Fishing Rod Multi-Strip Composite Design for Diameter Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing rod designs have limited flexibility in shape and strength due to the use of pre-impregnated composite fibers that restrict the rod's configuration, making it difficult to adapt to changes in diameter and optimize both design freedom and structural integrity.
Innovation Solution
The fishing rod features a rod body composed of multiple strips with distinct narrowing sections that overlap, allowing for a combination of different prepregs and layer configurations, including a small diameter part, a large diameter part, and an expanding part, which enhances design freedom and strength by using symmetric and asymmetric strip configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If prepreg is wound more than once on a mandrel to form the rod body, then the rod body can be formed with composite fiber structure, but the shape and strength of the rod body are restricted
Solution Approach 1:
The rod body is divided into multiple strips (first strip, second strip, third strip, fourth strip) instead of using a single continuous prepreg winding. Each strip can be independently configured with different widths, materials, and winding patterns, enabling customized strength and shape characteristics for different sections of the rod body while maintaining manufacturing feasibility.
2Adaptability or versatility
If the diameter of the rod body significantly changes, then adaptability to different configurations is improved, but it becomes difficult to maintain structural integrity with conventional single-layer prepreg
Solution Approach 1:
Different strips are assigned different widths and material properties to match local requirements at different diameters. For example, strips at larger diameter sections can be wider to provide sufficient circumferential coverage, while strips at smaller diameter sections are narrower. This local customization maintains structural integrity across varying diameters while achieving diameter adaptability.
3Adaptability or versatility
If separated pieces are used to form the rod body layer, then adaptability to diameter changes is improved, but the degree of freedom in design can be further improved
Solution Approach 1:
The multi-strip configuration serves multiple functions simultaneously: it enables diameter adaptability through variable strip widths, provides design freedom through independent material selection for each strip, maintains structural integrity through overlapping arrangements, and facilitates manufacturing through standardized strip preparation processes. This universal approach resolves multiple requirements without proportionally increasing complexity.

AI summary
A fishing rod includes a rod body. The rod body includes a plurality of strips, each of the plurality of strips includes a tip strip portion having a first narrowing section which gradually narrows in width towards the rod end side and an end strip portion having a second narrowing section which gradually narrows in width towards the rod tip side. At least a part of the first narrowing section and at least a part of the second narrowing section overlap with each other to form an overlapping portion.
