Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If traditional windmills or hydroelectric power stations are used for power generation, then power can be generated from dynamic fluid flow, but the power output is limited and environmental impact increases

Engineering Contradiction:
Improvepower generation capacityVSAvoidenvironmental impact
Core Design Contradiction:
PowerVSObject-affected harmful factors

Solution Approach 1:

The invention divides the power generation system into multiple independent rotating bodies (at least two) that operate simultaneously in the same fluid flow. Each body generates power independently, and their combined output significantly increases total power generation capacity while maintaining a compact footprint that reduces environmental disruption compared to large-scale hydroelectric dams.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from traditional horizontal-axis windmills to vertical-axis rotating bodies that are partially immersed in the fluid flow. This dimensional change allows the bodies to exploit both surface and subsurface flow dynamics, increasing energy capture efficiency and power output while minimizing above-ground infrastructure and visual impact.

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

2Power

If hydroelectric power stations with dams are constructed, then large amounts of power can be generated, but costly facilities with large planning and proportions are required along with important maintenance operations

Engineering Contradiction:
Improvepower generation capacityVSAvoidinfrastructure complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The invention extracts the essential power generation function from the complex dam infrastructure. By using free-standing rotating bodies that operate directly in the natural fluid flow without requiring dams, gates, or large reservoirs, the system achieves significant power generation with minimal civil engineering and infrastructure complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The rotating bodies are designed to operate autonomously in the natural fluid flow, with no requirement for external control systems, gate operations, or complex maintenance infrastructure. The bodies self-regulate their operation based on flow conditions, eliminating the need for costly operational and maintenance facilities.

Inventive Principle:
Principle #25Self-service

3Power

If traditional windmill designs are used, then power generation is achieved, but movement continuity is poor and power output is limited

Engineering Contradiction:
Improvepower outputVSAvoidmovement continuity
Core Design Contradiction:
PowerVSDuration of action of moving object

Solution Approach 1:

The invention merges multiple rotating bodies into a single power generation system, where each body contributes to the total power output. This combination ensures continuous operation as different bodies can operate at different phases, smoothing out fluctuations and maintaining consistent power generation across varying flow conditions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The rotating bodies are designed to exploit periodic variations in fluid flow dynamics, with each body completing full rotation cycles that capture energy from both surface waves and subsurface currents. This periodic motion ensures continuous power generation rather than intermittent operation.

Inventive Principle:
Principle #19Periodic action

AI summary

An arrangement for generating energy made up of at least two rotating bodies of revolution partially immersed in a dynamic fluid. The at least two rotating bodies of revolution have their longitudinal axis of rotation located perpendicularly to the flow of the fluid, and are further associated to support means and to drive means, being immersed about 30% of their diameter. One of the at least two rotating bodies of revolution is located upstream of said dynamic fluid with its longitudinal axis of rotation located in a longitudinal slider of the support means with the possibility of translation and variable rotation speed. The other of the at least two rotating bodies of revolution is located downstream of the dynamic fluid, with its longitudinal axis of rotation being attached to the support means, and with a rotation synchronized with the flow speed of the dynamic fluid.
