UAV Arm Conductors for Adaptive Bird Repelling Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional unmanned aerial vehicles face challenges in reliably repelling birds and animals due to the variability in effective repelling frequencies and the potential for targets to become desensitized to the same frequency, leading to reduced effectiveness over time.
Innovation Solution
An unmanned aerial vehicle equipped with a main body, support arms, first and second electrical conductors, and a controller that applies different voltages to these conductors to create an electric shock, allowing for effective repulsion of targets by varying the electrical supply based on detected targets and environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound frequency is fixed to repel birds and animals, then the repelling effect is initially effective, but the target becomes accustomed to the frequency and the effect diminishes over time
Solution Approach 1:
The patent applies the dynamics principle by making the sound frequency variable rather than fixed. The control unit dynamically adjusts the frequency of the sound wave generated by the speaker based on detection results from the image recognition unit, ensuring the repelling sound remains effective as targets cannot adapt to constantly changing frequencies
Solution Approach 2:
The patent implements parameter changes by modifying the frequency parameter of the sound wave. The control unit changes the frequency parameter based on target detection and environmental conditions, allowing the system to maintain repelling effectiveness by preventing targets from becoming accustomed to a single frequency
2Reliability
If electric shock is applied to repel targets, then immediate repelling effect is achieved, but the complexity of the device increases due to additional electrical components
Solution Approach 1:
The patent applies the merging principle by combining the electric shock function with the existing support structure. The first and second electrical conductors are integrated onto the support arm, allowing the electric shock mechanism to be implemented without adding separate complex electrical structures, thus reducing overall device complexity while maintaining repelling effectiveness
