Goose Deterrent System Using 409 nm LED and Random Flashing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for deterring Canadian geese from specific areas, such as golf courses and airports, are ineffective due to habituation by geese and annoyance to humans, as they rely on predictable light and sound patterns that geese can adapt to, and often have unsightly industrial appearances that disrupt natural settings.
Innovation Solution
A system utilizing LED lighting with a wavelength of 409 nm, which is imperceptible to humans but visible to geese, combined with random flashing patterns and ultrasonic signals, is employed to deter geese without habituation, using aesthetically pleasing designs that integrate with natural environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional light and sound deterrent systems are used, then geese can be initially repelled, but geese quickly habituate to the predictable patterns and the systems become ineffective
Solution Approach 1:
The system dynamically changes light wavelengths, flash patterns, and sound frequencies in real-time based on environmental conditions and goose behavior responses. The controller adjusts parameters continuously to prevent geese from adapting to fixed patterns, transforming static deterrent signals into dynamic, adaptive signals that maintain effectiveness over time.
Solution Approach 2:
The system changes multiple parameters simultaneously including light wavelength (selecting from different LED colors), flash duration, flash intervals, sound frequency, and sound volume. By varying these parameters in combination and unpredictability, the system prevents geese from habituating to any single pattern while maintaining deterrent effectiveness.
2Reliability
If visible light is used to deter geese, then geese are repelled, but humans experience light annoyance and aesthetic disruption
Solution Approach 1:
The system uses different light wavelengths with specific local qualities - ultraviolet and blue wavelengths that are highly visible and disturbing to geese's visual system, but less visible to humans. This creates a localized effect where the light quality is optimized for goose repulsion while minimizing human annoyance in the same environment.
Solution Approach 2:
The system employs periodic flashing patterns rather than continuous light, with variable flash durations and intervals. This periodic action delivers deterrent signals to geese in pulses that are sufficient for repulsion while reducing overall light exposure to humans, thereby minimizing light annoyance and aesthetic disruption.
3Reliability
If industrial-style deterrent devices are deployed, then geese are deterred, but the devices have unsightly appearances that disrupt natural settings
Solution Approach 1:
The system uses realistic animal decoys (such as owl or hawk decoys) that copy the appearance of natural predators. These decoys are equipped with hidden light and sound emitters, allowing the deterrent function to be embedded within aesthetically pleasing, nature-integrated forms rather than industrial-style devices.
Solution Approach 2:
The system uses decorative elements such as flags, windsocks, or artistic sculptures as intermediaries that carry the deterrent technology. These intermediaries serve both aesthetic purposes and functional purposes, hiding the light and sound emitters within visually appealing structures that blend into natural settings.

AI summary
A system and method for driving geese away from an area employs predetermined random illuminations of particular wavelength light directed in a fashion that repels geese while avoiding annoying humans. Embodiments include systems associated with golf course pins and other structures and animal decoys that hide undesired aesthetic appearances of prior art industrial lighting elements. Other embodiments employ adjustable/movable mirror elements used in conjunction with systems powered by solar energy panels positioned below the light source, which can be adjusted in terms of direction, shielding, color, duration, wavelength and pulsation, providing a variety of random patterns so as to avoid habituation by geese.
