Window Screening Mounting Means for Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window screening arrangements face challenges in load distribution between the screening device and the sash, particularly with roller shutters, where wind and weight loads can impact the sash structure if not distributed suitably.
Innovation Solution
The solution involves a window design where the side rails of the screening device are mounted to the sash bottom member instead of the side members, using a hook section and engagement portion on the bottom sash covering, with fastening means cooperating exclusively with the pane holding devices for secure and controlled connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the side rails of the screening device are connected to the side members of the sash using traditional sliding or rolling mounting fittings, then the screening device can be installed and operated, but the load from wind and weight is not properly distributed and may significantly impact the sash structure
Solution Approach 1:
The patent introduces a mounting means as an intermediary component that connects the side rails to the sash bottom member. This mounting means includes a mounting block with engagement portions that interface with the side rails and a fixing portion that attaches to the sash bottom member through fastening means. This intermediary structure properly distributes loads from the screening device to the sash, preventing direct stress concentration on the side members while maintaining installation simplicity.
2Strength
If the mounting means is positioned on top of the bottom sash covering with engagement portion in engagement with the hook section, and fixed to the sash bottom member through pane holding devices, then the load distribution is improved and structural integrity is maintained, but the installation requires precise positioning and engagement steps
Solution Approach 1:
The mounting means is segmented into distinct functional portions: an engagement portion that interfaces with the hook section of the bottom sash covering, a mounting block body that provides structural support, and a fixing portion that attaches to the sash bottom member through pane holding devices. This segmentation allows each portion to be optimized for its specific function while maintaining overall simplicity in the mounting procedure through logical sequential steps.
3Ease of operation
If traditional mounting fittings are used that involve sliding or rolling movement, then installation can proceed with standard procedures, but the connection reliability and load transfer to the sash structure is compromised
Solution Approach 1:
The mounting means is designed to be pre-positioned on top of the bottom sash covering with the engagement portion brought into engagement with the hook section before final fixation. The fastening means are then introduced through the fixing portion to secure the mounting means to the sash bottom member through the pane holding devices. This preliminary positioning action ensures proper alignment and engagement before final securing, enhancing connection reliability while maintaining ease of operation through a logical sequential process.
