Multi-Line Quick Connector Housing for Compact Fluid Line Assembly

Solution Overview

Problem

Existing quick-connect assemblies for fluid lines can only connect one fluid line to a connecting piece, leading to a large number of connections required in vehicles, which complicates assembly and occupies valuable space.

Innovation Solution

A device with a housing featuring two receiving areas, one for receiving multiple fluid-carrying line sections and another for receiving connecting pieces, allowing for the connection of multiple fluid channels to a single connecting piece, thereby reducing the number of connections needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate quick-connect assemblies are used to connect multiple fluid lines, then each fluid line can be connected independently, but the number of connections increases and installation space requirements increase

Engineering Contradiction:

Improvenumber of fluid lines connectedVSAvoidnumber of connections

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate quick-connect assemblies into a single integrated device. The housing contains multiple receiving areas that can simultaneously receive multiple line sections and multiple connecting pieces, allowing multiple fluid lines to be connected through one unified connection assembly rather than requiring separate assemblies for each line.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The device is designed with universal functionality to handle multiple fluid lines simultaneously. The housing structure provides multiple receiving areas that can accommodate different line sections and connecting pieces, enabling a single device to perform the function of multiple separate quick-connect assemblies.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple separate quick-connect assemblies are used to connect multiple fluid lines, then each connection can be made independently, but the installation space required increases

Engineering Contradiction:

Improvenumber of fluid lines connectedVSAvoidinstallation space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines multiple separate quick-connect assemblies into a single integrated device. The housing contains multiple receiving areas that can simultaneously receive multiple line sections and multiple connecting pieces, allowing multiple fluid lines to be connected through one unified connection assembly rather than requiring separate assemblies for each line.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The device structure allows for compact arrangement where multiple line sections and connecting pieces are received within the housing in a nested or compact configuration. The receiving areas are arranged to optimize space utilization, enabling multiple connections to be made within a reduced footprint compared to separate assemblies.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Adaptability or versatility

If multiple separate quick-connect assemblies are used, then each assembly can handle one fluid line, but assembly effort and time increase

Engineering Contradiction:

Improvenumber of fluid lines connectedVSAvoidassembly time

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent combines multiple separate quick-connect assemblies into a single integrated device. The housing contains multiple receiving areas that can simultaneously receive multiple line sections and multiple connecting pieces, allowing multiple fluid lines to be connected through one unified connection assembly rather than requiring separate assemblies for each line.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The device is pre-configured with multiple receiving areas and fluid channels within the housing, allowing multiple connections to be established simultaneously in a single assembly operation. The integrated structure enables all fluid line connections to be made at once rather than requiring sequential assembly of multiple separate components.

Inventive Principle:
