Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If vertical axis wind turbines are used, then manufacturing cost is reduced, but efficiency decreases due to air resistance in return motion

Engineering Contradiction:

Improvemanufacturing costVSAvoidefficiency

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The turbine is divided into two functional parts: a vertical axis rotor for cost-effective manufacturing and horizontal axis wings for efficient wind capture. This segmentation allows each part to perform its optimal function - the vertical rotor reduces manufacturing complexity while the horizontal wings eliminate air resistance issues in the return motion

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent combines vertical axis and horizontal axis wind turbine concepts into a single hybrid structure. The vertical rotor shaft with horizontal wings creates a system that merges the manufacturing advantages of vertical turbines with the aerodynamic efficiency of horizontal turbines

Inventive Principle:

Principle #5Merging (Combining)

2Productivity

If horizontal axis wind turbines are used, then efficiency is improved by controlling rotor speed through angle of attack, but manufacturing cost and structure size increase

Engineering Contradiction:

ImproveefficiencyVSAvoidmanufacturing cost

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The turbine separates the efficiency-function (handled by horizontal wings with adjustable angle of attack) from the structural support function (handled by the vertical mast and rotor hub). This allows the expensive aerodynamic components to be smaller and more efficient while the structural components remain simple and cost-effective

Inventive Principle:

Principle #1Segmentation

3Power

If horizontal axis wind turbines are used, then power generation is improved, but kinetic energy is lost to movement of large rotor blades

Engineering Contradiction:

Improvepower generationVSAvoidkinetic energy loss

Core Design Contradiction:

PowerVSLoss of energy

Solution Approach 1:

The turbine separates the wind capture function (horizontal wings) from the power generation function (vertical rotor). The horizontal wings accelerate wind toward the vertical rotor, ensuring that kinetic energy is directed efficiently into the rotor blades rather than being lost to moving large horizontal blades through the wind stream

Inventive Principle:

Principle #1Segmentation

4Power

If sail technology is used to increase wind speed at rotor, then power generation is improved, but sail must be retracted in bad weather causing interruption

Engineering Contradiction:

Improvepower generationVSAvoidoperational continuity

Core Design Contradiction:

PowerVSReliability

Solution Approach 1:

The vertical rotor design with horizontal wings allows the entire structure to rotate dynamically to face the wind from any direction. This dynamic adaptability eliminates the need to retract sails in bad weather, as the turbine can orient itself to maintain power generation across varying wind conditions

Inventive Principle:

Principle #15Dynamics
