Foot Snare Triggering Device with Tandem Spring Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foot snare traps often result in 'toe catches' and lack efficient mechanisms for selective and humane capture of animals, with existing technologies relying on spring mechanisms that can be hazardous and inefficient in activating snares for various animal sizes.
Innovation Solution
A foot snare triggering device featuring a trigger plate assembly with adjustable pan tension, a tandem extension spring configuration, and a snare delivery system using wire springs to provide oblique movement, allowing for safer, more efficient, and selective snare deployment, with a detachable snare attachment port for releasing the snare after activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional spring mechanisms are used to activate the snare, then the trap can be triggered, but the risk of accidental triggering increases and safety during setup deteriorates
Solution Approach 1:
The triggering mechanism is divided into separate functional components: a trigger plate assembly with pan tension adjustment, a trigger mechanism with interlocking elements, and a snare delivery system. This segmentation allows each component to perform its specific function reliably while reducing the likelihood of accidental activation of the complete system.
Solution Approach 2:
The device incorporates preliminary safety features including a tensioned pan that must be deliberately depressed to initiate triggering, and interlocking trigger elements that prevent accidental release. The extension spring mechanism is pre-loaded in a controlled manner that requires intentional activation rather than random triggering.
2Ease of operation
If spring mechanisms are used to provide upward movement of the snare, then the snare can be activated, but the mechanism becomes hazardous and complex
Solution Approach 1:
Instead of using compression springs that push upward to activate the snare (conventional approach), this invention uses extension springs that pull in a controlled manner. The extension spring mechanism draws the trigger plate and snare assembly in a predetermined path, providing reliable activation while reducing mechanical complexity and hazard potential.
3Device complexity
If conventional triggers are located outside the spring mechanism housing, then the structure is simpler, but the trigger cannot be integrated with the extension mechanism
Solution Approach 1:
The trigger mechanism is merged with the extension spring housing, creating an integrated assembly where the trigger elements are positioned within the housing structure. This integration allows the trigger plate and spring mechanism to work together as a unified system, improving adaptability while maintaining structural coherence through the housing.
4Device complexity
If the snare is directly attached to the spring mechanism, then the structure is simpler, but the snare cannot be released after triggering
Solution Approach 1:
The snare attachment system transitions from a static direct connection to a dynamic releasable connection. The snare is attached to the trigger plate assembly through a mechanism that allows it to be secured during setup and then automatically released upon triggering, enabling the snare to be deployed and then detached for reuse.
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
The device minimizes non-target captures, reduces the risk of accidental triggering, and allows for precise capture of animals by providing a horizontal extension mechanism that pulls the snare upward and sideways, enhancing target specificity and safety during setup and use.
Implementation Method 1

AI summary
The foot snare triggering device of the present invention is designed to be used with a foot snare, and comprises a trigger plate assembly, having a tension adjustment means which allows the trigger plate assembly to pivotally yield to vertical pressure. A trigger mechanism has a trigger end set within said plate assembly and is attached to an extension mechanism providing a tandem extension spring configuration attached to a pair of pulleys, and a snare attachment port located within the trigger mechanism for releasably securing a foot snare by moving longitudinally when the trigger mechanism is engaged by pressure to said plate assembly allowing a foot snare to be released from the snare attachment port after triggering said device. A pan, pivotally connected to the plate underside distal to the pan tension adjustment means, has a trigger mount to engagingly receive the trigger mechanism.
