Segmented Reel Seat Design for Weight Reduction and Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reel seats face challenges in achieving a balance between good gripping properties and weight reduction, often resulting in increased weight or reduced strength due to uneven thickness and molding failures when trying to optimize for either factor.
Innovation Solution
A divided structure reel seat design, where a first main body made of a strong material like plastic composite with glass or carbon fiber provides strength, and a second main body made of lighter materials like ABS or elastomer enhances gripping comfort and reduces weight by allowing for efficient weight reduction without compromising strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the thickness of the reel seat main body is increased to improve gripping property, then gripping comfortability is improved, but weight is increased and molding failure due to uneven thickness more easily occurs
Solution Approach 1:
The reel seat main body is divided into two separate main bodies: a first main body made of strong material (plastic composite with glass fiber or carbon fiber) and a second main body made of lighter material (resin such as ABS and nylon, or elastomer, rubber). This segmentation allows each part to be optimized independently for its specific function, resolving the contradiction between gripping comfort and weight reduction.
Solution Approach 2:
Different parts of the reel seat are made with different material properties: the first main body uses high-strength material for structural integrity, while the second main body uses lighter material for gripping comfort and weight reduction. This local differentiation of material quality allows simultaneous optimization of strength and weight characteristics.
2Weight of moving object
If punched portions are increased and diameter is reduced to achieve weight reduction, then weight is reduced, but sufficient strength cannot be ensured
Solution Approach 1:
The reel seat is segmented into two main bodies with different material properties. The first main body made of strong material (plastic composite with glass fiber or carbon fiber) ensures sufficient strength even with reduced diameter and increased punched portions, while the second main body provides weight reduction.
Solution Approach 2:
The first main body uses composite materials (plastic composite with glass fiber or carbon fiber) that provide high strength-to-weight ratio, enabling weight reduction through punched portions while maintaining sufficient strength. The combination of different composite materials in the two main bodies resolves the strength-weight contradiction.
3Strength
If the reel seat is made of strong material to ensure sufficient strength, then strength is ensured, but weight reduction is difficult to achieve
Solution Approach 1:
The reel seat is divided into two main bodies: the first main body made of strong material (plastic composite with glass fiber or carbon fiber) for strength, and the second main body made of lighter material (resin such as ABS and nylon, or elastomer, rubber) for weight reduction. This segmentation allows simultaneous achievement of strength and weight reduction goals.
Solution Approach 2:
Different regions of the reel seat use different material qualities: the first main body uses high-strength material where structural integrity is critical, while the second main body uses lighter material where weight reduction is prioritized. This local quality differentiation resolves the strength-weight trade-off.

AI summary
A reel seat has a good handling property and good gripping comfortability at the time of gripping and holding a fishing rod with a fishing reel, further, the reel seat with which weight reduction is efficiently achieved. A seat main body of a reel seat has a divided structure of a first main body including a part where a reel foot mounting portion, a fixed hood, and a moving hood are arranged, the first main body being formed in a tubular shape secured on an outer peripheral surface of a fishing rod, and a second main body made of a material having strength equal to or less than the first main body, the second main body being disposed on and fixed to a surface of the first main body.
