Captive Bolt Tool Two-Stage End Effector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current captive bolt tool systems for livestock euthanasia are either aesthetically displeasing due to penetrating methods or insufficient for humane dispatch in non-penetrating methods, as they typically only stun animals without ensuring irrecoverability.
Innovation Solution
A captive bolt tool system with interchangeable subject adapters and a two-stage end effector that allows for humane dispatch by cracking the skull without penetration, varying energy transfer based on adapter shape and operating distance, ensuring efficient kinetic energy transfer for instantaneous insensibility and irrecoverable trauma.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If penetrating captive bolt method is used, then euthanasia effectiveness is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The end effector is segmented into two distinct stages: a central element for skull cracking and a disk portion for energy transfer. This segmentation allows the first stage to achieve euthanasia effectiveness by cracking the skull without brain penetration, while the second stage handles energy transfer, thereby separating the functions to improve both effectiveness and aesthetics.
Solution Approach 2:
The central element of the end effector acts as an intermediary component that cracks the skull without penetrating the brain, serving as a mediator between the bolt and the brain tissue. This intermediary action achieves euthanasia effectiveness while preventing the aesthetically displeasing penetration into the brain.
2Shape
If non-penetrating captive bolt method is used, then aesthetic appearance is improved, but euthanasia effectiveness deteriorates
Solution Approach 1:
The end effector parameters are changed by varying the diameter and extension length of the central element relative to the disk portion. This allows optimization of the skull-cracking capability while maintaining non-penetration, thereby improving euthanasia effectiveness without compromising the aesthetic appearance of the non-penetrating method.
3Device complexity
If single-stage end effector is used, then device complexity is reduced, but energy transfer efficiency deteriorates
Solution Approach 1:
The end effector is divided into two functional stages: the central element for initial skull impact and cracking, and the disk portion for subsequent energy transfer. This segmentation optimizes energy transfer efficiency by ensuring efficient kinetic energy transfer from the bolt through the central element to the skull, and then through the disk portion, while maintaining a relatively simple overall structure.
4Device complexity
If fixed subject adapter is used, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The subject adapter is designed with a universal attachment mechanism that can be selectively removed and replaced with different adapters for different livestock species. This allows a single tool housing to serve multiple functions across different species, improving adaptability while maintaining relatively low device complexity through modular design.
