Low-Profile Snake Barrier Using L-Shaped Modular Screen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snake barriers are ineffective in preventing venomous and non-venomous snakes from entering protected areas, as they often rely on visual deterrents that are ineffective for snakes with poor vision and rely on smell and heat sensors for navigation.
Innovation Solution
A lightweight, portable snake barrier system comprising vertical and lateral components that prevent snakes from crawling over by using a flexible screen mesh supported by corner and intermediate braces, which can be easily assembled and disassembled to form a perimeter around areas such as campsites, homes, and public spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual deterrents are used to prevent snakes from entering protected areas, then the barrier can be simple in structure, but it is ineffective because snakes have poor vision and rely on smell and heat sensors
Solution Approach 1:
The patent transitions from two-dimensional visual deterrents (fences, walls) to three-dimensional physical barriers that engage snake anatomy. The L-shaped configuration with vertical and horizontal components creates a dimensional obstacle that physically blocks snakes based on their crawling morphology, rendering their sensory systems irrelevant to barrier effectiveness.
Solution Approach 2:
The barrier is divided into modular L-shaped sections that can be independently assembled. Each segment contains both vertical and horizontal components forming a complete deterrent unit, allowing the system to be scaled and configured for different protected areas while maintaining consistent snake-blocking functionality.
2Reliability
If traditional snake barriers are designed to be effective, then they provide reliable protection, but they are difficult to assemble and transport
Solution Approach 1:
The barrier system is segmented into standardized L-shaped modules that can be easily transported individually and assembled through simple connection mechanisms. This modular approach maintains effective snake deterrent geometry while dramatically improving portability and assembly ease compared to traditional monolithic barrier designs.
Solution Approach 2:
The barrier incorporates flexible or adjustable components that allow the structure to be dynamically assembled and disassembled. The L-shaped sections can be configured, reconfigured, or collapsed for transport, providing both operational effectiveness and logistical flexibility.
3Reliability
If the barrier height is increased to prevent snakes from crawling over, then snake protection is improved, but the barrier becomes more prominent and less aesthetically pleasing
Solution Approach 1:
Instead of increasing barrier height in one dimension, the patent uses L-shaped sections that extend in multiple dimensions. The vertical component prevents over-crawling while the horizontal component creates an outward overhang that blocks access, achieving effective snake prevention with a lower overall profile than traditional vertical walls.
Solution Approach 2:
The L-shaped configuration creates angled surfaces that redirect snake movement rather than presenting a sheer vertical wall. This geometric approach prevents snakes from gaining purchase to climb over while maintaining a lower, less obtrusive profile compared to straight vertical barriers.

AI summary
A low-profile snake barrier includes a plurality of sections that form a boundary. One section of the plurality of sections includes a screen-type material that is supported by a first support brace at a first end of the one section and a second support brace at a second end of the one section opposite the first end. The support braces support the screen-type material in a collapsed configuration and an erect configuration, where the erect configuration includes an upright portion of the screen-type material extending upward from the ground and an overhang portion of the screen-type material extending from the upright portion. In the collapsed configuration, the upright portion and the overhang portion are parallel to the ground. Each support brace include pivotably coupled members.
