Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wind energy systems are integrated into building structures, then architectural integration is improved, but visual impact and device complexity increase

Engineering Contradiction:
Improvearchitectural integrationVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent embeds wind turbine components within building structures. The rotor assembly is positioned within a housing that is integrated into the building facade or roof structure. The generator and other mechanical components are nested within the building envelope, making the system architecturally integrated while managing visual impact through strategic placement and design of visible elements.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The building structure serves multiple functions: it provides the housing for the wind turbine system, structural support for the rotor assembly, and maintains architectural aesthetics. The system combines energy generation with building integration, allowing the same structure to fulfill both architectural and functional roles simultaneously.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If blade shape is optimized for aerodynamic efficiency, then power generation efficiency is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvepower generation efficiencyVSAvoidmanufacturing precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent applies aerodynamic optimization to critical portions of the blade rather than requiring perfect precision across the entire blade structure. By focusing aerodynamic shaping on the portions of the blade that most directly interact with wind flow (the leading edge and pressure surfaces), the system achieves good efficiency without requiring extreme manufacturing precision throughout the entire blade assembly.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

The present invention relates to the energy efficiency of buildings and, in particular, it addresses the problem of exploiting the generation of electricity from wind sources in the building sector, indicating some essential characteristics of a micro-wind generation system suitable for architectural integration in new buildings, conceived according to the logic of energy efficiency, so as not to be visually evident like the systems according to the known art. The invention is based on the intuition of exploiting the external surfaces of the building on which the micro-wind system is installed, making it the element that intercepts the flow of the wind, i.e., the larger element that is normally difficult to architecturally integrate into the building. In particular, the external walls or the pitches of the roof that are more exposed to the wind are exploited. The system according to the invention then indicates some essential featues that characterize these external surfaces of the building to channel the intercepted wind towards suitable rotating elements equipped with wind turbines. These rotating elements are positioned at the exit of the wind channeling ducts so that the air coming out of these ducts invests suitable wind blades thus rotating these rotating elements; the latter being part of an electrical generator that transforms part of the mechanical energy transmitted to said rotating elements into electrical energy.
