Protective Frame Mounting for Larger Window Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insect screen devices face challenges in achieving a sufficient overlap with window frames due to limited mounting areas and complex installation processes, leading to alignment issues and reduced flexibility in frame size adjustment.
Innovation Solution
A protective device with a mounting device featuring a fastening element that can be clipped onto a clamping design of the frame struts, allowing attachment at any point and enabling a larger overlap with the window frame, and comprising adjustable frame struts with channels or projections for telescopic extension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mounting elements are arranged in the outer corner area of the tension frame, then the hanging element can engage behind the window frame, but only a relatively small area of the tension frame is available for overlap with the window frame
Solution Approach 1:
The mounting element is designed with a multi-dimensional structure that extends beyond the plane of the tension frame. The mounting element includes a mounting body that protrudes from the tension frame plane, allowing engagement in multiple spatial dimensions while maximizing the overlap area within the frame plane.
2Ease of manufacture
If mounting elements are inserted into profile strips from an end face before corner connectors are mounted, then mounting elements can be positioned in undercut designs, but precise alignment may not be possible afterwards or additional securing means are required
Solution Approach 1:
The mounting elements are pre-positioned in the profile strips at the correct locations before the corner connectors are assembled. The profile strips are designed with guide features that ensure proper alignment of the mounting elements during this preliminary installation phase, eliminating the need for additional securing means.
3Ease of operation
If a separate groove with teeth is designed into the profile strip for the retaining claw, then the mounting element can be inserted directly into the profile strip, but the specific groove design limits compatibility with other profile strips
Solution Approach 1:
The mounting element is designed with a universal interface that can engage with various profile strip designs. The mounting body includes adaptable engagement features that can interface with different groove and tooth configurations, allowing the same mounting element to be used across multiple profile strip types without modification.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy installation and increased overlap with window frames, providing flexibility in frame size adjustment and improved mounting stability.
Implementation Method 1
the fastening element is elastically deformed and, at the end of the clipping process, elastically springs back, thus engaging at least a section of the clamping element
