Pivoting Window Sill With Integrated Sliding Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pivoting window sills are cumbersome to operate and require additional manual effort, with limited variability and space constraints, especially when used as interior window sills.
Innovation Solution
A horizontally displaceable window sill integrated with the window's movement, utilizing a hinge-free design that allows for adjustment up to 90 degrees, with optional support heads and guides for stability, and the option of electrical control via a servomotor for enhanced operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional pivoting window sill with independent hinge is used, then the window sill can be adjusted to different angles, but it requires additional storage space for the hinge and increases device complexity
Solution Approach 1:
The patent merges the hinge function with the window frame structure itself. The horizontal leg of the window frame serves as the pivot support, eliminating the need for a separate hinge mechanism. This integration maintains the adaptability to adjust to different opening angles while significantly reducing device complexity and eliminating additional storage requirements for independent hinge components.
Solution Approach 2:
The window frame's horizontal leg is designed to serve multiple functions: it acts as both the structural support for the window and the pivot axis for the window sill. This multi-functionality eliminates the need for dedicated hinge components, reducing overall device complexity while maintaining full adjustability.
2Stability of the object's composition
If a rigid window sill is used, then it provides stable support for objects, but it cannot be adjusted when the window is opened
Solution Approach 1:
The patent transforms the rigid, fixed window sill into a dynamic, adjustable component. The window sill can pivot relative to the window frame, allowing it to adapt its position based on the window's opening angle. This dynamic capability maintains support stability when needed while providing adjustability during window operation.
Solution Approach 2:
The window sill's position parameters (angle and horizontal position) can be changed according to the window's opening state. The longitudinal sliding guide allows horizontal displacement, while the pivot connection enables angular adjustment, allowing the window sill to maintain optimal positioning across different window configurations.
3Ease of manufacture
If the window sill is fixed in position, then it is simple to construct, but it requires sufficient free space and cannot be fitted to reveals with slight clearance
Solution Approach 1:
The window sill incorporates dynamic positioning capabilities through the longitudinal sliding guide and pivot connection. This allows the window sill to be fitted to reveals with slight clearance by adjusting its horizontal position and angle, while the construction remains relatively simple by utilizing the window frame's existing structure as the pivot axis.
4Adaptability or versatility
If a pivoting window sill with manual operation is used, then it can be adjusted, but it requires additional manual effort and is time-consuming
Solution Approach 1:
The window sill adjustment system is designed to work with the window's natural movement. As the window is opened or closed, the window sill automatically pivots and adjusts its position through the longitudinal sliding guide, eliminating the need for separate manual adjustment operations. The system serves itself by utilizing the window's motion to drive the window sill's positioning.

AI summary
The sill (10) is horizontally oriented and pivotably mounted, where the sill is controlled by pivoting movement of a pivotable window (14) arranged above the sill. Horizontal relocatability takes place by a sliding longitudinal guide between the window and the sill. A transverse guide is provided for variable positioning of the sill in a transverse direction. The pivoting movement of the window takes place by a servomotor. The sill is made up of wood, plastic, metal or stoneware. The servomotor receives a position signal by a sensor arranged at the window.
