Window Holder Spacer for Surface Element Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holders for sun protection or blackout devices are limited in their ability to reliably fix the surface element in applications beyond motor vehicle windows, failing to accommodate different window profiles and impairing the functionality of folding sashes.
Innovation Solution
A holder design featuring a spacer element that extends away from the receiving element, allowing the surface element to be positioned within the window frame profile, with a compact and stable configuration that maintains the integrity of the folding sash and allows for water drainage, using a one-piece construction made of plastic with angled sections for secure clamping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the holder is designed to hold the surface element in a motor vehicle window, then the holder can be inserted between the seal and trim part, but the holder cannot be used for other applications such as building windows with different profiles
Solution Approach 1:
The holder is designed with a receiving element and spacer element configuration that can accommodate multiple window types (motor vehicle windows, building windows with folding sashes, and windows in masonry). The receiving element can be inserted through receiving openings in various window profiles, and the spacer element adapts to different boundary surfaces, making the same holder design universally applicable across different applications without requiring application-specific modifications.
2Reliability
If the spacer element extends laterally away from the receiving element to position the surface element in the window frame profile, then the surface element can be securely positioned, but the spacer element may load the covering material
Solution Approach 1:
The spacer element is designed to extend laterally away from the receiving element in the cross-section, extracting the positioning function from the receiving element. This allows the spacer element to contact the window frame profile boundary surfaces directly, while the receiving element maintains contact only with the frame of the surface element, preventing the covering material from being loaded by the spacer element.
Solution Approach 2:
The spacer element extends in a direction perpendicular to the receiving direction, creating a three-dimensional configuration where the receiving element and spacer element operate in different spatial dimensions. This dimensional separation allows the spacer element to provide lateral positioning without transmitting forces to the covering material through the receiving element.
3Reliability
If the holder is installed in the window frame profile with the folding sash closed, then the surface element can be fixed, but the folding sash functionality may be impaired
Solution Approach 1:
The holder acts as an intermediary device installed in the window frame profile that provides a stable mounting structure for the surface element without interfering with the folding sash mechanism. The receiving element and spacer element are positioned to contact only the frame profile and surface element frame, respectively, leaving the folding sash free to operate without obstruction or impairment.

AI summary
The invention relates to a holder for a surface element of a sun protection or blackout device, which is provided for covering a window pane with a covering made of a thin covering material and a frame surrounding the edge, preferably designed as a tension frame, wherein the holder has a receiving element for forming a receiving space bounded by a receiving opening, into which a section of the frame, preferably covered with the covering material, is to be inserted through the receiving opening in a receiving direction and against a receiving stop of the receiving element opposite the receiving opening, wherein the receiving element is arranged in a space between planes bounded by two planes parallel to the receiving direction and perpendicular to a cross-sectional plane,wherein a spacer element extending away from the receiving element comprises at least one spacer element end facing away from the receiving element, which is arranged outside the plane gap for positioning the surface element in a window frame profile. The invention further relates to a surface element for covering a window pane and to a sun protection or blackout device comprising a surface element for covering a window pane.
