Portable Longline Deployer Guide Channel for Small Boat Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing longline deployers are too large for use on small boats, requiring manual deployment and posing risks of hooks catching on the boat or body parts, limiting their use due to stability and space constraints.
Innovation Solution
A portable longline deployer with a housing and guide channel that allows the fishing gear to be guided over the gunwale, featuring a coupling flange for secure attachment to various container shapes and sizes, and a locking mechanism for easy movement and adaptation, enabling deployment from a seated position without risking hooks catching on the boat or body parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a prior-art longline deployer is used, then the longline can be deployed safely without hooks catching on the boat or body parts, but the deployer is too large for use on small boats and requires the boat to be stable enough for a person to stand upright
Solution Approach 1:
The longline deployer is divided into separate modular components: a deployer unit and a container. The deployer unit can be detached and reattached to different containers (buckets, tubs, barrels) depending on the boat size and fishing needs. This segmentation allows the same deployer mechanism to be used on both small and large boats, resolving the contradiction between safety and size.
Solution Approach 2:
The deployer unit is designed to be movable rather than fixed, allowing it to be transferred between different boats and storage locations. The coupling flange with locking mechanism enables easy attachment and detachment, making the system adaptable to different boat sizes and stability conditions without compromising deployment safety.
2Productivity
If a prior-art longline deployer is permanently installed on a boat, then deployment is efficient and safe, but space is occupied on the boat and the installation/dismantling process is time-consuming
Solution Approach 1:
The deployer unit is designed as a movable, detachable component rather than a permanent installation. It can be quickly coupled to and decoupled from different containers using the flange and locking mechanism, allowing boat owners to install it only when needed for longline fishing while freeing up space for other uses when not in use.
Solution Approach 2:
The deployer unit can be used with multiple types of containers (buckets, tubs, barrels) and can be transferred between different boats, making it a versatile tool that serves multiple fishing scenarios without requiring permanent installation on any single boat, thus maximizing space flexibility.
3Adaptability or versatility
If manual deployment is used on small boats, then space and stability constraints are avoided, but there is a risk of hooks catching on the boat or body parts
Solution Approach 1:
The guide channel acts as an intermediary structure that directs the longline and hooks through a controlled path from the container over the gunwale and into the water. This intermediary guide prevents hooks from randomly contacting the boat structure or the fisher's body, eliminating the safety risks of manual deployment while remaining compatible with small boat constraints.
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 efficient deployment of longlines from small boats with limited space and stability, simplifying the process and reducing the risk of injury, while allowing easy transfer between boats and vehicles.
Implementation Method 1
The gravity of the weight at the first end portion of the longline and the propulsion of the boat pull the longline out of the longline tub and through the longline deployer
