Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Floating offshore wind power generation devices experience reduced power generation efficiency due to roll motion caused by sea waves, which destabilizes the floating structure.
Innovation Solution
A floating wind power generation device comprising a main buoyant body, an auxiliary buoyant body with wind power generators, a location control system, an oscillation inhibiting mechanism, and a dock connection unit, which includes support frames, motion plates, rotation power generators, and absorption plates to absorb wave energy and maintain equilibrium, thereby stabilizing the structure and enhancing power generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the floating wind power generation device is exposed to sea waves, then wind power generation can be performed, but roll motion occurs which lowers power generation efficiency
Solution Approach 1:
The patent converts the harmful roll motion caused by sea waves into useful energy by installing oscillation inhibiting means that capture the wave energy and transform it into electrical energy through generators, thereby reducing the harmful effects while generating additional power
Solution Approach 2:
The patent employs oscillation inhibiting means including buoyant bodies and damping structures that counteract the roll motion caused by sea waves, providing stabilizing forces opposite to the direction of harmful motion to maintain structural stability
2Productivity
If the floating structure is stabilized to prevent roll motion, then power generation efficiency improves, but device complexity increases
Solution Approach 1:
The oscillation inhibiting means serves multiple functions: it stabilizes the floating structure against roll motion, captures wave energy for power generation, and provides additional buoyancy, thereby reducing the need for separate stabilization systems and minimizing overall complexity

AI summary
Provided is a floating wind power generation device comprising: a main buoyant body which has buoyancy, so as to float on the sea, and has a space portion provided in the center; an auxiliary buoyant body which has buoyancy and is connected to the main buoyancy and is connected to the main buoyant body by being inserted into the space portion of the main buoyant body; a plurality of wind power generators which are vertically provided on top of the auxiliary buoyant body and generate power; a location control means which is connected to the main buoyant body and controls the location of the main buoyant body; an oscillation inhibiting means which is connected to the main buoyant body and enables the main buoyant body to maintain an equilibrium state by absorbing the sea waves; and a dock connection unit which is connected to the main buoyant body and enables a ship to lie at anchor on the sea. A floating wind power generation device, having a plurality of wind power generators provided on top of an auxiliary buoyant body that is placed in a space portion of a main buoyant body, enables absorbing of the sea waves by means of vertical reciprocating motion energy, generated by means of an oscillation inhibiting means as well as a location control means, so as to prevent the main buoyant body from being affected by the waves and shaking and such that an equilibrium state of the main buoyant body can be maintained, thereby enabling stable wind power generation.
