Multilayer Repellent Garment with Bite-Activated Capsicum Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deterrent devices for humans and animals against wild predators are either complex, expensive, or impractical for everyday use, failing to provide an effective and practical solution for repelling attacks by coyotes, bobcats, and other wildlife.
Innovation Solution
A multilayered composite textile product containing a non-lethal repellent substance, such as Capsicum oleoresin, is embedded within a core carrier substrate that releases only when bitten by a predator, utilizing microencapsulation and protective layers to ensure safe and effective deterrence without harming the wearer or animal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior art repellent devices are used, then some level of predator deterrence is achieved, but the devices are complicated, expensive, or not practical for everyday use
Solution Approach 1:
The repellent device is segmented into multiple functional layers: a protective outer layer that resists normal wear and tear, a core carrier substrate layer containing the repellent substance, and a reactive layer that releases the repellent when activated by predator bite pressure. This segmentation allows each layer to perform its specific function independently, simplifying the overall device while maintaining effectiveness
Solution Approach 2:
The device uses a disposable, single-use design where the repellent is released upon activation and the device is discarded afterward. This eliminates the need for complex reloading mechanisms or electronic components, making the device simple, inexpensive, and practical for everyday use while maintaining high reliability in predator deterrence
2Reliability
If the repellent substance is released continuously, then predator deterrence is maintained, but harm to humans or animals may occur
Solution Approach 1:
The device incorporates a protective outer layer and a core carrier substrate that prevent the repellent substance from being released under normal conditions. The repellent is held in reserve and only released when a predator applies sufficient bite pressure, thereby preventing harm to humans or animals while maintaining effectiveness against predators
Solution Approach 2:
The device changes the release parameter of the repellent from continuous or constant pressure to pressure-threshold activation. The repellent is released only when the applied pressure exceeds a specific threshold (predator bite pressure), which distinguishes between normal wear and actual predator attacks, thereby preventing harm while maintaining deterrence effectiveness
3Strength
If the protective layers are made highly puncture resistant, then protection against predators is improved, but normal activities may be restricted
Solution Approach 1:
The protective outer layer is designed with local quality variations where different areas have different thicknesses or material properties. Areas requiring higher protection (such as vital body regions) have enhanced puncture resistance, while other areas are more flexible to allow normal movement and comfort during everyday activities
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 device effectively repels predators by releasing a non-toxic, non-lethal repellent upon bite, providing sufficient time for escape or rescue while being durable and resistant to normal activities, with a total puncture resistance of over 200 psi, ensuring protection without harming humans or animals.
Implementation Method 1
the non-toxic, non-lethal repellent substance may be provided and applied to be absorbed or drawn into the core carrier substrate through one or both planar surface (and/or ends) of the core carrier substrate
Implementation Method 2
The repellent substance (encapsulated or non-encapsulated) may be applied directly onto one or both planar surfaces of the core carrier substrate (adsorption)
Implementation Method 3
The repellent substance is enclosed in a plurality of microcapsules, wherein each of the plurality of microcapsules are configured for containing the non-toxic, non-lethal repellent substance... released only when device/garment bitten by predator

AI summary
A multilayer protective device such as, but not limited to, a garment such as a vest or arm or leg wrap, a bag, a backpack, wraps for tents, camping items, etc. designed to be worn by domesticated or farm animals of various sizes and/or humans or placed on objects for which predator attack is to be deterred. The multilayer protective device is made from a multi-layered composite textile containing a non-toxic, non-lethal repellent substance such that upon a bite from an attacking animal, the non-toxic, non-lethal repellent substance is released deterring the attacking animal for such a time as to allow the wearer or user of the protective device to escape or be rescued.
