Solution Overview

Problem

Conventional centralized room ventilation systems require extensive ductwork, increasing construction costs and energy consumption, while also limiting the usable space in rooms, and existing decentralized systems lack a simple and space-efficient installation method for external wall units.

Innovation Solution

A decentralized room ventilation system with an external wall unit that includes motor-driven flaps for the outside and exhaust air openings, integrated into a window frame using an adapter plate, allowing for a compact and easy-to-install design that maintains thermal and weather protection during maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If centralized ventilation systems are used, then ventilation function is provided, but construction costs increase and energy consumption increases

Engineering Contradiction:
Improveconstruction costVSAvoidenergy consumption
Core Design Contradiction:
Ease of manufactureVSLoss of energy

Solution Approach 1:

The ventilation system is divided into decentralized external wall units that can be independently installed in window frames, eliminating the need for extensive centralized ductwork and reducing both construction costs and energy losses associated with long air flow paths

Inventive Principle:
Principle #1Segmentation

2Loss of energy

If decentralized external wall units are installed, then energy consumption is reduced, but installation complexity increases

Engineering Contradiction:
Improveenergy consumptionVSAvoidinstallation complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The adapter plate serves multiple functions: it provides a standardized mounting interface for external wall units in window frames, enables easy assembly and disassembly for maintenance, and maintains thermal insulation when flaps are closed, thereby simplifying installation while reducing energy consumption

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

3Area of stationary object

If external wall units are installed in window frames, then space usage is maximized, but thermal protection is compromised

Engineering Contradiction:
Improveusable spaceVSAvoidthermal protection
Core Design Contradiction:

Solution Approach 1:

The adapter plate incorporates motor-driven flaps that can dynamically open or close based on operational requirements, maintaining thermal protection when the external wall unit is not in use while allowing space-efficient installation in the window frame

Inventive Principle:
Principle #15Dynamics

AI summary

The device has a hollow adapter plate arranged in a rigid profile frame (24) of a window front, where the adapter plate exhibits an external air opening and an exhaust air opening. An external wall device (26) is detachable mounted in the adapter plate such that the external wall device communicates with the external air opening and the exhaust air opening. The external air opening and the exhaust air opening are closable by flaps. The flaps exhibit a drive that is driven by an electric motor.
