Segmented Fishing Lure with Articulated Linkages for Aerodynamic Casting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing lures lack the ability to be both aerodynamically efficient during casting and realistically simulate the movement of a bait fish in water, as they are either non-expandable or non-collapsible, limiting their casting distance and fish-attracting effectiveness.
Innovation Solution
An expandable, collapsible, segmented fishing lure design that uses articulated linkage connectors allowing segments to move longitudinally, vertically, and horizontally, mimicking the motion of a bait fish, while collapsing during flight to enhance aerodynamics and expanding in water to simulate wiggling movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the lure is designed with fixed non-expandable body, then the structure is simple and reliable, but the casting distance is limited due to poor aerodynamics
Solution Approach 1:
The lure body is divided into multiple segments connected by articulated linkages, allowing each segment to move independently. This segmentation enables the lure to collapse into a compact aerodynamic shape during casting while expanding to simulate bait fish movement in water, resolving the contradiction between casting distance and structural complexity.
Solution Approach 2:
The lure transitions from a static fixed body to a dynamic structure that can change its configuration based on the operating environment. The articulated linkages enable the lure to adapt its shape - collapsing for aerodynamic casting and expanding for realistic water movement - thereby improving casting distance without permanently increasing structural complexity.
2Reliability
If the lure segments are separated to simulate bait fish movement, then the fish-attracting effectiveness is improved, but the aerodynamic performance during casting deteriorates
Solution Approach 1:
The lure employs dynamic configuration changes through articulated linkages that allow segments to collapse together during casting to minimize aerodynamic resistance, then separate and articulate in water to simulate bait fish movement and attract fish. This dynamic adaptation resolves the contradiction between aerodynamic performance and fish-attracting effectiveness.
Solution Approach 2:
The physical parameters of the lure (segment spacing, body configuration) change based on the operating environment. During casting, segments are close together creating a streamlined shape with low aerodynamic resistance. In water, segments separate and articulate to create realistic movement patterns, thereby optimizing for different functions without compromise.
3Strength
If the lure uses rigid connected segments, then the structural strength is high, but the ability to simulate wiggling motion in water is reduced
Solution Approach 1:
The lure body is segmented with articulated linkages that provide both structural integrity and movement capability. The connections are designed to maintain strength while allowing controlled articulation, enabling the lure to simulate wiggling motion in water without compromising structural strength during casting or use.
Solution Approach 2:
The articulated linkages function as flexible connections between segments, allowing controlled movement while maintaining overall structural strength. The linkage design provides flexibility for motion simulation while the segmented body maintains sufficient rigidity for casting and water resistance, resolving the contradiction between strength and adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The lure achieves increased casting distance and accuracy due to its aerodynamic shape during flight and a lifelike swimming action in water, capable of landing larger fish without breaking, thanks to its unique articulated linkage system.
Implementation Method 1
the friction of the air against the rear (now after pivoting being the forward end) distal end of the forward advancing lure pushes that forward-facing, previously 'rear' segment rearward
Implementation Method 2
the independent movement of the respective individual segments under hydraulic tension includes movement about the longitudinal axis, about the horizontal axis, about the respective segment vertical axes

AI summary
An aerodynamic fish lure facilitates collapsible closing of the lure for farther casting distance and accuracy when cast off in the air. The air casting event causes the lure's jointed segments to contract in length together in the air and then to expand in length as the lure hits the water. Then the lure either skims along the surface of the water or is submerged under the water and can pivot in two or more axial directions, or at any angles therebetween. Connectors connect the segments, and retract in or out of respective recesses in the respective segments, which are designed to permit the collapsing of the length of the lure in the air as well as the lure's expansion or contraction in any axial direction or angle therebetween, in length in the water. The segments also laterally pivot, imitating wiggling of lure bait on or in the water.
