Segmented Diving Lip for Horizontal Lure Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diving lips on fishing lures do not replicate the natural movement of live bait fish, as they tend to move angularly rather than horizontally through the water, failing to mimic the realistic motion of live bait fish.
Innovation Solution
A longitudinally extending diving lip with rear, intermediate, and front sections, each with specific downwardly inclined upper surfaces and a connector loop, designed to maintain the lure's longitudinal axis horizontal while moving through the water, incorporating convex and concave transition zones and keel formations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple planar diving lip is used, then the lure can be easily manufactured and positioned at desired depth, but the lure moves angularly rather than horizontally through the water
Solution Approach 1:
The diving lip is divided into three distinct sections (rear, intermediate, and front sections) with different angular orientations. Each section has a specific upper surface angle that works together to guide the lure through horizontal movement while maintaining ease of manufacture as a single integrated component
Solution Approach 2:
Different portions of the diving lip have different angular characteristics - the rear section has a first downward angle, the intermediate section has a second larger downward angle, and the front section has a third smallest downward angle. This local variation in angular quality allows the structure to guide the lure horizontally while remaining manufacturable
2Speed
If the diving lip projects at a steep downward angle, then the lure reaches desired depth quickly, but the lure cannot move horizontally through the water at that depth
Solution Approach 1:
The diving lip is designed to perform different functions at different stages of movement - initially driving the lure downward at steep angles, then transitioning to guide horizontal movement at the target depth. The multi-sectional design with varying angles enables this dynamic functional transition
Solution Approach 2:
The diving lip is segmented into rear, intermediate, and front sections with progressively shallower angles. This segmentation allows the steeper rear portion to drive initial descent while the shallower front portion guides horizontal movement, resolving the contradiction between descent speed and horizontal capability
3Reliability
If the diving lip is designed to drive the lure downward, then the lure reaches desired depth, but the lure does not mimic natural live bait fish movement
Solution Approach 1:
Each section of the diving lip has a specifically engineered angular quality that contributes to natural movement. The varying angles across sections create a progressive guidance effect that mimics how live bait fish move through water, while the overall structure maintains reliable depth control
Solution Approach 2:
The upper surfaces of the diving lip sections are designed with curved transitions rather than sharp angles. This curvature creates smooth water flow and natural movement patterns, making the lure more realistic while maintaining depth control reliability

AI summary
The diving lip projects from the front of a fishing lure that has a longitudinal axis and a fishing line connecting loop. The diving lip has rear, intermediate and front sections. Each of the sections has an upper surface. The fishing line connecting loop is positioned between the rear and intermediate upper surfaces. The rear upper surface extends at a downwardly inclined angle α relative to a plane that is approximately parallel to the longitudinal axis of the lure. The intermediate upper surface extends at a downwardly inclined angle β relative to another plane that is approximately parallel to the lure's longitudinal axis. The angle β is larger than angle α. The front section extends approximately parallel to the lure's longitudinal axis.
