Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for dispensing fluids on airplane surfaces require skilled operators, are time-consuming, and prone to inefficiencies such as missed areas, excess fluid use, and prolonged ground time due to operator-dependent decision-making.
Innovation Solution
An autonomous method and system using sensors and a processing unit to create a 3D representation of the airplane surface, determining optimal dispensing points and paths for fluid application, allowing for autonomous fluid dispensing without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If skilled operators manually control the dispensing system, then the fluid application can be adjusted based on visibility and judgment, but the process is time-consuming and requires extensive training
Solution Approach 1:
The system enables autonomous operation where the dispensing system performs fluid application without human intervention. Sensors detect the airplane surface and automatically control nozzle movement and fluid dispensing, eliminating the need for skilled operators while maintaining application quality through automated feedback control
Solution Approach 2:
Manual mechanical control by operators is replaced with an automated system combining sensors, processors, and controlled dispensing mechanisms. The system uses sensor data to automatically determine optimal paths and fluid application rates, substituting human judgment with automated decision-making algorithms
2Ease of operation
If operators manually navigate the dispensing system, then they can make real-time decisions, but mistakes lead to missed areas and excess fluid use
Solution Approach 1:
The system incorporates sensors that continuously monitor the dispensing process and provide feedback to the control system. This real-time feedback enables automatic adjustment of nozzle position and fluid flow rate, ensuring precise fluid application without operator error while eliminating the need for skilled manual operation
Solution Approach 2:
An automated control system acts as an intermediary between sensor detection and fluid dispensing. This intermediary process automatically calculates optimal paths and controls execution, removing human error from the process while maintaining ease of operation through simple automated control
3Reliability
If operators take thorough paths to ensure complete coverage, then all surfaces are treated, but the process takes longer
Solution Approach 1:
The system performs preliminary detection of the airplane surface geometry and pre-calculates optimal dispensing paths before fluid application begins. This preliminary action allows the system to plan efficient routes that ensure complete surface coverage while minimizing travel time, achieving both reliability and productivity

AI summary
A method for applying a fluid, such as deicing fluid, to a surface of an airplane. A vehicle loaded with a fluid has a nozzle for spraying said fluid onto said surface and at least one sensor and a processing unit is provided for determining a 3D representation of the surface onto which fluid is to be added. The 3D representation is used to determine boundary conditions for a path along which the nozzle is moved relative to the surface and the fluid is being dispensed onto the surface as said nozzle is being moved along the path.
