Segmented Bracket Exoskeleton for Corroded Pole Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Metal or wooden poles embedded in the ground often suffer from severe corrosion or decay at the groundline, making field repairs challenging due to weather conditions, depth limitations, and the need for skilled welders and time-consuming processes.
Innovation Solution
A clamping exoskeletal 'splint' device composed of fabricated brackets that are bolted together to provide a compressive force around the pole, offering a field-repair solution that can be installed by relatively unskilled labor, either by clamping or bolting directly to the pole, to reinforce and stabilize the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding reinforcing collars is used to repair corroded poles, then the pole strength is improved, but the repair complexity and time requirement increase
Solution Approach 1:
The reinforcing collar is divided into multiple segmental blocks that can be separately positioned and assembled around the pole. Each block contains integrated weldments that attach to the pole surface, allowing the repair to be broken into manageable sections rather than requiring a single complex welding operation
Solution Approach 2:
The repair solution transitions from a traditional axial reinforcing approach to a radial segmental configuration. The segmental blocks are arranged circumferentially around the pole, creating a three-dimensional distributed reinforcement structure that improves strength while simplifying the welding process by distributing welds across multiple smaller attachment points
2Strength
If welding reinforcing collars is used to repair corroded poles, then the pole strength is improved, but the time and expense involved increase
Solution Approach 1:
The reinforcing collar is divided into multiple segmental blocks that can be separately positioned and assembled around the pole. Each block contains integrated weldments that attach to the pole surface, allowing the repair to be broken into manageable sections rather than requiring a single complex welding operation
Solution Approach 2:
The weldments are pre-fabricated and integrated into the segmental blocks during manufacturing, rather than being applied in the field during repair. This preliminary preparation of welding components reduces on-site welding time and allows for quality control to be performed in a controlled manufacturing environment
3Strength
If welding reinforcing collars is used to repair corroded poles, then the pole strength is improved, but the availability of qualified welders becomes a limiting factor
Solution Approach 1:
The reinforcing collar is divided into multiple segmental blocks that can be separately positioned and assembled around the pole. Each block contains integrated weldments that attach to the pole surface, allowing the repair to be broken into manageable sections rather than requiring a single complex welding operation
Solution Approach 2:
The segmental blocks serve as intermediary components that bridge the pole surface and the reinforcing structure. These blocks with pre-integrated weldments act as modular units that simplify the welding process by providing standardized attachment points, making the repair task more accessible to welders with varying skill levels
4Strength
If welding reinforcing collars is used to repair corroded poles, then the pole strength is improved, but the depth below ground that reinforcement can be placed is limited
Solution Approach 1:
The reinforcing collar is divided into multiple segmental blocks that can be separately positioned and assembled around the pole. Each block contains integrated weldments that attach to the pole surface, allowing the repair to be broken into manageable sections rather than requiring a single complex welding operation
Solution Approach 2:
The repair solution transitions from a traditional axial reinforcing approach to a radial segmental configuration. The segmental blocks are arranged circumferentially around the pole, creating a three-dimensional distributed reinforcement structure that improves strength while simplifying the welding process by distributing welds across multiple smaller attachment points
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 solution effectively reinforces the pole by providing a compressive force that prevents further decay and corrosion, allowing for quick and effective field repairs without the need for specialized welding or skilled labor, thereby extending the pole's lifespan and maintaining structural integrity.
Implementation Method 1
the bolts being tightened to press the rear faces of the brackets against the surface of the pole and provide a clamping force against the pole to reinforce the pole

AI summary
A device and method for repairing a pole wherein pre-fabricated brackets are bolted together in the field to form a clamping ring, or exoskeletal splint around the pole, and wherein different sets of brackets can form different rings that are stacked and bolted together to clamp against and span enough of the height of the pole to provide the desired support.
