Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cable steer configuration is used, then tactile feedback is provided to the user, but automated electronic steering functionality is lost
Solution Approach 1:
The patent combines mechanical cable steering and electronic fly-by-wire steering into a single integrated system. The pedal assembly is mechanically linked to the trolling motor assembly via cables while simultaneously being electrically connected to a control system, allowing both tactile feedback and automated electronic steering functions to operate together in the same system.
Solution Approach 2:
The pedal assembly serves multiple functions: it provides mechanical input through cable tension for tactile feedback, generates electrical signals for electronic control, and can operate in both manual and automated modes. This multi-functionality allows the same control interface to support both traditional cable steer characteristics and modern electronic steering capabilities.
2Ease of operation
If a cable steer system is used, then mechanical linkage provides feedback, but excessive actuation force is required to counteract torque steer
Solution Approach 1:
The patent introduces an electronic control system as an intermediary between the pedal and the trolling motor assembly. Electrical signals transmitted from the pedal to the control system enable electronic assistance that reduces the mechanical force required at the pedal, while the mechanical cable linkage continues to provide tactile feedback.
Solution Approach 2:
The patent replaces portions of the purely mechanical cable steer system with an electronic control system. Electrical signals and electronic actuators substitute for some mechanical force transmission, reducing the actuation force needed at the pedal while maintaining mechanical feedback through the retained cable linkage.
3Extent of automation
If an electronic steer configuration is used, then automated steering functions are enabled, but tactile feedback is lost
Solution Approach 1:
The patent merges electronic fly-by-wire steering with mechanical cable feedback. The system integrates electrical signal transmission for automated control with physical cable connections that transmit tactile feedback from the motor assembly to the pedal, combining the advantages of both electronic and mechanical steering systems.
4Ease of operation
If a purely mechanical cable steer system is used, then tactile feedback is maintained, but automated navigational functionality is unavailable
Solution Approach 1:
The pedal assembly is designed to serve multiple functions simultaneously: it provides mechanical input through cable tension for tactile feedback, generates electrical signals for electronic control systems, and supports both manual and automated operational modes. This multi-functionality enables the same control interface to deliver both traditional cable steer characteristics and modern electronic navigational capabilities.
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
The system offers the tactile feedback of cable steer systems while enabling automated electronic steering, reducing the need for excessive pedal force and mitigating torque steer issues, allowing for precise control and navigation assistance.
Implementation Method 1
A motor is provided and mechanically coupled to the drive train such that the motor applies an input torque to the trolling motor assembly to rotate the trolling motor assembly about a longitudinal axis of the trolling motor assembly.
Implementation Method 2
A cable drum is provided and rotatable with the steer tube. At least one cable is connected between the pedal assembly and the cable drum such that a rotation of the pedal about the pedal axis causes a rotation of the cable drum.
Data Source
AI summary
