Sealing Device One-Handed Mounting Fastener
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door and window sealing devices are difficult to assemble manually, requiring manual handling of screws, which complicates the installation process and can lead to misalignment or damage during assembly.
Innovation Solution
A sealing device with a housing rail and a fastening means featuring a plate with a through opening for a screw, where a retaining means, such as arms or a retaining ring, holds the screw in place, allowing for pre-assembly and one-handed assembly, using commercially available screws and ensuring proper alignment and secure fixation without manual handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual handling of screws is required for assembly, then the fastening can be securely achieved, but the assembly process becomes difficult and complicated
Solution Approach 1:
The screw is pre-assembled into the fastening bracket before installation, so that during installation only the bracket needs to be mounted without manually handling the screw separately. This preliminary assembly action simplifies the installation process and eliminates the need for manual screw handling during assembly.
Solution Approach 2:
The retaining means acts as an intermediary component between the screw and the fastening bracket, automatically holding the screw in place without requiring manual intervention. This intermediary mechanism ensures the screw remains securely positioned during the assembly process.
2Manufacturing precision
If manual handling of screws is required, then precise alignment can be achieved, but misalignment and damage risks increase during assembly
Solution Approach 1:
The retaining means automatically performs the alignment function without requiring manual positioning. The screw is self-held in the correct position by the retaining means, eliminating the risk of misalignment caused by manual handling and reducing the potential for damage during assembly.
3Productivity
If traditional fastening methods are used, then secure fixation is achieved, but the assembly process requires two hands and is time-consuming
Solution Approach 1:
The screw is pre-assembled into the bracket before installation, so that during installation only the bracket needs to be mounted with a single hand. This preliminary action eliminates the need for a second hand to hold the screw during assembly, significantly improving assembly speed and ease of operation.

AI summary
The invention relates to a seal device for a door or a window having a housing rail (30) and a sealing strip (31, 32) retained in the housing rail (30). The seal also has at least one fastener (1) for fastening the housing rail (30) to a door leaf or window sash (T) of the door or window, wherein the fastener (1) comprises a plate (10) for lying on an end face of the door leaf or window sash (T) and a passage opening (12) for a screw (2), which passage opening is arranged in the plate (10). A retaining element (14, 43) for retaining the screw (2) is present in the passage opening (12). Said seal device enables one-handed mounting of the retaining bracket on the door leaf and thus makes the mounting of the seal easier.
