Fishing Lure Line-Eye Restraint for Stable Water Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The movement of a lure's line eye relative to the body results in undesired movement patterns in water, leading to instability and potential distortion.
Innovation Solution
A lure design featuring a plate member with a line eye, restricted by a body with a restricting portion that includes first and second restricting parts, and pins inserted into holes to stabilize the plate member's movement, enhancing rigidity and preventing deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the plate member is freely attached to the body without restriction, then the ease of manufacture is improved, but the stability of the lure's movement in water deteriorates
Solution Approach 1:
The restricting portion is divided into multiple restricting parts (first restricting part, second restricting part, etc.) that independently constrain different aspects of plate member movement. This segmentation allows the restriction mechanism to be integrated into the body structure without complex assembly steps, maintaining ease of manufacture while achieving stable movement control in water.
Solution Approach 2:
The restricting portion is merged with the body structure, forming an integrated component that simultaneously provides structural support and movement restriction. This merging eliminates separate restriction mechanisms, simplifying manufacturing while ensuring the plate member maintains stable positioning during lure operation in water.
2Stability of the object's composition
If the restricting portion is added to prevent plate member movement, then the stability of the lure's movement in water is improved, but the device complexity increases
Solution Approach 1:
The restricting portion is merged with the body structure, forming an integrated component that simultaneously provides structural support and movement restriction. This merging eliminates separate restriction mechanisms, simplifying the overall device while ensuring the plate member maintains stable positioning during lure operation in water.
Solution Approach 2:
The body structure serves multiple functions: it provides the main structural framework, houses the restricting portion, and constrains the plate member movement. This multi-functionality reduces the need for additional specialized components, maintaining simplicity while achieving stable movement control.
3Stability of the object's composition
If the plate member is rigidly fixed to the body, then the stability of movement in water is improved, but the rigidity of the plate member against external force deteriorates
Solution Approach 1:
The restricting portion provides localized constraint at specific critical positions (forward and rearward of the line eye) where movement control is most needed. The plate member maintains its inherent rigidity and flexibility properties elsewhere, allowing it to resist external forces like tensile load while preventing unwanted movement at the attachment interface.
Solution Approach 2:
The restricting portion allows controlled movement in specific directions while maintaining rigidity in others. The first and second restricting parts create a dynamic constraint system that permits the plate member to flex and absorb external forces while preventing displacement that would affect lure movement stability.
