Supercharger Pipe Mounting Integration

Solution Overview

Problem

The existing supercharger designs face challenges in integrating and connecting multiple pipes to the housing efficiently, leading to increased costs and housing size, as well as complex processing work on the mounting surface.

Innovation Solution

The supercharger incorporates a method where pipes are connected by inserting their ends into corresponding holes in the housing and using overlapping flanges to secure them, with a rotation prevention mechanism to prevent detachment, allowing for simplified integration and reduced processing complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple pipes are connected to the housing using separate mounting surfaces, then each pipe can be securely fixed, but the housing size increases and processing complexity increases

Engineering Contradiction:

Improvepipe connectionVSAvoidhousing size

Core Design Contradiction:

Ease of operationVSVolume of stationary object

Solution Approach 1:

The patent combines multiple pipe mounting functions into a single integrated mounting structure. The mounting structure includes a first mounting portion for the first pipe and a second mounting portion for the second pipe, both integrated into one component that attaches to the housing. This merging of mounting functions eliminates the need for separate mounting surfaces on the housing, thereby reducing housing size while maintaining secure pipe connections.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The mounting structure serves multiple functions simultaneously: it provides mounting surfaces for both the first pipe and the second pipe, and acts as a single integrated attachment point to the housing. This multi-functionality allows multiple pipes to be connected without requiring separate dedicated mounting areas on the housing, thus reducing overall housing volume.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If multiple pipes are connected to the housing using separate mounting surfaces, then each pipe can be securely fixed, but processing work on the mounting surface increases

Engineering Contradiction:

Improvepipe connectionVSAvoidprocessing work

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The patent combines multiple pipe mounting functions into a single integrated mounting structure. The mounting structure includes a first mounting portion for the first pipe and a second mounting portion for the second pipe, both integrated into one component that attaches to the housing. This merging of mounting functions eliminates the need for separate mounting surfaces on the housing, thereby reducing housing size while maintaining secure pipe connections.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The mounting structure is segmented into distinct mounting portions (first mounting portion and second mounting portion) that can be independently designed and manufactured. This segmentation allows each portion to be optimized for its specific pipe while the entire mounting structure can be produced as a single integrated component, reducing overall processing complexity.

Inventive Principle:

Principle #1Segmentation

3Volume of moving object

If pipes are integrated and connected at one location, then space around the internal combustion engine is saved, but mounting surface size and processing complexity increase

Engineering Contradiction:

Improvespace utilizationVSAvoidhousing size

Core Design Contradiction:

Volume of moving objectVSVolume of stationary object

Solution Approach 1:

The patent combines multiple pipe mounting functions into a single integrated mounting structure. The mounting structure includes a first mounting portion for the first pipe and a second mounting portion for the second pipe, both integrated into one component that attaches to the housing. This merging of mounting functions eliminates the need for separate mounting surfaces on the housing, thereby reducing housing size while maintaining secure pipe connections.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The mounting structure utilizes three-dimensional spatial arrangement to accommodate multiple pipes. The first mounting portion and second mounting portion are positioned at different locations and orientations on the mounting structure, allowing pipes to be connected in a compact integrated manner without requiring additional housing volume.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A supercharger is provided with: a housing; a rotary shaft that is supported inside the housing to be freely rotatable; a compressor wheel that is provided at one end in an axial direction of the rotary shaft; a cooling water supplying pipe and a cooling water discharging pipe that have a flange part at an end and are connected to the housing; and a lubricant supplying pipe that has a flange part at an end and is connected to the housing. The ends of the cooling water supplying pipe and the cooling water discharging pipe are inserted into a cooling water supplying flow path and a cooling water discharging flow path of the housing, respectively. The end of the lubricant supplying pipe is inserted into a first supplying flow path of the housing. The flange part presses the flange parts in an insertion direction and is fixed to the housing.
