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 structure and affects energy production.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the floating wind power generation device uses a simple buoyant structure, then the device complexity is reduced, but the stability of the device is worsened due to roll motion from sea waves
Solution Approach 1:
The patent applies nesting by placing the auxiliary buoyant body inside the main buoyant body, creating a nested configuration where the auxiliary buoyant body is positioned within the hollow interior of the main buoyant body. This nested structure provides stability against roll motion while maintaining a relatively simple overall device complexity.
Solution Approach 2:
The patent employs counterweight principles by using the auxiliary buoyant body as a stabilizing element that counteracts the roll motion of the main buoyant body. The auxiliary buoyant body acts as a counterbalancing mass that reduces the amplitude of rolling movements, thereby improving floating stability without significantly increasing structural complexity.
2Stability of the object's composition
If the floating wind power generation device adds stabilization mechanisms, then the stability is improved, but the device complexity increases
Solution Approach 1:
The stabilization mechanism is achieved through nesting the auxiliary buoyant body within the main buoyant body, which provides stability without requiring complex external stabilization structures. This approach improves floating stability while keeping the overall device complexity relatively low.
Solution Approach 2:
The auxiliary buoyant body provides self-stabilizing functionality through its inherent buoyancy and positioning within the main buoyant body. The system uses the natural buoyant forces and geometric configuration to automatically counteract roll motion, eliminating the need for complex active stabilization systems with sensors and actuators.
3Stability of the object's composition
If the device uses larger buoyant bodies to improve stability, then the stability is improved, but the use of energy increases due to larger surface area exposed to waves
Solution Approach 1:
The nested configuration allows the auxiliary buoyant body to be positioned inside the main buoyant body, creating a compact structure that improves stability without proportionally increasing the external surface area. This reduces wave exposure and energy consumption compared to a single large buoyant body of equivalent stability.
Solution Approach 2:
The buoyant system is segmented into two separate buoyant bodies (main and auxiliary) with distinct functions. The main buoyant body provides primary buoyancy while the auxiliary buoyant body provides stabilization, allowing optimization of each component's size and shape to minimize wave exposure and energy consumption while maintaining stability.
