Crawler Robot Track Platform for Aircraft Fastener Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for drilling holes in aircraft structures are either manual and labor-intensive or use large, cumbersome automated systems that hinder movement and increase assembly time, as they require human operators to navigate difficult access areas.
Innovation Solution
A crawler robot system with a track system and multiple movement systems, including a pick and place arm and utility arm, that allows for precise positioning and operation on aircraft surfaces, enabling drilling, inspection, and fastener installation without the need for human operators in confined spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual drilling methods are used with human operators, then flexibility and accessibility to difficult areas are maintained, but the process becomes tedious, time-consuming, and labor-intensive
Solution Approach 1:
The crawler robot is equipped with onboard drilling equipment and autonomously navigates to difficult-to-access areas to perform drilling operations independently, eliminating the need for human operators to physically position themselves in confined spaces while maintaining operational flexibility
Solution Approach 2:
The patent replaces manual mechanical drilling operations with an automated crawler robot system that uses sensors for navigation and onboard motors for drilling, substituting human physical labor with automated mechanical and electrical systems
2Productivity
If large automated drilling systems are used, then productivity and automation are improved, but the systems become cumbersome and hinder movement within the assembly area
Solution Approach 1:
The patent divides the automated drilling function into a modular crawler robot platform that can independently navigate and position itself, separating the drilling capability from large fixed infrastructure and enabling movement throughout the assembly area
Solution Approach 2:
The crawler robot employs dynamic movement capabilities with adjustable speed and direction control, allowing it to adapt its motion to navigate around obstacles and access various drilling locations efficiently, combining automation with operational flexibility
3Manufacturing precision
If automated drilling systems are deployed, then drilling precision is improved, but the overall assembly process experiences delays due to system setup and repositioning
Solution Approach 1:
The crawler robot maintains continuous operation by autonomously navigating between drilling locations without requiring external repositioning or setup, keeping the drilling tool actively engaged in sequential operations across multiple fastener locations
Solution Approach 2:
The system uses sensors to detect fastener locations and provides real-time feedback for positioning the drilling tool, ensuring precise hole placement while minimizing positioning time through automated guidance and correction
