Double-Opening Window Vertical-to-Horizontal Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional windows, such as side-hinged and bottom-hung casements, protrude into the room when open and limit airflow, while bottom-hung casements restrict direct interaction with the outside environment.
Innovation Solution
A side hung and bottom hung double-opening window system featuring a handle, top-link and down hinges, angle-turning devices, a latch block, sliding piece, and latch piece that allow for full window surface opening and intermediate openings of any size, enabling both side hung and bottom hung operations by converting vertical movements into horizontal movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If side-hinged windows are used to enable full window opening, then the opening area is improved, but the window protrudes deeply into the room space
Solution Approach 1:
The patent applies dimensionality change by transitioning from traditional side-hinged rotation (horizontal arc) to a combined vertical-horizonal movement system. The window sash moves vertically downward first, then horizontally outward, effectively changing the opening trajectory from a single-plane rotation to a two-dimensional compound motion. This allows the window to open fully while maintaining a compact profile that does not protrude deeply into the room.
2Volume of moving object
If bottom-hung casements are used to maintain compact size, then the protrusion into room is reduced, but the airflow and direct opening capability are limited
Solution Approach 1:
The patent implements dynamics by providing a multi-mode opening system that can adapt between different opening configurations. The window can operate in bottom-hung mode for compact positioning, side-hung mode for maximum airflow, or intermediate positions. The dynamic control system allows the window to transition between these modes based on operational requirements, optimizing both compactness and airflow capability.
Solution Approach 2:
The patent applies universality by designing a single window system that performs multiple functions: it can open in bottom-hung configuration for compact storage, switch to side-hung configuration for maximum airflow and direct outdoor access, and accommodate intermediate opening positions. This multi-functional capability allows the window to satisfy both the compact size requirement and the high airflow requirement under different operational conditions.
3Adaptability or versatility
If traditional single-opening mechanisms are used, then the device complexity is low, but the versatility of opening options is limited
Solution Approach 1:
The patent applies merging by integrating multiple hinge systems (top-link hinge and down hinge), angle-turning devices, and latch mechanisms into a unified control system. These components work together as a coordinated assembly, where the handle operation simultaneously controls the angle-turning devices, which in turn coordinate the movement of both hinges and latch blocks. This merged system provides versatile opening options while managing complexity through integrated design.

AI summary
A side hung and bottom hung double-opening window includes a first casement, a handle, a first top-link hinge and a first down hinge, a first angle-turning device, a second casement, a second top-link hinge and a second down hinge, a second angle-turning device, a latch block, a sliding piece, and a latch piece. The window can realize side hung and bottom hung double-opening, thus providing the user with other options to open it. Furthermore, the window has a smaller size and a higher reliability.
