Multi-Angled Plate Fastening Device for Damage-Free Window Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening methods for functional devices on windows and doors often result in permanent damage, inadequate resilience, and chemical reactions that cause unintended damage to the sash or frame, especially when using screws or adhesives.
Innovation Solution
A fastening device with a multi-angled plate featuring an anchoring section with openings for screws, designed to be attached to the outer or inner circumference of the sash or frame, allowing secure and resilient attachment without visible damage, using existing screw channels and avoiding direct screwing into the sash or frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fasten functional devices directly to the sash or frame, then strong and secure fastening is achieved, but permanent visible damage is caused to the window or door
Solution Approach 1:
The fastening device is divided into two separate sections: an anchoring section that is screwed to the sash or frame, and a coupling section that couples the functional device. The anchoring section is positioned in the gap between the sash and frame, so that the fastening screws are hidden from both inside and outside views, while still providing strong anchoring.
Solution Approach 2:
The anchoring section acts as an intermediary element between the sash/frame and the coupling section. It transfers the fastening force from the hidden anchoring point to the functional device, enabling strong fastening without direct visible screwing on the window or door surfaces.
2Object-affected harmful factors
If adhesive is used to fasten functional devices, then no visible damage is caused, but the fastening strength is insufficient and adhesive residue removal is cumbersome
Solution Approach 1:
The invention replaces the chemical bonding mechanism of adhesives with a mechanical fastening system using screws. The anchoring section provides strong mechanical anchoring in the gap between sash and frame, eliminating the need for adhesives and their associated problems with weak bonding and difficult residue removal.
3Object-affected harmful factors
If hooks are used to attach functional devices, then no damage is caused, but the fastening is not very strong
Solution Approach 1:
The fastening device separates the anchoring function (providing strength) from the coupling function (connecting to device). The anchoring section with screws provides strong fastening, while the coupling section interfaces with the functional device, allowing strong attachment without direct hooking on visible surfaces.
Solution Approach 2:
The anchoring section utilizes the third dimension by positioning itself in the gap between the sash and frame, rather than attaching only to the two-dimensional visible surfaces. This allows strong anchoring in an otherwise unused spatial zone.

AI summary
The invention relates to a fastening device for attaching a functional device to a window or door that has a movable sash and a fixed frame or block. The fastening device has an anchoring section designed and intended to be screwed to the outer end face of the sash or to the inner end face of the frame or block such that, when the window or door is closed, the anchoring section is located in the space between the sash and the frame or block. The fastening device also has a coupling section, which has at least one fastening element for coupling the object to be fastened and which is connected to the anchoring section and is designed and intended to be attached when the window or door is closed.to be located outside the space between the sash and the frame or block of the closed door.
