Adjustable False Upright for Motorized Sliding Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for motorizing classic, non-motorized windows are inefficient due to the need for on-site adjustments, which can be time-consuming and irreversible, especially when the sliding frame is not at a standard distance from the ground.
Innovation Solution
A motorization device with a tubular casing and adjustable end pieces that can be telescoped or have movable elements to adjust the length of a false upright, allowing the electric motor and pinion to be securely positioned relative to the window frame, enabling flexible installation without requiring on-site cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the tubular casing is cut on site to adjust the length of the false upright, then the device can be adapted to different window configurations, but the installation time increases and the adjustment is irreversible
Solution Approach 1:
The false upright is divided into modular segments that can be assembled in different combinations to achieve the required length. The tubular casing consists of multiple interchangeable segments with standardized connection interfaces, allowing installers to configure the appropriate length without cutting or irreversible modification.
Solution Approach 2:
The false upright length is made dynamically adjustable through interchangeable segments rather than fixed. The system allows for length modification by replacing segments rather than cutting, enabling adaptation to various window heights while maintaining the integrity of the components.
2Adaptability or versatility
If the tubular casing is cut on site to adjust the length, then the device can fit different window configurations, but the adjustment cannot be reversed and causes time loss
Solution Approach 1:
The false upright is divided into modular segments that can be assembled in different combinations to achieve the required length. The tubular casing consists of multiple interchangeable segments with standardized connection interfaces, allowing installers to configure the appropriate length without cutting or irreversible modification.
Solution Approach 2:
The modular segments are designed to be reusable and interchangeable. If an installation error occurs or adjustment is needed later, segments can be removed and replaced without waste, as none of the components are discarded or permanently modified during the adjustment process.
3Device complexity
If fixed-length false uprights are used, then the device structure is simple, but it cannot accommodate different window configurations
Solution Approach 1:
The false upright is divided into modular segments that can be assembled in different combinations to achieve the required length. The tubular casing consists of multiple interchangeable segments with standardized connection interfaces, allowing installers to configure the appropriate length without cutting or irreversible modification.
Solution Approach 2:
The modular segments are designed with universal connection interfaces that work across all segment types. A single set of standardized connectors can join any combination of segments, allowing the same component design to serve multiple length requirements and different window configurations.

AI summary
The device (1) has an electric motor (6) driving an operating pinion that is engaged with a rack (5) for displacing a frame (4) in a door frame (3). A dummy post (8) is constituted by a tubular casing (9), and the electric motor is installed at an interior of the tubular casing. The dummy post has an adjusting unit (30) adjusting a position of fixation units of an endpiece (12) with respect to an end (10) of the casing associated to the endpiece so as to permit adjustment of length of the dummy post.
