Solution Overview

Problem

Traditional fishing rigs face issues such as snagging, twisting, and limited adjustability in harsh conditions, especially when targeting multiple species and using varied fishing methods, due to the design limitations of sinker and inline float combinations.

Innovation Solution

A fishing rig design that includes a main leader with an inline float and a side leader assembly, utilizing specific knots and beads to allow for adjustable tension and height, enabling better stability and versatility in different fishing environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a free-floating cylinder float is used on the main line or side leader, then the rig can be easily assembled, but the float and leader twist in current and the sinker will snag

Engineering Contradiction:
Improveease of assemblyVSAvoidfloat integrity
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent applies the dynamics principle by making the inline float adjustable in both tension and height. The float can slide along the main leader to different positions and tensions can be adjusted by moving the stop bead, allowing the rig to adapt to varying current conditions and fishing scenarios, preventing twisting and snagging while maintaining ease of assembly

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by allowing the float position (height parameter) and tension (slip parameter) to be variable rather than fixed. The stop bead can be repositioned to change the float's vertical position, and the tension can be adjusted by moving the stop bead along the main leader, enabling optimization of rig performance for different fishing conditions

Inventive Principle:
Principle #35Parameter changes

2Strength

If tighter knots are used to increase slip tension, then the leader attachment is more secure, but memory or abrasion issues occur

Engineering Contradiction:
Improveslip tensionVSAvoidmemory and abrasion
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent uses a stop bead as an intermediary element between the knot and the float. The stop bead distributes the tension forces and provides a smooth surface that reduces abrasion on the line. It acts as a mediator that maintains secure attachment without requiring excessively tight knots, thereby preventing memory formation and abrasion damage

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the float is made adjustable for tension and height, then the rig can adapt to different fishing conditions, but the device complexity increases

Engineering Contradiction:
ImproveadjustabilityVSAvoidrig complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the float assembly into distinct functional components: the float body, the stop bead for height adjustment, and the knot system for tension control. This modular segmentation allows each component to perform its specific function independently, providing adjustability without creating a complex integrated system

Inventive Principle:
Principle #1Segmentation

AI summary

A fishing rig is provided that combines differing combinations of assemblies to form a multipurpose fishing rig capable of fishing differing environments, species and differing fishing methods. The assemblies of the fishing rig include a main leader assembly that utilizes an inline float with a radial bore to attach to a side leader assembly. The side leader assembly includes at least a spacer bead and a cinch bead utilized for adjustable tensioning when attached to the main leader. A hook or lure assembly is provided and attached to the side leader assembly for either live bait, or lure fishing.
