Solution Overview

Problem

Current hard body and spoon-type fishing lures lack versatility in presentation changing and do not utilize naturally occurring vibrant colors, shapes, and patterns, requiring anglers to manually change lures, which is cumbersome and limits market choices.

Innovation Solution

A fishing lure with interchangeable inserts that engage via a snap-lock mechanism, allowing quick changes without removing the lure from the line, featuring various natural or synthetic attractants and adaptable to different lure types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If anglers use traditional hard body or spoon-type fishing lures, then the lures provide basic visual attraction, but the lures lack versatility in presentation changing and require manual removal from the line to change appearance

Engineering Contradiction:
Improvepresentation changing versatilityVSAvoidease of presentation changing
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The fishing lure is divided into two main segments: a reusable lure body and interchangeable inserts. The insert can be independently removed from and reattached to the lure body, allowing anglers to change the appearance and presentation of the lure without removing the entire lure from the fishing line. This segmentation enables quick swapping of different inserts to adapt to various fishing conditions and fish species.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lure body is designed with a universal insert slot that can accommodate multiple different inserts with varying outer surface characteristics (colors, patterns, textures). This multi-functionality allows a single lure body to serve multiple purposes by simply changing the insert, eliminating the need for multiple complete lures and simplifying presentation changes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If anglers change lures manually by removing and re-attaching, then complete lure replacement is achieved, but the process is cumbersome and time-consuming

Engineering Contradiction:
Improvepresentation changing capabilityVSAvoidtime for presentation changing
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

By segmenting the lure into a body and interchangeable inserts, the system allows anglers to change only the insert portion rather than the entire lure. The insert can be quickly detached from the insert slot and replaced with another insert, significantly reducing the time required for presentation changes compared to removing and re-attaching the complete lure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The insert is extracted as a separate, interchangeable component from the lure body. This extraction allows the insert to be independently swapped without affecting the lure body or requiring removal from the fishing line, enabling rapid presentation changes while minimizing time loss.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of manufacture

If traditional lure designs are used, then manufacturing simplicity is maintained, but the lures do not utilize naturally occurring vibrant colors, shapes, and patterns

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidnatural attractant variety
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The design segments the visual attractant elements into separate inserts that can be independently manufactured with diverse natural colors, patterns, and textures. Each insert can be produced using standard manufacturing processes, while the variety of natural attractants is achieved through producing multiple insert types that fit the universal insert slot.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The insert slot and catch mechanism are designed with specific local qualities (dimensions, tolerances, engagement features) that enable the insertion and retention of various inserts. This localized design allows the rest of the lure body to maintain manufacturing simplicity while the inserts provide the diverse natural attractant characteristics.

Inventive Principle:
Principle #3Local quality

AI summary

A fishing lure having interchangeable inserts includes a lure body having a front end, a rear end, a left side, a right side, a top side, and a bottom side. At least the left side, but in some embodiments also the right side, includes an insert slot with an opening proximate the rear end. The insert slot has at least one pair of opposing flanges. An insert engages the insert slot and has a catch at a forward end thereof adapted for engaging the snap aperture of the lure body. An outer surface of the insert with a natural attractant is visible through the insert slot between the flanges. The insert is preferably one of many available inserts that all have varying outer surface characteristics, such as color, pattern, texture, attachments, and the like. A fishing lure attachment cooperative with the inserts is used with existing fishing lures.
