Angling Lure Secure Retention via Compression Rod
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing angling lures are prone to separation in aggressive aquatic environments, making them unreliable for fishing in water courses or at sea.
Innovation Solution
An angling lure design featuring a rigid head, a flexible body, and a hook with an attachment rod that compresses the body against the head, ensuring secure retention and easy assembly, along with openings for the hook and rod, facilitating tool-free assembly and reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lure components are made separable with simple connection means, then assembly and disassembly become easier, but the reliability of the connection deteriorates in aggressive aquatic environments
Solution Approach 1:
The lure is divided into separable components (head, body, hook) that can be easily assembled and disassembled by the user, while the connection between components is strengthened through the attachment rod's fixing portion that engages with the body's opening to prevent separation in water
Solution Approach 2:
The attachment rod is inserted through the body's opening and the hook's eyelet threads onto the rod, creating a nested arrangement where components fit within each other. The fixing portion of the rod engages with the body's opening to secure the connection while allowing easy assembly and disassembly
2Reliability
If the hook is firmly retained in the body, then fish retention improves, but the ease of replacing hooks deteriorates
Solution Approach 1:
The attachment rod serves as an intermediary element between the body and hook. The fixing portion of the rod engages with the body's opening to provide firm retention, while the free end allows the hook's eyelet to thread onto the rod, enabling easy hook replacement without tools
3Reliability
If the body is firmly clamped to the head, then the lure structure becomes more reliable in water, but the complexity of the connection mechanism increases
Solution Approach 1:
The attachment rod provides localized reinforcement at the connection point between body and head. The fixing portion engages with the body's opening at a specific location to provide firm clamping, while the rest of the structure remains simple and straightforward
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 design provides a secure and durable lure that remains assembled in aquatic conditions, allowing for repeated use without deterioration and improved fish retention due to the offset hook attachment and oscillatory movement, enhancing fishing effectiveness.
Implementation Method 1
the retaining portion being adapted to exert a force compressing the portion of the body disposed between the rear face of the head and the attachment rod so as to retain the body against the rear face of the head

AI summary
An angling has a rigid head with a rear face, a flexible body having a front end and a second end adapted to contact the rear face, a hook having an eyelet and a point, and an attachment rod having a first end fastened to the rigid head and a free second end. The attachment rod has a fixing portion onto which the eyelet is retained and a vertical retaining portion exerting a force compressing the rigid body so as to retain the rigid body against the rear face of the rigid head. The head and the body have a shape corresponding to a shape of bait.
