Window Sash Actuation via Electromagnetic Series
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional windows with pivoting sashes can be inconvenient or difficult to operate, especially when installed high on walls, as they require manual effort for opening and closing, which can be a challenge for accessibility and convenience.
Innovation Solution
An apparatus and method utilizing a series of magnet sets, including electromagnets and permanent magnets arranged in an accordion configuration between the window sash and frame, allowing for automatic operation by controlling the magnetic fields to pivot the sash open or closed through the generation of electrical currents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation of window sash is used, then device complexity is reduced, but ease of operation deteriorates when window is installed high on wall
Solution Approach 1:
The patent replaces manual mechanical operation with an electromagnetic system. Electromagnets are positioned between the sash and frame to provide automatic opening and closing forces, eliminating the need for manual pushing or pulling of the window sash.
Solution Approach 2:
The patent introduces magnet sets as intermediary components between the control system and the window sash. These magnet sets include electromagnets and permanent magnets that mediate the force transmission to move the sash automatically.
2Extent of automation
If magnet sets are positioned between sash and frame, then automation is achieved, but device complexity increases
Solution Approach 1:
The patent divides the magnetic system into multiple discrete magnet sets positioned at different locations between the sash and frame. Each magnet set can be independently controlled, allowing segmented automation of different portions of the window opening/closing operation.
Solution Approach 2:
The patent employs both electromagnets and permanent magnets that can dynamically adjust their magnetic field strength and polarity. This dynamic control allows the system to achieve automation while managing complexity through adaptive force application rather than fixed mechanical linkages.
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
Enables convenient and automated operation of windows, ensuring easy opening and closing without manual effort, enhancing accessibility and usability, particularly for hard-to-reach installations.
Implementation Method 1
conducting an electrical current though the first magnet, the electrical current generating a magnetic field
Implementation Method 2
moving the second magnet relative to the first magnet in response to the magnetic field generated by the first magnet

AI summary
An apparatus and method for moving a window sash relative to a window frame. A window comprises a frame and a sash pivotally connected to the frame. A plurality of members are positioned between the sash and the frame, and the plurality of members are arranged in a series. A plurality of magnet sets comprise at least a first magnet operably connected to one member in the series of members and at least a second magnet operably connected to another member in the series of members. The first magnet is adjacent the second magnet, and at least one of the first or second magnets is an electromagnet. Energizing the electromagnets causes the members in the series of members to move relative to each other and causes the sash to move relative to the frame.
