Solution Overview

Problem

Existing room ventilation systems face challenges in arranging air connections flexibly while minimizing space requirements, as air duct components are often manufacturer-specific and require complex routing, making installation planning difficult.

Innovation Solution

A room ventilation system with a ventilation device and modular air duct components featuring multiple side surfaces and a closure device that allows for adjustable air flow routing, enabling either straight or 90-degree redirection of air flows, and allowing for flexible arrangement and connection of components to accommodate different air connection configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manufacturer-specific air duct components are used for each air connection, then the air flow routing can be precisely controlled, but the device complexity increases and installation planning becomes difficult

Engineering Contradiction:
Improveair flow routing flexibilityVSAvoidnumber of air duct components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a single air duct component that can serve multiple functions and configurations. This component can be arranged in different orientations (0°, 90°, 180°, 270°) and can handle different air connections (outside air, exhaust air, supply air) through a standardized coupling connection design, eliminating the need for manufacturer-specific components for each air connection type.

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

Solution Approach 2:

The patent applies dynamics by making the air duct component rotatable about its longitudinal axis, allowing it to adapt to different installation situations and air flow routing requirements. This rotational capability enables the same component to replace multiple fixed-configuration components, reducing overall system complexity while maintaining routing flexibility.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple manufacturer-specific air duct components are used to guide different air types, then the air connections can be precisely arranged, but the space requirements increase

Engineering Contradiction:
Improveair connection arrangementVSAvoidspace requirement
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

By using a universal air duct component that can be rotated to different orientations, the patent reduces the number of components needed to guide different air types. A single component can replace what would traditionally require multiple manufacturer-specific components, thereby reducing the overall space requirement while maintaining the ability to precisely arrange air connections.

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

Solution Approach 2:

The rotatable design allows the air duct component to adapt to compact installation spaces by orienting itself optimally. This dynamic adjustment capability enables precise air connection arrangement without requiring additional space for multiple fixed components, effectively solving the space constraint problem.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If fixed-configuration air duct components are used, then the manufacturing is simplified, but the installation flexibility is reduced

Engineering Contradiction:
Improveair duct component productionVSAvoidinstallation flexibility
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent introduces a rotatable joint mechanism that allows the air duct component to be manufactured in a standardized configuration while enabling flexible installation through rotation. The standardized coupling connection and rotational capability mean that the same component can be produced once but installed in multiple orientations (0°, 90°, 180°, 270°), thus maintaining manufacturing simplicity while achieving installation flexibility.

Inventive Principle:
Principle #15Dynamics
