Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shading devices for complex window shapes, such as triangular or curved windows, often require visible wires and obstruct the view, compromising the aesthetic appeal and functional design.
Innovation Solution
A shading device with an elongated guide rail arrangement and transversely oriented support members, hidden within a housing, allowing for a wave-like extendable covering that follows the shape of the window, providing stability and an aesthetically appealing solution without visible wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If visible wires are used to support the extendable covering for complex window shapes, then the shading device can accommodate triangular or curved windows, but the view is obstructed and aesthetic appeal is compromised
Solution Approach 1:
The patent extracts the wires from the visible exterior and relocates them inside the housing structure. The support members are received within the housing, with only their necessary functional portions extending to support the covering. This extraction eliminates the harmful visible wires while preserving the adaptability to complex window shapes through the internal wire arrangement.
Solution Approach 2:
The patent implements nesting by placing the support members and wires inside the housing structure. The housing contains the mechanical components, with support members arranged internally to follow the window shape. This nested arrangement hides the wires from external view while maintaining the structural integrity needed for complex geometries.
2Adaptability or versatility
If the extendable covering is pulled up with wires following a curved roof, then the shading device can cover complex window shapes, but the view is obstructed and the feel of the glass roof is changed
Solution Approach 1:
The patent extracts the wire support system from the exterior visible area and relocates it inside the housing. The support members are arranged internally to follow the curved roof shape, eliminating the need for external wires that obstruct the view and alter the aesthetic feel of the glass roof while maintaining the ability to conform to complex geometries.
3Ease of manufacture
If parallel side rails are used for shading devices, then the structure is simple and aesthetically pleasing, but the arrangement is not feasible for tapering windows such as triangular windows
Solution Approach 1:
The patent implements dynamics by making the support members adjustable in position and orientation. The support members can be positioned at different locations along the housing and oriented to match the specific geometry of the window. This dynamic adjustability allows the same simple housing structure to accommodate both parallel-sided windows and tapering triangular windows, maintaining structural simplicity while achieving geometric adaptability.
Solution Approach 2:
The patent applies local quality by allowing different portions of the housing to have different configurations. The support members can be positioned and oriented differently in different sections of the housing to match the local geometry requirements. This enables the same overall simple housing structure to adapt to varying window shapes through localized adjustments.

AI summary
A shading device for being arranged in association to a window includes an elongated guide rail arrangement that is adapted to be stationarily arranged relative to the window, an extendable covering, at least one elongated support member and a movement arrangement. The extendable covering is supported by the at least one elongated support member, wherein the at least one elongated support member is arranged to extend with its longitudinal direction in a transverse orientation relative to a longitudinal direction of the elongated guide rail arrangement and arranged to be movable along the elongated guide rail arrangement in the transverse orientation by the movement arrangement so that the extendable covering may be moved between a retracted state and an extended state for covering the window to different extents.
