Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If hand-held throttles are used to control motorized surfboards, then the motor can be controlled to increase thrust, but the system becomes difficult to control and even talented surfers struggle to perform basic maneuvers
Solution Approach 1:
The surfboard system automatically detects rider tilt and foot position through sensors and adjusts motor thrust and steering accordingly, eliminating the need for manual throttle control. The system serves itself by autonomously responding to rider inputs through body positioning rather than requiring manual intervention via hand-held throttles.
Solution Approach 2:
The system incorporates tilt sensors and force sensors that continuously monitor rider position and provide feedback to the control system. This feedback loop enables automatic adjustment of motor parameters based on rider姿态, making the system responsive and easy to control without manual throttles.
2Ease of operation
If tilt sensors and force sensors are integrated into the board to detect rider positioning, then automatic stabilization and maneuvering can be achieved, but the device complexity increases
Solution Approach 1:
Multiple sensors (tilt sensors, force sensors) and the motor control system are integrated into a unified control architecture that processes sensor data and coordinates motor responses. This merging reduces overall system complexity by creating a cohesive control system rather than separate independent components.
Solution Approach 2:
The sensor system serves multiple functions: detecting rider tilt for stabilization, detecting foot position for maneuver control, and providing feedback for automatic thrust adjustment. This multi-functionality reduces the need for separate specialized sensors for each function, thereby managing complexity.
3Adaptability or versatility
If the steering system directs water flow to turn the watercraft based on tilt sensor detection, then maneuverability is improved, but the system requires precise coordination between sensors and steering
Solution Approach 1:
The steering system uses real-time feedback from tilt sensors to automatically adjust water flow direction. The control system continuously monitors tilt data and coordinates steering actuator responses, creating a seamless feedback loop that simplifies maneuver control while maintaining high adaptability.
Solution Approach 2:
The system replaces traditional mechanical steering linkages with a control system that uses sensor data to electronically control water flow direction. This substitution of mechanical systems with sensor-based control reduces mechanical complexity while improving maneuverability and coordination precision.

AI summary
A board can have an upward-facing side arranged to enable a person to stand on the board while surfing. A motor can be attached to a downward-facing side of the board to propel the board. A computer system can use data from sensors and a steering system to actively respond to actions from the person riding on the board.
