Flush-Mounted Rotatable Rod Holder for Flexible Boat Rod Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing rod holders for boats are non-adjustable, leading to issues such as entanglement, damage to rods and craft, and corrosion of fasteners, as they are fixed in one position and protrude laterally during travel.
Innovation Solution
A rotatable flush-mounted fishing rod holder with a rod holding tube and annular cover member that allows rotation relative to the gunwale, featuring a radially extending flange and friction member for secure attachment and adjustable rotation, enabling rods to be positioned optimally and reducing exposure to elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fishing rod holders are installed in a fixed non-adjustable position, then the structure is simple and easy to manufacture, but the rods cannot be repositioned to avoid entanglement, damage, or optimal fishing positions
Solution Approach 1:
The rod holder is designed with a rotatable mechanism that allows the holder to rotate about a vertical axis relative to the gunwale. This dynamic capability enables the rod to be repositioned to various angles (e.g., forward, aft, or abeam positions) without changing the overall holder structure, thus providing adaptability while maintaining structural simplicity.
Solution Approach 2:
The rod holder system is divided into distinct components: a fixed base plate attached to the gunwale, a rotatable holder body, and a rod-carrying tube. This segmentation allows the base to remain simple and fixed while the holder body can rotate independently, providing flexibility without complicating the entire structure.
2Object-affected harmful factors
If fishing rod holders are fixed in one position, then the structure is stable, but the rods protrude laterally outside the craft during travel which can result in damage to rods and/or the craft
Solution Approach 1:
The rotatable holder allows rods to be dynamically repositioned during travel to a forward or aft position, clearing them from the lateral path where they could cause damage. The holder can be easily rotated to accommodate different travel conditions without requiring complex mechanisms.
3Object-affected harmful factors
If fasteners are placed on top of the gunnel for rod holder attachment, then the installation is simple, but the fasteners are more exposed to the elements resulting in corrosion
Solution Approach 1:
The attachment system is segmented into a base plate that interfaces with the gunwale and a holder body that rotates above it. The fasteners are embedded in the base plate which can be positioned to minimize exposure, while the holder body remains above for rotational movement. This separation allows simple installation with protected fasteners.
4Reliability
If fishing rod holders are canted or inclined rearwardly in a fixed position, then the structure is simple, but the rods are in a compromised position when under load which can result in damage to rod and loss of catch
Solution Approach 1:
The holder can be rotated to position the rod at optimal angles relative to the direction of travel and loading conditions. This dynamic positioning allows the rod to be aligned properly when a fish strikes, improving reliability without requiring complex adjustment mechanisms - simply rotation about the vertical axis achieves the needed positioning.

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.
