Segmented Reel Seat Grip Reduces Fishing Rod Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fishing rods in existing designs face issues of increased weight and size due to solid reel seats and weight increments from bonding processes in reel seat and grip structures.
Innovation Solution
A reel seat grip member comprising a fairing portion and a buttock portion, attached via adhesion, fitting, or mechanical fastening, with movable hoods and attachment members made of carbon fiber reinforced plastic, allowing for lightweight, compact, and design-freedom-enhancing configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a solid reel seat is injection-molded on an outer peripheral surface of a cylindrical reinforcing resin layer, then the reel seat structure is simplified and integrated, but the weight increases and the size becomes huge
Solution Approach 1:
The reel seat is divided into a reel seat main body and a separate grip portion. The grip portion is formed by increasing the diameter of the rear portion of the hollow rod body, while the reel seat main body is injection-molded separately and then assembled. This segmentation allows weight reduction by avoiding a solid continuous structure while maintaining structural integrity.
Solution Approach 2:
The reel seat main body is inserted into the grip portion, forming a nested structure where the reel seat main body is housed within the grip portion. This nesting approach allows the components to share space efficiently, reducing overall size and weight while maintaining structural strength.
2Stability of the object's composition
If the rear grip rod body and reel seat main body are joined integrally by increasing diameter, then structural integration is achieved, but weight increases due to bonding requirements
Solution Approach 1:
The structure is segmented into distinct components (rod body, grip portion, reel seat main body) that can be manufactured separately and assembled. This avoids the need for heavy bonding materials while maintaining structural integration through precise fitting and mechanical connection.
Solution Approach 2:
The grip portion and reel seat main body are combined through assembly rather than bonding. The reel seat main body is inserted into the grip portion, creating a unified structure without requiring additional bonding materials, thus reducing weight while maintaining structural stability.
3Strength
If a solid reel seat structure is used, then structural strength is ensured, but the size becomes huge and weight increases
Solution Approach 1:
The reel seat is segmented into a reel seat main body and grip portion, allowing each component to be optimized for its specific function. The reel seat main body provides structural strength for reel mounting, while the grip portion provides ergonomic handling, reducing overall volume while maintaining necessary strength.
Solution Approach 2:
Different portions of the reel seat structure have different properties optimized for their specific functions. The reel seat main body has higher strength for structural support, while the grip portion has optimized dimensions for handling. This local optimization reduces overall volume while maintaining strength where needed.

AI summary
A reel seat grip member, a reel seat grip structure, and a fishing rod that are lightweight, have a compact hood, and have a high degree of freedom in design. A reel seat grip member includes a fairing portion, and a buttock portion connected to the fairing portion. The fairing portion is attached at least one hood of a pair of hoods for fixing a reel leg of which one end is provided on a rod body, and the buttock portion is attached to the rod body via an attachment member of which one end is provided on the rod body.
