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

VSEngineering 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

Engineering Contradiction:
Improveadjustability to different anglesVSAvoidindependent hinge mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice 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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improvesupport stabilityVSAvoidadjustability with window opening
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #35Parameter changes

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

Engineering Contradiction:
Improveconstruction simplicityVSAvoidfitting to tight spaces
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
ImproveadjustabilityVSAvoidmanual effort required
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

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.

Inventive Principle:
Principle #25Self-service

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.
