Sinking Measuring Unit for Watercourse Profile Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining water profiles, such as buoys and underwater vehicles, are limited in accuracy and require additional equipment, making them costly and impractical for anglers.
Innovation Solution
A method and device where a measuring unit sinks to the bottom of a water body, is dragged along the bottom to collect data, and is synchronized with an evaluation program for precise data acquisition and display, using a positioning device like a fishing rod, without additional equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If buoys are deployed to measure water depth, then depth measurement is possible, but the exact position on the water cannot be determined and additional equipment is required
Solution Approach 1:
The measuring unit is designed to be self-positioning by sinking to the bottom and using its own weight and the positioning device (fishing rod) to automatically locate itself at the desired measurement position without requiring additional positioning equipment or manual adjustment
Solution Approach 2:
The patent extracts the positioning function from complex external equipment and integrates it into the measuring unit itself through the sinking mechanism and fishing rod positioning, eliminating the need for separate positioning systems
2Loss of information
If remotely controlled underwater vehicles are used, then comprehensive measurement data can be collected, but the system becomes complex and costly
Solution Approach 1:
The patent extracts only the essential measurement function (depth measurement) from complex underwater vehicles and implements it in a simple measuring unit that sinks and is dragged along the bottom, collecting data at intervals without requiring complex navigation or control systems
Solution Approach 2:
Instead of using a complex vehicle that can perform multiple functions, the patent uses a simple measuring unit that performs only the essential depth measurement function, collecting sufficient data at regular intervals along the path without attempting to capture all possible parameters
3Measurement precision
If depth sounders are used in boats, then depth measurement is possible, but the water profile cannot be accurately mapped and additional equipment is required
Solution Approach 1:
The patent transitions from static depth measurement (boat-based sounders) to dynamic measurement by dragging the measuring unit along the bottom, collecting multiple depth readings at different positions to create a profile, using the fishing rod as a dynamic positioning and measurement system
Solution Approach 2:
The measuring unit automatically positions itself at the bottom and collects data at regular intervals along its path without requiring external guidance or complex control systems, with the fishing rod serving as both positioning and measurement device

AI summary
The invention relates to a method for determining a watercourse profile with at least one measuring unit for acquiring measurement data. The method is characterized in that the measuring unit is moved to a specific position in the watercourse by means of a positioning device, that the measuring unit sinks to the bottom of the watercourse at that position, that the measuring unit is moved across the bottom of the watercourse after reaching it, in particular by dragging it across the bottom of the watercourse, that the measurement data are acquired while the measuring unit is moved across the bottom of the watercourse, and that the watercourse profile is created using the measurement data.
