Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing reels inaccurately calculate unwinding distance due to variations in fishing line attributes, leading to ineffective casting and waiting, especially in sea fishing without a reference object.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If a digital display fishing reel with unwinding length calculation function is used, then casting distance measurement capability is improved, but calculation accuracy deteriorates due to variations in fishing line attributes
Solution Approach 1:
The patent applies parameter changes by pre-storing multiple winding density parameters corresponding to different fishing line specifications (diameter, material, construction) in a database. When a user selects their fishing line type, the system retrieves and applies the specific winding density parameter for that line type, thereby adapting the calculation to the actual line characteristics and improving measurement precision while maintaining the ability to measure casting distance.
2Adaptability or versatility
If different fishing lines with different wire attributes are wound on the same spool, then fishing line versatility is improved, but unwinding length calculation accuracy deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-conducting winding experiments with various fishing line specifications and storing the resulting winding density parameters in a database before actual fishing use. This pre-characterization of different line types allows the system to quickly select the appropriate parameter when a user inputs their line type, enabling accurate calculations for diverse fishing lines without requiring real-time measurement or calibration.
3Device complexity
If unwinding length is calculated based solely on spool dimensions and circle count, then device complexity is reduced, but calculation accuracy deteriorates
Solution Approach 1:
The patent introduces an intermediary element - a pre-conducted winding experiment database that stores the relationship between fishing line specifications and actual winding density. This intermediary database acts as a bridge between the simple mechanical measurement (spool dimensions and circle count) and the accurate calculation of unwinding length, allowing the system to maintain computational simplicity while achieving high precision by looking up empirically determined parameters.

AI summary
Disclosed are a fishing data calculation method, a mobile terminal, and a fishing reel system. The method includes: pre-constructing a winding database of different fishing lines wound to a spool of a fishing reel; acquiring a current winding length of a current fishing line on the spool; acquiring a current number of circles of unwinding of the spool during casting; and calculating a current unwinding length corresponding to the current number of circles of unwinding according to the winding database and the current winding length. In the disclosure, the winding database of the different fishing lines wound to the spool of the fishing reel is pre-constructed, and the unwinding length of the fishing line on the spool is calculated by an algorithm based on the fishing line selected by a user when the user performs fishing, thereby having the advantage of improving the calculation accuracy of the unwinding length.
