Large Arbor Ice Fishing Spool Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ice fishing spools are inefficient for line retrieval and respooling, requiring excessive line and prone to snagging, making the process time-consuming and labor-intensive.
Innovation Solution
A large arbor spool with a cylindrical structure featuring a larger diameter arbor, knot hole, set screw opening, securing hole, and recessed portion, designed to connect to an ice fishing tip-up shaft, reducing the amount of line needed for a full spool and minimizing snagging opportunities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a conventional small arbor spool is used, then the spool can be compact and easy to handle, but the line retrieval speed is slow and respooling is time-consuming
Solution Approach 1:
The patent changes the critical parameter of arbor diameter from small to large. This parameter change directly increases line retrieval speed because a larger arbor allows more line to be wound per rotation, and reduces respooling time by enabling faster line accumulation during retrieval operations
2Quantity of substance
If a conventional small arbor spool is used, then the device structure remains simple, but the amount of line required to fill the spool is excessive
Solution Approach 1:
The patent applies parameter change by increasing the arbor diameter, which exponentially reduces the line capacity needed. A larger arbor circumference means fewer rotations are required to fill the spool, thereby reducing the total line quantity from hundreds of feet to a manageable amount while maintaining structural simplicity
3Object-affected harmful factors
If a conventional small arbor spool is used, then the spool fits standard tip-up shafts, but the line is prone to snagging on submerged objects
Solution Approach 1:
By changing the arbor diameter parameter to a larger size, the patent reduces the total line length required for operation. This directly decreases the portion of line submerged in water, thereby reducing the probability of snagging on underwater obstacles while maintaining compatibility with standard tip-up shafts through appropriate mounting provisions

AI summary
An improved and efficient ice-fishing tip-up spool having a generally cylindrical shape comprising an arbor configured within a first side wall and a second side wall, wherein the arbor has a diameter larger than conventional ice fishing tip-up spools. The larger arbor on the improved and efficient spool decreases the amount of fishing line required to have a full spool which can be achieved with less than 100 feet of fishing line. The large arbor spool also comprises a handle which is integrated onto the second wall and makes the spooling and re-spooling quicker in combination with the larger arbor as the fishing line spooled on per revolution is more than the fishing line spooled on per revolution by conventional ice fishing tip-up spools.
