Crossbow Aquatic Retrieval Device with Spool Line Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aquatic animal retrieval devices, particularly those used with crossbows, face challenges such as line entanglement, difficulty in locating and retrieving aquatic animals like alligators, and require significant strength, making them inconvenient and sometimes ineffective.
Innovation Solution
An aquatic animal retrieval device with an L-shaped mount and V-shaped spool system that attaches to a crossbow, featuring a float with a hook and loop mechanism to prevent line entanglement and ensure secure attachment of a float to the arrow, allowing for easy retrieval without undue drag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an archery bow is used for aquatic animal retrieval, then the device can be operated with less strength requirement, but line entanglement with bowstring occurs and maneuvering space is reduced
Solution Approach 1:
The patent extracts the line management system from the traditional archery bow setup by introducing a separate spool device that winds and stores the retrieval line. This separates the line handling function from the bowstring, eliminating line entanglement issues while maintaining the ease of operation benefit.
Solution Approach 2:
The spool acts as an intermediary device between the user and the aquatic animal. It mediates the line transmission, providing controlled payout and retrieval while preventing direct entanglement between the line and bowstring. The spool serves as a buffer that manages line tension and direction.
2Speed
If a crossbow is used for aquatic animal retrieval, then sufficient arrow shaft velocity is achieved, but line entanglement with crossbow components occurs
Solution Approach 1:
The patent removes the line management function from the crossbow system by introducing an independent spool device. This extraction prevents the line from entangling with crossbow components while maintaining the high velocity advantage of crossbows for successful animal retrieval.
3Reliability
If gaffs and spears are used for alligator retrieval, then the animal can be secured, but significant strength is required and game loss is common
Solution Approach 1:
The patent replaces the manual mechanical system of gaffs and spears with a powered retrieval system using a spool and line. The crossbow provides the mechanical force needed to retrieve heavy alligators without requiring the user to exert significant strength, while the line-and-spool system provides more reliable and controlled retrieval than manual tools.
