Problem
Traditional paving brick installation is complex, expensive, and prone to poor drainage and soil-water conservation issues, with existing interlocking brick assemblies requiring multiple steps and types of bricks for assembly.
Innovation Solution
An interlocking paving brick assembly comprising a protruding brick with a tenon structure and a recessing brick with a mortise structure, designed for fast and convenient assembly, featuring anti-slip surfaces and drainage holes for improved stability and water management, using materials like polyethylene and calcium carbonate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional paving brick laying process is used, then base layer laying, leveling, floor tile laying, caulking, and surface cleaning can be completed, but the installation process becomes complicated and time-consuming
Solution Approach 1:
The paving brick is divided into modular units with distinct functional zones: a base layer engagement structure at the bottom for mechanical interlocking, and a top surface with anti-slip portions and drainage holes for surface functionality. This segmentation allows each module to be independently manufactured and quickly assembled, eliminating the need for complex multi-step installation processes while maintaining high productivity
Solution Approach 2:
Multiple functions are merged into a single brick structure: the base layer engagement structure combines leveling and anchoring functions, the top surface integrates anti-slip portions and drainage holes for both safety and water management. This merging reduces the number of separate components and installation steps, directly addressing the complexity issue while preserving installation speed
2Reliability
If traditional paving brick is used, then covering area can be achieved, but installation quality is hard to guarantee
Solution Approach 1:
The base layer engagement structure features a substantially flat bottom surface that creates an equipotential interface with the base layer, ensuring uniform contact and consistent mechanical interlocking across all bricks. This design guarantees reliable installation quality by eliminating variations in contact pressure and alignment, while the modular nature maintains ease of operation
Solution Approach 2:
The interlocking structure between the base layer engagement structure and the base layer is designed to self-align and self-lock during installation. The mechanical interlocking features automatically engage when bricks are placed, providing self-verifying installation quality without requiring skilled labor or complex tools, thus maintaining ease of operation while ensuring reliability
3Adaptability or versatility
If traditional paving brick structure is used, then covering and support functions are provided, but drainage and soil-water conservation are poor
Solution Approach 1:
The top surface incorporates drainage holes that create a porous structure, allowing water to pass through the brick body and reach the base layer for drainage. This porous design enables efficient water management while the overall brick structure maintains structural strength through its interlocking geometry and material composition
Solution Approach 2:
Different regions of the brick are assigned different properties: the top surface has anti-slip portions and drainage holes for water management and safety, while the base layer engagement structure has a flat bottom and interlocking features for structural strength. This local differentiation allows the brick to excel in both drainage functionality and structural strength simultaneously
4Productivity
If fast assembly is achieved with interlocking bricks, then large areas can be covered quickly, but assembly complexity increases
Solution Approach 1:
The base layer engagement structure serves multiple functions simultaneously: it provides mechanical interlocking with the base layer, ensures proper leveling, and facilitates quick assembly through its standardized interface. This multi-functionality in a single structure allows fast assembly of large areas while avoiding the need for multiple complex components

AI summary
An interlocking paving brick assembly comprises a protruding brick (10) and a recessing brick (20). The protruding brick is a block and comprises a first top portion (11) and four first sidewalls (12). Every angle between each of the first sidewall and the first top portions is a right angle, each of the first sidewall comprises a tenon structure (13). The recessing brick is a block, including a second top portion (21) and four second sidewalls (22). Every angle between each of the second sidewall and the second top portions is a right angle, and each of the second sidewall comprises a mortise structure (23). The tenon structure of the protruding brick and the mortise structure of the recessing brick is structurally complementary to each other, so the protruding brick and the recessing brick can be connected by the tenon structure and the mortise structure to form the interlocking paving brick assembly.
