Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Recreational anglers face difficulties in retrieving heavy fish without breaking the fishing line or rod, as the fish can be too heavy to lift out of the water without risking line or rod damage.

Innovation Solution

A cylindrical fish retriever device made of high-density polyethylene, equipped with a longitudinal slit for the fishing line, additional lines for securing, and a flexible hook mechanism that allows the device to slide down the line and snag the fish, enabling safe retrieval without line or rod breakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the angler lifts the fish directly using the fishing line and rod, then the fish can be retrieved, but the fishing line or rod may break due to excessive weight

Engineering Contradiction:

Improvefishing line integrityVSAvoidfish weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The patent introduces a fish gripper as an intermediary device between the fishing line and the fish. The gripper attaches to the fish's mouth or body, allowing the angler to lift the fish without the full weight being transmitted to the fishing line and rod, thereby preventing breakage while enabling successful retrieval

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The lifting function is segmented into two parts: the fishing line controls the gripper's position and attachment, while the gripper bears the primary load of the fish. This segmentation allows the thin fishing line to control a much heavier object indirectly through the mechanical advantage provided by the gripper's design

Inventive Principle:

Principle #1Segmentation

2Strength

If the angler uses a heavy-duty line to lift heavy fish, then the line can support the weight, but the line may break the rod or cause other damage

Engineering Contradiction:

Improveline strengthVSAvoidrod damage risk

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The gripper serves as a mediator that distributes the load. Instead of the line directly supporting the entire fish weight, the gripper's structure (including buoyant elements and mechanical components) shares the load, allowing a lighter line to be used without risking rod damage

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If the angler releases the fish back into the water, then the fish can escape, but the fish may bite or injure the angler

Engineering Contradiction:

Improvefish releaseVSAvoidangler injury risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The gripper acts as a protective intermediary during fish release. The angler can detach the gripper from the fish while maintaining a safe distance, and the gripper's design allows for controlled release without requiring the angler to handle the fish directly, minimizing injury risk

Inventive Principle:

Principle #24Intermediary (Mediator)
