Modular Building Connector Assembly for High-Load Force Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular building construction methods struggle to efficiently resist and transmit large moments, wind, and seismic forces, especially in slender or tall buildings, due to limitations in force transmission through conventional module connections and the need for additional structural elements.
Innovation Solution
A system of components and work methods that includes load-bearing connector blocks, gusset plates, and standardized reinforcing members, allowing for the efficient assembly and connection of modular frames to form buildings that can resist and transmit large forces without the need for extensive additional bracing or reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional pinned connections between modules are used, then ease of assembly is improved, but force transmission capability deteriorates
Solution Approach 1:
The connection system is segmented into multiple functional components: pinned connections for ease of assembly, plus additional reinforcing members and bracing elements that can be selectively added to enhance force transmission. This allows the system to provide both easy assembly through the pinned mechanism and improved strength through supplemental structural elements.
2Strength
If diagonal bracing is added to improve force transmission, then structural strength is improved, but device complexity increases
Solution Approach 1:
The connector blocks serve multiple functions: they provide pinned connections for easy assembly, incorporate reinforcing members for enhanced strength, and include integrated bracing capabilities. By combining these functions into a single universal connector assembly, the system achieves improved force transmission without proportionally increasing overall structural complexity.
Solution Approach 2:
The connector blocks are pre-assembled with reinforcing members and bracing elements integrated into the design before deployment. This preliminary configuration allows the complex structural elements to be installed as a unified assembly rather than requiring separate complex installation procedures, thereby reducing the perceived complexity during construction.
3Strength
If modules are reinforced to resist forces, then structural strength is improved, but manufacturing cost increases
Solution Approach 1:
Rather than uniformly reinforcing all modules throughout the entire structure, the reinforcing members and bracing elements are strategically positioned at critical locations where force transmission is most needed, such as at connection points and load-bearing interfaces. This localized reinforcement approach provides necessary strength while minimizing material usage and manufacturing costs.
4Strength
If additional bracing structures are added to transmit loads, then force transmission is improved, but the useful floor area decreases
Solution Approach 1:
The bracing elements and reinforcing members are nested within the existing module framework and connector blocks rather than being added as external protruding structures. The bracing integrates into the wall and floor assemblies, utilizing the existing structural envelope to provide load transmission paths that do not encroach upon the useful interior floor area.
