Solution Overview
Problem
Existing brick construction materials require skilled labor for installation and are labor-intensive, making them costly, and there is a need for improved insulation and aesthetic appeal in building materials.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional brick is used for exterior surfaces, then thermal resistance and structural strength are improved, but labor intensity and installation complexity increase significantly
Solution Approach 1:
The wall panel is divided into distinct functional layers: a structural cementitious core layer providing strength, an insulation layer providing thermal resistance, and a veneer layer providing aesthetic appearance. This segmentation allows each layer to be optimized independently and installed as a pre-assembled unit, eliminating the need for skilled brick masons to install individual bricks.
Solution Approach 2:
Multiple functions traditionally performed by separate components are merged into a single integrated wall panel: structural support, thermal insulation, and aesthetic cladding are combined into one pre-fabricated unit that can be installed as a complete assembly, reducing installation complexity while maintaining all required functions.
2Reliability
If traditional brick laying is used, then aesthetic appeal and durability are achieved, but labor costs and installation time increase
Solution Approach 1:
The wall panels are pre-fabricated with all layers (structural, insulation, and veneer) assembled before delivery to the construction site. The cementitious layer is cured, the insulation is attached, and the veneer is applied in advance, allowing rapid installation of complete wall sections without requiring skilled labor for on-site brick laying, thereby increasing installation speed while maintaining durability.
3Temperature
If brick is used as exterior siding, then thermal resistance is improved, but insulation performance and energy efficiency are insufficient
Solution Approach 1:
The wall panel uses a composite structure combining a cementitious structural layer with a dedicated insulation layer (such as rigid foam board or spray foam). This composite material approach provides superior thermal resistance compared to traditional brick alone, significantly reducing energy loss through the building envelope and improving overall energy efficiency.
4Adaptability or versatility
If brick is applied to existing building structures, then aesthetic renovation is achieved, but installation difficulty and cost increase
Solution Approach 1:
The wall panel is segmented into a thin structural cementitious layer, insulation layer, and veneer layer, allowing the entire assembly to be installed as a lightweight retrofit component over existing building structures. This segmentation enables installation on existing buildings without requiring complete demolition and reconstruction, improving retro-fit capability while maintaining ease of installation through pre-assembly.
