Vehicle Door Window Assembly With Edge-Mounted Drive Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The surface area of vehicle windows is often limited by the mechanism that drives the mobile window between open and closed positions, restricting available space for additional windows and obstructing visibility.
Innovation Solution
A window assembly with a first drive and transmission mechanism that allows the mobile window to slide parallel to a stator, enabling it to occupy space past the drive in the closed position, allowing for additional windows without obstruction, and featuring a compact, electrically powered rotor and stator arrangement for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the drive mechanism is arranged inside the door at the bottom part under the mobile window, then the window mechanism can be compactly integrated, but the available space for arranging windows is limited and visibility is reduced
Solution Approach 1:
The patent repositions the drive mechanism from a horizontal arrangement inside the door to a vertical arrangement along the edge of the door. This dimensional change allows the drive to occupy the vertical space along the door edge rather than consuming horizontal window area, thereby resolving the contradiction between compact integration and available window space.
2Ease of operation
If the mobile window is positioned to maximize visibility when open, then ventilation and visibility are improved, but the window mechanism requires more space that could be used for additional windows
Solution Approach 1:
By moving the drive mechanism to the vertical edge of the door, the patent creates horizontal space that can be utilized for additional fixed windows. This dimensional reorganization allows the mobile window to maintain its full travel range for ventilation while the newly available horizontal space accommodates fixed windows for enhanced visibility.
3Illumination intensity
If fixed windows are added to improve visibility, then driver and passenger visibility is enhanced, but the drive mechanism obstructs the view through these windows
Solution Approach 1:
The patent extracts the drive mechanism from the interior space of the door where it would obstruct the view through fixed windows, and relocates it to the vertical edge of the door. This separation removes the harmful obstruction effect while preserving the beneficial visibility enhancement from having fixed windows.
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
This configuration increases available window surface area, enhancing driver and passenger visibility, especially in heavy-duty vehicles, by allowing more space for additional windows and improving safety during vehicle maneuvering.
Implementation Method 1
a first drive, comprising a first stator and a first rotor, the first rotor being arranged around the first stator for rotating relative to the first stator, about a first longitudinal axis fixed relative to the first stator, when the first drive is electrically powered
Implementation Method 2
a first transmission mechanism, the mobile window being driven between the open position and the closed position by the rotation of the first rotor, via the first transmission mechanism
