Aircraft Lamp Adjusting Irradiation Direction via Airframe Behavior Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft lamps with fixed irradiation directions struggle to adapt to the behavior of the airframe, leading to blurring and inadequate illumination of the operator's field of view, especially during changes in aircraft orientation and movement.
Innovation Solution
An aircraft lamp system featuring a variable lamp unit, behavior detection sensors (elevation angle, left-right tilt, and steering angle sensors), and a controller that adjusts the irradiation direction based on detected airframe behavior, ensuring constant illumination regardless of airframe orientation and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed irradiation direction lamp is used, then the device complexity is reduced, but the illumination appropriateness based on airframe behavior deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the lamp irradiation direction changeable based on airframe behavior. The lamp unit rotates around a rotation axis to change the irradiation direction dynamically, allowing the illumination to adapt to the airframe's movement and orientation, thus resolving the contradiction between simple structure and adaptive illumination.
2Device complexity
If the irradiation direction is switched only in two directions, then the device complexity is reduced, but the field of view coverage deteriorates
Solution Approach 1:
The patent enables continuous or multi-position rotation of the lamp unit around the rotation axis, allowing the irradiation direction to be adjusted dynamically to cover various fields of view required by the operator, rather than being limited to only two fixed directions.
3Manufacturing precision
If the irradiation direction is fixed, then the manufacturing precision requirements are reduced, but the illumination accuracy according to airframe direction deteriorates
Solution Approach 1:
The patent uses a rotation mechanism that allows the lamp to dynamically adjust its irradiation direction based on the airframe's behavior, eliminating the need for high manufacturing precision in fixed installation while maintaining accurate illumination direction through active control.
