Wireless Telemeter Tool for Landing Gear Maneuvering Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adjusting the maneuvering mechanism of a retractable main landing gear of an aircraft to ensure sufficient space between the doors and the gear for safe closure is challenging, requiring manual measurement and adjustment within the landing gear bay, which is unsafe and inefficient.
Innovation Solution
A tool with a telemeter and wireless communication unit allows remote adjustment of the maneuvering mechanism by locking onto a wheel, enabling measurement and display of the distance without an operator needing to be inside the bay, using a telemeter connected to a control device for precise adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an operator positions themselves in the landing gear bay to manually measure the distance, then measurement can be performed, but operator safety is compromised and the process is inefficient
Solution Approach 1:
The patent introduces a telemeter as an intermediary device to perform distance measurements between the landing gear and the bay door without requiring an operator to physically position themselves in the landing gear bay. The telemeter is mounted on the landing gear and measures the distance to the bay door, transmitting the data wirelessly to eliminate safety risks while maintaining measurement precision
Solution Approach 2:
The patent replaces the manual mechanical measurement process with an optical/electronic telemeter system. Instead of an operator using physical tools to measure distance, the telemeter uses light or electromagnetic waves to measure and transmit distance data wirelessly, eliminating the need for manual intervention in the landing gear bay
2Manufacturing precision
If manual measurement and adjustment is performed within the landing gear bay, then adjustment can be made, but the process is time-consuming and inefficient
Solution Approach 1:
The patent implements a feedback system where the telemeter continuously measures the distance between the landing gear and the bay door, and this data is transmitted wirelessly to operators or control systems. This real-time feedback enables precise adjustment of the maneuvering mechanism without requiring repeated manual measurements, significantly improving adjustment efficiency while maintaining precision
Solution Approach 2:
The telemeter system enables the landing gear system to self-measure and provide distance data without requiring external manual intervention. The automatic measurement and wireless transmission of data reduces the time and labor required for adjustment operations while maintaining precise control over the retraction clearance
