Universal Holder for Roof Window Sun Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sun protection devices for roof windows face issues with high storage costs and incorrect assembly due to the need for multiple holder sets for different frame geometries, and current solutions result in a flexible attachment that can lead to damage during operation or installation.
Innovation Solution
A holding device with a holding element that can be oriented in multiple positions relative to the contact surface, allowing the same holder to be used for various frame geometries, featuring a pivot bearing design for stability and flexibility, and including fastening means for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a convex contact surface with different bores for different angles is provided, then the holder can be adapted to different frame geometries, but only a relatively small portion of the contact surface rests against the side wall resulting in flexible mounting that cannot prevent pivoting
Solution Approach 1:
The holding element is made movable relative to the mounting surface through a pivot bearing, allowing the holder to dynamically adapt to different frame geometries while maintaining stable contact. The pivot bearing enables the holding element to pivot about a pivot axis perpendicular to the pivot plane, providing both adaptability and reliability.
Solution Approach 2:
The solution moves from a fixed 2D contact surface problem to a 3D spatial solution by introducing a pivot bearing that allows rotation in three-dimensional space. This enables the holding element to achieve stable contact in multiple orientations and angles.
2Reliability
If multiple holder sets are provided for different frame geometries, then each geometry can be properly accommodated, but storage costs and device complexity increase
Solution Approach 1:
The holder is designed with universal functionality through the pivot bearing mechanism, allowing a single holder design to serve multiple frame geometries. The holding element can pivot to accommodate different angles and orientations, making the holder multi-functional and eliminating the need for multiple specialized holder sets.
Solution Approach 2:
The holder accommodates different frame geometries by changing its orientation parameter through pivoting. Instead of having different holders for different geometries, the same holder changes its angular parameter via the pivot bearing to adapt to various frame configurations.
3Ease of manufacture
If a flat contact surface is used, then manufacturing is simple, but the holder can pivot during operation or installation causing damage
Solution Approach 1:
Rather than using a complex non-flat contact surface, the invention uses a simple flat contact surface combined with a dynamic pivot bearing mechanism. The pivot bearing controls the pivoting motion, allowing the holder to adapt to different geometries while preventing uncontrolled pivoting that would cause damage.

AI summary
In a holding device for holding a sun protection device (10) with a holder (14) for mounting on a side wall (13) bounding a light entry opening (11), wherein the holder (14) has a contact surface for bearing against the side wall (13) and a holding element (22) on which the sun protection device (10) can be arranged under a first orientation to the contact surface (34), a reliable and stable positioning can be achieved independently of the frame geometry of a window frame by the fact that the holding element (22) is spaced away from the contact surface (34), and that the sun protection device (10) can be arranged on the holding element (22) under at least a second orientation to the contact surface (34).
