Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water sports devices, such as foilboards, are unstable during acceleration and turning, requiring users to shift their body weight to prevent capsizing, making them difficult to use and learn.
Innovation Solution
The water sports device features automatic self-stabilization through a control unit that adjusts thrust vector control, using actuators like motors, flaps, nozzles, and fins, and sensors to maintain stability based on device position, speed, and user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional water sports equipment is used without active stabilization, then the device structure remains simple, but the equipment becomes unstable during acceleration and turning, requiring users to shift body weight to prevent capsizing
Solution Approach 1:
The water sports equipment performs self-stabilization automatically through the control unit and actuators without requiring user intervention. The system monitors its own state via sensors and makes corrective adjustments independently, allowing the equipment to serve its own stabilization needs rather than relying on user balance control
Solution Approach 2:
The patent replaces the mechanical balance control system (user body weight shifting) with an automated control system comprising electronic sensors, a control unit, and actuators. This substitution transforms the stabilization mechanism from manual mechanical adjustment to automated sensor-based control with motorized actuation
2Ease of operation
If active stabilization with control unit and actuators is implemented, then ease of operation improves by reducing user burden, but device complexity increases due to additional components
Solution Approach 1:
The stabilization system operates autonomously without requiring user attention or manual adjustment. The control unit continuously monitors sensor data and automatically actuates the actuators to maintain stability, freeing the user to focus on navigation and enjoyment rather than balance maintenance
Solution Approach 2:
The system implements a closed-loop feedback mechanism where sensors continuously monitor the equipment's orientation and position, the control unit processes this data to determine stability deviations, and actuators apply corrective forces. This feedback loop enables automatic adaptation to changing conditions while maintaining ease of operation
