Anchor Bolt Adaptor for Misaligned Pole Foundations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Light pole installations often face misalignment issues between anchor bolts and base plate holes, leading to costly and time-consuming solutions like drilling out existing anchor bolts or demolishing and re-pouring foundations, due to the lack of adaptable systems that can accommodate misalignment without custom adaptors.
Innovation Solution
A coupling block with female threaded openings is positioned between anchor bolts and base plates, allowing for positional adjustment and secure anchoring without drilling, featuring a bolt extending from the block to pass through the base plate and secured with a nut, enabling alignment and adjustment of misaligned anchor bolts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional methods (drilling out existing anchor bolts or using custom adaptor plates) are used to correct misalignment, then the alignment between anchor bolts and base plate holes can be restored, but the cost and time requirements increase substantially
Solution Approach 1:
The patent introduces an intermediary component (adaptor plate with adjustable positioning features) that mediates between the misaligned anchor bolts and the base plate holes. This adaptor plate includes positioning blocks that can be adjusted to different locations to accommodate various misalignment scenarios, eliminating the need for time-consuming drilling and custom fabrication while restoring proper alignment.
Solution Approach 2:
The adaptor plate employs adjustable positioning blocks that can be moved to different positions and configurations to adapt to various misalignment parameters. This parameter adjustment capability allows the same adaptor plate to resolve different alignment issues without requiring custom fabrication for each specific case, thereby reducing time and cost.
2Manufacturing precision
If conventional methods (drilling out existing anchor bolts or using custom adaptor plates) are used to correct misalignment, then the alignment between anchor bolts and base plate holes can be restored, but the monetary cost increases substantially
Solution Approach 1:
The adaptor plate serves as a cost-effective intermediary solution that avoids the high costs associated with drilling out anchor bolts or fabricating custom adaptors. The standardized adaptor plate design with adjustable positioning features provides a economical way to restore alignment without requiring expensive custom manufacturing processes.
Solution Approach 2:
The adaptor plate is designed with universal applicability through its adjustable positioning blocks that can accommodate various misalignment scenarios. This multi-functional capability allows a single adaptor plate design to resolve multiple different alignment issues, reducing the need for multiple custom solutions and thereby lowering overall manufacturing costs.
3Strength
If anchor bolts are directly anchored into hard foundation materials, then strong anchoring is achieved, but misaligned anchor bolts require destruction of the anchor foundation to correct
Solution Approach 1:
The adaptor plate acts as a mediator between the anchor bolts and the base plate, allowing misalignment correction without requiring destruction of the anchor foundation. The positioning blocks on the adaptor plate can be adjusted to accommodate misaligned bolts while maintaining the integrity of the concrete foundation, thus preserving anchoring strength while improving ease of correction.
4Manufacturing precision
If custom adaptor plates are fabricated to correct misalignment, then precise alignment can be achieved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The adaptor plate is segmented into modular components, including adjustable positioning blocks that can be independently positioned and configured. This segmentation allows the adaptor plate to accommodate various misalignment scenarios without requiring a completely custom-designed complex adaptor for each case, thereby simplifying the overall device complexity while maintaining alignment precision.

AI summary
An anchor bolt adapter (ABA) for adapting a bolt circle of an anchor bolt foundation to a bolt circle of a pole is adapted to secure a base to a foundation. The ABA can comprise a downwardly positioned female threaded opening configured to receive a first one of the anchor bolts and an upwardly positioned female threaded opening configured to receive a threaded connector bolt.
