Fishing Reel Spool Ring Segmentation for Wear Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing reel spools face issues with scratching, denting, and surface abrasion due to long-term contact with the fishing line, requiring replacement of the entire spool when the spool ring is damaged, leading to high maintenance costs.
Innovation Solution
A spool design with a separable spool ring that can be independently removed and replaced, featuring a fixing ring and regulating parts to securely attach and detach the spool ring from the spool body, allowing for easy maintenance and replacement without needing to remove the entire spool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spool ring is firmly fixed to the flange, then the spool ring provides excellent wear resistance and durability, but the entire spool must be replaced when the spool ring is damaged, leading to high maintenance costs
Solution Approach 1:
The spool ring is separated from the spool body as an independent replaceable component. The spool ring can be detached from the flange and replaced separately without replacing the entire spool, allowing maintenance of only the worn spool ring while reusing the spool body.
Solution Approach 2:
The spool ring is designed as a consumable part that can be discarded when worn and replaced with a new or refurbished spool ring. The spool body is recovered and reused, reducing waste and maintenance costs compared to replacing the entire spool assembly.
2Stability of the object's composition
If the spool ring is firmly fixed to the flange, then the spool ring remains stable during operation, but the spool ring cannot be independently repaired or replaced
Solution Approach 1:
The fixing mechanism transitions from a permanent fixed state to a dynamic state where the spool ring can be easily attached and detached. The fixing ring and regulating parts allow the spool ring to be securely fixed during operation but readily removable when maintenance is needed.
Solution Approach 2:
The fixing system is segmented into separate components (fixing ring, regulating parts) that can be independently manipulated. This allows the spool ring to be securely attached during use but easily separated for replacement without damaging any components.
3Reliability
If a hard material spool ring is used, then wear resistance and friction reduction are improved, but the spool ring is susceptible to scratching and denting from external contact
Solution Approach 1:
The fixing ring and regulating parts are designed to protect the spool ring from external impacts and contact forces. The regulating parts constrain the spool ring's movement and prevent it from contacting external objects that could cause scratching or denting.
Solution Approach 2:
The spool assembly uses a composite structure combining the hard spool ring with the fixing ring and regulating parts. This composite design allows the spool ring to provide wear resistance while the other components provide protection from external damage and enable easy replacement.

AI summary
A spool for a fishing reel attached to a reel body of the fishing reel includes a spool body, a spool ring, a fixing ring and a first regulating part. The spool body has a bobbin trunk, an annular flange extending from the bobbin trunk in a radially outward direction that intersects the spool axis, and a tubular connecting portion extending from the flange. The spool ring surrounds an outer peripheral edge of the flange, and is attached to the flange so as to be separable. The fixing ring is attached to the spool body via the tubular connecting portion so as to be separable and is configured to fix the spool ring against the flange from the front direction. The first regulating part regulates relative movement of the fixing ring with respect to the spool body and is detachably attached to the tubular connecting portion.
