Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening solutions for winding shaft boxes to window or door frames are not highly compatible with various window or door frames, leading to complex and time-consuming installation processes.
Innovation Solution
A fastening arrangement featuring a connecting bracket with a clip adapter and a hinge joint, allowing for tool-free clipping onto counter-clip elements of the window frame, with optional screwing and use of different clip adapters for compatibility with diverse frame types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal brackets are used to fasten the winding shaft box to the window frame, then the connection strength is improved, but the installation time and complexity increase
Solution Approach 1:
The fastening system is divided into separate components: a connecting bracket attached to the winding shaft box, and a separate fastening element that attaches to the window frame. This segmentation allows the bracket to be pre-assembled with the box while the fastening element can be quickly attached or removed, reducing overall installation time while maintaining connection strength.
Solution Approach 2:
The connecting bracket is pre-assembled with the winding shaft box during manufacturing, including pre-drilled holes and pre-attached fastening elements. This preliminary preparation eliminates the need for on-site measurements, drilling, and complex assembly operations, significantly reducing installation time while ensuring proper alignment and connection strength.
2Ease of operation
If universal fastening solutions are used, then the installation process is simplified, but compatibility with various window frame types decreases
Solution Approach 1:
The connecting bracket is designed with multiple attachment configurations and adjustable features that enable it to accommodate different window frame types (wood, metal, vinyl, various profile shapes). The bracket can be mounted in different orientations and positions, providing universal compatibility while maintaining a simple, consistent installation process across all frame types.
3Stability of the object's composition
If the connecting bracket is permanently fixed to the winding shaft box, then the structural stability is improved, but the adaptability to different window frames decreases
Solution Approach 1:
The connecting bracket incorporates adjustable and reconfigurable features that allow it to adapt its configuration based on the specific window frame type. The bracket can be positioned at different angles, adjusted to different depths, and reconfigured to match various frame profiles, providing both structural stability through secure attachment and adaptability to different frame types.

AI summary
The invention relates to a fastening arrangement for attaching a winding shaft housing to a window or door frame, comprising a side part (1) of the winding shaft housing, which has a receptacle (5) for attaching a connecting bracket (3) that projects downwards beyond the side part (1) in its connected position, and the connecting bracket (3), which in the connected position is attached on its upper side to the receptacle (5) of the side part (1) and on its lower side to a vertical strut (2) of the frame. The connecting bracket (3) has a body formed from a flat strip, extending longitudinally overall or longitudinally on both sides of a bend in the same direction, with a lower end section attached to it that follows the course of the vertical strut (2) in the connected position.The fastening arrangement further includes a clip adapter (7) at the lower end section of the connecting bracket (3), which is provided with a number of clip elements (8) with which it is clipped to counter clip elements of the vertical strut (2) in the connecting position.
