Snake Killing Tool With Movable Blade And Tines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snake-catching devices prioritize human safety over humane treatment, often resulting in the need to kill poisonous snakes immediately to prevent bites, rather than capturing them humanely.
Innovation Solution
A tool with a forked end and a movable blade on a pole, operated by an elastic band, compressible spring, or manually, designed to sever a snake's head once it is held, allowing for safe removal beyond the snake's striking range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a snake catching device is used to capture snakes humanely, then the humane treatment of snakes is improved, but the ability to quickly stop and kill poisonous snakes is worsened
Solution Approach 1:
The device merges two previously separate functions into one unified tool: the forked tines for capturing/holding the snake and the movable blade for decapitation. This combination allows the user to both humanely capture and quickly kill poisonous snakes with a single device, resolving the contradiction between humane treatment and reliable stopping capability.
Solution Approach 2:
The blade is designed to be movable rather than fixed, allowing it to transition from a retracted position (for safe transport and non-lethal capture) to an extended position (for immediate decapitation when needed). This dynamic feature enables the device to adapt between humane capture mode and rapid killing mode based on the situation.
2Device complexity
If the blade is made manually operable for simplicity, then the device complexity is reduced, but the speed and effectiveness of killing the snake is worsened
Solution Approach 1:
The elastic band creates a periodic action mechanism where the blade is automatically propelled forward with rapid speed when the trigger is activated, then returns to its retracted position. This periodic motion mechanism provides both the high speed needed for effective decapitation and the simplicity of manual operation, as the user only needs to pull the trigger rather than manually swing or thrust the blade.
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
Enables safe and humane killing of poisonous snakes by allowing the user to sever the head from a distance, prioritizing safety and effectiveness in snake control.
Implementation Method 1
The blade may be advantageously operated with an elastic band
Implementation Method 2
The blade may be hand-operated against the resistant force of a compressible spring

AI summary
A snake killing tool includes an outer body and a handle extending into the outer body. The handle retains a blade member at its bottom end. The outer body defines a pair of tines arranged to grasp a snake. The blade member is arranged for sliding movement within the bottom end of the outer body down to abutting contact with the tines. The blade member may be deployed mechanically or manually in a downward direction to sever the head of a snake.
