Motorized Board Foot Pedal Control for Independent Water Propulsion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water sports, such as surfing and water-skiing, face limitations like dependence on wave conditions and boat operation, leaving a gap for a more versatile and user-controlled water activity.
Innovation Solution
A motorized board with a rotatable foot pedal and integrated motor allows users to control speed and direction by foot, featuring a waterproof foot pedal with sensors, a small outboard motor, and an adjustable wing for enhanced propulsion and stability, enabling independent water travel without waves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional water sports like surfing are used, then users can enjoy wave-based activities, but users are dependent on wave conditions and cannot control speed and direction independently
Solution Approach 1:
The board enables the user to control its own propulsion and direction through integrated control mechanisms (foot pedals, handlebars, or digital controls) that directly operate the motor and steering system, eliminating dependency on external wave conditions or boat operators
Solution Approach 2:
The board combines multiple functions into a single platform: propulsion via motor, steering via integrated controls, and user-operated navigation, allowing it to function independently of waves or boats while providing comprehensive control to the user
2Adaptability or versatility
If water-skiing is used, then users can be pulled across water, but users are dependent on boat operation and cannot operate independently
Solution Approach 1:
The invention extracts the propulsion function from the external boat and integrates it directly into the board through an onboard motor system, eliminating the need for a separate boat and enabling independent operation
Solution Approach 2:
The board merges the propulsion system, steering mechanism, and user control interface into a single integrated unit, combining functions that were previously separated between the boat and the water sport equipment
3Ease of operation
If a motorized system is added to the board, then users can control speed and direction, but the device complexity increases
Solution Approach 1:
The patent introduces intermediary control mechanisms (such as foot pedals, handlebars, or digital interfaces) that simplify the interaction between the user and the motor system, making complex motor control accessible through intuitive, easy-to-operate interfaces
Solution Approach 2:
The invention replaces complex manual mechanical control systems with motorized actuation and electronic control, using electric motors and digital controllers to manage propulsion and steering, thereby reducing the mechanical complexity the user must directly manage

AI summary
A motorized board similar to a surf board is presented for use on a water surface. The motorized board includes a base board having a front end and a back end, a foot pedal on the base board, wherein the foot pedal is rotatable on the base board, and a motor coupled to the base board and connected to a propeller at the back end, the motor being controlled by the foot pedal. A user can stand on the board and turn the motor on with his foot, as well as control the speed with his foot to ride on a water surface with or without waves.
