Resilient Grip for Fishing Rod Triggers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Casting type fishing rods with hard plastic triggers cause discomfort and pain due to constant pressure on hands and fingers, and they often result in slippage during fishing activities.
Innovation Solution
A soft rubber grip with a resilient, moldable design that conforms to the trigger shape, featuring a smaller inner wall and varying external features, and optionally a retaining band with flexible ribs to secure the grip without adhesives, providing a comfortable and non-slip surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a hard plastic trigger is used to provide structural support and leverage, then the rod can withstand casting forces, but the user experiences hand and finger pain and discomfort
Solution Approach 1:
The patent applies a flexible rubber grip shell over the hard plastic trigger, creating a soft interface between the user's fingers and the rigid trigger structure. This flexible shell conforms to the trigger shape while providing cushioning, thus maintaining structural support through the rigid inner trigger while eliminating pain through the compliant outer grip layer.
Solution Approach 2:
The solution combines two different materials with complementary properties: a hard plastic inner trigger for structural strength and a soft rubber outer grip for comfort. This composite structure allows each material to perform its optimal function - the plastic provides leverage and casting strength while the rubber provides comfort and slip resistance.
2Force
If a hard plastic trigger is used to maintain grip during casting, then leverage is provided, but slippage occurs between fingers and trigger surface
Solution Approach 1:
The flexible rubber grip shell conforms to the contours of the hard plastic trigger, creating maximum surface contact area. This conformal contact increases friction and prevents slippage while allowing the rigid inner trigger to maintain its leverage function during casting and fighting fish.
Solution Approach 2:
The rubber grip provides localized tackiness and friction enhancement only at the finger contact surfaces, while the inner plastic trigger maintains its hard structural properties for leverage. This local differentiation allows the grip surface to prevent slippage without compromising the overall mechanical advantage.
3Ease of operation
If a soft rubber grip is added to reduce pain and slippage, then comfort and grip stability improve, but the device complexity increases
Solution Approach 1:
The rubber grip is designed as a nested component that fits over the existing hard plastic trigger, much like a doll within a doll. This nested structure allows the comfort-enhancing rubber layer to be added without replacing the entire trigger assembly, thus improving ease of operation while minimizing the increase in overall device complexity.
Solution Approach 2:
The rubber grip serves multiple functions simultaneously: it provides pain relief through cushioning, prevents slippage through increased friction, and maintains structural integrity by conforming to the trigger shape. This multi-functionality in a single component reduces the need for additional separate elements, thereby limiting the increase in device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The grip reduces hand and finger strain, minimizes slippage, and accommodates various trigger shapes and sizes, offering a comfortable and secure hold during fishing activities.
Implementation Method 1
The soft, resilient quality of the grip allows the grip to 'receive' and conform to the trigger of the casting rod
Implementation Method 2
the grip also provides a mechanism to improve the grasp and reduce slippage by providing a tacky surface to the trigger

AI summary
A resiliently flexible grip for fishing rods has a hollow tubular main body and includes a retaining band that wraps around the fishing rod, which keeps the flexible grip fixed to a trigger of a fishing rod. The main body conforms to any shape of the trigger and compresses uniformly to provide a custom fit on the trigger. The grip, during use, compresses and conforms to the individual user's finger and hands providing comfort while fishing.
