Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bird abatement methods fail to provide lasting and consistent deterrence for birds to land and/or nest in unwanted areas, posing health risks and structural damage, and existing electromagnetic pulse systems are ineffective for various bird species and may lead to adaptation.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed frequency electromagnetic pulse (approximately 120 Hz) is used to deter pigeons, then pigeon deterrence is achieved, but other bird species may not be deterred and pigeons may eventually adapt to the frequency
Solution Approach 1:
The system dynamically adjusts the frequency of electromagnetic pulses based on detected bird species and behavior patterns. Rather than using a fixed 120 Hz frequency, the system varies frequency parameters in real-time to maintain effectiveness against different bird species and prevent adaptation, directly resolving the contradiction between versatility and lasting effectiveness.
Solution Approach 2:
The system changes multiple parameters including frequency, pulse width, and duty cycle to optimize deterrence for different bird species. By varying these parameters dynamically rather than using fixed values, the system achieves both versatility across species and sustained effectiveness by preventing birds from adapting to predictable patterns.
2Reliability
If electromagnetic pulse frequency and signal strength are increased to improve bird deterrence, then deterrence effectiveness improves, but regulatory compliance may be compromised
Solution Approach 1:
The system incorporates feedback mechanisms that monitor both bird behavior responses and environmental conditions. This feedback allows the system to adjust frequency and signal strength within regulatory limits while maintaining effective deterrence, resolving the contradiction between effectiveness and compliance by continuously optimizing parameters based on actual conditions rather than using fixed high-level settings.
Solution Approach 2:
The system dynamically adjusts electromagnetic pulse parameters including frequency and signal strength based on detected bird species, behavior patterns, and environmental conditions. This dynamic adjustment allows the system to maintain effective deterrence while staying within regulatory limits by using the minimum necessary signal strength at any given moment rather than continuously operating at maximum levels.
3Area of stationary object
If multiple emitters are spaced to cover large areas, then coverage area increases, but system complexity and cost increase
Solution Approach 1:
Each emitter in the system is designed as a universal unit capable of detecting multiple bird species and adjusting its output parameters independently. This multi-functionality allows fewer emitters to cover larger areas effectively, as each unit can adapt to different species and conditions rather than requiring specialized emitters for different zones, reducing overall system complexity.
