Multi-portion Clamp for Fishing Rods Without Reel Seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing rods without a reel seat lack a sturdy mechanism to securely attach fishing reels, especially for handling large fish that can weigh over 200 pounds, as existing reel-to-rod clamps rely on insufficient two-screw clamping forces.
Innovation Solution
A clamp design featuring an elongate first portion with four flanges and a concave surface, along with two independent second portions with flanges and concave surfaces, engages the fishing rod handle to securely hold reel assembly flanges, utilizing multiple fasteners for enhanced strength and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional two-screw clamps are used to attach reels to rods without reel seats, then the device complexity is reduced and ease of manufacture is improved, but the clamping force and strength are insufficient for handling large fish
Solution Approach 1:
The clamp is divided into multiple independent portions (first portion with four flanges, second portions with flanges) that can be separately positioned on opposite sides of the rod handle. Each portion independently contributes to the clamping force, allowing the system to achieve high strength through distributed multiple attachment points rather than relying on a single complex clamping mechanism.
Solution Approach 2:
The clamp combines multiple fasteners (screws/bolts) working together across multiple flanges and portions to create a unified clamping system. The first portion and second portions are merged through the rod handle to form a complete attachment system that distributes and multiplies the clamping force across the reel assembly flanges.
2Reliability
If multiple fasteners and portions are used to increase clamping strength, then the strength and reliability are improved, but the ease of manufacture and device complexity increase
Solution Approach 1:
The clamp portions and flanges are designed with universal functionality to work with various reel assembly flanges and rod handle configurations. The concave surfaces engage the rod handle while the flanges interface with standard reel mounting features, allowing a single clamp design to securely attach different reel types without requiring custom-manufactured components for each application.
Solution Approach 2:
Different portions of the clamp have specialized local features optimized for their specific functions: the first portion has four flanges for primary attachment, the second portions have flanges for secondary attachment, and concave surfaces are positioned to engage the rod handle. Each local feature is precisely designed for its specific mechanical role, improving overall reliability while maintaining manufacturability through standardized local geometries.

AI summary
A clamp is configured to securely attach a reel assembly to a fishing rod that is not fitted with a reel seat. The clamp has a first portion that includes a plurality of first flanges and a first concave surface, the first concave surface configured to engage a first side of the fishing rod. The clamp further has at least two second portions each including a plurality of second flanges and a second concave surface, the second concave surface configured to engage a second side of the fishing rod, the second side opposite to the first side. The clamp further has a plurality of fasteners configured to engage the plurality of first flanges and the plurality of second flanges with the first portion positioned on the first side of the fishing rod and the at least two second portions positioned on the second side of the fishing rod.
