L-Shaped Bracket Attachment for Building Member Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting building components, such as headers and vertical members, face challenges in providing strong and efficient connections that minimize the number of connectors while being easily installable, especially in applications where substantial loads are involved, and require a design that is cost-effective and suitable for both skilled and unskilled installers.
Innovation Solution
A metal attachment featuring a plate with L-shaped brackets and offset tabs that project at an angle, allowing for secure connection of building members by extending across aligned surfaces and using fasteners to secure the attachment to the members, with optional additional L-shaped brackets for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple connectors are used to ensure strong connections, then connection strength is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent combines multiple connection functions into a single integrated attachment device. The attachment includes a plate with multiple L-shaped brackets that can connect to different building members simultaneously, eliminating the need for multiple separate connectors while maintaining strong structural connections.
Solution Approach 2:
The attachment device is designed with universal applicability to connect various building members (headers, studs, joists, etc.). The L-shaped brackets can be configured in different orientations and the plate can accommodate multiple connection points, allowing one device to perform the function of multiple specialized connectors.
2Reliability
If traditional connection methods are used, then connection reliability is improved, but installation time and labor skill requirements increase
Solution Approach 1:
The attachment device is pre-configured with L-shaped brackets and mounting holes in specific patterns that anticipate common connection scenarios. This preliminary design allows installers to quickly adapt the device to different situations without requiring complex on-site fabrication or specialized skills, reducing installation time while maintaining reliability.
Solution Approach 2:
The attachment is divided into modular components (plate and L-shaped brackets) that can be independently positioned and secured. This segmentation allows for flexible installation where each component can be attached separately to different members, simplifying the installation process while ensuring reliable connections through multiple attachment points.
3Strength
If more connectors are used to ensure adequate connection, then connection strength is improved, but cost increases
Solution Approach 1:
The patent merges the functions of multiple connectors into a single attachment device, reducing the total quantity of connectors needed. The integrated design with multiple L-shaped brackets provides equivalent or superior connection strength while using fewer individual components, thereby reducing material costs.

AI summary
An attachment is provided for connecting two building members together such as a header and an adjoining support member. The attachment includes a plate having an engaging surface for extending across and in engagement with the two building members. At least one L-shaped bracket projects from the plate. The L-shaped bracket includes first and second tabs that form an angle of approximately 90° and which are offset with respect to the plate. The first and second tabs as well as the plate are adapted to be secured to the two building members.
