Collapsible Rigid Predator Image Display for Hiking Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing walking sticks that deter predators are either cumbersome, require excessive materials, or are ineffective in deterring charging predators, particularly due to limitations in size and balance when inflated.
Innovation Solution
A collapsible rigid structure within a hollow walking stick that deploys a large image of a fearsome creature, supported by a sharpened vertical rod and horizontal rods, allowing the stick to be used as both a deterrent and a defensive pike.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If inflatable devices are used to display predator images, then the device can be compact when stored, but it requires more material, is difficult to balance on a walking stick, and cannot effectively deter a charging predator once inflated
Solution Approach 1:
The patent removes the inflation mechanism and air-filled structure from the device, extracting the harmful aspect (excessive material, balancing difficulty) while retaining the core function of displaying a large predator image. The image is displayed on a rigid flat surface rather than an inflated structure.
Solution Approach 2:
The patent uses a two-dimensional printed image of a predator on a flat rigid panel as a copy or representation of a three-dimensional inflated structure. This copy achieves the same deterrent effect (displaying a large predator image) without requiring inflation materials or mechanisms.
2Volume of moving object
If inflatable devices are used to display predator images, then the device can be compact when stored, but it is difficult to balance on top of a walking stick
Solution Approach 1:
The patent extracts the inflation mechanism that causes balancing instability and replaces it with a rigid flat structure that provides stable balance on the walking stick while maintaining compact storage capability.
Solution Approach 2:
The patent uses a thin flat rigid panel to display the predator image, which is lightweight and easy to balance on the walking stick compared to a bulky inflated structure, while still providing a large visible image area.
3Volume of moving object
If inflatable devices are used to display predator images, then the device can be compact when stored, but once inflated it cannot be effectively used to deter a charging predator
Solution Approach 1:
The patent removes the inflation mechanism that limits effectiveness against charging predators and replaces it with a rigid structure that maintains structural integrity and deterrent effectiveness even during close encounters or charging events.
Solution Approach 2:
The patent incorporates a deployable mechanism that allows the device to transition from a compact stored state to an extended deployed state, enabling the user to quickly present the predator image when needed and maintain it in an effective position during predator encounters.
4Area of stationary object
If a large predator image is displayed, then the deterrent effect is enhanced, but the device becomes more cumbersome and harder to carry
Solution Approach 1:
The patent places the large predator image panel inside the hollow walking stick in a folded or nested configuration, allowing a large image area to be contained within a compact portable structure that is easy to carry during hiking.
Solution Approach 2:
The patent uses a deployable mechanism that allows the device to transition from a compact stored state to an extended deployed state, enabling the user to quickly present the large predator image when needed while maintaining portability during normal carrying.

AI summary
Disclosed herein is an apparatus for deterring predators, which may be used as a walking stick until a predator is encountered. Upon encountering a predator, the apparatus allows a user to rapidly deploy a collapsible rigid structure from the interior of the hollow walking stick, which supports a membrane, or set of membranes, that display the image of a fearsome creature. The deployed apparatus may also be used as an offensive or defensive pike should a predator charge a user of the apparatus. By increasing the apparent size of a user and displaying a large image of a fearsome creature, predatory animals may be deterred by this predator-intimidating walking stick.
