Multi-Layer Snare Barrier with Variable Netting Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current barriers fail to effectively deter and capture snakes and rodents of varying sizes while minimizing visual impact on the surroundings.
Innovation Solution
A land animal snare barrier system comprising multiple layers of netting with varying hole sizes, attached to vertical and ground supports, designed to entangle and trap snakes and rodents, with optional translucent material for low visibility and integrated sensors for alerting mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single layer of netting with uniform hole size is used, then the barrier structure is simple, but it cannot effectively trap snakes and rodents of varying sizes
Solution Approach 1:
The netting barrier is segmented into multiple layers, each with different hole sizes. The first layer has larger holes (e.g., 1 inch) to accommodate larger snakes, while subsequent layers have progressively smaller holes (e.g., 3/4 inch, 1/2 inch, 1/4 inch) to trap smaller snakes and rodents. This segmentation allows the barrier to effectively capture animals of varying sizes without requiring a completely different barrier for each animal type.
Solution Approach 2:
Different regions of the netting barrier have different hole sizes tailored to specific functions. The first layer with larger holes is positioned to intercept larger animals, while inner layers with smaller holes are positioned to trap smaller animals that pass through the outer layers. This local differentiation of hole sizes optimizes the trapping effectiveness for each animal size category.
2Object-affected harmful factors
If opaque barrier material is used, then the barrier is highly visible and easily detected, but it has significant visual impact on the surroundings
Solution Approach 1:
The netting material is made translucent rather than opaque, allowing it to blend with the surrounding environment. The translucent quality reduces visual impact by permitting light transmission and background visibility, making the barrier less obtrusive while maintaining structural integrity and detection capability through tactile and visual cues.
3Adaptability or versatility
If larger hole sizes are used in netting, then larger animals can pass through, but smaller animals cannot be effectively trapped
Solution Approach 1:
The barrier is divided into multiple netting layers with progressively smaller hole sizes. The first layer has larger holes to allow smaller animals to pass through to inner layers, while the cumulative effect of multiple layers with decreasing hole sizes ensures that animals of all sizes are eventually trapped. This segmented approach solves the problem of selecting appropriate hole sizes for different animal dimensions.
4Adaptability or versatility
If multiple layers of netting with different hole sizes are used, then snakes and rodents of all sizes can be trapped, but the device complexity increases
Solution Approach 1:
Multiple netting layers with different hole sizes are merged into a single integrated barrier system. The layers are positioned sequentially with the first layer having larger holes and subsequent layers having smaller holes, creating a unified structure that traps animals of all sizes. This merging approach consolidates what would otherwise require multiple separate barriers into one cohesive system.
