Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the surface of longitudinal and transversal bars is increased to improve reinforcement effectiveness, then the resistance to traction increases, but the volume of reinforcement materials increases
Solution Approach 1:
The invention transitions from traditional 3D volumetric reinforcement bars to 2D planar reinforcement elements (plates or sheets). This dimensional reduction allows significantly increasing the surface area of reinforcement within the same volumetric constraints of the concrete element, thereby improving traction resistance without proportionally increasing reinforcement volume.
Solution Approach 2:
The invention changes the geometric parameters of the reinforcement from cylindrical bars with limited surface-area-to-volume ratio to flat plates or sheets with dramatically increased surface area. This parameter transformation enables achieving higher reinforcement effectiveness with reduced material volume by optimizing the surface-area-to-volume ratio.
2Strength
If traditional reinforcement with longitudinal and transversal bars is used, then the reinforcement provides structural support, but the manufacturing process is time-consuming and expensive
Solution Approach 1:
The invention segments the traditional multi-component reinforcement system (longitudinal bars, transversal bars, welding joints) into simplified planar elements. This segmentation reduces the number of components and assembly operations required, thereby accelerating manufacturing while maintaining structural support functionality.
Solution Approach 2:
The invention merges the functions of multiple separate reinforcement bars (longitudinal and transversal) into integrated planar reinforcement elements. This consolidation eliminates the need for complex welding operations between multiple bars, simplifying the manufacturing process and increasing productivity.
3Force
If the surface of reinforcement is increased to improve effectiveness, then the admissible load increases, but the amount of reinforcement material increases
Solution Approach 1:
By transitioning from 3D bars to 2D plates, the invention achieves a dramatic increase in surface area within the same volumetric envelope. This allows the reinforcement to engage more effectively with the concrete matrix, increasing the admissible load without requiring proportionally more reinforcement material.
Solution Approach 2:
The invention optimizes the surface-area-to-volume ratio parameter by using planar geometry instead of cylindrical geometry. This parameter change enables achieving higher load-bearing capacity with reduced material quantity by maximizing the interface area between reinforcement and concrete.
