Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial structures, especially those with corrosive and hazardous materials, require frequent inspections that are laborious and costly, often necessitating manual operations and scaffolding, which are impractical and unsafe, especially for elevated or hard-to-access locations.
Innovation Solution
An unmanned aerial vehicle (UAV) equipped with a magnetic leg and a sensor activation device is used to autonomously attach to ferromagnetic surfaces, activate and read passive sensors installed on curved surfaces, such as pipes, allowing for efficient and safe inspection of multiple locations without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual inspection methods are used with handheld NDT probes, then inspection flexibility and accessibility are improved, but labor costs and time consumption increase significantly
Solution Approach 1:
The patent replaces manual mechanical inspection operations with an automated UAV system equipped with magnetic legs and NDT sensors. The UAV autonomously navigates to inspection locations, attaches to structures via magnetic legs, and performs measurements without human intervention, thereby maintaining accessibility while dramatically improving inspection efficiency and reducing labor costs
Solution Approach 2:
The inspection system performs self-service operations through autonomous UAV flight control, automatic target acquisition using cameras and GPS, self-attachment to structures via magnetic legs, and automated sensor deployment. This eliminates the need for manual operation while maintaining full inspection capability, resolving the contradiction between accessibility and efficiency
2Reliability
If permanent NDT sensors are installed at critical locations, then continuous monitoring capability is improved, but system cost and installation complexity increase
Solution Approach 1:
The patent transitions from static permanent sensor installations to a dynamic UAV-based inspection system. The UAV can be deployed periodically to perform inspections at multiple locations, providing continuous monitoring capability through repeated measurements without requiring permanent infrastructure at each sensor location, thereby reducing system complexity while maintaining reliability
Solution Approach 2:
The UAV system serves multiple inspection locations with a single platform, eliminating the need for separate permanent sensor installations at each critical point. The universal UAV can attach to various ferromagnetic structures, deploy different NDT sensors as needed, and collect data from multiple locations in one mission, reducing overall system complexity and cost
3Reliability
If scaffolding is erected to access elevated inspection areas, then inspection safety is improved, but setup time and operational cost increase
Solution Approach 1:
The patent replaces the mechanical scaffolding system with a UAV that flies directly to elevated inspection locations. The UAV uses magnetic legs to attach to ferromagnetic structures at height, eliminating the need for ground-based scaffolding infrastructure. This maintains inspector safety by removing human exposure to hazardous elevated work environments while eliminating time-consuming scaffolding erection and dismantling operations
Solution Approach 2:
The UAV acts as an intermediary between the inspector and the elevated inspection target. Instead of human inspectors physically accessing dangerous elevated areas via scaffolding, the UAV serves as a mediator that performs the inspection remotely, thereby ensuring safety without requiring time-intensive scaffolding setup
