Replaceable Hook Carriage for Fishing Lure Elastomer Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing lures with permanently embedded hooks and weights are prone to damage, leading to unnecessary disposal of the entire lure, create unrealistic swimming motion due to excess elastomer, and pose environmental concerns with lead weights, while failing to release hooks from the lure when struck by a fish.
Innovation Solution
A fishing lure system featuring a carriage assembly with a retaining member and a hook positioned outside the elastomeric body, allowing the hook to be released when struck by a fish, with a weighted carriage component that can be reused and replaced, reducing elastomer volume for a more natural swimming motion and minimizing environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hooks and weights are permanently embedded inside the supple body, then the lure structure is stable and secure, but the entire lure must be disposed of when damaged, increasing loss of material and time
Solution Approach 1:
The lure is divided into separate replaceable components: a supple body, a weighted carriage, and hooks. The carriage can be removed from the body through a carriage passageway, and hooks can be removed from the carriage, allowing individual components to be replaced without discarding the entire lure.
Solution Approach 2:
The carriage is nested within the supple body when installed, with the carriage passageway allowing the carriage to be inserted and removed. The hooks are nested within the carriage, creating a hierarchical structure where components can be independently accessed and replaced.
2Strength
If a large volume of supple material is used to contain hooks and weights, then hooks and weights are protected from tearing the body, but friction increases and swimming motion becomes unrealistically large
Solution Approach 1:
The hooks and weights are extracted from the bulk of the supple body and placed into a separate carriage structure. This reduces the volume of supple material needed while maintaining protection for the hooks and weights, allowing for a more natural swimming motion with reduced friction.
Solution Approach 2:
The supple body is designed with localized flexibility - the rear portion can flex for natural swimming motion while the front portion maintains structural integrity to protect the carriage. The carriage itself provides localized reinforcement where hooks and weights are positioned.
3Reliability
If the hook will not release from the lure's eyelet when struck by a fish, then the hook remains securely attached, but the hook cannot be replaced or removed
Solution Approach 1:
The hook carriage is designed with dynamic characteristics - it can flex and move in response to fish strikes, allowing the hook to be released from the lure when needed. The spring wire configuration enables the carriage to adapt to different conditions, providing both secure attachment during fishing and release capability when required.
4Weight of moving object
If lead weights are used for proper weight compensation, then the lure sinks at the correct rate, but environmental harm increases due to toxic metal disposal
Solution Approach 1:
The weight material can be changed from lead to alternative materials such as tungsten, steel, or biodegradable options. The carriage design allows for easy replacement of weight components, enabling anglers to switch to environmentally friendly materials while maintaining the necessary weight compensation for proper lure sinking rate.

AI summary
A fishing lure system with an example having a two-part fishing lure having a replaceable hook-retainer carriage assembly which is removably insertable in an elastomeric body component. When configured as a two-part lure, the fishing lure may be configured with a flexible elastomeric body component with a precisely positioned preformed cavity in the head region for receiving a weighted hook-retainer carriage. The carriage may be inserted into the lure through a slit or passageway. The elastomeric bodies, hooks and weighted carriage assemblies of one example are independently removable and replaceable. The carriage assembly of one example includes an integral hook eye retaining loop and hook shank retainers which exit through passageways from the preformed cavity to the dorsal surface of the elastomeric body. The eyelet and retainers may be configured to position an upward pointing hook that is removably secured adjacent the outside dorsal surface of the lure.
