Autonomous Manhole Cover Removal for Roadway Utility Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual inspection and maintenance of manholes are time-consuming and expose workers to unsafe conditions, as they require human intervention to remove and replace covers, which can be hazardous and inefficient.
Innovation Solution
A self-driving vehicle equipped with a manhole cover handling mechanism and tool handling mechanism that can automatically find, remove, and replace manhole covers, allowing for automated inspection and maintenance without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual inspection and maintenance of manholes is performed, then workers can directly access and inspect the underground utility, but workers are exposed to unsafe conditions and the process is time-consuming
Solution Approach 1:
The automated vehicle performs manhole inspection and maintenance tasks independently without human intervention. The vehicle autonomously navigates to manholes, removes covers using the cover removal device, deploys inspection tools, collects data, and replaces covers, thereby eliminating worker exposure to hazardous conditions while maintaining operational efficiency
Solution Approach 2:
The patent replaces manual mechanical operations with an automated vehicle system equipped with specialized devices. The cover removal device, tool deployment mechanisms, and data collection systems are all mechanically automated, substituting human physical labor and exposure with machine-based operations that improve both safety and efficiency
2Productivity
If manual manhole cover removal and replacement is performed, then inspection and maintenance can be conducted, but the process requires significant human intervention and time
Solution Approach 1:
The patent combines multiple functions into a single integrated automated vehicle system. The vehicle merges cover removal, tool deployment, inspection data collection, and cover replacement operations into one autonomous platform, eliminating the need for separate manual operations and significantly reducing total inspection time
Solution Approach 2:
The automated vehicle is pre-equipped with all necessary tools and devices before reaching the manhole. The cover removal device, inspection tools, and replacement mechanisms are prepared in advance on the vehicle, allowing immediate execution of the inspection sequence without delays for tool retrieval or manual preparation
Data Source
AI summary
The use of a self-driving vehicle to automatically find manholes, and for each remove the manhole cover from the manhole, and thereafter put the manhole cover back in position on the manhole. In some embodiments, while the manhole cover is removed, the self-driving vehicle is used to automatically place a tool above or within the manhole. Accordingly, a self-driving vehicle can automatically inspect, repair, or maintain manholes that are positioned in roadways. The data can then automatically be gathered without human intervention.
