Fishing Reel Line Clip Buffer Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing reel line clip devices either deform and damage the fishing line due to increased spring force or fail to reliably clip the line, especially when used as a 'point memory' under drastic load conditions.
Innovation Solution
A fishing reel with a line clip device featuring a metal fishline clipping member, a buffer member made of a hard resin, and a spring member that elastically supports the clipping mechanism, allowing the line to be clipped between the buffer and the constructional element, with a concave portion for secure clipping and a space for load reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spring force of the spring member is increased to improve the clipping reliability, then the fishline clipping reliability is improved, but the fishline is deformed and damaged
Solution Approach 1:
The patent introduces a buffer member as an intermediary component between the spring member and the fishline. This buffer member absorbs and distributes the spring force, preventing direct concentration of force on the fishline while maintaining effective clipping pressure. The buffer member acts as a mediator that reconciles the need for strong clipping force with the need to protect the fishline from damage.
Solution Approach 2:
The patent changes the physical parameters of the clipping system by introducing a buffer member with specific material properties (elastic modulus, density) that differ from both the spring member and the fishline. This parameter change allows the system to maintain high clipping force while distributing the stress to prevent fishline deformation and damage.
2Adaptability or versatility
If the line clip device is used as a point memory under drastic load conditions, then the fishline can be held at a specific position, but the line holder may be damaged and the fishline may be cut
Solution Approach 1:
The patent applies beforehand cushioning by pre-installing a buffer member between the line holder components and the fishline. This buffer member is designed to absorb drastic loads before they can damage the line holder or cut the fishline. The cushioning effect is prepared in advance, allowing the system to withstand point memory operations under heavy load conditions.
Solution Approach 2:
The buffer member serves as an intermediary that protects both the line holder structure and the fishline from direct contact under drastic load conditions. It absorbs the shock and distributes the stress, preventing damage to the line holder and avoiding cutting of the fishline during point memory operations.
3Ease of operation
If the rubber fishline clipping member is used to enable easy clipping, then the ease of operation is improved, but the clipping reliability deteriorates due to easy deformation
Solution Approach 1:
The patent employs composite materials strategy by combining a metal fishline clipping member with a resin buffer member. The metal clipping member provides structural strength and shape retention for reliable clipping, while the resin buffer member provides elasticity and compliance for ease of operation. This composite structure integrates the advantages of both materials to achieve both easy operation and high reliability.
Solution Approach 2:
The patent applies local quality by assigning different material properties to different parts of the clipping system. The fishline clipping member is made of metal with high strength and shape retention for reliable clipping, while the buffer member is made of resin with elastic properties for ease of operation. Each component has optimized local material properties suited to its specific function.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures the fishing line is securely clipped without damage, even under severe conditions, and prevents the clip from being damaged or cut when used as a 'point memory', with the metal clipping member providing durability and the resin buffer offering protection and flexibility.
Implementation Method 1
a spring member for preventing the stem portion from slipping off the through hole and elastically supporting the stem portion
Implementation Method 2
a buffer member for reducing the spring force of the spring member; and wherein the fishline is to be clipped between the buffer member and the constructional element

AI summary
A fishing reel (107,127) includes: a constructional element (61,121) including a through hole (73) formed through a predetermined part thereof; a fishline clipping member (75) including a fishline clipping portion (77) and a stem portion (79) inserted into the through hole; a spring member (83) for preventing the stem portion from slipping off the through hole and elastically supporting the stem portion; and a buffer member (87) mounted between the constructional element (61) and the fishline clipping portion (77). The fishline clipping portion cooperates with the constructional element and the buffer member for elastically clipping a fishline (103).
