Fishing Rod Handle Protuberance for Reduced Casting Hand Fatigue

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing fishing rod handles do not effectively improve casting ability, lead to hand fatigue and pain, and are difficult to hold, especially for users with diminished hand and arm function.

Innovation Solution

A fishing rod handle with an angled circumferential protuberance that provides support to the hand, reducing the need for a tight grip and enhancing leverage for improved casting and reduced fatigue.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a standard cylindrical fishing rod handle is used, then the handle is simple in design and easy to manufacture, but it causes hand fatigue and pain during casting

Engineering Contradiction:

Improvehand comfort during castingVSAvoidhandle structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies local quality by adding a circumferential protuberance at a specific location on the handle. This protuberance creates a localized support surface that contacts the heel of the user's hand, providing ergonomic support exactly where needed during casting without complicating the entire handle structure. The rest of the handle maintains its simple cylindrical form.

Inventive Principle:

Principle #3Local quality

2Reliability

If a tight grip is maintained on the handle, then control of the fishing rod is improved, but hand fatigue and pain increase

Engineering Contradiction:

Improvecontrol of fishing rodVSAvoidhand fatigue

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The circumferential protuberance acts as an intermediary support structure between the user's hand and the handle. It provides a fixed reference point (the front face of the protuberance) that supports the heel of the hand, allowing the user to maintain rod control through leverage and body mechanics rather than through tight gripping, thereby reducing hand fatigue.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Power

If the handle is designed for basic grasping, then manufacturing is simple, but casting power and accuracy are limited

Engineering Contradiction:

Improvecasting powerVSAvoidhandle design

Core Design Contradiction:

PowerVSDevice complexity

Solution Approach 1:

The patent applies dimensionality change by adding a circumferential dimension to the otherwise simple cylindrical handle. The protuberance extends around the circumference of the handle, creating a three-dimensional support feature that provides both structural integrity and ergonomic functionality, enabling improved casting power without requiring a completely complex redesign.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A handle for a fishing rod, said handle having a grip and one or more angled circumferential protuberances, with each angled circumferential protuberance located on the grip between the opposite ends of the handle, and with each angled circumferential protuberance configured to provide a support to a user's hand grasping the handle for purposes of casting.
