Pivot Bracket Wall Support System for Bowed Foundation Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for supporting and straightening bowed or leaning foundation walls often apply eccentric loads to the floor structure, leading to inefficient load transfer and potential further deformation.
Innovation Solution
A support system utilizing a beam, pivot bracket, and plate that applies a direct compression load to the floor support structure, with the pivot bracket and plate working together to distribute the load evenly across the floor structure, preventing further bowing or leaning and potentially straightening the wall over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing support systems are used to support bowed walls, then the wall can be stabilized, but eccentric loads are applied to the floor structure causing inefficient load transfer and potential further deformation
Solution Approach 1:
The patent introduces a pivot bracket as an intermediary component between the support beam and the floor structure. This pivot bracket enables the application of compression force to the bowed wall while transferring the load through the beam to the floor structure in a more efficient manner, reducing eccentric loading and preventing further deformation
2Shape
If compression force is applied to straighten the bowed wall, then the wall can be straightened, but moment-induced stress is generated on the floor structure
Solution Approach 1:
Instead of applying force that creates moment-induced stress, the patent inverts the approach by using a pivot bracket system that applies compression force in a direction that minimizes moment creation. The pivot bracket allows the force to be applied more directly along the wall's axis, reducing the moment arm and consequently the moment-induced stress on the floor structure
3Device complexity
If a simple support system is used, then the device complexity is reduced, but the load distribution across the floor structure is uneven
Solution Approach 1:
The patent segments the support system into distinct components: a support beam and a pivot bracket. This segmentation allows the beam to provide structural support while the pivot bracket specifically manages the load transfer mechanism, enabling more even load distribution across the floor structure without requiring a completely complex system design
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively transfers a direct compression load to the floor structure, minimizing moment-induced stress and allowing for the stabilization and potential straightening of bowed or leaning walls by distributing the load efficiently, thereby preventing further deformation and allowing the wall to return to its original position as external forces recede.
