Spinning Reel Guard Member Segmentation for Easy Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spinning reels require complex disassembly to replace guard members, making it difficult to protect the boundary between the rear end surface and outside surface of the coupling portion while allowing for easy replacement.
Innovation Solution
The spinning reel design incorporates removable first and second guard members that cover the boundary between the outside and rear end surfaces of the coupling portion, allowing for separate detachment without removing the rotor from the reel body, with additional guard portions and holding features to prevent displacement and ensure easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional guard member design is used that requires removing the rear cover member and detaching the rotor to replace the guard member, then the boundary between the rear end surface and outside surface of the coupling portion is protected, but the replacement process becomes complex and difficult
Solution Approach 1:
The guard member is divided into multiple independent guard portions (first guard portion, second guard portion, third guard portion, fourth guard portion) that can be detached separately from the rotor body. Each guard portion is secured by its own holding portion, allowing selective replacement of individual guard portions without removing the entire rotor assembly or rear cover member.
Solution Approach 2:
The holding portions are extracted as separate functional elements that can be independently removed from the rotor body. This extraction allows the guard portions to be detached and replaced without affecting the rear cover member or requiring complete disassembly of the rotor assembly.
2Reliability
If the guard member is made as a single integrated component, then the boundary protection is comprehensive, but the replacement process requires complex disassembly of the entire rotor assembly
Solution Approach 1:
The integrated guard member is segmented into multiple independent guard portions, each with its own holding portion for attachment to the rotor body. This segmentation allows individual guard portions to be replaced without disassembling the entire rotor assembly, reducing device complexity during maintenance while maintaining comprehensive boundary protection when all guard portions are installed.
3Ease of repair
If the rear cover member is removed to access and replace the guard member, then the guard member can be replaced, but the maintenance process becomes time-consuming and complex
Solution Approach 1:
The holding portions are extracted as independent attachment mechanisms that allow guard portions to be removed and replaced without removing the rear cover member. This extraction of the attachment function enables direct access to guard portions through the open portion, eliminating the time-consuming step of rear cover member removal while maintaining ease of repair.
Solution Approach 2:
The holding portions are pre-configured on the rotor body to provide ready-made attachment points for guard portions. This preliminary arrangement of attachment mechanisms allows guard portions to be quickly installed or replaced without requiring complex disassembly procedures or removal of the rear cover member, significantly reducing maintenance time.

AI summary
A spinning reel for delivering fishing line has a spinning reel body, a handle, a rotor, and a spool. A rotor body of the rotor has a cylindrical coupling portion, a first rotor arm, and a second rotor arm. A first cover member of the rotor is removably attached to the rotor body covering a radially outer side of the first rotor arm. A first guard member of the rotor is removably attached to the rotor body and has a first guard portion covering a boundary between an outside surface of the coupling portion and a rear end surface of the coupling portion. A second guard member of the rotor is removably attached to the rotor body and has a second guard portion that covers the boundary between the outside surface and the rear end surface at a position opposing the first guard portion.
