Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing crankbait fishing lures are limited to operating at a single depth, requiring fishermen to carry multiple lures with different lip sizes to target fish at various depths, which is time-consuming and inconvenient.

Innovation Solution

An adjustable fishing lure with a movable lip that can be set to different positions within a slot on the lure body, using a locking mechanism that engages with teeth to resist loading and maintain the desired depth, allowing the lure to swim at various depths without changing lures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fishermen use multiple crankbait lures with different lip sizes to target different depths, then the ability to fish at various depths is improved, but the time required to change lures and the complexity of carrying multiple lures increases

Engineering Contradiction:

Improvedepth targeting capabilityVSAvoidtime to change lures

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The lip is made movable relative to the lure body through a slot and locking mechanism, allowing the lip position to be dynamically adjusted between multiple predetermined positions. This dynamic adjustment enables a single lure to perform the function of multiple lures with different fixed lip positions, resolving the contradiction by providing depth adaptability without requiring multiple separate lures

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

A single crankbait lure is designed to perform multiple functions by enabling the lip to assume different positions for targeting fish at various depths. The universal design allows one lure to replace multiple specialized lures, eliminating the need to carry and switch between multiple lures, thus reducing time loss while maintaining depth versatility

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If fishermen use multiple crankbait lures with different lip sizes to target different depths, then the ability to fish at various depths is improved, but the complexity of equipment increases

Engineering Contradiction:

Improvedepth targeting capabilityVSAvoidnumber of lures to carry

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Multiple depth-targeting functions that previously required separate lures are merged into a single lure design. The adjustable lip mechanism combines the functionality of multiple fixed-lip lures into one unit, reducing equipment complexity while maintaining the ability to target various depths

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If the lip position is made adjustable to enable fishing at various depths, then depth versatility is improved, but the structural complexity of the lure increases

Engineering Contradiction:

Improvedepth adjustabilityVSAvoidlure structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lure is segmented into distinct functional components: the lure body, the movable lip, the slot providing movement paths, and the locking member for position fixation. This segmentation allows each component to perform its specific function independently while working together as a unified adjustable system, managing structural complexity through functional decomposition

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Inventive Principle:

Principle #15Dynamics

4Adaptability or versatility

If the lip is made movable to different positions for depth adjustment, then depth versatility is improved, but the reliability of the connection under loading decreases

Engineering Contradiction:

Improvedepth adjustabilityVSAvoidlip connection stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The locking member is designed to proactively engage with the slot structure before loading occurs, preventing unintended lip movement. By establishing the locked position in advance and providing over-constraint through multiple contact points, the design cushions against the effects of loading that might otherwise cause unreliable connection or lip displacement

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

An adjustable depth fishing lure including a lip and a lure body is provided. The lip is partially received in a slot of the lure body and is movable to predetermined positions relative to the lure body. The lip may include an eyelet. The lip includes a locking member and the lure body includes a plurality of teeth. The locking member is configured to engage at least one of the teeth to fix the lip relative to the lure body at one of the predetermined positions. This engagement between the locking member and the teeth provides a rigid connection that resists loading applied to the lip by the fisherman pulling on the fishing line and/or a fish biting a hook connected to the lure body.
