Solution Overview

Problem

Conventional limb lining devices for catfish fishing are difficult to attach to bases such as dock cleats or boat supports, requiring time-consuming and potentially dangerous procedures, especially in low light conditions.

Innovation Solution

A limb line pole with an adapter assembly that includes a pole with a rigid and flexible section, allowing quick attachment to dock cleats or boat supports, and a flexible section to absorb fish pulling forces, preventing detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional limb lining methods are used where fishermen must take a boat up a river or on a lake to find suitable tree limbs and manually tie the limb lines, then the fishing setup can be completed, but the process is time-consuming and potentially dangerous especially in low light conditions

Engineering Contradiction:
Improveease of limb line setupVSAvoidtime required for setup
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent introduces an adapter assembly as an intermediary device that connects the pole to existing dock structures (cleats, posts, or other fixed points). This mediator eliminates the need for fishermen to manually search for and tie to tree limbs, allowing quick attachment from a dock instead of requiring a boat trip upstream or onto the lake.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a simplified copy or alternative version of the traditional limb line setup. Instead of replicating the complex process of finding tree limbs and tying lines manually, the adapter assembly provides a dock-based alternative that achieves the same fishing function through a much simpler attachment mechanism.

Inventive Principle:
Principle #26Copying

2Reliability

If conventional limb lining methods are used requiring manual attachment to tree limbs, then the fishing setup can be completed, but the process is potentially dangerous especially in the dark

Engineering Contradiction:
Improvesafety of setup procedureVSAvoiddifficulty of attachment procedure
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The adapter assembly serves as a safe intermediary that performs the attachment function in a controlled environment (dock) rather than requiring fishermen to work manually in potentially dangerous conditions (dark water, uneven tree limbs, boat instability). The mediator transfers the attachment task to a stable, accessible location.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the manual mechanical tying process with a simplified mechanical attachment system. The adapter assembly uses a straightforward connection mechanism that attaches to dock structures, eliminating the need for complex manual knot-tying procedures in difficult conditions.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Strength

If a rigid pole structure is used for limb lines, then the pole provides structural support, but it cannot absorb fish pulling forces which may cause detachment

Engineering Contradiction:
Improvestructural support of poleVSAvoidsecurity of attachment
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The patent applies different material properties to different parts of the pole structure. The proximal portion (near the adapter) is made of rigid material for structural support and stability, while the distal portion (near the fishing line attachment) is made of flexible material to absorb pulling forces from fish. This local differentiation of material quality allows each section to perform its specific function optimally.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The pole is constructed as a composite structure combining rigid and flexible materials in a single assembly. This composite construction allows the pole to simultaneously provide structural support (rigid portion) and shock absorption (flexible portion), preventing detachment while maintaining strength.

Inventive Principle:
Principle #40Composite materials
