Fishing Line Guide Attachment Foot Stepped Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing line guides face challenges in balancing aesthetic appearance and strength, as thin and narrow attachment feet for smooth thread winding are difficult to design without compromising structural integrity, and adhesive bonding issues arise from repeated expansion and contraction of the fishing rod.
Innovation Solution
A fishing line guide with stepped portions on its attachment foot, formed through an indenting process, which provides enhanced strength and allows for a smooth appearance by optimizing the width and thickness distribution, and an adhesive application method that ensures improved bonding force without damaging the guide's appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the attachment foot is made thin and narrow for smooth thread winding, then the aesthetic appearance is improved, but the strength and rigidity deteriorate
Solution Approach 1:
The attachment foot features stepped portions that create local variations in thickness, with thinner regions for aesthetic appearance and thicker regions for strength. This local quality differentiation allows the same component to satisfy both aesthetic and structural requirements simultaneously.
Solution Approach 2:
The stepped portions introduce a vertical dimension (height variation) to the attachment foot design, transforming a two-dimensional flat structure into a three-dimensional stepped structure. This dimensional change enables the attachment foot to maintain a narrow profile while providing structural reinforcement through increased thickness at specific locations.
2Force
If adhesive is applied to bond the fishing line guide, then the bonding force is improved, but cracking and aesthetic damage occur due to repeated expansion and contraction
Solution Approach 1:
The stepped portions modify the physical parameters of the attachment foot, creating expansion spaces that accommodate dimensional changes during fishing rod expansion and contraction. This parameter change allows the adhesive bond to remain intact while the structure flexes, preventing cracking.
Solution Approach 2:
The stepped portions create built-in expansion spaces that act as cushioning zones before stress can propagate to the adhesive bond. This beforehand cushioning absorbs the stress of repeated expansion and contraction, protecting the adhesive bond from cracking.
3Strength
If the attachment foot width and thickness are enlarged for strength, then the structural integrity is improved, but the aesthetic appearance deteriorates due to bulkiness
Solution Approach 1:
Rather than uniformly enlarging the attachment foot, the stepped portions provide localized thickness increases only where structural reinforcement is needed. This local quality approach maintains a narrow, aesthetic profile in visible areas while providing sufficient strength in load-bearing areas.

AI summary
According to an embodiment, there is provided a fishing line guide including a ring portion through which a fishing line passes and an attachment foot extending from the ring portion and attached to a fishing rod. The attachment foot may have stepped portions each formed on each of two side portions in a cross section of the attachment foot in a width direction of the attachment foot orthogonal to a longitudinal direction of the attachment foot.
