Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bird repellent methods, such as spicules, screens, and sticky gels, are ineffective or harmful, and existing electromagnetic devices only provide limited protection in specific areas, failing to address the widespread presence of birds like pigeons and gulls that pose health risks and cause property damage.
Innovation Solution
A bird repellent system using a pulse generator connected to a mesh of coils fixed to insulating plugs, generating an electromagnetic field that interacts with birds' magnetic orientation system, effectively repelling them from large areas by inducing a neurosensorial disturbance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional bird repellent methods (spicules, screens, sticky gels) are used, then birds are repelled from small areas, but these methods are ineffective against widespread bird presence and may harm birds or require frequent maintenance
Solution Approach 1:
The patent replaces mechanical bird repellent systems (spicules, screens, sticky gels) with an electromagnetic field-based system. The pulse generator creates electromagnetic pulses that interact with birds' magnetic orientation system, providing a non-mechanical solution that is more reliable and requires less maintenance.
Solution Approach 2:
The invention changes the operational parameters by using electromagnetic fields with specific frequencies (100-150 Hz) and voltages (1000-6000 V) that disrupt birds' magnetic navigation without causing physical harm. This parameter-based approach provides consistent effectiveness without the maintenance issues of mechanical systems.
2Area of stationary object
If electromagnetic devices are used to repel birds, then protection is provided against magnetic orientation, but the protection is limited to specific areas only
Solution Approach 1:
The patent divides the protected area into multiple zones, each covered by insulating plugs with coils at specific intervals (0.3-4 meters apart). This segmentation allows the system to cover large areas while maintaining consistent electromagnetic field strength throughout, ensuring reliable bird repellent effect across the entire protected zone.
Solution Approach 2:
The invention transitions from point-source electromagnetic devices to a distributed three-dimensional network of insulating plugs and coils. This spatial distribution creates a volumetric electromagnetic field that covers large areas consistently, rather than providing localized protection.
3Area of stationary object
If a mesh of coils is installed to cover large areas, then widespread bird protection is achieved, but the device complexity increases
Solution Approach 1:
The insulating plugs serve multiple functions: they provide electrical insulation, mechanical support for the wire coils, structural framework for the mesh, and mounting points for the system. This multi-functionality reduces overall device complexity while enabling large-area coverage.
Solution Approach 2:
The wire itself serves dual purposes: it provides the conductive path for electromagnetic current and simultaneously acts as the structural element forming the mesh. This self-service approach eliminates the need for separate structural and conductive components, simplifying the overall system.
