Wireless Fishing Reel Depth Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional small fishing reels used for jigging lack a display unit to measure and display terminal tackle water depth, hindering the ability to ascertain water depth and complicating jigging movements due to the need for external cord connections.
Innovation Solution
A fishing reel with a built-in water depth measurement unit that wirelessly transmits data to an external display device, eliminating the need for a connecting cord and allowing for a compact reel design, using UWB or Bluetooth for communication and a synthetic resin case to prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display unit is arranged on the reel unit to display water depth data, then the water depth of terminal tackle can be ascertained, but the reel size increases and complicates the structure
Solution Approach 1:
The system is divided into two independent parts: a compact fishing reel that performs water depth measurement, and a separate display device that shows the data. This segmentation allows the reel to remain small while still providing water depth information through wireless transmission.
Solution Approach 2:
A wireless communication intermediary (transmitter in reel, receiver in display device) is introduced to transfer water depth data between the reel and display device without physical connection. This eliminates the need for a cord while enabling data transmission.
2Loss of information
If a cord connects the display unit and reel to transmit water depth data, then data can be displayed externally, but the cord becomes an impediment during jigging operations
Solution Approach 1:
The mechanical connection (cord) is replaced with a wireless communication system using electromagnetic waves for data transmission. This substitution eliminates the physical cord that interferes with jigging movements while maintaining data transmission capability.
3Ease of operation
If the reel is designed without a display unit to maintain small size, then jigging can be easily performed, but the water depth of terminal tackle cannot be ascertained
Solution Approach 1:
The display function is extracted from the reel and placed in a separate display device. The reel retains only the essential fishing functions plus water depth measurement, while the display capability is taken out to an external device connected via wireless communication.
4Measurement precision
If a display unit with water depth measurement is integrated into the reel, then water depth can be displayed, but the reel structure becomes complex and large
Solution Approach 1:
The system segments the measurement and display functions into separate units. The reel contains only the water depth measurement unit and transmitter, while the display device contains the receiver and display unit, reducing complexity in each individual component.

AI summary
A fishing reel 100 includes a data communication unit 44 capable of wirelessly transmitting terminal tackle water depth data to a data communication unit 66 of a fishing data display device 60, which is arranged outside of a fishing reel 100. The fishing data display device 60 includes a display unit 65 that displays the terminal tackle water depth data obtained from the data communication unit 44 and fish depth data obtained from a data communication unit 91 of a fish finder 90. The fisherman is capable of easily performing jigging with a fishing reel, as well as ascertaining the water depth of terminal tackle.
