Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fish finders using sound waves to detect fish or underwater structures face challenges when their sound emitter or sound sensor is not submerged, leading to signal degradation and frequent loss of wireless connection due to water attenuation, especially in scenarios like kayaking or canoeing where water levels change.
Innovation Solution
A sensor holder that floats with a bobbing action, maintaining an air pocket above the liquid and automatically adjusting the sensor depth to keep the sonic emitter submerged while keeping the wireless interface above water, ensuring a stable wireless connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the fish finder sensor is submerged in water to detect fish effectively, then detection accuracy is improved, but wireless connection reliability deteriorates due to signal attenuation
Solution Approach 1:
The sensor holder is divided into two distinct sections: an upper section that remains above water to maintain wireless connection, and a lower section that submerges to enable fish detection. This segmentation allows each part to fulfill its specific function in the optimal environment.
Solution Approach 2:
A floatation mechanism acts as an intermediary between the sensor and the water surface, dynamically adjusting the sensor's position to maintain the optimal configuration where the wireless interface stays above water while the sonic transducer remains submerged.
2Reliability
If the wireless interface is kept above water to maintain connection, then wireless connection reliability is improved, but detection accuracy deteriorates because the sound sensor is not submerged
Solution Approach 1:
The sensor holder separates the wireless interface from the sonic transducer vertically, positioning the wireless interface above water for reliable connection while extending the sonic transducer below the surface for effective fish detection.
Solution Approach 2:
The solution transitions from a single-position mounting approach to a vertical dimensional arrangement, where different components are positioned at different depths to optimize their respective functions simultaneously.
3Reliability
If manual adjustment of the fish finder mount is required to maintain wireless connection, then wireless connection reliability is improved, but ease of operation deteriorates due to frequent adjustments
Solution Approach 1:
The floatation mechanism automatically adjusts the sensor holder's position in response to changing water levels, eliminating the need for manual intervention. The system self-regulates to maintain the optimal configuration where the wireless interface remains above water while the sensor stays submerged.
Solution Approach 2:
The floatation mechanism provides continuous feedback through buoyancy forces, automatically compensating for water level changes and maintaining the optimal sensor position without user intervention.
4Device complexity
If the sensor holder is fixed in position, then device complexity is reduced, but adaptability deteriorates when water levels change
Solution Approach 1:
The sensor holder transitions from a fixed rigid structure to a dynamic floating structure that can vertically move in response to water level changes, maintaining optimal sensor positioning across varying conditions.
Solution Approach 2:
The system allows the vertical position parameter of the sensor holder to change dynamically with water levels, while maintaining the functional relationship between sensor depth and wireless interface elevation.

AI summary
Apparatus and associated methods relate to a sensor holder adapted to float with a bobbing action when partially submerged in a liquid, while maintaining an air pocket within a first open holder end above the liquid, and removably retaining an electronic sensor in a liquid tight compartment disposed within a second holder end submerged in the liquid. In an illustrative example, the holder may be a substantially conical funnel. The open holder end may be, for example, open to the atmosphere, permitting wireless connection with the electronic sensor. In some examples, the holder may slidably retain a float rod adapted to allow the liquid to freely and vertically displace the holder as the liquid level varies. Various examples may advantageously provide automatic adjustment of the holder position to preserve a wireless connection with a retained electronic fishing sensor, maintaining the air pocket above the sensor as the liquid level varies.
