Fishing Line Cutter With Nested Guides And Pivot Blade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing line cutters are inefficient, difficult to use, and cumbersome, particularly when attempting to cut lines attached to protected species like dolphins or turtles, often leading to entanglement and harm.
Innovation Solution
A fishing line cutter with an oval-shaped side plate, line guides, spacers, an anvil, and a pivotable actuator lever with a cutting blade, allowing for precise cutting of the line near the hook without disassembling the cutter or cutting the line during insertion, facilitated by a tag line mechanism for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing fishing line cutters are used, then the cutting function is provided, but the device is inefficient, difficult to use, and cumbersome
Solution Approach 1:
The device is divided into separate functional modules: a cutter assembly with cutting blade and anvil, a line guide assembly with multiple guides, and a handle assembly. This segmentation allows each component to be optimized independently and makes the overall device easier to operate and maintain while reducing complexity through modular design.
Solution Approach 2:
The cutting blade is made movable relative to the anvil through a pivot mechanism, allowing the blade to be positioned for cutting and then retracted or adjusted. This dynamic positioning enables precise cutting control and reduces the complexity of fixed multi-component designs by using a single movable cutting assembly.
2Length of moving object
If the fishing line cutter is designed to cut close to the hook, then the line length is reduced, but the device must be more precise and controlled
Solution Approach 1:
The line guide assembly positions the fishing line through multiple guides before the cutting point, pre-aligning the line with the cutting blade. This preliminary positioning ensures that when the blade cuts, it does so precisely at the intended location close to the hook, achieving both short line length and high cutting precision without requiring complex adjustment mechanisms during the cutting action itself.
3Ease of operation
If the cutter allows line insertion without disassembly, then the operation is simplified, but the device structure must be more complex
Solution Approach 1:
The line guide assembly is designed with nested guides that allow the fishing line to be inserted through multiple guides in sequence without disassembling the entire device. The guides are arranged concentrically or in sequence within the handle assembly, enabling simple line insertion while maintaining a compact, less complex overall structure compared to devices requiring disassembly.
4Object-affected harmful factors
If the cutting blade is positioned to cut near the hook, then the entanglement risk is reduced, but the device must be more stable and controlled
Solution Approach 1:
The anvil serves as an intermediary element between the movable cutting blade and the fishing line. The blade cuts the line against the anvil, which provides a stable, fixed reference point. This intermediary mechanism allows the blade to be positioned close to the hook for cutting while the anvil maintains device stability and control during the cutting operation, preventing entanglement.
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
Enables efficient and safe cutting of fishing lines close to the hook, reducing the risk of entanglement and ensuring a short line length is left attached, making the process easier, more refined, and durable.
Implementation Method 1
the cutting blade will pass beneath the anvil as it is moved from its first position towards the second position
Implementation Method 2
An actuator lever, having upper and lower ends, is also provided with the actuator lever having a cutting blade secured to the upper end thereof. The actuator lever is pivotally secured, intermediate its upper and lower ends, to the first side plate
