Line-Guided Fish Landing Net with Automatic Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing apparatuses, such as gaff hooks and traditional landing nets, are inadequate for efficiently and safely landing large game fish, often causing injury to the fish and limiting the effectiveness of 'Catch and Release' practices.
Innovation Solution
A line-guided fish landing net apparatus that securely attaches to a fishing line, featuring a guide rod with quick-connect clips, pivotally configurable arms, and pre-rolled net tubes that deploy into upper and lower net sections with flotation and weight assistance, allowing the net to automatically deploy and immobilize the fish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gaff hook is used to land large fish, then the fish can be securely landed on the vessel, but the fish suffers severe injury
Solution Approach 1:
The landing net is divided into multiple sections including a head section, body section, and hoop sections that can independently deploy and function. The net is segmented into panels that can flex and adapt to the fish's movement while maintaining capture effectiveness
Solution Approach 2:
The landing net serves as an intermediary tool between the fisherman and the fish, allowing secure handling without direct contact with the fish's body. The net panels and hoops act as a buffer that distributes force evenly, preventing concentrated pressure points that would cause injury
2Reliability
If a traditional landing net is used, then the fish can be landed, but the net is too small for large game fish
Solution Approach 1:
The landing net transitions from a compact stowed configuration to a fully deployed large configuration. The telescoping hoops and expandable body section allow the net to dynamically increase its surface area from a small portable form to a large game fish-sized net when needed
Solution Approach 2:
The landing net components are nested within each other in a compact form for portability. The hoops are telescoping and can be stored inside the body section, while the net panels are rolled or folded within the hoop structure, allowing a large net to be contained in a small package
3Reliability
If a landing net is deployed manually, then the fish can be captured, but manual intervention is required which slows the process
Solution Approach 1:
The landing net automatically deploys itself when attached to the fishing line and lowered into the water. The net sections self-assemble through water resistance and gravitational forces, with the hoops extending outward and the net panels unfurling without requiring manual operation
Solution Approach 2:
The landing net is pre-configured in a compact stowed state that automatically transitions to the deployed configuration upon contact with water. The quick-connect attachment mechanism is pre-positioned on the fishing line, ready to engage without requiring additional manual steps
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 apparatus effectively limits the mobility of large game fish, making it easier to land them on a fishing vessel while minimizing harm to the fish, and can automatically deploy and configure to capture the fish without manual intervention.
Implementation Method 1
The upper net sections are adapted with flotation devices and the lower net sections are adapted with weights to enable deployment thereof
Implementation Method 2
The upper net sections are adapted with flotation devices and the lower net sections are adapted with weights to enable deployment thereof

AI summary
A line guided fish landing net apparatus is affixed to a fishing line upon hooking a fish and placed in the water wherein nets are automatically deployed as the apparatus travels down the line. Once the net apparatus reaches the fish it wraps and entangles it thereby significantly diminishing its ability to thrash about making it much easier to land a large fish on a sport fishing vessel. An upper net section has a top peripheral edge thereof configured to be positively buoyant to spread to a deployed position, and a lower net section has a bottom peripheral edge configured to be negatively buoyant to spread to a deployed position.
