Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional cement mortar walls are constructed using molds and reinforcing bars, then structural strength is achieved, but efflorescence occurs causing exterior wall staining and requiring additional coating maintenance
Solution Approach 1:
The wall structure is segmented into modular building blocks with standardized dimensions (e.g., 400mm x 200mm x 200mm). Each block is pre-formed with integrated reinforcing bar placement grooves and coupling portions, eliminating the need for traditional mold construction and cement mortar application. This segmentation prevents efflorescence by avoiding cement mortar exposure on exterior surfaces while maintaining structural strength through the interlocking block system.
Solution Approach 2:
The harmful cement mortar material is extracted from the exterior wall construction process. Instead of using cement mortar for wall formation and plastering, the invention uses pre-formed building blocks with integrated reinforcing structures. This extraction eliminates the source of efflorescence while the reinforcing bars and coupling portions provide the necessary structural strength.
2Reliability
If traditional brick or block laying methods are used with plastering, then wall structure is formed, but extensive time and skilled labor are required increasing construction cost
Solution Approach 1:
The building blocks are pre-formed with integrated reinforcing bar placement grooves, coupling portions, and leakage preventing recesses before construction. This preliminary action eliminates the need for skilled workers to perform complex mortar application and bricklaying techniques during construction. Workers simply need to assemble the pre-configured blocks, dramatically reducing construction time while maintaining reliable wall structure.
Solution Approach 2:
The building blocks are designed to be self-assembling through standardized concavo-convex coupling portions that automatically align and connect blocks. The reinforcing bars are pre-positioned in grooves within each block, and the blocks themselves provide the structural framework without requiring additional plastering or finishing work. This self-service design enables non-professionals to construct reliable walls quickly.
3Reliability
If traditional multi-stage construction processes are employed, then complete building structures are achieved, but additional materials are wasted and heavy-weight materials increase structural load
Solution Approach 1:
The building blocks serve multiple functions simultaneously: they provide the primary wall structure, contain integrated reinforcing bar placement grooves, include coupling portions for interlocking, incorporate leakage preventing recesses, and eliminate the need for separate plastering or finishing materials. This multi-functionality reduces material waste by consolidating multiple construction elements into a single component while maintaining reliable building structure.
Solution Approach 2:
The invention merges traditionally separate construction elements (wall blocks, reinforcing bar supports, coupling joints, and finishing surfaces) into a single integrated building block. This consolidation eliminates the need for multiple construction stages and reduces material waste from mortar, plaster, and separate reinforcement components while achieving complete and reliable building structures.
4Ease of manufacture
If cement blocks or bricks are used for wall construction, then walls can be built, but cracks and leakage occur over time due to building load
Solution Approach 1:
The building blocks utilize composite construction combining rigid block materials with integrated metal reinforcing bars placed in pre-formed grooves. The coupling portions create interlocking joints that distribute building loads across multiple blocks. This composite approach prevents cracks and leakage by reinforcing the block structure internally and creating continuous load paths through the wall assembly, significantly improving wall durability while maintaining ease of construction.
Solution Approach 2:
The coupling portions extend beyond the simple face-to-face joining of traditional blocks, creating three-dimensional interlocking structures that engage blocks in multiple directions. The reinforcing bar grooves provide additional dimensional stability by anchoring reinforcement that spans across block joints. This multi-dimensional connection system prevents cracking and leakage under building loads while keeping the construction process simple.

AI summary
The present invention relates to a building block serving as a mold when carrying out civil engineering and construction works and forming an external appearance of a structure, a building structure and a method of bricking a wall using the same. The building block comprises first and second exterior walls facing each other and spacing from each other in back and forth directions, and a connecting portion connecting the first and second exterior walls to each other and having an upper portion provided with a first mounting groove for mounting a width-directional reinforcing bar. Here, concavo-convex coupling portions are formed at inner peripheries of the first and second exterior walls, for concavo-convexly coupling to each adjacent block, and here, leakage preventing recesses are respectively formed at outer peripheries of the first and second exterior walls.
