Weighted Lures Using Dispersed Metal Particles in Plastisol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fishing lures often require additional weights, which can be toxic and prone to falling off, leading to environmental pollution and inefficiencies in weight distribution as lure sizes change.
Innovation Solution
Development of weighted lures made from synthetic materials like plastisol, incorporating dispersed metal particles such as tungsten or bismuth, which provide inherent weight without the need for external weights and ensure consistent density throughout the lure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lead weights are attached to the line or lure, then the lure sinks to the desired depth, but the weights are toxic and can fall off causing environmental pollution
Solution Approach 1:
The patent combines the weighting function directly into the lure body by dispersing weighting substances (such as metal particles or dense materials) throughout the plastisol matrix. This integration eliminates the need for separate lead weights that can detach and pollute water, while maintaining the lure's sinking capability. The weighting function is merged with the structural material, ensuring the weight cannot separate from the lure.
Solution Approach 2:
The patent replaces toxic lead weights with non-toxic alternative weighting substances dispersed in the lure body. This conversion transforms the harmful aspect (toxicity) into a beneficial one (environmentally safe), while still achieving the desired sinking function. The weighting substances used are specifically selected to be non-toxic alternatives to lead.
2Reliability
If traditional external weights are used, then the lure can sink, but the weights may fall off during fishing
Solution Approach 1:
The weighting substances are dispersed and embedded within the plastisol matrix of the lure body, creating a unified structure where the weight becomes an integral part of the lure. This merging ensures the weight cannot detach during fishing operations, as it is distributed throughout the material rather than attached as a separate component.
Solution Approach 2:
The patent creates a composite material structure by dispersing weighting substances (such as metal particles, glass beads, or other dense materials) within the plastisol matrix. This composite approach combines the structural properties of plastisol with the density properties of the weighting substances, creating a unified material that maintains both shape and weight permanently.
3Adaptability or versatility
If the size of the lure changes, then different fishing scenarios are addressed, but the amount of weights needed changes requiring adjustments
Solution Approach 1:
The patent applies different concentrations or types of weighting substances to different regions or sizes of lures during the manufacturing process. By controlling the dispersion density of weighting particles within the plastisol, each lure size automatically achieves the appropriate weight for its intended application, eliminating the need for post-manufacturing weight adjustments.
Solution Approach 2:
The patent varies the concentration, type, or distribution of weighting substances based on the desired lure size and intended fishing application. By changing these material parameters during manufacturing, the lure automatically achieves the correct weight-to-size ratio, providing adaptability across different lure sizes without requiring separate weight adjustment procedures.
4Shape
If buoyant materials are used for the lure body, then the lure floats to the surface, but some fish may not see or be interested in surface lures
Solution Approach 1:
The patent controls the overall density of the lure by adjusting the concentration and distribution of weighting substances within the plastisol matrix. By varying these material parameters, the lure can be designed with specific buoyancy characteristics - either floating, suspended, or sinking - depending on the intended fishing application and target fish behavior.

AI summary
A weighted lure can include a body formed from plastisol and a weighted portion formed from a high density plastisol. The high density plastisol can include plastisol and a weighting substance dispersed within the plastisol. The weighted portion can be encased by the body. The weighted lure also can include an air pocket or air chamber formed in the body.
