Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Anglers face challenges in determining the operating depth and wobble of fishing lures, leading to inefficiencies in fishing due to external observation errors such as parallax and refraction, and there is a need for real-time environmental data to enhance fishing success.
Innovation Solution
A castable sensor device equipped with environmental sensors, including pressure, chlorophyll, oxygen, temperature, light, and acidity sensors, attached to a fishing line or lure, which transmits data to a marine electronic device for display on a user interface, providing depth and wobble profiles, and allowing for dynamic adjustments to improve fishing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external observation methods are used to determine lure depth and wobble, then the observation process is simple, but measurement precision deteriorates due to parallax and refraction errors
Solution Approach 1:
The patent replaces the mechanical/visual observation system with an electronic sensor system. Sensors embedded in the lure body electronically measure depth (via pressure sensor) and wobble (via accelerometer and gyroscope), substituting the human visual observation system that suffers from parallax and refraction errors.
Solution Approach 2:
The patent introduces sensors as intermediary devices between the lure's motion and the measurement process. These sensors act as mediators that directly detect physical quantities (pressure, acceleration, orientation) without requiring external visual observation, thereby eliminating observation errors.
2Device complexity
If no real-time data is provided, then the device complexity is low, but loss of information increases as anglers cannot verify lure performance
Solution Approach 1:
The patent implements a feedback system where sensors continuously monitor lure depth and wobble, transmit this data to a processing system, and provide real-time feedback to the angler. This closed-loop feedback eliminates information loss by making lure performance data available for verification and adjustment.
Solution Approach 2:
The patent creates a multi-functional device that not only serves as a fishing lure but also incorporates sensing, data processing, and communication functions. This universal device combines lure functionality with measurement and data transmission capabilities, reducing information loss without requiring separate equipment.
3Measurement precision
If multiple environmental sensors are added to the lure, then measurement precision of environmental conditions improves, but device complexity increases
Solution Approach 1:
The patent merges multiple sensing functions (pressure, acceleration, orientation, temperature, light, chlorophyll, oxygen, acidity) into a single integrated lure device. By combining these sensors within the lure body and consolidating their data processing, the system achieves high measurement precision while managing device complexity through integration.
Solution Approach 2:
The lure is designed as a universal platform that performs both fishing functions and environmental monitoring functions. The same lure structure houses multiple sensors that measure various environmental parameters, creating a multi-functional device that gains measurement precision without requiring separate specialized equipment for each parameter.

Function Achieved in This Case
The castable sensor device provides accurate real-time data on environmental conditions, enabling anglers to adjust lure depth and wobble, increasing the likelihood of successful fishing by correlating sensor data with fish profiles and recommending corrective actions.
Implementation Method 1
one or more environmental sensors may be attached to a fishing line and casted in a body of water to detect various environmental conditions
Implementation Method 2
The castable sensor device may include the one or more environmental sensors and may be used in either saltwater and/or freshwater
Data Source
AI summary
A sensor assembly for a castable lure is provided including a pressure sensor configured to measure a water pressure applied to the castable lure when deployed in an underwater environment, a processor, and a memory including computer program code. The computer program code configured to, when executed on the processor, cause the processor to receive pressure data from the pressure sensor, correlate the pressure data with time stamp data, cause the pressure data and correlated time stamp data to be stored in the memory, determine a data connection status between a transceiver and a marine electronic device, and in response to determining that a data connection exists, cause the pressure data and the correlated time stamp data to be transmitted to the marine electronic device. The pressure data and correlated pressure data correspond to a depth profile for a cast of the castable lure.
