Sliding rod holder assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fishing rods in boat cabins are difficult to secure in a locked and protected environment, especially during rough seas, as existing solutions fail to prevent rods from being knocked off shelves or out of cubby holes.
Innovation Solution
A sliding rod holder assembly with a locking member and tip supports, featuring a bottom-locking plate and top-locking plate with cutouts, and a cradle for securing fishing rods, which can be slid in and out for easy access and secure storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fishing rods are stored on open shelves or in cubby holes without locking mechanisms, then they are easily accessible and visible, but they can be knocked off or displaced during boat motion especially in rough seas
Solution Approach 1:
The rod holder assembly incorporates a sliding mechanism that allows the locking member to move between extended and retracted positions. When extended, the locking plates engage to secure the rod; when retracted, the rod is accessible for removal. This dynamic positioning resolves the contradiction between security and accessibility.
Solution Approach 2:
The locking mechanism is divided into separate components: a bottom-locking plate and a top-locking plate that can be independently positioned. This segmentation allows the rod to be securely held between two separate locking surfaces, providing reliable security while maintaining ease of access through the sliding action.
2Reliability
If a secure locking assembly is implemented to protect fishing rods during boat motion, then reliability of storage is improved, but the device complexity increases
Solution Approach 1:
The rod holder assembly combines multiple functions into a single integrated unit: the sliding mechanism, the locking plates, and the rod support structure are merged into one assembly. This consolidation provides secure storage through multiple locking points while avoiding the complexity of multiple separate mechanisms working together.
Solution Approach 2:
The sliding rod holder assembly serves multiple functions: it supports the fishing rod vertically, secures it laterally through the locking plates, and provides easy access through the sliding mechanism. This multi-functionality achieves reliable security without requiring separate devices for each function, thereby reducing overall complexity.
3Reliability
If the locking member is made robust to prevent rod displacement during rough seas, then security is improved, but the weight of the assembly increases
Solution Approach 1:
The locking mechanism applies localized securing forces at critical points: the bottom-locking plate engages the rod near the handle, and the top-locking plate engages near the reel. This localized quality approach provides robust security where needed most without requiring the entire assembly to be heavily constructed, thereby minimizing unnecessary weight.

AI summary
A fishing rod holder assembly is provided in a cabin of a boat. A rod holder locking member is mounted on a shelf in the cabin and is movable between an outboard position in the cabin and a position in the direction of the interior of the cabin. The locking member includes two plates hinged to each other to open and close, and having at least one cutout to receive and hold a rod handle therein. A rod tip holder is provided spaced from the rod holder locking member to support the tip of a fishing rod held within the assembly.
