Arcuate Earth Drilling With Flexible Auger for Wiring Conduits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for burying wiring under obstacles like concrete sidewalks are labor-intensive, time-consuming, and disruptive to the landscape, often requiring demolition and dealing with weather-related challenges.
Innovation Solution
A power tool-driven arc-shaped pathway is used to bore a conduit for wiring, minimizing soil disturbance and eliminating the need for demolition by using an arced shaft, flexible drill extension, and auger bit to create a precise underground channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional excavation methods are used to create a pathway under sidewalks, then wiring can be installed, but labor intensity and time consumption increase significantly
Solution Approach 1:
The patent replaces traditional mechanical excavation tools (shovels, picks, drills) with a power-driven auger system that automatically bores through soil and concrete to create underground pathways. The auger bit, rotated by an electric or gas-powered drill, mechanically fractures and removes material much faster than manual tools, directly resolving the productivity-time contradiction.
Solution Approach 2:
The invention changes the operational parameters by using rotating auger bits with specific diameters and thread pitches optimized for different soil and concrete conditions. The power-driven system operates at controlled speeds and depths, allowing precise pathway creation without the time-consuming trial-and-error of manual excavation, thereby improving installation efficiency while reducing total project time.
2Productivity
If traditional excavation methods are used to install wiring under sidewalks, then wiring installation is achieved, but landscape disturbance and soil removal increase
Solution Approach 1:
The patent extracts only the minimal amount of soil and concrete necessary to create the wiring pathway by using a precisely controlled auger system. Unlike traditional excavation that removes large volumes of material, the auger bit drills a narrow cylindrical hole exactly where needed, leaving the surrounding landscape undisturbed and minimizing the substance that must be removed and later replaced.
Solution Approach 2:
The rotating auger bit creates a cylindrical (spheroidal cross-section) pathway rather than the irregular, wide-open cavities produced by manual excavation. This curved, compact geometry minimizes the volume of soil displaced and allows the auger to efficiently remove material through its rotating blades, reducing landscape disturbance while maintaining wiring installation productivity.
3Productivity
If traditional excavation methods are used, then wiring pathways can be created, but weather-related challenges and mud formation impede progress
Solution Approach 1:
The patent replaces manual excavation with a power-driven auger system that operates independently of weather conditions. The motorized drill provides consistent rotational force and depth control regardless of soil moisture or ambient temperature, allowing workers to maintain productivity in conditions where manual digging would be impeded by mud formation or physical exhaustion.
Solution Approach 2:
The auger bit's rotating blades automatically eject soil and debris from the pathway as they drill, eliminating the need for separate removal operations that would be hindered by muddy conditions. The system serves itself by continuously clearing its own pathway, maintaining installation efficiency even when soil becomes wet or sticky, whereas manual excavation would require additional labor and time to manage mud and debris.
