Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The safety of aircraft during night flights is compromised due to the challenges of maintaining visual sensor functionality in low-light environments, which can lead to reduced accuracy in flight control and increased risk of collisions or loss of aircraft visibility.
Innovation Solution
The implementation of a light supplementation lamp on aircraft equipped with a visual sensor, which emits light according to specific rules to provide a fill light function in the first flight state and an alerting function in the second flight state, ensuring the visual sensor's effectiveness and visibility of the aircraft in night or dark conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the light supplementation lamp provides fill light function for the visual sensor in night flight mode, then the visual sensor effectiveness is improved, but the aircraft visibility to others deteriorates
Solution Approach 1:
The patent applies dynamics by making the light supplementation lamp's emission characteristics adjustable based on flight state. The control method dynamically switches between fill light mode (for visual sensor effectiveness) and alerting mode (for aircraft visibility) according to real-time flight conditions, resolving the contradiction between these two opposing requirements.
Solution Approach 2:
The patent changes the parameters of light emission (intensity, duration, pattern) of the light supplementation lamp based on different flight states. By adjusting these parameters, the system optimizes performance for either visual sensor operation or aircraft visibility depending on the current flight conditions, thereby resolving the technical contradiction.
2Measurement precision
If the light supplementation lamp emits light continuously for fill light function, then the visual sensor effectiveness is maintained, but the energy consumption increases
Solution Approach 1:
The patent implements periodic action by controlling the light supplementation lamp to emit light in specific patterns rather than continuously. The alerting function uses periodic light emission with controlled duration and intervals, reducing overall energy consumption while still achieving the desired visibility effect. This periodic approach balances visual sensor effectiveness with energy conservation.
Solution Approach 2:
The system dynamically adjusts the light emission duration and intensity based on flight state. During critical flight phases, the lamp emits light longer and at higher intensity for visual sensor effectiveness. During stable phases, emission is reduced or periodic, lowering energy consumption while maintaining necessary performance.
3Object-affected harmful factors
If the light supplementation lamp implements alerting function with high intensity light emission, then the aircraft visibility is improved, but the visual sensor effectiveness deteriorates
Solution Approach 1:
The patent segments the light supplementation lamp's functionality into distinct modes: fill light mode for visual sensor effectiveness and alerting mode for aircraft visibility. By separating these functions into different operational states with different light emission characteristics, the system avoids the conflict between high-intensity alerting light and visual sensor performance. Each function is optimized independently through dedicated control rules.
