Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If floating structures use significant mass to counteract external forces, then stability is improved, but construction and operating costs increase

Engineering Contradiction:
ImprovestabilityVSAvoidstructural mass
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The patent applies the counterweight principle by using the floating structure's own weight as a counterbalance to external forces. The anchor system is designed so that the structure's mass itself provides stability against winds and currents, eliminating the need for additional heavy stabilization components. This is achieved through proper positioning and design of the anchor system that leverages the structure's inherent weight.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

2Stability of the object's composition

If floating structures use significant mass to counteract external forces, then stability is improved, but construction and operating costs increase

Engineering Contradiction:
ImprovestabilityVSAvoidconstruction and operating costs
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent applies the counterweight principle by using the floating structure's own weight as a counterbalance to external forces. The anchor system is designed so that the structure's mass itself provides stability against winds and currents, eliminating the need for additional heavy stabilization components. This is achieved through proper positioning and design of the anchor system that leverages the structure's inherent weight.

3Stability of the object's composition

If traditional oblique moorings are used to hold floating structures, then anchoring is achieved, but device complexity and costs increase

Engineering Contradiction:
ImproveanchoringVSAvoidmooring system complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent inverts the traditional anchoring approach by transitioning from oblique moorings to a vertical anchor system. Instead of using angled cables that extend from the structure to anchor points on the seabed, the invention employs a vertical anchor that aligns directly beneath the floating structure. This vertical configuration simplifies the mooring system by eliminating the need for complex angled cable arrangements and multiple anchor points, reducing both device complexity and associated costs.

Principle #13The other way round (Inversion)

4Power

If renewable energy sources like wind and sun are used, then electricity production is achieved, but intermittency reduces reliability

Engineering Contradiction:
Improveelectricity productionVSAvoidenergy availability
Core Design Contradiction:
PowerVSReliability

Solution Approach 1:

The patent applies periodic action by utilizing the predictable cyclic nature of tidal movements for energy generation. The anchor system incorporates mechanisms that convert the regular rising and falling of tides into electrical energy, providing a consistent and reliable power source. This periodic exploitation of tidal cycles ensures continuous energy production unlike intermittent wind and solar sources, as tides follow predictable daily and monthly patterns that can be reliably harnessed.

Inventive Principle:
Principle #19Periodic action

Function Achieved in This Case

The system enhances stability and reduces structural mass and mooring costs while generating predictable energy from tidal movements, optimizing floating structures and improving energy efficiency.

Implementation Method 1

the present invention uses the power contained in the movement of water during the tides to produce additional electricity. Indeed, the surface of the sea, due to its immensity subject to the winds, can constitute an important source of wave energy by using waves. And beneath the surface, the tides move immeasurable masses of water in a continuous, perfectly predictable alternating movement.
