Window Drive Housing Exit Guide Fixing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive units for windows and similar applications require complex clamping devices to fix chain drives, making assembly cumbersome and time-consuming, especially for large and heavy wings that need multiple drives.
Innovation Solution
A drive housing designed as a hollow profile with guides and webs to accommodate multiple drives, featuring recesses for actuating elements and an exit guide for secure positioning, where an exit element is used to fix the drive within the housing, reducing assembly complexity and facilitating easy sliding of the actuating element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex clamping device is used to fix the chain drive in the housing, then the drive can be securely positioned, but the assembly process becomes cumbersome and time-consuming
Solution Approach 1:
The patent extracts the essential positioning function from the complex clamping device by introducing a simple exit element that engages with the exit guide. This exit element, combined with the recess in the housing, provides sufficient positioning without requiring complex clamping mechanisms, thus simplifying the overall device while maintaining reliability.
Solution Approach 2:
The patent segments the positioning function into separate components: the recess in the housing, the exit guide on the drive, and the exit element. This segmentation allows each component to perform its specific function independently, simplifying the assembly process while ensuring secure positioning of the drive.
2Productivity
If multiple drives are arranged in a common drive housing for on-site assembly, then assembly efficiency is improved, but the complexity of positioning and fixing each drive increases
Solution Approach 1:
The patent creates a universal positioning system that works for multiple drives within the same housing. The recess and exit guide configuration is standardized, allowing the same positioning mechanism to be applied to each drive, thereby reducing the overall complexity of positioning and fixing multiple drives while maintaining high assembly efficiency.
3Ease of operation
If the recess is made larger to facilitate actuating element passage, then assembly is easier, but the stability of the drive housing is reduced
Solution Approach 1:
The patent applies local quality by creating a precisely sized recess that is only slightly larger than necessary for the actuating element to pass through. This localized precision ensures that the recess provides adequate passage while maintaining the overall stability of the drive housing, avoiding the need for larger openings that would compromise structural integrity.

AI summary
The drive (1) has an actuating element e.g. chain, pivoting a wing between an opened position and a closed position, where the drive is displaced in a drive housing (3). An opening (4) is clamped with the actuating element. The drive housing is formed as a closed rectangular hollow profile. The opening limits clamping of the actuating element at the hollow profile of the drive housing, so that the drive displaced in the hollow profile is fixed at the drive housing by a discharge element (6) inserted into the opening, where the drive comprises a discharge guide (5) for the actuating element.
