Integrated Click Spring Washer for Fishing Reel Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing reels with clicking sound generating mechanisms face issues of complex construction, low assemblability, high defect rates, and cost inefficiency, leading to difficulties in assembly and maintenance.
Innovation Solution
A fishing reel design utilizing various washers to create a clicking sound generating mechanism with a click member and spring contact parts, where the click spring is integrated with an auxiliary washer by cutting and bending, allowing for easy assembly and minimizing part changes, while providing a rhythmical clicking sound and a pre-existing brake function to prevent line damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional clicking sound generating mechanism is used, then a clicking sound is generated, but the construction becomes complicated and assemblability decreases
Solution Approach 1:
The patent combines the click spring and click plate into a single integrated component, eliminating the need for separate assembly. The click spring is formed as one piece with the click plate, reducing the number of parts and simplifying the overall construction while maintaining the clicking sound generation function.
Solution Approach 2:
The integrated click spring-click plate structure serves multiple functions simultaneously: it provides the elastic force for clicking, acts as the contact surface for sound generation, and eliminates the need for separate mounting structures. This multi-functionality reduces construction complexity while ensuring reliable clicking sound generation.
2Reliability
If a complex clicking sound generating mechanism is used, then clicking sound is generated, but productivity decreases and defect rate increases
Solution Approach 1:
By merging the click spring and click plate into one integrated component, the patent reduces the number of assembly steps and minimizes the risk of assembly defects. This single-component approach significantly improves productivity while maintaining reliable clicking sound generation.
3Ease of manufacture
If existing washers are used to create the clicking mechanism, then cost is reduced, but the structure must be modified
Solution Approach 1:
The patent segments the washer structure by cutting a specific portion of the washer to create the click spring shape. This segmentation allows the use of standard washer components while achieving the specialized click spring function, balancing cost-effectiveness with functional requirements.
Solution Approach 2:
The patent modifies the washer by changing its geometric parameters through cutting and bending operations. By adjusting the shape and dimensions of the washer after manufacturing, the patent creates the necessary click spring functionality without requiring entirely new component designs, thus controlling manufacturing costs.

AI summary
A fishing reel includes a central shaft, a drive gear coupled to the central shaft, a spool connected to the drive gear and winding a fishing line thereon, a drive washer mounted to the central shaft to interlock with the central shaft, an auxiliary washer mounted to the central shaft and having a projection to interlock with the drive gear, and a clicking sound generator. The clicking sound generator includes a click member operated in conjunction with the central shaft or the drive gear and having a spring contact part, and a click spring operated in conjunction with the drive gear or the central shaft and having a protruding part coming into contact with the spring contact part, and an elastic part integrated with the protruding part to put the protruding part in contact with the spring contact part.
