Reinforced Structural Member Fabrication With Nonuniform Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reinforced concrete structures are over-engineered to compensate for inefficient placement of reinforcing elements, which results in wasteful use of materials and labor, as they are designed to resist lateral loads from two opposing directions, leading to half the material being structurally non-functional.
Innovation Solution
A modular framework system that allows for precise placement of reinforcing elements, including recessed regions and optimized positioning of reinforcing elements to enhance resistance to bending moments, minimizing material usage while maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reinforcing elements are placed at the midpoint of the wall to resist lateral loads from two directions, then the structure can withstand loads from both directions, but half the material becomes structurally non-functional and material usage increases
Solution Approach 1:
The patent applies local quality by varying the reinforcement configuration in different regions of the wall. Instead of uniform midpoint placement, the system uses asymmetric reinforcement layouts that concentrate steel where lateral loads are most critical, allowing different zones to have optimized reinforcement patterns rather than a one-size-fits-all approach
Solution Approach 2:
The patent implements asymmetry by designing reinforcement patterns that are not symmetric about the wall centerline. The system positions reinforcing elements at non-uniform intervals and with varying orientations to match the asymmetric nature of lateral load distributions, eliminating the waste caused by symmetric midpoint placement that over-reinforces certain areas
2Strength
If more concrete is used to support vertical loads, then the structure can bear greater weight, but the construction becomes less efficient and more materials are wasted
Solution Approach 1:
The patent applies preliminary action by incorporating vertical reinforcement elements during the formwork assembly stage, before concrete pouring. The system pre-positions steel bars and meshes within the formwork structure, ensuring proper placement and integration with lateral reinforcement, which eliminates the need for excessive concrete to compensate for potential reinforcement placement errors
3Reliability
If reinforcing elements are positioned to provide sufficient resistance to lateral loads, then the structure meets safety requirements, but optimal resistance and material efficiency are not achieved
Solution Approach 1:
The patent applies segmentation by dividing the wall into multiple zones with different reinforcement requirements. The system segments the reinforcement into vertical bars, horizontal bars, and mesh components that can be independently positioned and optimized for specific load conditions, allowing precise material placement rather than uniform reinforcement throughout
Solution Approach 2:
The patent implements parameter changes by varying reinforcement density, bar diameter, spacing, and orientation based on local structural demands. The system adjusts these parameters across different wall regions to match anticipated load patterns, achieving optimal resistance with minimized material usage rather than using fixed reinforcement specifications

AI summary
A structural member optimized to resist lateral forces, as well as systems and methods of fabricating and implementing same, are disclosed. In some implementations, a modular framework erected at a work site may support forms used for the fabrication of reinforced concrete or masonry structural members which do not have uniform cross-sectional thickness. The modular nature of the framework allows a construction crew to arrange the forms quickly and precisely on site, and the varying cross-sectional thickness of the structural member and positioning of reinforcing elements economize on materials usage while simultaneously increasing the structural member's resistance to lateral loading.
