Non-Standard Anchor Nuts for Utility Pole Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring systems for utility poles face challenges with non-conforming threaded anchor posts, leading to costly rework and removal of entire ground fixtures due to variations in thread diameters, which can be structurally sound but mismatch with standard anchor nuts.
Innovation Solution
A utility pole anchoring system that includes a set of anchor nuts with non-standard thread dimensions, along with a measuring device and chart to match the correct nut with the anchor post's dimensions, allowing secure anchoring without the need for expensive reinstallation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard anchor nuts are used with anchor posts that have thread variations, then manufacturing and installation are simplified, but the anchoring reliability deteriorates due to non-conforming thread dimensions
Solution Approach 1:
The patent applies parameter changes by providing anchor nuts with multiple thread parameters (different major diameters, minor diameters, and pitch values) to match anchor posts with varying thread dimensions. This allows the system to accommodate non-conforming threads while maintaining reliable anchoring, directly resolving the contradiction between reliability and adaptability.
2Reliability
If the entire ground fixture is removed and reinstalled to correct non-conforming anchor posts, then anchoring reliability is improved, but installation time and cost increase significantly
Solution Approach 1:
The patent extracts the problematic element (the non-conforming anchor post) from the system by replacing only the anchor nut component rather than the entire ground fixture. This selective replacement maintains anchoring reliability while avoiding the time-consuming process of removing and reinstalling the complete fixture.
Solution Approach 2:
The patent employs disposable anchor nuts as replaceable components that can be exchanged without affecting the permanent ground fixture. This approach uses a low-cost, easily replaceable component to solve the problem, avoiding the need for expensive and time-consuming reinstallation of the entire anchoring system.
3Reliability
If anchor posts are reworked to correct non-conforming threads, then anchoring reliability is improved, but the complexity and cost of repair increase
Solution Approach 1:
The patent extracts the repair problem from the anchor post by replacing only the anchor nut component. This avoids complex rework of the anchor post itself, significantly reducing repair complexity while maintaining anchoring reliability.
Solution Approach 2:
The patent uses replaceable anchor nuts as disposable components that can be easily exchanged without modifying the anchor post. This approach simplifies repair by using a low-cost, easily replaceable component rather than performing complex rework on the permanent anchor post structure.

AI summary
A utility pole anchoring system and associated methods are shown. In one example, a set of anchoring nuts is provided having at least one non-standard thread dimension. In one method of anchoring, a number anchor nuts from a set of non-standard thread dimensioned anchor nuts are selected to correspond to measured deviations in anchor thread dimensions.
