Wavelength-Specific Visual Cue Agents for Dichromatic Animal Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods are ineffective in repelling or attracting dichromatic animals, which are sensitive to only two wavelength regions, as they do not account for the animals' behavioral responsiveness to wavelengths outside their maximal sensitivity ranges.
Innovation Solution
The use of wavelength-specific visual cue agents combined with repellent or attractant agents, where the spectral characteristics of the visual cue agents are similar to those of the repellent or attractant agents but fall outside the dichromatic animals' maximal sensitivity ranges, to effectively repel or attract dichromatic animals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repellent or attractant agents are applied to targets, then behavioral response of dichromatic animals can be modified, but the effectiveness is limited because the agents' spectral characteristics fall within the animals' maximal sensitivity ranges
Solution Approach 1:
The patent applies parameter changes by shifting the spectral characteristics of visual cue agents from within the dichromatic animal's maximal sensitivity ranges to wavelengths outside these ranges (e.g., using UV wavelengths below 400nm when the animal's sensitivity peaks are at longer wavelengths). This parameter shift allows the visual cues to remain detectable while avoiding the animal's most sensitive detection zones, thereby improving repellent or attractant effectiveness without requiring the agents to operate within the animal's maximal sensitivity ranges.
2Reliability
If higher amounts of repellent or attractant agents are used to achieve effective repellency or attraction, then behavioral response decreases or increases by at least 5%, but the cost and environmental impact increase
Solution Approach 1:
The patent employs color changes by utilizing visual cue agents with spectral characteristics outside the dichromatic animal's maximal sensitivity ranges, effectively changing the 'color' or wavelength regime of the visual signals. By using wavelengths that are detectable but not maximally sensitive (such as UV wavelengths when the animal's cones peak at longer wavelengths), the system achieves effective behavioral modification with reduced agent quantities, as the animal's visual system processes these wavelengths differently, enhancing perception without requiring high concentrations.
3Device complexity
If repellent or attractant agents are applied alone, then the composition is simple, but the behavioral response modification is insufficient (less than 5% effectiveness)
Solution Approach 1:
The patent applies composite materials by combining repellent or attractant agents with visual cue agents that have complementary spectral characteristics. The visual cue agents are formulated with spectral properties outside the dichromatic animal's maximal sensitivity ranges, creating a composite composition where the visual cues enhance the effectiveness of the chemical agents. This composite approach achieves at least 5% behavioral response modification by synergistically combining the chemical repellent or attractant effects with enhanced visual perception cues.

AI summary
The combination of a repellent agent or an attractant agent with a wavelength-specific visual cue agent has been found to produce an unexpected and synergistic effect of increased repellency or attraction in dichromatic animals who are not maximally sensitive to the wavelength of the repellent or attractant agent. The method of the invention may be used to repel dichromatic-animal pests; or to prevent or minimize monetary damage, particularly to agricultural products, natural resources or private property. The method of the invention may also be used to attract dichromatic animals for the purpose of agricultural production, recreational opportunities (e.g., wild-rodent feeders), or the effective administration of target-animal pharmaceuticals or mitigation techniques.
