Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional building block systems, such as ICFs and EPS blocks, require large amounts of concrete, skilled labor, and fail to provide adequate water-tightness and structural support, while vertical panel systems are cumbersome and heavy, posing safety risks and inefficiencies in construction.
Innovation Solution
A modular building block system comprising foundation blocks and wall blocks with tapered surfaces for secure stacking, along with capping blocks and corner blocks, made from lightweight materials like expanded polystyrene, which can be easily assembled to form a structurally sound and water-tight structure using adhesives and reinforcing rods.

Engineering Contradiction Analysis
1Ease of manufacture
If conventional ICF blocks are used to build structures, then a simple concrete wall structure can be achieved without formwork, but large amounts of concrete material are required and highly skilled labor is needed
Solution Approach 1:
The patent uses composite building blocks made of lightweight materials (such as expanded polystyrene foam) combined with insulating layers and structural panels, replacing traditional concrete ICF blocks. This composite approach maintains the simplicity of wall construction while significantly reducing the quantity of heavy material required.
Solution Approach 2:
The patent changes the material parameters from heavy concrete to lightweight insulating materials, altering the density and weight characteristics of the building blocks. This parameter change enables easier handling and reduces material quantities while maintaining structural integrity through the multi-layer composite design.
2Weight of moving object
If conventional EPS blocks are assembled together, then a lighter weight structure is achieved, but adequate seal against water infiltration is not achieved
Solution Approach 1:
The patent employs composite building blocks consisting of multiple layers including lightweight insulating material, structural panels, and integrated sealing layers. This multi-layer composite structure provides both the weight benefits of lightweight materials and the water-tightness through integrated sealing components at block interfaces.
Solution Approach 2:
The patent introduces intermediary sealing elements and bonding agents between the lightweight building blocks to create water-tight joints. These intermediary components fill the gaps and seams between blocks, preventing water infiltration while maintaining the overall lightweight character of the structure.
3Adaptability or versatility
If SIPs are used for building structures, then a composite building material with multiple functions is achieved, but heavy weight requires large machinery for handling and highly skilled labor is required
Solution Approach 1:
The patent divides the building structure into modular segments consisting of standardized building blocks with integrated functions. Each block is a self-contained unit with insulation, structural panels, and sealing components, making them easier to handle individually compared to large SIP panels while maintaining versatility across different building applications.
Solution Approach 2:
The patent uses composite building blocks that integrate multiple functions (structural support, insulation, sealing) within a single modular unit. This integrated composite approach reduces the need for separate heavy components and simplifies handling while maintaining the versatility needed for various building applications.
4Device complexity
If vertical panel systems are used, then a building structure can be formed, but the systems are complicated to install and require heavy machinery
Solution Approach 1:
The patent segments the building structure into small, lightweight modular blocks that can be easily handled and assembled by hand or with minimal equipment. This segmentation eliminates the need for heavy machinery required by vertical panel systems, while the modular nature simplifies the installation process through straightforward stacking and interlocking.
Solution Approach 2:
Instead of using large heavy panels that must be vertically installed, the patent inverts the approach by using small lightweight blocks that are assembled horizontally in stacked configurations. This inversion of the installation methodology eliminates the need for heavy machinery and complicated installation procedures while achieving the same structural result.

AI summary
A building system includes a foundation block and a wall block. Each block has opposing first and second main surfaces, a first top end and an opposing second bottom end, and opposing first and second side surfaces extending between the first and second main surfaces and between the top and bottom ends. Portions of the first and second main surfaces of the foundation block proximate the top end thereof taper axially inwardly toward each other and toward an interior of the block to form a pair of inwardly tapered surfaces. The bottom end of the wall block includes a pair of outwardly tapered surfaces which extend axially outwardly away from each other and toward an exterior of the wall block. The pair of outwardly tapered surfaces of the wall block engage the pair of inwardly tapered surfaces of the foundation block in an assembled configuration to form a first vertical stack member.
