Structural Module Tie Assembly for Misaligned Modular Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction industry faces challenges in efficiently constructing high-rise buildings in limited spaces with increasing labor costs, requiring improved load support and faster interconnection of structural modules while minimizing the use of structural members.
Innovation Solution
The use of structural module ties with column-based load distribution, featuring tie rods and receivers that can be easily assembled into sockets, allowing for horizontal load transfer between modules, even when misaligned, and providing built-in tolerance for quick assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional structural members are used to support load in modular buildings, then structural stability is achieved, but the number of structural members increases and assembly complexity increases
Solution Approach 1:
The patent combines the tie rod and plate into an integrated tie assembly that functions as both a structural connector and a load-bearing element. The tie rod passes through the plate and is secured with nuts, creating a unified component that reduces the number of separate structural members needed while maintaining load support capability.
Solution Approach 2:
The tie assembly serves multiple functions: it connects adjacent modules, transfers loads between modules, and provides structural stability. This multi-functional design eliminates the need for separate dedicated load-bearing members, thereby reducing overall structural complexity.
2Reliability
If precise alignment features are implemented for module connection, then connection reliability is improved, but manufacturing complexity and assembly time increase
Solution Approach 1:
The plate features elongated slots instead of precise circular holes, changing the geometric parameter from a fixed-point connection to a linear-range connection. This allows for tolerance in alignment while maintaining connection reliability, and significantly reduces assembly time as modules can be connected without precise positioning.
Solution Approach 2:
The elongated slot design anticipates potential misalignment during assembly by providing a built-in tolerance range. This pre-accommodation of alignment variations eliminates the need for time-consuming adjustments or repositioning during assembly.
3Adaptability or versatility
If modular buildings are constructed with extensive on-site assembly, then flexibility in customization is achieved, but construction time and labor costs increase
Solution Approach 1:
The tie assemblies are pre-fabricated with integrated rods and plates, and modules are prepared with predetermined connection points during off-site manufacturing. This preliminary preparation enables rapid on-site assembly while maintaining customization flexibility, as the pre-configured connection systems can be quickly installed without extensive on-site fabrication.

AI summary
A structural module (1) has a structural frame having structural members forming floor plates (2), wall plates (3), vertical columns (4), braces (7) extending at angles from the columns to the floor plates, and wall studs. The columns and the braces are configured to transfer vertical loads without assistance from the studs. There may be a module-to-module tie (200) affixed to at least one column, and each tie may be affixed to a top surface of a column, to link columns of adjoining modules together in a horizontal plane, and to accommodate misalignment of the modules in the horizontal plane.
