Roller Blind Corner Bracket Integration for Frame Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window blind systems require multiple parts for installation, making the process complex and increasing the number of components needed, which can complicate the mounting process within a frame.
Innovation Solution
The integration of corner brackets from the frame into the window blind apparatus, where the first corner bracket is coupled to a control apparatus and the second corner bracket includes an idle end spindle, with a frame forming element covering the roller tube, allowing the brackets to support both the blind and frame components, and utilizing engagement elements for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional window blind systems are used with separate frame and blind components, then the frame can provide structural support, but the number of parts increases and installation becomes complex
Solution Approach 1:
The patent combines the frame corner brackets with the blind control apparatus into a single integrated component. The corner bracket serves dual functions: providing structural support for the frame and housing the control apparatus (clutch, sprocket, chain) for operating the blind. This merging eliminates the need for separate mounting brackets and control mechanisms, thereby reducing the total number of parts while maintaining both structural support and operational functionality.
Solution Approach 2:
The corner bracket is designed as a multi-functional component that simultaneously performs structural support, control apparatus housing, and blind mounting functions. By making the corner bracket universal in its capabilities, the system reduces component count without compromising the frame's structural integrity or the blind's operational control.
2Adaptability or versatility
If multiple separate components are used for frame and blind mounting, then each component can be optimized for its specific function, but the installation process becomes more complex and time-consuming
Solution Approach 1:
By merging the frame corner bracket and blind control apparatus into a single integrated unit, the patent reduces the number of installation steps. The integrated component is installed as one unit rather than requiring separate mounting of brackets, control mechanisms, and mounting hardware, thereby significantly reducing installation time while maintaining functional optimization through the multi-functional design.
3Strength
If the corner brackets are used solely for frame support, then the frame structure remains simple, but additional mounting hardware and parts are required for the blind apparatus
Solution Approach 1:
The corner bracket is designed to serve multiple functions simultaneously: it provides structural support for the frame, houses the control apparatus (clutch, sprocket, chain), and serves as the mounting point for the blind. This multi-functionality eliminates the need for additional mounting hardware and reduces the total component count while maintaining robust frame support.
