main feed (28), a manifold (36) and at least two feed branches (37, 38), wherein the service fluid can be conducted through the main feed (28), the manifold (36) and the at least two feed branches (37, 38), and wherein the main feed (28) and the feed branches (37, 38) join in the manifold (36). A radial compressor with an enhanced design may be achieved in that the distribution system (18) is an integral part of the housing (10) and in that the housing (10) comprises several housing parts (12, 14, 16), which are connected to each other and which are arranged adjacent to each other in longitudinal direction of the shaft (40), wherein the distribution system (18) extends through at least two of the housing parts (14, 16).
