Roof Window Support Beams Eliminate Gap Trimmers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of roof window systems on inclined roof surfaces is complex and time-consuming due to the need for gap trimmers between window units, which complicates the process for both experienced and inexperienced installers.
Innovation Solution
A roof window system with a support assembly comprising horizontally mounted support beams that connect the top and bottom members of each window unit, eliminating the need for gap trimmers and simplifying the installation process by using mounting brackets that can be easily fastened to the roof structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If gap trimmers are used between window units to ensure structural support, then the strength and stability of the roof window arrangement is improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The patent combines the gap trimmer function with the support beam structure by integrating horizontal support beams that span across multiple window units. This merging eliminates the need for separate gap trimmers between adjacent windows, as the continuous support beam provides structural support for multiple units simultaneously, reducing overall component count and installation complexity while maintaining strength requirements
Solution Approach 2:
The support beams are designed to serve multiple functions: they provide structural support for window units, act as mounting surfaces for multiple windows, and eliminate the need for separate gap trimmers. This multi-functionality reduces the number of different component types needed in the system, simplifying both the device complexity and installation process
2Strength
If gap trimmers are installed between window units, then sufficient strength and support are provided, but the installation time increases
Solution Approach 1:
The support beams are pre-installed on the roof structure before the window units are mounted. This preliminary action creates ready-to-use mounting surfaces with pre-positioned fixing points, allowing window units to be quickly attached without the need to install separate gap trimmers between each window, thereby reducing installation time while maintaining structural support
3Stability of the object's composition
If multiple support beams are used to support window units, then structural stability is improved, but the aesthetic appearance and view obstruction worsen
Solution Approach 1:
The patent merges multiple support functions into continuous horizontal support beams that span across the roof structure. These beams are positioned strategically to provide structural stability while minimizing visual obstruction. The integration of support functions into fewer, more strategically placed elements reduces the number of visible vertical components compared to traditional gap trimmer configurations
