Magnetic Louver Blind Structure for Sealed Double-Glazed Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing louver blind structures in double-glazed windows rely on mechanical actuation systems that require mechanical connections, which can compromise the integrity of the window unit and are not aesthetically pleasing.
Innovation Solution
A magnetic actuation system is employed within the louver blind structure, using inner and outer magnets for communication via a frame structure, allowing for pivot movement of louver members between open and closed positions without mechanical connections, thus maintaining the integrity and aesthetics of the window unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical actuation system with gears and mechanical connections is used, then the louver members can be actuated reliably, but the window unit integrity is compromised and aesthetics are degraded
Solution Approach 1:
The patent replaces the traditional mechanical actuation system (gears, strings, pulleys) with a magnetic field-based actuation system. Magnets positioned on the exterior of the window unit create magnetic fields that interact with magnetically responsive materials attached to the louver members, enabling actuation without mechanical connections through the glass or frame, thus maintaining window unit integrity while achieving reliable louver control
Solution Approach 2:
The patent introduces magnetic fields as an intermediary between the exterior control mechanism and the interior louver members. The magnetic field acts as a non-contact mediator that transmits actuation force through the window unit structure without requiring physical mechanical connections, resolving the contradiction between reliable actuation and maintaining structural integrity
2Ease of operation
If a mechanical actuation system with visible components is used, then the louver members can be actuated, but the aesthetics of the window unit are compromised
Solution Approach 1:
By substituting mechanical components with magnetic field interaction, the patent eliminates visible strings, gears, and mechanical connections that would detract from the window's aesthetic appearance. The magnetic actuation system allows for clean, minimalist design while maintaining ease of operation through exterior control
3Ease of operation
If mechanical connections are made through the window structure, then actuation can be achieved, but the sealing and isolation of internal components is compromised
Solution Approach 1:
The magnetic field serves as an intermediary that allows control of interior louver members without creating physical openings or mechanical connections through the window structure. This maintains the sealing integrity and isolation of the internal chamber while enabling reliable exterior control of the louver system
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 magnetic actuation system provides a seamless and visually appealing operation of louver members while ensuring the internal components remain isolated and sealed, eliminating the need for mechanical connections such as pulleys or strings.
Implementation Method 1
an outer magnet interfacing with the inner magnet via the frame structure for magnetic communication therewith

AI summary
A louver-blind double glazed window unit comprises a frame defining first and second faces of the unit with respective first and second windows mounted thereto, and outer side and inner sides. An inner chamber is defined between the frame and the first and second windows. Louvers extend within the chamber and are pivotally mounted to the frame. An actuator assembly is positioned within an operating part of the frame for pivoting the louvers between open and closed positions. An inner magnet is positioned at the inner side of the frame. An external manual operator is movably positioned on the outer side of the frame and comprises an outer magnet magnetically communicating with the inner magnet.Moving the external manual operator along the outer side of the frame causes the inner magnet to move in tandem therewith thereby actuating the actuator assembly to pivot the plurality of louver members.
