Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing airplane deicing vehicles suffer from slow operation actions, high misoperation probability, high labor intensity, slow boom retraction speed, and long boom retraction time due to manual control of the aerial operating arm, leading to reduced work efficiency and aircraft safety concerns.
Innovation Solution
A deicing vehicle with a one-key return function, equipped with sensors and a control system that automatically retraces the aerial operating arm to its initial position using a boom controller, folding arm angle sensor, first-section arm angle sensor, stay wire sensor, and rotary table angle encoder, allowing for precise and rapid retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control of the aerial operating arm is used, then the operator can control the boom movement, but the operation action is slow and the labor intensity is high
Solution Approach 1:
The system uses sensors to automatically detect the boom's position and control system to autonomously control the hydraulic cylinders, enabling the aerial operating arm to return to the initial position without manual intervention. This self-service mechanism reduces labor intensity while maintaining operational efficiency.
Solution Approach 2:
The patent replaces manual mechanical control with an automated control system that uses sensors to detect position and electronic control signals to operate the hydraulic cylinders. This substitution of mechanical manual operation with automated electromechanical control reduces labor intensity and improves operational speed.
2Reliability
If manual control of the aerial operating arm is used, then the operator can monitor the boom position, but the boom retraction speed is slow and retraction time is long
Solution Approach 1:
The system incorporates sensors that continuously detect the boom's position and feed this information back to the control system. The control system uses this feedback to automatically adjust the hydraulic cylinder operation, ensuring the boom returns to the initial position accurately and efficiently, reducing retraction time while maintaining reliability.
Solution Approach 2:
The control system is pre-programmed with the initial position coordinates of the boom. When retraction is needed, the system automatically executes the pre-planned return path, eliminating delays associated with manual monitoring and adjustment, thus reducing overall retraction time.
3Ease of operation
If manual control of the aerial operating arm is used, then the operator can control the boom movement, but the misoperation probability is high
Solution Approach 1:
The automated system performs self-control of the boom movement based on sensor feedback, eliminating human error and manual misoperation. The system independently determines the appropriate movement and execution, significantly reducing the probability of misoperation while maintaining ease of use through automatic functionality.
Solution Approach 2:
The sensor feedback mechanism continuously monitors the boom's actual position and compares it with the target position, automatically adjusting the control signals to the hydraulic cylinders. This closed-loop feedback system prevents misoperation by ensuring accurate positioning without manual intervention.
