Spinning Reel Spool Plastic Deformation Corrosion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spinning reels are prone to corrosion and durability issues due to the formation of closed spaces that can trap foreign substances, and the use of resin components can lead to deformation or breaking under stress.
Innovation Solution
The spinning reel spool design eliminates the need for a spool collar by integrating a plastically deformable protruding portion on the spool body, which holds the ring member in place without forming a closed space, preventing corrosion and reducing stress on resin components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a spool collar (abutting member) is used to hold the ring member, then the ring member can be securely fixed to the spool body, but a closed space is formed that traps foreign substances and causes corrosion
Solution Approach 1:
The invention removes the spool collar (abutting member) from the structure entirely. Instead of using a separate collar component that creates closed spaces, the patent directly integrates the ring member holding function into the spool body through a protruding portion with elastic deformation, eliminating the source of corrosion problems.
Solution Approach 2:
The invention merges the functions of the spool body and the ring member holder into a single integrated structure. The protruding portion on the spool body directly holds the ring member through elastic deformation, combining what were previously separate components (spool body + spool collar) into one unified design that eliminates closed spaces.
2Weight of moving object
If the spool collar is made from resin to reduce weight, then the overall weight of the spool decreases, but the spool collar may deform or break under stress
Solution Approach 1:
The invention removes the spool collar component entirely, eliminating the weight and strength trade-off issue. By directly integrating the holding function into the spool body's protruding portion, the design eliminates the need for a separate resin collar that would be subject to deformation and breaking.
Solution Approach 2:
The invention combines the structural support function into the spool body itself through the protruding portion with elastic deformation capability. This integration eliminates the need for a separate resin collar component, thereby removing the contradiction between weight reduction and strength requirements.
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
This design enhances the durability of the spool by preventing corrosion and maintaining the integrity of resin components, ensuring the spool can withstand exposure to substances like seawater and reduce the risk of deformation.
Implementation Method 1
The ring member is held between the body portion and a plastically deformed part of the protruding portion

AI summary
A spinning reel spool according to a first aspect of the present invention is a spinning reel spool that delivers fishing line forward. The spinning reel spool comprises a spool body and a ring member. This spool body has a body portion and a protruding portion. The protruding portion is integrally formed on a front side of the body portion. The protruding portion is annularly arranged and protrudes from the body portion in an axial direction of the spool body. The ring member is disposed on an outer circumferential portion of the protruding portion of the spool body. The ring member is held between the body portion and a plastically deformed part of the protruding portion.
