Extendable window prop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window props are not adequately designed to support double-hung windows, particularly in terms of adjustability and stability, which can lead to inefficient use and potential damage to the windows.
Innovation Solution
An adjustable pole with a crossbar and perpendicularly extending rods that can be positioned to support and abut the window frames, along with spacers and a foot for stability, allowing for secure and adjustable support of double-hung windows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing window props are used, then the structure is simple, but the support stability and adjustability are insufficient
Solution Approach 1:
The window prop is divided into multiple functional segments: an adjustable pole with telescopic sections, a crossbar with positioning mechanisms, and rods that can be independently positioned. This segmentation allows each component to perform its specific function optimally while providing overall stability and adjustability.
Solution Approach 2:
The pole features adjustable length through telescopic sections that can be extended or retracted, and the rods can be positioned at different locations along the pole. This dynamic adjustability allows the prop to adapt to various window sizes and support requirements, enhancing reliability without requiring a completely complex structure.
2Adaptability or versatility
If existing window props are used, then the device is simple to manufacture, but the adaptability to different window configurations is poor
Solution Approach 1:
The crossbar is designed to accommodate multiple rod positions and can support windows of different sizes and types. The adjustable pole length and positioning mechanisms allow the same device to adapt to various window configurations, providing universal applicability while maintaining reasonable manufacturing simplicity through standardized components.
Solution Approach 2:
The adjustable pole with telescopic sections and positionable rods provides dynamic adaptability to different window configurations. This adjustability is achieved through straightforward mechanical mechanisms that remain relatively simple to manufacture while significantly enhancing versatility.
3Manufacturing precision
If existing window props are used, then the structure is straightforward, but the precision of window positioning is insufficient
Solution Approach 1:
The crossbar includes pre-positioned rods at specific locations along the pole, and the adjustable pole sections are designed with predetermined positioning points. This preliminary arrangement of positioning features enables precise window placement without requiring complex adjustment mechanisms during installation.
Solution Approach 2:
The positioning system is segmented into discrete adjustable sections on the pole and individually positionable rods. This segmentation allows for precise positioning through simple mechanical adjustments rather than complex continuous control mechanisms, achieving high positioning precision with moderate complexity.

AI summary
An extendable window prop for supporting double-hung windows includes a pole that is of adjustable length. A crossbar is coupled to and extends perpendicularly from an upper end of the pole. A first rod is coupled proximate to the upper end of the pole and extends substantially perpendicularly from the pole. The first rod is substantially perpendicular to the crossbar. A second rod is coupled to and extends substantially perpendicularly from the first rod distal from the pole. The second rod is transverse to the pole. The crossbar is positioned on the pole such that the crossbar is configured to position a first window. The first window is supported by the pole. The second rod is positioned on the first rod such that the second rod is positioned to abut a frame of the first window that is positioned on the crossbar.
