Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a fin system is installed on the water sports board, then propulsion and steering capability are improved, but turbulence and cavitation are generated which reduce stability
Solution Approach 1:
A water diffuser is introduced as an intermediary component between the fin system and the tail edge of the board. The diffuser mediates the turbulent water flow generated by the fin system, allowing it to transition to laminar flow before reaching the tail, thereby reducing cavitation and improving stability while maintaining propulsion effectiveness
Solution Approach 2:
The water diffuser changes the flow parameters of water by transitioning it from a turbulent state (with cavitation) to a laminar state. This parameter change occurs through the diffuser's geometric design which promotes flow smoothing and bubble dissolution, reducing the harmful effects of turbulence on board stability
2Ease of operation
If the fin system is positioned closer to the tail edge to improve maneuverability, then steering response is enhanced, but cavitation and turbulence increase reducing performance
Solution Approach 1:
The water diffuser serves as a mediator placed between the fin system and tail edge, enabling the fin system to be positioned optimally for steering response while the diffuser handles the turbulent flow management, preventing cavitation from affecting board performance
Solution Approach 2:
The harmful function of turbulent flow and cavitation is extracted from the system by introducing the water diffuser. The diffuser separates the beneficial steering response function from the harmful cavitation effect, allowing the fin system to provide enhanced maneuverability while the diffuser removes the detrimental turbulence
3Stability of the object's composition
If board volume is increased to improve stability at lower speeds, then lift and stability are enhanced, but overall performance and speed capability are reduced
Solution Approach 1:
The water diffuser utilizes hydraulic principles to manage water flow along the bottom surface of the board. By controlling the water flow regime (transitioning from turbulent to laminar), the diffuser enables improved stability without requiring increased board volume, thus maintaining speed performance while achieving enhanced stability through flow management rather than volume increase
