Motorized Sonar Mount with Decoupling Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sonar systems for anglers require manual attention to adjust the transducer orientation, which diverts attention from fishing and do not allow quick depth adjustments or protection from submerged objects, leading to potential damage and high replacement costs.
Innovation Solution
A motorized mount assembly with a stepper motor and control module that allows selective rotation of the sonar transducer, featuring an elongated shaft and a connector system that can rotate independently if an obstruction is encountered, enabling automatic adjustment and protection from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual control system with pedals is used to rotate the transducer, then the angler can control the transducer orientation, but the angler's attention is diverted from fishing
Solution Approach 1:
The system uses a motorized mount with a stepper motor that automatically adjusts the transducer orientation and depth based on pre-programmed sequences or user-selected modes, eliminating the need for continuous manual pedal operation while maintaining control capability
Solution Approach 2:
The mount assembly incorporates a motorized mechanism that dynamically adjusts the transducer position and orientation automatically, transitioning from static manual control to dynamic automated control while preserving user oversight through programmable options
2Productivity
If the transducer is fixed at a set depth, then the mounting structure is simple, but the transducer cannot be quickly adjusted to different depths
Solution Approach 1:
The mount assembly incorporates a motorized mechanism with a threaded rod and nut assembly that enables dynamic depth adjustment of the transducer, allowing quick transition between different depths while maintaining a relatively compact integrated structure
Solution Approach 2:
The motorized mount serves multiple functions: it provides both rotational orientation control and vertical depth adjustment capabilities in a single integrated assembly, reducing the need for separate adjustment mechanisms
3Reliability
If the transducer is rigidly connected to the mount, then the structure is stable, but the transducer can be damaged by submerged objects
Solution Approach 1:
The connector incorporates a spring-loaded or flexible coupling mechanism that allows the transducer to move independently upon encountering resistance from submerged objects, preventing force transmission that could damage the transducer while maintaining normal stable operation
Solution Approach 2:
The connection between the shaft and transducer uses a flexible or decoupled interface that permits relative movement when obstructions are encountered, transitioning from a rigid stable connection to a dynamically adaptable connection that protects against damage
4Measurement precision
If the shaft is rigidly connected to the stepper motor output, then the rotation control is precise, but the system cannot accommodate obstructions that prevent rotation
Solution Approach 1:
The connector includes a flexible coupling or disengageable mechanism that allows the shaft to rotate independently from the motor output when obstructions are encountered, protecting the motor and control system from damage while maintaining precise control during normal operation
Solution Approach 2:
The connection system is divided into separable components with a flexible interface between the motor output and the shaft, allowing independent rotation of the shaft when needed while maintaining precise motor control during normal operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables hands-free operation of the sonar transducer, allowing anglers to focus on fishing while automatically adjusting the transducer depth and preventing damage from submerged objects, reducing the need for frequent replacements.
Implementation Method 1
A stepper motor positioned inside the hollow interior of the housing has an output that rotates relative to the housing in response to an input signal
Implementation Method 2
The connector is configured to allow the output of the stepper motor to rotate independently from the elongated shaft when an obstruction prevents the elongated shaft from turning about the central axis

AI summary
A mount assembly for connecting a sonar transducer to a boat. The assembly includes a bracket, a housing, and a stepper motor having an output that rotates in response to a signal. A control module connected to the motor sends the input signal to the motor. The assembly includes a shaft having an upper end, a lower end, and a central axis. The upper end is connected to the output for rotation when the control module sends the signal to the motor. The shaft is adapted to mount a sonar transducer adjacent to the lower end. The assembly comprises a connector operationally connecting the shaft to the output of the motor, so the shaft rotates as the output rotates. The connector is configured to allow the output of the motor to rotate independently from the shaft when an obstruction prevents the shaft from turning.
