Flexible Multi-Armed Fishing Lure with Rear Weight

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional multi-armed fishing lures with rigid wire arms are difficult to cast due to their telescoping design, leading to tangling issues when retrieving, as the weight at the front requires the lure to turn mid-air, causing line wraps and tangles.

Innovation Solution

A fishing lure with 4 flexible stainless steel wire arms and a central arm that can be adjusted for depth, featuring a changeable weight at the rear, allowing for easy casting and minimizing tangling by keeping baits separated through a staggered and spread design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the weight is positioned at the front of the lure, then the lure can be properly balanced for trolling, but the lure must turn mid-air during casting causing line wraps and tangles

Engineering Contradiction:

Improvetangle-free castingVSAvoidcasting performance

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent inverts the conventional weight positioning by placing the weight at the rear of the lure instead of at the front. This inversion allows the lure to cast naturally without requiring a mid-air turn, eliminating line wraps and tangles while maintaining proper trolling balance

Inventive Principle:

Principle #13The other way round (Inversion)

2Strength

If rigid wire arms are used in multi-armed lures, then the structure provides strength and stability, but the telescoping design makes casting difficult and causes tangling

Engineering Contradiction:

Improvearm structure strengthVSAvoidcasting ease

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The patent replaces rigid wire arms with flexible arms that can bend and flex during casting and retrieval. This flexibility eliminates the telescoping effect that causes tangling while maintaining sufficient strength to support baits and withstand fishing forces

Inventive Principle:

Principle #30Flexible shells and thin films

3Adaptability or versatility

If multiple baits are attached to arms without separation, then the lure can attract fish from multiple angles, but the baits become entangled during casting and retrieval

Engineering Contradiction:

Improvebait presentation capabilityVSAvoidtangle-free operation

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent employs asymmetric arm spacing and staggered bait positioning to ensure that multiple baits remain separated during casting and retrieval. The unequal spacing prevents baits from overlapping and tangling while still providing attractive presentation from multiple angles

Inventive Principle:

Principle #4Asymmetry

AI summary

The invention relates to a fishing lure made up of an epoxy resin head where the fishing line will connect, a number of flexible stainless steel camouflage wire arms coming out the center backside of the head horizontally to create different width spreads on the lure. These flexible wire arms eventually bend downward to create the height of the lure, or the vertical arms with staggered lengths to them. A number of different baits can be attached to each individual arm. The flexibility of the wire arms allows adjustment of lure to keep its original shape. A center arm with multiple sized changeable weights to the far rear of invention, and the advantage of adding another bait on the end after the weight.
