Segmented Shrimp Lure with Weighted Head and Inverted Hook
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial shrimp lures fail to accurately mimic the appearance and movement of a live shrimp, particularly in emulating a horizontal configuration, realistic fleeing action, and durability for multiple uses, with most designs being static or semi-static and lacking a rearward-facing hook point.
Innovation Solution
A shrimp lure with a weighted head and thorax region, counterbalancing abdominal and tail sections, and a precise line attachment point, featuring a segmented, movable abdominal region that mimics the natural curvature and movement of a fleeing shrimp, with a rearward-facing hook point and optional hollow chambers for noise production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a solid body lure configuration is used to simplify construction, then manufacturing ease is improved, but the ability to mimic natural shrimp curvature and movement is worsened
Solution Approach 1:
The lure is divided into multiple segments including a head section, thorax section, and multiple abdominal sections that can move independently. This segmentation allows the abdominal region to curve and flex naturally while maintaining manufacturing feasibility through modular construction
Solution Approach 2:
The abdominal sections are designed to be movable relative to each other, enabling dynamic curvature and flexing motions that mimic a live shrimp's natural movements. This transforms the static solid body into a dynamic structure that adapts its shape during retrieval
2Ease of manufacture
If the hook point is positioned forward on the lure, then attachment simplicity is improved, but the ability to mimic a fleeing shrimp's rearward orientation is worsened
Solution Approach 1:
Instead of positioning the hook point at the conventional forward location, the hook is inverted and positioned at the rear end of the lure with the point facing backward. This unconventional placement accurately mimics the rearward-oriented posture of a fleeing shrimp while still allowing for practical attachment
3Shape
If the lure is designed to curve downward during retrieval to mimic fleeing motion, then realism is improved, but maintaining horizontal orientation during casting and descent becomes more difficult
Solution Approach 1:
The lure transitions from a stable horizontal configuration during casting and descent to a dynamic curved configuration during retrieval. The movable abdominal sections allow the lure to adapt its shape based on the retrieval motion, curving downward when pulled back to mimic fleeing while maintaining horizontal stability when suspended or descending
Solution Approach 2:
The head and thorax sections are weighted to counterbalance the abdominal sections, creating a seesaw effect that helps maintain horizontal orientation during casting and descent. This counterbalancing allows the weighted front to stay level while the lighter abdominal region can curve naturally during retrieval

AI summary
The present invention evidences an artificial shrimp lure constructed of a solid head and thorax region that is coupled to a jointed and segmented abdomen region comprised of tethered segments which closely mimic the natural curvature and inward curling exhibited by a fleeing shrimp, where the eyelet of an internalized hook is precisely at the weighted midpoint of the lure, dorsally, the hook shaft is internalized and the hook point projects upward and rearward facing above the lures head. The artificial shrimp lure is capable, through eyelet placement and weighting, of maintaining a largely horizontal orientation upon casting and descent and displays an inward curving of the jointed and segmented abdomen region upon retrieval and ascent.
