Fish Lure Lock Mechanism for Soft Plastic Bait Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for securing plastic lures to jig heads are temporary and prone to failure, especially when the lure is made of soft plastic or infused with salt, as they often engage the lure at weak points and do not provide long-lasting attachment.
Innovation Solution
A fish lure lock mechanism that secures the lure to a jig head using snap or lock arms with barbs that penetrate the lure's exterior, combined with a compression member like an O-ring to ensure stability and prevent sliding, allowing for adjustable attachment to different lure diameters and easy removal without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods (molded lead barb, ring, metal wire hook, or adhesive) are used to secure the lure to the jig head, then the lure can be attached initially, but the attachment becomes temporary and fails quickly, especially with soft plastic lures or salt-infused lures
Solution Approach 1:
The patent introduces a collar as an intermediary component between the lure and jig head. The collar engages the lure body at its strongest point (larger cross-sectional diameter) and provides a secure attachment interface with the jig head, distributing forces evenly and preventing the lure from sliding or detaching, thereby significantly improving attachment durability and duration
Solution Approach 2:
The invention divides the attachment system into separate functional components: the collar that secures the lure and the jig head structure that holds the collar. This segmentation allows each component to be optimized independently - the collar can be designed to engage the lure at its strongest point while the jig head provides structural support, resulting in a more reliable and long-lasting attachment
2Ease of manufacture
If the lead barb, ring or metal wire hook engages the lure at a smaller cross-sectional diameter, then the lure can be secured, but it engages at a weak point on the lure reducing overall strength
Solution Approach 1:
The collar is specifically designed to engage the lure at its larger cross-sectional diameter, which is the strongest portion of the lure body. This localized engagement at the optimal position maximizes the attachment strength by distributing mechanical stresses across the strongest available area of the lure, rather than concentrating forces at weaker points
3Ease of operation
If adhesive is used to secure the lure to the jig head, then initial attachment is achieved, but it only provides a temporary fix that fails over time
Solution Approach 1:
The patent replaces the chemical bonding mechanism of adhesives with a mechanical fastening system using the collar. The collar utilizes mechanical interference fit and friction forces to secure the lure to the jig head, providing a reliable and durable attachment that does not degrade over time like adhesive bonds, while still being easy to apply and remove
4Adaptability or versatility
If the lure is made from soft plastic or infused with salt, then the lure has desirable fishing properties, but it becomes easily torn and difficult to secure
Solution Approach 1:
The collar is designed to work effectively with flexible soft plastic lures by utilizing friction and compression forces. The collar's internal geometry creates a secure fit that accommodates the flexibility of soft plastic while preventing the lure from sliding or detaching, maintaining attachment security despite the lure's material properties
