Conventional building construction methods require skilled labor, are costly, and lack efficient insulation, making it difficult to construct affordable, resilient, and quickly assembled housing units, especially in areas with limited skilled labor and resources.
Innovation Solution
A composite building construction system featuring a frame, wallboard with both external and internal insulation, and a sprayed concrete layer, which provides structural strength and insulation without the need for skilled labor, using prefabricated frame sections and an automated alignment system for rapid assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional construction methods (wood stud, concrete block, or precast panel) are used, then structural strength is achieved, but skilled labor is required and construction cost increases
Solution Approach 1:
The construction system divides the building into modular precast concrete panels that can be independently manufactured and assembled. Each panel is a self-contained unit with integrated insulation and reinforcement, eliminating the need for skilled workers to perform complex on-site construction tasks while maintaining structural integrity through standardized connection details.
Solution Approach 2:
Insulation and reinforcement are pre-installed within the concrete panels during manufacturing before delivery to the construction site. This preliminary action eliminates the need for skilled workers to perform these tasks on-site, reducing labor skill requirements while ensuring proper installation quality and structural performance.
2Loss of energy
If insulation is placed only externally on the stud frame, then some insulation benefit is achieved, but sufficient heat and cold protection is not provided
Solution Approach 1:
The system merges external and internal insulation into a single integrated insulation layer within the precast concrete panel. The insulation is positioned between the exterior concrete surface and the interior finish, providing both external and internal thermal protection in one component, thereby achieving sufficient heat and cold protection without requiring separate insulation applications on both sides of the frame.
3Strength
If precast concrete panels are used with framing system, then structural strength is improved, but heavy equipment is required and construction complexity increases
Solution Approach 1:
The precast concrete panels serve multiple functions: they provide the primary structural load-bearing function, incorporate integrated insulation for thermal protection, and include built-in connection details for assembly. This multi-functionality eliminates the need for separate framing templates and reduces construction complexity while maintaining structural strength.
Solution Approach 2:
The complex framing template system is extracted and replaced by directly assembling the multi-functional precast panels using simplified connection details. The panels are designed to be connected directly to each other and to the foundation without requiring intermediate framing members, thereby reducing device complexity while preserving structural integrity.
4Productivity
If rapid construction is achieved with precast panels, then construction time is reduced, but heavy equipment and skilled workforce are still required
Solution Approach 1:
The building is segmented into standardized precast panels that can be manufactured off-site and delivered ready for assembly. This segmentation allows unskilled or semi-skilled workers to quickly assemble the panels using simple connection procedures, maintaining rapid construction speed while eliminating the need for large numbers of skilled workers.
Solution Approach 2:
The precast panels are designed with self-aligning features and self-contained connection details that enable workers to assemble them without requiring skilled judgment or complex procedures. The panels essentially guide their own installation, reducing the skill level needed while maintaining fast construction pace.

AI summary
A composite automated building construction system, with automated alignment of various truss and wall sections, includes a wall section having frame, an expanded wallboard, and a concrete layer. The wallboard includes an outer portion and inset portion wherein the wallboard is attached to the frame with the outer portion covering an exterior side of the frame and the inset portion is disposed within the frame. The wallboard thus provides exterior and interior insulation for the system. The concrete layer is sprayed on to the outer portion of said wallboard, forming a strong durable composite construction system. A building is constructed with these wall sections by way of a base form template delimiting the boundary of the building. The base forms are installed and then a concrete foundation slab is poured over the base forms. Pre-installed bolts extend above the concrete foundation to providing pre-determined mounting points for the frames for the wall sections.
