Fishing Electric Reel Clutch Return Mechanism for Compact Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing electric reels with electric motors face challenges in securing a wide slide space for components, leading to reduced layout freedom and increased reel body size due to the linear sliding movement of the slide plate and direct abutment of the abutment piece on the protrusion portion of the returning gear.
Innovation Solution
The fishing electric reel incorporates a clutch mechanism with a clutch operating member that rotates to switch between states, a return mechanism using a returning gear and a kick member supported by the frame, and a handle operation return mechanism with a ratchet, allowing for high space efficiency and preventing an increase in reel body size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the slide plate linearly slides from the clutch-on position to the clutch-off position with direct abutment of the abutment piece on the protrusion portion of the returning gear, then the clutch mechanism can be switched between driving force transmission state and driving force interruption state, but it requires a wide slide space of the slide plate in the frame of the reel body, which lowers the degree of freedom of the layout of the components and increases the reel body size
Solution Approach 1:
The patent changes the linear sliding movement of the slide plate to a rotational movement of the clutch operating member. The kick member rotates to engage with and disengage from the returning gear, utilizing rotational dimension instead of linear sliding dimension. This dimensional change allows the mechanism to function within a smaller spatial footprint, reducing the overall reel body size while maintaining the clutch switching function.
Solution Approach 2:
The clutch operating member and kick member are disposed between the spool shaft and the motor shaft, nesting the clutch mechanism within the existing structural space of the reel. This nested arrangement allows the clutch switching mechanism to occupy minimal additional space, preventing reel body enlargement while enabling full clutch functionality.
2Ease of operation
If the slide plate linearly slides with wide slide space, then the clutch mechanism can be operated, but the degree of freedom of the layout of the components is lowered due to the presence of more components in fishing electric reel
Solution Approach 1:
By transitioning from linear sliding to rotational movement, the patent frees up linear space within the frame, allowing components to be arranged more flexibly in three-dimensional space. The rotational clutch operating member can be positioned compactly between the spool shaft and motor shaft, giving designers greater freedom to optimize the layout of other components without being constrained by a large linear slide space.

Function Achieved in This Case
This configuration enhances component layout freedom, prevents reel body enlargement, and ensures quick responsiveness and ease of use with reduced need for additional sensors, resulting in a cost-effective and operable fishing electric reel.
Implementation Method 1
when the electric motor is reversely rotated in the driving force interruption state, the protrusion portion of the clutch returning gear abuts on the abutment piece of the slide plate
Implementation Method 2
a kick member that is rotatably supported by the clutch operating member, rotates in conjunction with rotation of the clutch operating member to engage with/disengage from the clutch returning rotator

AI summary
A clutch mechanism has a clutch operating member that is rotated by an operation of a clutch lever and is brought into a driving force interruption state. A return mechanism causes the clutch mechanism that has been brought into the driving force interruption state to return to a driving force transmission state. The return mechanism comprises a returning gear that is provided on a motor shaft of an electric motor, a clutch returning rotator that meshes with the returning gear and rotates, and a kick member that is rotatably supported by the clutch operating member, rotates in conjunction with rotation of the clutch operating member to engage with/disengage from the clutch returning rotator, and causes the clutch operating member that has been brought into the driving force interruption state to return to the driving force transmission state. The clutch returning rotator and the kick member are disposed between a spool shaft and the motor shaft.
