Building Opening Protection Frame With Integrated Retaining Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective devices for building openings, such as windows, face challenges in securely attaching retaining elements to the frame without play or additional components, which affects the seal's effectiveness.
Innovation Solution
The retaining element is directly attached to the profile strip of the frame using a receptacle designed as a channel within the profile strip, ensuring a secure fit through friction and form-fitting, eliminating the need for additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If additional components are used to attach the retaining element to the profile strip, then the attachment is possible, but play occurs between the retaining element and the frame
Solution Approach 1:
The retaining element is integrated directly into the profile strip structure, merging two previously separate components (retaining element and profile strip) into a unified construction. This eliminates the need for additional attachment components and prevents play between the retaining element and frame by creating a monolithic structure where the retaining element forms an integral part of the profile strip.
Solution Approach 2:
The retaining element is nested within the profile strip, with the retaining element positioned inside or within the structural boundaries of the profile strip. This nesting arrangement ensures precise fit and eliminates play by incorporating the retaining element within the existing profile strip geometry rather than attaching it as a separate external component.
2Ease of operation
If the retaining element is attached to the corner connector, then attachment is simplified, but the overlap between the protective device and frame is reduced
Solution Approach 1:
The profile strip is segmented to include a dedicated receptacle portion that specifically receives the retaining element. This segmentation allows the retaining element to be positioned optimally within the profile strip structure, maximizing the overlap between the protective device and frame while maintaining ease of installation through the specialized receptacle design.
Solution Approach 2:
The solution moves the attachment point from the corner connector (one-dimensional point attachment) to a distributed receptacle structure within the profile strip (two-dimensional area attachment). This dimensional change allows for greater overlap between the protective device and frame while maintaining installation simplicity through the receptacle's geometric design.
3Productivity
If conventional attachment methods are used, then the protective device can be assembled, but sealing efficiency is inadequate due to play and reduced overlap
Solution Approach 1:
By merging the retaining element with the profile strip into a unified structure, the invention eliminates gaps and play that compromise sealing. The integrated construction ensures continuous contact between the protective device and frame, maintaining both assembly capability and superior sealing efficiency through a single monolithic component rather than separate attached parts.
Solution Approach 2:
The invention extracts the retaining element from its conventional attachment location (corner connector) and repositions it within the profile strip structure. This extraction and repositioning eliminates the play and reduced overlap associated with corner connector attachment, thereby improving sealing efficiency while preserving assembly capability through the dedicated receptacle design.
