Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing fishing rod holders installed in boats are non-adjustable, leading to issues such as entanglement, damage to rods and crafts, and corrosion of fasteners, as well as compromised rod positions during fishing.

Innovation Solution

A rotatable flush-mounted fishing rod holder with a rod holding tube and annular flange that allows for adjustable positioning, featuring a radially extending flange and cover member for secure attachment to the gunwale while enabling rotation, and optional features like friction members and tensioning elements for ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed non-adjustable rod holder is used, then the structure is simple and manufacturing is easy, but the rod cannot be repositioned leading to entanglement and damage

Engineering Contradiction:

Improverod position adjustabilityVSAvoidholder structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rod holder transitions from a fixed static structure to a dynamic rotatable structure. The tube can rotate within the gunwale mounting, allowing the rod position to be adjusted dynamically based on fishing conditions, boat movement, and rod length, while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #15Dynamics

2Object-affected harmful factors

If rods are held in a fixed canted position, then the holder structure is simple, but rods protrude laterally causing damage to rods and craft

Engineering Contradiction:

Improverod and craft damageVSAvoidrod access for re-rigging

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The rotatable tube allows rods to be positioned dynamically - can be angled rearwardly during travel to prevent lateral protrusion and damage, and rotated to accessible positions when re-rigging or fish removal is needed, eliminating the need for complete rod removal.

Inventive Principle:

Principle #15Dynamics

3Object-affected harmful factors

If fasteners are exposed on top of the gunnel, then installation is simple, but fasteners are exposed to elements causing corrosion

Engineering Contradiction:

Improvefastener corrosionVSAvoidinstallation complexity

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The rod holder tube is nested within the gunwale opening, with the mounting fasteners positioned inside the gunwale structure rather than exposed on top. The tube extends through the gunwale with its upper end positioned within the opening, concealing the fasteners from direct exposure to weather elements while maintaining secure installation.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A rotatable flush mounted fishing rod holder including a rod holding tube with an annular flange extending radially from an upper end thereof, and an annular cover member to attach relative to a surface over the annular flange to hold the rod holding tube to the surface but allow rotation of the rod holding tube relative thereto.
