Modular Load Bearing System for Residential Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional load bearing systems for residential structures often require extensive framing, leading to increased construction time and costs, and struggle to efficiently integrate load-bearing columns into walls without compromising structural integrity or aesthetics.
Innovation Solution
A modular load bearing system comprising prefabricated structural columns with hollow-section members and internal bracing, paired with prefabricated beams and cladding panels, which allows for a ring-like configuration that supports both external and internal cladding, reducing the need for traditional framing systems and enabling rapid construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional load bearing systems use extensive framing, then structural integrity is maintained, but construction time and costs increase
Solution Approach 1:
The structure is divided into discrete, prefabricated columns with standardized dimensions and connection details. Each column is a self-contained load-bearing element that can be manufactured off-site and assembled quickly, eliminating the need for extensive on-site framing while maintaining structural integrity through precise segmentation and connection design.
Solution Approach 2:
Columns are prefabricated in advance with pre-attached bracing elements and connection hardware. The hollow-section members are manufactured to exact specifications before delivery to the construction site, allowing for rapid installation without the time-consuming process of assembling framing members on-site, thus reducing construction time while preserving structural strength.
2Shape
If columns are integrated into walls, then aesthetic appeal improves, but structural integrity may be compromised
Solution Approach 1:
The column structure is nested within the wall assembly, with hollow-section columns positioned inside the wall cavity. Bracing elements are nested within the hollow sections, and cladding panels are attached to the exterior. This nested arrangement allows columns to be visually concealed or integrated into the wall aesthetic while maintaining their full structural capacity internally.
Solution Approach 2:
Different portions of the column system serve different functions: the hollow-section members provide structural strength and stiffness, internal bracing elements provide lateral stability, and external cladding panels provide aesthetic finish. This differentiation of local qualities allows each component to be optimized for its specific function while working together as an integrated wall system.
3Productivity
If prefabricated components are used, then construction speed increases, but manufacturing complexity increases
Solution Approach 1:
The hollow-section columns are designed as universal components that can serve multiple functions: primary load-bearing elements, lateral bracing anchors, cladding support structures, and integration points for building services. This multi-functionality reduces the total number of different component types needed, simplifying manufacturing processes while enabling rapid construction through standardized, versatile elements.

AI summary
Disclosed is a load bearing system for a residential structure. The load bearing system comprises two or more structural load bearing columns, at least one beam extending between and connected with respect to in-use upper ends of the two or more structural load bearing columns, and at least one cladding panel mounted to extend between a foundation of the residential structure and the at least one beam. The columns are mounted to a foundation of the residential structure in spaced relation to the or each other column and comprise a periphery defined by hollow-section members and one or more internal bracing elements extending between the hollow-section members.
