Screen Mounting Assembly With Water-Deflecting Rib And Spacer Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window profile mounting systems for screen devices face issues such as water seepage, difficulty in accurately locating screw positions due to complex structures, and potential damage to thin walls when screws are tightly inserted.
Innovation Solution
A mounting assembly featuring a window profile with a slot at the top wall and a corresponding rib on the mounting base for precise alignment, a fastening plate with a tapering vertical rim to direct water away from screw holes, and a spacer sleeve to prevent wall damage during screwing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If screen guides are screwed directly to window profiles, then fastening is achieved, but openings are created that allow rainfall to seep into the window profile
Solution Approach 1:
A mounting base is introduced as an intermediary component between the screen guide and the window profile. This mounting base includes a fastening plate that can be securely attached to the window profile using screws, while the screen guide is then fastened to the mounting base at a distance from the window profile. This intermediary structure eliminates direct screw openings in the window profile, preventing water seepage while maintaining fastening functionality.
2Strength
If screws are tightly screwed into screw channels in window profiles with chamber formations, then fastening strength is improved, but the thin walls surrounding the chambers often get damaged
Solution Approach 1:
The mounting base serves as a mediator that distributes the fastening force. Instead of directly screwing the screen guide into the window profile (which concentrates force on thin walls), the mounting base provides a broader attachment surface. The screws are inserted into the mounting base rather than directly into the window profile's thin-walled chambers, reducing the risk of wall damage while maintaining adequate fastening strength.
3Manufacturing precision
If window profiles have specific structures with screw channels at specific locations, then fastening precision is improved, but it becomes difficult to accurately define and locate these specific places on site
Solution Approach 1:
The mounting base acts as an intermediary that simplifies on-site location and installation. Instead of requiring the fitter to precisely locate specific screw channels in the window profile, the mounting base provides a convenient attachment interface. The mounting base can be positioned and secured to the window profile at appropriate locations, and then the screen guide is fastened to the mounting base. This intermediary approach makes on-site installation more flexible and easier to perform accurately.
