Spincast Reel Reciprocating Spool Uniform Line Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spincast reels often experience uneven line arrangement and tangling during winding, leading to an enlarged coil diameter and line sticking issues, which affect their usability.
Innovation Solution
A spincast reel design featuring a rotatable main shaft with spiral grooves and a reciprocating reel seat, combined with a braking mechanism, ensures even line winding by using a transmission claw and pin to manage the fishing line, preventing partial tangles and ensuring uniform line arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the spool freely rotates during line withdrawal, then the fishing line can be released smoothly, but uneven line arrangement and partial tangles occur during winding
Solution Approach 1:
The spool is designed to reciprocate along the main shaft axis while rotating, transforming from a purely rotational motion to a combined rotational-reciprocating motion. This dynamic adjustment allows the line pickup portion to systematically guide the fishing line onto different sections of the spool, preventing overlapping and tangling while maintaining smooth line release during withdrawal
Solution Approach 2:
The line pickup portion acts as an intermediary mechanism between the main shaft and the spool. It includes a pin that captures the fishing line and guides it onto the spool surface, ensuring uniform line arrangement. The line pickup portion rotates with the main shaft while the spool reciprocates, creating a coordinated motion that prevents line tangling
2Productivity
If the line pickup portion rotates to wind the fishing line, then the line can be wound onto the spool, but coils may partially stack and enlarge the coil diameter
Solution Approach 1:
The spool's reciprocating motion along the main shaft axis creates a back-and-forth winding pattern. As the line pickup portion rotates to wind the line, the spool moves forward and backward, distributing the coils uniformly across the spool surface. This prevents coil stacking and maintains consistent coil diameter throughout the winding process
Solution Approach 2:
The reciprocating motion of the spool creates a periodic winding pattern where the line is deposited in alternating sections. The spool moves forward, winds line, moves backward, winds line again, creating a systematic periodic action that ensures even line distribution and prevents coil overlap
3Ease of operation
If the fishing line passes through the through hole and gap to reach the spool, then the line can be wound, but the line gets stuck easily affecting use effects
Solution Approach 1:
The line pickup portion with its pin serves as an intermediary that actively captures and guides the fishing line. The pin engages with the line, pulling it smoothly through the gap and onto the spool, preventing the line from getting stuck in the gap or through hole area
Solution Approach 2:
The gap between the line pickup portion and front cover is specifically designed with particular dimensions and positioning. The pin on the line pickup portion is strategically placed to engage the line at an optimal location, creating localized quality improvements that guide the line smoothly through the winding path without sticking

AI summary
A spincast reel includes a frame. A rotatable main shaft is mounted on the frame, the periphery of the main shaft is provided with two spiral grooves with reverse spirals, a side of a shaft sleeve opposite to the spiral groove is provided with a kidney-shaped hole, and a transmission claw which passes through the kidney-shaped hole and is slidably installed in the spiral groove is fixed to a reel seat; one end of the main shaft penetrates into the frame and is provided with a driving gear assembly for driving the main shaft to rotate, and the other end thereof is fixedly connected to a line pickup portion. The spincast reel provides uniform line arrangement and prevents partial fishing line tangles during winding.
