High Capacity Beam Hanger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concealed hangers for connecting headers and beams often lack resistance to tension and compression loading, and gravity loads, while also being difficult to install and adapt to modern building practices, and may not be fully hidden from view.
Innovation Solution
A two-piece connector made from metal with a longitudinal axis, featuring projections and slots that engage at an acute angle, providing resistance to bending and incorporating angled fasteners for enhanced stability and ease of installation, ensuring the connector is hidden from view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional concealed hangers are used to connect headers and beams, then the connection is hidden from view, but the hangers lack resistance to tension and compression loading
Solution Approach 1:
The connector is divided into two separate members: a first member with a slot and a second member with a projection. This segmentation allows each member to be optimized for specific functions - the slot provides flexibility and engagement, while the projection provides structural support and load resistance, together achieving both strength and concealment without excessive complexity
Solution Approach 2:
The projection of the second member fits within the slot of the first member, creating a nested configuration. This nesting allows the connector to maintain a compact, concealed profile while the interlocking geometry provides mechanical strength against tension and compression loads
2Ease of operation
If existing concealed hangers are designed, then they may be hidden from view, but they are difficult to install and adapt to modern building practices
Solution Approach 1:
The slot and projection design allows for dynamic adjustment during installation. The slot can accommodate variations in positioning and alignment, making the connector adaptable to different installation scenarios and modern building practices while maintaining ease of installation through simple engagement
Solution Approach 2:
The connector design serves multiple functions: it provides structural connection, resists various loads (tension, compression, gravity), enables easy installation through simple engagement, and adapts to different building practices. This multi-functionality achieves both ease of operation and adaptability
3Stability of the object's composition
If traditional hangers are used, then connection between members is achieved, but there is significant movement between the members
Solution Approach 1:
The slot and projection are designed to engage in a predetermined manner that pre-establishes stable positioning. The geometry of the slot and projection is configured to naturally align and lock the members together, minimizing movement before any additional fastening or securing is applied

AI summary
A connector joins a beam to a header, the connector has two members with mating portions. The mating members are provided with projections and slots that engage each other and transmit gravity loads between the members.
