Window-Frame Ventilation Adapter Plate With Motorized Flaps
Find Innovative SolutionsGenerate Solutions
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
Engineering Contradiction Analysis
1Ease of manufacture
If centralized ventilation systems are used, then ventilation function is provided, but construction costs increase and energy consumption increases
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
2Loss of energy
If decentralized external wall units are installed, then energy consumption is reduced, but installation complexity increases
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
3Area of stationary object
If external wall units are installed in window frames, then space usage is maximized, but thermal protection is compromised
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
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system reduces construction costs, minimizes energy consumption by shortening air flow paths, and ensures efficient ventilation with minimal space usage, while maintaining thermal and weather protection during unit removal for maintenance.
Implementation Method 1

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.
