Adjustable Fishing Rod Butt Hinge for Mechanical Advantage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing rods lack an adjustable butt end that can adapt to different fishing applications, such as fighting large and powerful fish, where a static design fails to provide the necessary mechanical advantage and flexibility.
Innovation Solution
An adjustable butt and reel seat assembly featuring a hinge that locks elongate members in linear or curvilinear relationships, with annular hoods and a nut system to secure the reel, allowing for adjustable angles and accommodating various reel sizes, and optionally incorporating a gimbal for secure mounting on a boat or fighting belt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a static butt end design is used, then the structure is simple and easy to manufacture, but it cannot adapt to different fishing applications and provides insufficient mechanical advantage for fighting large fish
Solution Approach 1:
The butt end incorporates a hinge mechanism that allows it to transition between a linear configuration for normal fishing and a curvilinear angled configuration for fighting large fish. This dynamic adjustment capability enables the same structure to adapt to different fishing scenarios, resolving the contradiction between simplicity and adaptability.
Solution Approach 2:
The butt end is divided into multiple segments (first and second elongate members) that can be independently positioned relative to each other through the hinge mechanism. This segmentation allows the structure to be reconfigured for different fishing applications while maintaining overall structural integrity.
2Strength
If a fixed linear butt design is used, then the manufacturing is straightforward, but it cannot provide the necessary mechanical advantage for fighting powerful fish
Solution Approach 1:
The hinge mechanism enables the butt end to be manufactured in a simple linear form that can be easily fabricated, yet provides the capability to achieve a curvilinear configuration when needed for fighting powerful fish, thus resolving the contradiction between ease of manufacture and fighting strength.
Solution Approach 2:
The butt end's geometric parameters (linear vs. curvilinear shape) can be changed through the hinge mechanism without requiring complex manufacturing processes. The same simple components can achieve different geometric configurations to provide necessary mechanical advantage for fighting fish.
3Weight of moving object
If the butt end is made from lightweight materials like aluminum, then the rod is more comfortable and durable for extended fishing, but the structural strength may be compromised
Solution Approach 1:
The butt end utilizes high-strength lightweight materials such as aluminum or aluminum alloys that provide sufficient structural strength for fishing applications while significantly reducing the weight compared to traditional materials. The hinge mechanism and elongate member design compensate for any potential strength limitations through optimized geometric configuration.

AI summary
A fishing rod butt for use with a rod blank and a fishing reel includes a first elongate member hingeably attached to a second elongate member. In this manner, the butt can be configured to have a curvilinear shape or a linear shape depending on the intended fishing application. Also disclosed is an adjustable reel seat assembly.
