UV-Blocking Crop Coating Composition for Bird Damage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods to prevent bird damage to crops are inadequate, resulting in significant yield loss, as birds can easily detect and distinguish crops using ultraviolet wavelengths, leading to minimal effectiveness in existing bird repellent technologies.
Innovation Solution
A bird damage-preventing composition comprising an ultraviolet ray blocking agent made of zinc oxide, titanium dioxide, and a Thanaka tree extract, optionally with oxybenzone and avobenzone, is applied to crops or fruit protection bags to block ultraviolet rays, making fruits and seeds invisible to birds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional bird repellent methods (smell, visual effects, sounds) are used, then birds are repelled to some extent, but the effectiveness is minimal and 30% of crop yields are still damaged
Solution Approach 1:
The invention changes the parameter of light wavelength interaction by using UV-blocking agents that specifically block ultraviolet wavelengths (100-400nm) that birds can detect. This parameter change makes crops invisible to birds in the UV range while maintaining visibility for humans, directly addressing the limitation of conventional repellent methods
Solution Approach 2:
The invention uses composite UV-blocking materials including zinc oxide, titanium dioxide, and Thanaka tree extract applied to crops or fruit protection bags. This composite material approach creates a multi-layered protection system that effectively blocks UV rays, resolving the contradiction between repellent effectiveness and crop yield protection
2Loss of information
If crops are made visible in the ultraviolet range for human detection, then crops can be monitored, but birds can easily detect and distinguish them causing damage
Solution Approach 1:
The invention applies UV-blocking properties locally to crops or fruit protection bags, creating a selective visibility effect. Crops remain visible to humans in the visible spectrum while becoming invisible to birds in the UV range, thus protecting crops without compromising human monitoring capability
Solution Approach 2:
The invention effectively changes the 'color' or optical properties of crops in the UV spectrum by applying UV-blocking agents. This causes crops to appear invisible to birds detecting UV wavelengths while maintaining normal appearance for human observation, resolving the contradiction between monitoring and bird detection
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition effectively interrupts the birds' vision, reducing crop damage by making crops invisible in the ultraviolet range, thereby significantly decreasing yield loss.

AI summary
The present invention relates to a bird damage-preventing composition comprising an ultraviolet ray blocking agent comprising zinc oxide, titanium dioxide, and a Thanaka tree extract. The bird damage-preventing composition can interrupt the field of view of birds which recognize seeds and fruits, thereby reducing bird damage occurring at a crop cultivation site.
