Multi-functional Connector for Offsite Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing offsite construction methods lack a connector system that can efficiently connect multiple structural elements in orthogonal directions, limiting the versatility and speed of building assembly while increasing manufacturing and assembly complexity.
Innovation Solution
A connector block with buttress elements and a base plate that allows orthogonal connection of up to three structural elements, featuring L-shaped attachment elements, integrated nuts, and a U-bracket for secure handling and transportation, formed from metal plates with mortise and tenon joints for enhanced strength and simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single connector type is used for all structural element connections, then device complexity is reduced, but adaptability to different connection orientations is limited
Solution Approach 1:
The connector is designed with multiple location portions (first, second, and third location portions) that can receive structural elements in different orientations. The first and second location portions receive structural elements at transverse angles to each other, while the third location portion receives a structural element extending orthogonally. This multi-functional design allows a single connector type to accommodate various connection configurations, improving adaptability without increasing device complexity.
2Adaptability or versatility
If multiple connector types are used to accommodate different connection orientations, then adaptability is improved, but assembly time increases
Solution Approach 1:
By designing a single connector with multiple location portions capable of receiving structural elements in different orientations, the patent eliminates the need for multiple connector types. The first location portion receives structural elements at transverse angles, the second location portion receives structural elements at different transverse angles, and the third location portion receives orthogonally extending structural elements. This universal design streamlines assembly by reducing the variety of connectors that need to be selected and installed.
3Strength
If structural elements are connected manually without attachment elements, then device complexity is reduced, but connection strength is insufficient
Solution Approach 1:
The patent introduces attachment elements as intermediary components between the connector and structural elements. These attachment elements are configured to connect to the structural elements and provide enhanced connection strength. The attachment elements act as mediators that bridge the connector and the structural elements, ensuring robust connections while maintaining manageable device complexity through standardized intermediary components.

AI summary
An assembly for offsite construction of a building, a connector for use in such an assembly, along with a method of manufacture of such a connector, and a method of construction using the assembly. The connector includes first and second buttress elements defining, respectively, a first location portion and a second location portion. The first location portion and the second location portion are configured, respectively, to receive first and second structural elements extending at transverse angles to each other. The first and second buttress elements each has first and second opposite side walls defining an access space between them for a connector to be accessed. The second side wall of the first buttress element and the second side wall of the second buttress element together define a third location portion configured to receive a third structural element extending transversely to the first and second structural elements.
