Construction Tie for U-Channel Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for securing U-channels for motorized retractable screens to façade building materials covering columns result in instability due to gaps between the façade material and the U-channel, necessitating additional costly wood framing and lacking a secure, hidden installation solution.
Innovation Solution
A construction tie with a U-shaped clip and adjustable flanges that securely engages the U-channel and façade material, allowing for hidden installation and enhanced stability, featuring a design that can be easily located using magnetic detection for non-ferrous materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional methods are used to secure U-channels to façade materials, then installation is simpler, but stability and structural integrity deteriorate due to gaps between façade material and U-channel
Solution Approach 1:
The construction tie is divided into distinct functional segments: a clip portion for engaging the U-channel, a bridge portion for spanning the gap, and flange portions for securing to the façade material. This segmentation allows each part to perform its specific function optimally while working together as an integrated system to eliminate gaps and improve stability.
Solution Approach 2:
The construction tie extends into the third dimension by projecting flange portions laterally from the bridge portion, creating a multi-dimensional structure that can engage both the U-channel and the façade material simultaneously. This dimensional extension allows the tie to bridge the gap between components in different spatial planes, securing the assembly firmly without leaving gaps.
2Strength
If wood framing is added to ensure stability, then structural integrity improves, but cost and device complexity increase
Solution Approach 1:
The construction tie merges multiple functions into a single integrated component: it provides structural support, eliminates gaps, secures the U-channel to the façade material, and replaces the need for separate wood framing. This consolidation achieves the same structural integrity as wood framing would provide, but with a more efficient, cost-effective, and less complex solution.
Solution Approach 2:
The construction tie serves multiple purposes simultaneously: it acts as a structural support element, a gap-eliminating bridge, a mounting mechanism for the U-channel, and a securing device for the façade material. This multi-functionality replaces what would traditionally require multiple separate components including wood framing, thereby reducing overall complexity while maintaining strength.
3Ease of manufacture
If construction ties are made from non-ferrous materials for aesthetic reasons, then visibility is reduced, but detectability during installation becomes difficult
Solution Approach 1:
The construction tie exhibits different material properties in different locations: the portions visible through façade materials are made from aesthetically pleasing non-ferrous materials, while specific detection portions incorporate ferromagnetic materials that enable easy detection with magnetic tools. This local differentiation of material quality allows the tie to satisfy both aesthetic requirements and installation detectability needs simultaneously.
4Adaptability or versatility
If adjustable flanges are provided for different façade materials, then adaptability improves, but manufacturing complexity increases
Solution Approach 1:
The flange portions are designed to be adjustable and adaptable to different orientations and configurations depending on the specific façade material being used. This dynamic capability allows the same construction tie design to accommodate various façade materials and installation scenarios without requiring entirely different tie designs, achieving versatility while maintaining relatively simple manufacturing processes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The construction tie provides increased stability to columns by securing U-channels to façade materials, eliminating the need for internal wood framing and ensuring a secure, hidden installation, while allowing for easy detection and installation, thus enhancing the structural integrity and aesthetic appeal.
Implementation Method 1
The construction tie may include a magnetic portion that allows for easy detection and location through the use of magnetic detection tools

AI summary
A construction tie for securing vertical U-channels of a motorized retractable screen unit to surrounding building material, such as brick, stone, or stucco. The tie includes a U-shaped clip that closely conforms to the shape of the U-channel. One or more flanges extend laterally from the clip to overlie the adjacent bricks. A plurality of these ties may be spaced vertically along the length of the U-channel. Once the brick façade is complete, the ties are not visible. Making the ties out of magnetically detectable material allows for locating their positions. The number of flanges may vary; one may extend from each side of the clip, or a single flange may extend rearwardly from the back of the base. A method of installing a screen unit may include the use of the inventive construction ties. A kit for installing the screen unit may include a plurality of the ties.
