Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional boat steering and propulsion systems require complex mechanical setups and often limit the operator's ability to control both propulsion and steering efficiently, particularly in small watercraft like kayaks, where manual adjustments can be cumbersome and less precise.
Innovation Solution
A foot-actuated steering and propulsion system utilizing rotatable motors and motion sensors that allow boat operators to control the angle and thrust of a propeller using pedals or foot-worn sensors, enabling independent control of each foot to execute precise maneuvers such as turning and propulsion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional mechanical steering and propulsion systems are used, then the system structure is established, but the operator control precision and efficiency deteriorate
Solution Approach 1:
The patent replaces traditional mechanical cable-based steering mechanisms with electronic sensors and actuators. Motion sensors detect foot pedal positions and convert them to electronic signals that control the rudder and propeller, eliminating the need for mechanical linkages and improving both precision and ease of operation.
Solution Approach 2:
The patent introduces foot pedals as intermediary control devices between the operator and the boat's propulsion/steering system. The pedals translate foot movements into precise control signals, providing a more intuitive and accurate control interface compared to traditional mechanical levers or cables.
2Adaptability or versatility
If complex mechanical systems are used for simultaneous steering and propulsion control, then the system functionality is established, but the device complexity increases
Solution Approach 1:
The patent implements a unified control system where a single set of foot pedals controls both propulsion speed and steering direction simultaneously. The motion sensors and control algorithm process pedal inputs to generate coordinated commands for both the propeller and rudder, eliminating the need for separate mechanical systems for each function.
Solution Approach 2:
The patent replaces complex mechanical linkages that would be needed to simultaneously control propulsion and steering with an electronic control system. The electronic architecture can independently adjust multiple parameters (thrust, rudder angle) based on simple pedal inputs, dramatically reducing mechanical complexity while maintaining full functionality.
3Speed
If manual mechanical adjustments are used, then the system is simple, but the maneuverability and response speed deteriorate
Solution Approach 1:
The patent replaces slow mechanical cable adjustments with electronic actuators that respond instantaneously to sensor inputs. When the operator moves the foot pedals, motion sensors detect the change and immediately adjust propeller thrust and rudder angle, providing rapid response times that enhance both maneuverability and operational ease.
Solution Approach 2:
The patent implements feedback loops where motion sensors continuously monitor foot pedal positions and adjust propulsion/steering commands in real-time. This closed-loop control ensures that the boat responds precisely and quickly to operator inputs, improving response speed while maintaining intuitive ease of operation.

AI summary
Techniques are disclosed to enable a system for controlling the propulsion and steering of a boat by a boat operator. The boat has at least one propulsion and steering motor assembly connected to the boat with a propeller, and a propulsion motor. It also has left and right pivoting pedals to provide a signal that controls the angle of the propeller so that if the left pedal is pivoted in a first pivot direction by a first percentage and the right pedal is pivoted in a second pivot direction by a second percentage, the boat executes a turn, moves forward, or moves in reverse.
