Modular Building Connector Assembly to Prevent Interface Flexion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Expanding the footprint of pre-existing modular buildings by connecting additional modular units poses challenges in maintaining structural strength and avoiding flexion at the interface, as existing connector assemblies struggle to effectively link corner connectors across multiple levels and floors.
Innovation Solution
A connector assembly comprising upper and lower connectors with gusset plates, featuring arms and bosses for secure fastening, and a method for coupling these components to form a stable and strong connection between modular units and existing buildings, allowing for expansion while maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing connector assemblies are used to link corner connectors across multiple levels and floors, then the modular building can be expanded, but structural strength is compromised and flexion occurs at the interface
Solution Approach 1:
The connector assembly is divided into separate upper and lower connectors that can be independently positioned and secured to corner connectors at different levels. This segmentation allows each connector to be optimally designed for its specific location, maintaining structural strength while enabling expansion across multiple floors.
Solution Approach 2:
The solution extends the connection system into the vertical dimension by incorporating upper connectors that link to corner connectors on upper floors, in addition to lower connectors for ground level. This multi-dimensional approach maintains structural integrity while enabling vertical and horizontal expansion.
2Adaptability or versatility
If existing connector assemblies are used to link corner connectors, then modular units can be connected, but flexion occurs at the interface
Solution Approach 1:
The upper and lower connectors are designed with pre-positioned attachment points and alignment features that ensure proper positioning before final securing. This preliminary action prevents misalignment and flexion at the interface during operation.
Solution Approach 2:
The upper and lower connectors act as intermediary elements between the modular units and the existing building structure. These intermediaries provide stable connection points that distribute loads evenly, preventing flexion at the interface between different structural components.
3Strength
If additional bracing frames are added to prevent flexion, then structural strength is improved, but device complexity increases
Solution Approach 1:
The upper and lower connectors are integrated into a unified connector assembly that combines multiple functions: connection to corner connectors, load distribution, and alignment. This merging eliminates the need for separate bracing frames while maintaining structural strength.
Solution Approach 2:
The connector assembly serves multiple functions simultaneously: it connects modular units to existing structures, provides structural support, prevents flexion, and enables future expansion. This multi-functionality replaces the need for additional specialized bracing components, reducing overall system complexity.

AI summary
A connector assembly, having an upper connector coupled to a lower connector and a gusset plate sandwiched between the upper and lower connectors. The upper and lower connectors allow for coupling to adjacent upper and lower connectors, respectively, allowing for addition of a modular unit to a pre-existing modular structure. Also, ways of coupling adjacent upper connectors and coupling of adjacent lower connectors when coupling a modular unit to a pre-existing modular structure are provided.
