Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a pump with high flow rate is used to create a powerful current, then the current strength is improved, but the device complexity and cost increase
Solution Approach 1:
The domed element with aeronautical profile uses curved surfaces to generate a complementary current through flow separation and vortex formation. The dome shape creates a low-pressure zone that draws water through the injection duct and generates a rotational current pattern, eliminating the need for high-flow pumps while maintaining strong current intensity for swimming resistance.
Solution Approach 2:
The domed element acts as an intermediary device between the water supply and the swimmer. It transforms ordinary water flow into a powerful current by creating a controlled flow separation zone and vortex structure, mediating the conversion of simple water movement into effective swimming resistance without requiring high-power pumping equipment.
2Force
If a pump with high flow rate is used to create a powerful current, then the current strength is improved, but the energy consumption increases
Solution Approach 1:
The invention converts the naturally dissipating kinetic energy of water flow into useful current strength by strategically positioning the domed element to capture and redirect flow. The flow separation and vortex formation, which would normally represent energy loss, are harnessed to create the complementary current that provides swimming resistance, thereby converting potential energy waste into beneficial current force.
Solution Approach 2:
The domed element changes the flow parameters (velocity distribution, pressure distribution, flow direction) by introducing curvature and confinement. This transforms the water flow from a simple linear movement into a complex vortex pattern with enhanced local velocity and pressure gradients, generating strong current force without proportionally increasing the energy input from the pump.
3Speed
If the primary flow speed is increased to form a powerful current, then the current effectiveness is improved, but the device complexity increases
Solution Approach 1:
The domed element with aeronautical profile uses its curved geometry to accelerate and direct the primary flow. The dome shape creates a converging-diverging flow path that naturally increases flow speed through pressure gradient effects, while the curved surfaces guide the flow to generate the complementary vortex current, achieving high-speed flow without complex mechanical acceleration devices.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system generates a powerful and efficient current that effectively opposes the swimmer's propulsive force, preventing easy ascension towards the current source by maximizing drag, thus enhancing swimming performance without increasing pump flow rates.
Implementation Method 1
The domed element has an aeronautical profile. This profile promotes the development of a current complementary to the primary flow, by flow on the outer walls of the domed element of a return current.
Implementation Method 2
The document FR2867500 discloses a device for increasing the flow rate of a water jet by Venturi effect.
