Solution Overview

Problem

Existing adapters for connecting air ducts to ventilation devices require complex and time-consuming assembly processes, often necessitating significant installation space and multiple steps due to the need for individual adapters and air lines to maintain distance for assembly, which can be impractical in limited spaces.

Innovation Solution

A compact, one-piece adapter with multiple fluidically separated channels, allowing preassembly of air lines and simplified installation by eliminating the need for assembly clearances between individual ducts, featuring adaptable channel orientations and connections that can accommodate various geometries and sizes, made from high thermal resistance plastics like polypropylene for efficient energy transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple individual adapters are used to connect air ducts to a ventilation device, then each adapter can be connected to air ducts of different sizes and cross-sections, but the assembly process becomes complex and time-consuming, and significant installation space is required to maintain distance between individual adapters and air lines for assembly

Engineering Contradiction:
Improveadaptability to different air duct sizesVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple individual adapters into a single integrated adapter body with multiple channels. The adapter body (1) contains multiple fluidically separated channels (6, 7, 8, 9) that can simultaneously connect different air ducts to the ventilation device, eliminating the need for multiple separate adapters and reducing assembly complexity while maintaining adaptability to various duct configurations

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The adapter body is designed as a universal component that can accommodate multiple types of air duct connections simultaneously. Each channel can be configured for different duct sizes and geometries, allowing a single adapter to perform the function of multiple specialized adapters, thereby reducing both assembly complexity and installation space requirements

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If multiple individual adapters are used to connect air ducts to a ventilation device, then each adapter can be independently connected, but the installation space requirements increase due to the need for assembly clearances between individual ducts

Engineering Contradiction:
Improveease of assemblyVSAvoidinstallation space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

By merging multiple adapter functions into a single integrated body, the patent eliminates the need for assembly clearances between individual adapters. The compact design allows air lines to be pre-assembled on the adapter body and then installed as a single unit, significantly reducing the installation space required while maintaining ease of operation through simplified assembly procedures

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The adapter design enables pre-assembly of air lines on the adapter body before final installation. The channels and connections are pre-configured in the adapter body, allowing air lines to be attached in advance and the entire assembly to be installed in one operation, reducing both installation space requirements and on-site assembly complexity

Inventive Principle:
Principle #10Preliminary action

3Area of stationary object

If a compact adapter design is used to reduce installation space, then the adapter can be installed in limited spaces, but the assembly process may become more difficult due to restricted access

Engineering Contradiction:
Improveinstallation spaceVSAvoidease of assembly
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The adapter body is segmented into multiple independent channels that are fluidically separated. This segmentation allows each channel to be independently configured and connected to different air ducts, enabling flexible assembly in compact spaces while maintaining ease of operation through modular connection points and standardized interfaces

Inventive Principle:
Principle #1Segmentation

AI summary

The adapter (1) has multiple fluidic channels (6,7), which are separated from each other. Each channel has two connections (3,4), where each former connection is formed for connection to a ventilation device or an air distribution device and each latter connection is formed for arrangement of an air line. The adapter is made of plastic with high thermal resistivity such as polypropylene.
