Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snake traps often unintentionally capture non-target species, pose risks to harmless animals, and can cause stress, dehydration, or injury due to lack of selectivity and safety, raising ecological and ethical concerns.
Innovation Solution
A hand-held snake snare with a motor-activated noose system that allows for selective capture by adjusting the loop size using a spindle and cable mechanism, providing a safe and humane method for capturing snakes or other animals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional snake traps are used, then snakes can be captured, but non-target species are unintentionally captured causing ecological imbalance
Solution Approach 1:
The noose loop is designed with specific size adjustments to match target snake dimensions, creating localized selectivity. The cable diameter and loop circumference are tailored to fit specific snake species while being too small for larger animals, ensuring the trap only affects the intended target.
Solution Approach 2:
The trap allows dynamic adjustment of the noose loop size by spooling or unspooling cable, changing the geometric parameters to match different target snake sizes. This parameter variability enables selective capture across different snake species while excluding non-target animals.
2Reliability
If traditional snake traps are used, then snakes can be captured, but trapped snakes suffer from dehydration, starvation, or stress
Solution Approach 1:
The rapid cinch mechanism instantly tightens the noose upon activation, immediately securing the snake without prolonged struggle. This preliminary swift action minimizes the time the animal spends in a distressed state before being securely contained.
Solution Approach 2:
The motor-driven spindle rapidly winds the cable to tighten the noose in seconds, rushing through the capture process quickly. This rapid action reduces the duration of stress and struggle, preventing dehydration and starvation that occur with traditional slow-acting traps.
3Reliability
If traditional snake traps are used, then snakes can be captured, but the traps pose dangers to pets and can cause injury or death
Solution Approach 1:
The noose loop size and cable diameter are specifically designed to match target snake dimensions, creating a localized fit that excludes larger animals like pets. The trap structure itself is designed to be safe for handlers while maintaining effectiveness against small snakes.
Solution Approach 2:
The adjustable noose loop allows dynamic sizing to match specific target snakes while being too small for larger animals. This dynamic adaptability ensures the trap remains effective for small snakes but becomes ineffective and harmless for larger pets.
4Reliability
If traditional snake traps are used, then snakes can be captured, but the traps lack selectivity and indiscriminately trap the wrong animal
Solution Approach 1:
The noose loop is designed with specific size parameters matching target snake dimensions, creating localized selectivity. The cable diameter and loop circumference are tailored to fit specific snake species while being too small for larger animals, ensuring the trap only affects the intended target.
Solution Approach 2:
The trap allows dynamic adjustment of the noose loop size by spooling or unspooling cable, changing the geometric parameters to match different target snake sizes. This parameter variability enables selective capture across different snake species while excluding non-target animals.
5Object-affected harmful factors
If a hand-held snare with motor-activated noose is used, then selective and humane capture is achieved, but the device complexity increases
Solution Approach 1:
The motorized spindle mechanism serves multiple functions: it winds the cable to tighten the noose, unwinds to release, and can be precisely controlled for selective capture. This multi-functional component reduces the need for separate mechanisms for different operations.
Solution Approach 2:
The manual mechanical advantage systems of traditional traps are replaced with a motorized spindle that provides controlled cable winding. This substitution simplifies the user interaction while maintaining the mechanical function, reducing complexity from the user perspective.

AI summary
A hand-held snake snare comprises an elongate hollow rod with a bracket mounted on a proximal end. The bracket mounts a spindle coupled to a motor for rotation of the spindle, which carries a length of cable. A power supply powers the motor to rotate the spindle and shorten or lengthen the unspooled portion of the cable. The rod mounts a block at the distal end and the cable passes through the hollow rod and out an aperture of the block. The free end of the cable is then attached at the block, such that a portion of the cable exiting the rod forms an adjustable loop. A switch connects the motor to the DC power supply, thereby turning the spindle to shorten the third portion of the cable forming the loop, such that an animal can be captured within the loop as a circumference of the loop is reduced.
