Fishing Reel Motor Power Unit Segmentation and Magnetic Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing reels, particularly electric reels, can be difficult to operate when a big fish is caught, as users struggle to manage the push button with one hand, leading to challenges in adjusting winding speed and overall operability.
Innovation Solution
A fishing reel design featuring a motor power unit with a detachable coupling mechanism and an external operation unit, such as a throttle lever, dial, or push switch, allowing for adjustable driving force and remote control, enabling easy operation from a desired position, including on a rod, wrist, or floor, and facilitating switching between manual and electric modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation unit (push button) is integrated into the reel body, then the structure is compact, but the ease of operation deteriorates when the user's hands are occupied
Solution Approach 1:
The operation unit is separated from the reel body and can be independently positioned at desired locations such as on the rod or wrist, allowing operation without occupying the user's hands while maintaining structural integrity
Solution Approach 2:
A magnetic coupling mechanism acts as an intermediary between the operation unit and the reel body, enabling flexible positioning and easy attachment/detachment while maintaining operational control
2Ease of operation
If the motor power unit is built-in the reel body, then the structure is integrated, but the ease of operation and accessibility deteriorate
Solution Approach 1:
The motor power unit is separated from the reel body and can be independently positioned or removed, allowing flexible operation and adaptation to different fishing scenarios while maintaining system functionality
Solution Approach 2:
The motor power unit can be dynamically attached or detached from the reel body based on operational needs, enabling switching between manual and electric modes and adapting to different user requirements
3Ease of repair
If the coupling mechanism is permanent, then the structure is stable, but the ease of repair and part replacement deteriorate
Solution Approach 1:
A magnetic coupling mechanism serves as an intermediary connection between parts, providing both stable operation during use and easy separation for repair or replacement, balancing reliability with maintainability
Solution Approach 2:
The coupling mechanism transitions from a static permanent connection to a dynamic magnetically-coupled connection that can be easily engaged or disengaged, facilitating repair while maintaining operational stability
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
Enhances operability by allowing users to easily adjust the reel's driving force and switch between manual and electric modes, improving usability and flexibility during fishing, especially when dealing with large fish, and enabling efficient line winding and line replacement.
Implementation Method 1
a magnet is disposed on one of the coupling part and the coupling counterpart, and a magnet or a ferromagnetic material is disposed on other thereof

AI summary
A fishing reel includes: a reel body; a spool supported by the reel body so as to be rotatable; a handle attached to the reel body so as to be rotatable; a first rotation transmission mechanism that transmits, to the spool, a driving force due to rotation of the handle; a motor power unit that generates a driving force that rotates the spool; a second rotation transmission mechanism that transmits the driving force of the motor power unit to the spool; and an operation unit that is disposed outside the reel body and changes the driving force of the motor power unit, wherein the operation unit is configured to be set at a position desired by a user so as to be usable.
