Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electric hydrofoil uses a static mechanical system with manual control only, then the device achieves simple construction and low cost, but the difficulty of operation increases significantly for beginners due to the need for precise manual control of angle of attack and balance
Solution Approach 1:
The control system continuously receives feedback from sensors measuring the electric hydrofoil's position, orientation, and motion parameters. This feedback is processed by the control unit, which automatically adjusts motor power and steering angle to maintain stable flight, eliminating the need for manual balance control by the operator.
Solution Approach 2:
The electric hydrofoil performs self-balancing and self-steering through its automated control system. The device monitors its own state via sensors and independently makes corrections to maintain stable operation, making the system serve itself rather than requiring constant manual intervention.
2Reliability
If the electric hydrofoil implements an automated assistance system with sensors and control units, then the ease of operation improves for beginners, but the device complexity and cost increase
Solution Approach 1:
Multiple sensors continuously monitor flight parameters including position, orientation, and motion. The control unit processes this feedback in real-time and automatically adjusts motor power and steering to maintain stable operation, significantly improving reliability and reducing falls.
Solution Approach 2:
The patent replaces manual mechanical balance control with an electronic automated control system. Sensors and control units substitute for the operator's manual balancing actions, providing more precise and reliable stability control while reducing the skill requirement.
3Ease of operation
If the electric hydrofoil relies on manual balance control by the operator, then the construction remains simple, but the learning process becomes dangerous due to frequent falls and potential injuries
Solution Approach 1:
The control system continuously monitors flight stability through sensors and automatically makes corrections to prevent loss of control. This feedback mechanism reduces frequent falls and the associated injury risk that plagues manual operation, especially for beginners.
Solution Approach 2:
The electric hydrofoil performs self-balancing and self-correction through its automated control system, eliminating the need for the operator to manually maintain balance. This reduces the frequency of falls and injuries that occur when operators lack the skill to properly control the device.

Function Achieved in This Case
Facilitates easier and safer learning for beginners by preventing falls and reducing the risk of injury, allowing for safer riding across various skill levels.
Implementation Method 1
At high speed, the flow of fluid around the wings causes a pressure difference between their two half-surfaces, resulting in lift. It allows the above-water platform, together with the surfer on it, to be raised about 40 cm above the water.
Implementation Method 2
The electronic speed controller of the electric motor ensures the conversion of direct current from the battery into alternating current flowing through the three phases of the electric motor.
