Window Drive End Cap Integration for Compact Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window drives face challenges in being space-saving, installation-friendly, and efficient due to complex end cap arrangements with plug-in connections, which increase the drive's length and complexity.
Innovation Solution
A simplified drive system featuring an end cap that securely mounts on the drive unit's housing using a closure plate and threaded pins, facilitating easy electrical connection and installation, while allowing strain relief and access to connection terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex end cap arrangement with plug-in connection is used, then electrical connection is achieved, but the drive's length and complexity increase
Solution Approach 1:
The patent combines the end cap and the electrical connection elements into a single integrated component. The plug-in connection is built directly into the end cap structure, eliminating the need for separate connection mechanisms. This merging reduces the overall number of parts and simplifies the assembly while maintaining reliable electrical connectivity between the drive unit and the control system.

3Ease of manufacture
If a simplified end cap design is used, then installation is easier and space is reduced, but mounting security and structural stability may be compromised
Solution Approach 1:
The end cap is designed with a closure plate that can be separately engaged with the housing. This segmentation allows the end cap to be installed in two distinct steps: first inserting the main body, then securing the closure plate. This modular approach simplifies the installation process while ensuring robust mounting security through the separate engagement mechanism.
Solution Approach 2:
The closure plate is engaged with the housing in a direction substantially perpendicular to the insertion direction of the end cap. This dimensional change in the engagement approach allows for secure mounting without increasing the insertion complexity, as the perpendicular engagement provides structural stability while maintaining ease of installation.
4Strength
If the closure plate is engaged in a direction perpendicular to the insertion direction, then mounting security is improved, but the installation process becomes more complex

AI summary
The drive (1) has a drive unit (5) for moving the wing against a fixed blind frame (3) by a drive element (6). The drive unit is fixed to the wing or the blind frame by a holder. An end cap is designed to be arranged in a housing of the drive unit on the front side in a direction. The end cap is fixed in the housing by the engagement of a closure plate in a recess in the housing in another direction perpendicular to the former direction. A bar is arranged on the end cap, on which a threaded pin is supported. An independent claim is included for a method for mounting an end cap on a drive unit of a drive for a wing of a window.
