Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple wind turbines are arranged in a conventional multi-rotor system with predetermined layout, then the system can generate electric power, but the wind flow interference between units reduces overall output efficiency

Engineering Contradiction:
Improveoverall outputVSAvoidwind flow interference loss
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The system divides the wind power generation into multiple independent units (first, second, and third wind turbines) with individual casings and rotors. Each unit operates semi-independently, allowing optimization of wind flow paths for each segment while maintaining overall system productivity. This segmentation enables the wind flow to be utilized more efficiently across multiple units rather than having one large unit suffering from interference effects.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The casings are designed with asymmetric vortex generation structures that create controlled rotational flow patterns. The first and second casings generate vortexes in opposite directions, while the third casing generates vortexes in a coordinated manner. This asymmetric vortex configuration optimizes wind flow acceleration and reduces interference between adjacent units, improving overall energy capture efficiency.

Inventive Principle:
Principle #4Asymmetry

2Power

If supersized wind turbines are used to increase output, then electric power generation capacity increases, but noise and environmental impact increase

Engineering Contradiction:
Improveelectric power outputVSAvoidnoise and environmental impact
Core Design Contradiction:
PowerVSObject-affected harmful factors

Solution Approach 1:

Instead of using a single supersized wind turbine, the system employs multiple smaller-scale wind turbines (first, second, and third wind turbines) arranged in a coordinated configuration. This segmentation achieves comparable or superior power output while reducing aerodynamic noise and environmental impact associated with extremely large single units. The distributed configuration allows better integration with the environment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a single large-scale vertical configuration to a multi-unit three-dimensional arrangement with casings positioned at different heights and locations. This dimensional redistribution of power generation capacity allows the system to achieve high output while maintaining smaller individual unit sizes, thereby reducing noise and visual impact on the environment.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Area of stationary object

If casings are positioned close together to reduce space, then land use efficiency improves, but wind flow interference increases reducing output

Engineering Contradiction:
Improveland use efficiencyVSAvoidsystem output
Core Design Contradiction:
Area of stationary objectVSProductivity

Solution Approach 1:

The casings are equipped with vortex generation structures that create controlled rotational flow patterns before the wind reaches the rotors. This preliminary vortex generation accelerates and directs the wind flow, ensuring that even when casings are positioned relatively close together, each unit receives sufficient high-velocity wind flow. This pre-conditioning of the wind flow eliminates the need for large spacing between units while maintaining high output.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system changes the flow parameters of the wind by generating vortexes within the casings. This vortex generation transforms the wind flow characteristics, creating regions of accelerated flow and reduced pressure that enhance the wind's kinetic energy. By modifying the flow parameters rather than increasing spacing, the system achieves high productivity in a compact area configuration.

Inventive Principle:
Principle #35Parameter changes

4Productivity

If conventional multi-rotor systems are used, then multiple units can operate, but synergistic effects are not achieved and efficiency increase is limited to 1-3%

Engineering Contradiction:
Improvesystem outputVSAvoidlack of synergistic effect
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The system employs asymmetric vortex generation where the first and second casings create vortexes in opposite directions, and the third casing generates vortexes in a coordinated pattern. This asymmetric configuration creates synergistic interactions between the wind flows from different units, producing enhanced overall output that exceeds the simple sum of individual unit performances by more than 3%, achieving true synergistic effects.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The vortex generation structures in the casings create continuous rotational flow patterns that maintain high-velocity wind flow throughout the operation. This continuous useful action ensures that all three wind turbines operate at optimized efficiency levels simultaneously, with the vortexes from different units interacting constructively to maintain sustained high productivity rather than experiencing intermittent or isolated performance peaks.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A fluid power generation device is configured to provide electric power generation using fluid action, and comprises multiple power generation mechanisms. Each power generation mechanism comprises: a casing that allows a fluid to pass through its internal space; and a power generation unit arranged within the casing, and configured to perform electric power generation using the fluid action. The casing is configured to generate vortexes in the vicinity of its fluid outlet. The multiple casings are arranged with spaces as intervals between them. Each casing generates vortexes in the vicinity of its fluid outlet. Furthermore, such an arrangement provides an interaction effect between the vortexes generated in the vicinity of the fluid outlets of the multipole casings arranged with the spaces as intervals between them. This provides a synergistic effect for accelerating the inner flow based on the interaction between the power generation mechanisms.
