Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If photovoltaic systems are installed at ground level separately from wind turbines, then both systems can operate independently, but additional ground area is sealed and not available for other uses

Engineering Contradiction:
Improveenergy generation capacityVSAvoidground area availability
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The patent combines wind turbine and photovoltaic systems into a single integrated structure where solar modules are mounted on the tower and around the rotor hub, allowing both energy generation systems to occupy the same spatial footprint and eliminating the need for separate ground installations

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The photovoltaic modules are nested around the wind turbine tower and rotor hub, with solar panels arranged in concentric patterns that utilize the vertical space and circumferential area of the tower structure, effectively placing one energy generation system within the spatial envelope of the other

Inventive Principle:
Principle #7Nested doll (Nesting)

2Productivity

If wind turbines and photovoltaic systems are installed separately on the same site, then combined power generation is possible, but the combination is not compact and uses more space

Engineering Contradiction:
Improvecombined power generationVSAvoidspace usage
Core Design Contradiction:
ProductivityVSVolume of moving object

Solution Approach 1:

The patent merges the wind turbine and photovoltaic systems into a single compact unit where solar modules are integrated onto the tower structure and rotor hub, achieving combined power generation from wind and solar sources within a minimal spatial footprint

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If solar module arrangement is fixed in position, then installation is simple, but the system cannot adapt to fluctuating wind and solar energy availability

Engineering Contradiction:
Improveinstallation simplicityVSAvoidenergy availability adaptation
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent incorporates movable and adjustable photovoltaic module arrangements that can change their position and orientation in response to varying wind and solar conditions, allowing the system to dynamically optimize energy capture while maintaining relatively simple installation through modular design

Inventive Principle:
Principle #15Dynamics
