Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If conventional wind power generation rotates huge facilities through wind power to induce electrons, then electric energy can be generated, but the device becomes inefficient due to restricted location conditions, difficulty in management and maintenance, and high costs

Engineering Contradiction:

Improveelectric energy generationVSAvoidfacility size and installation complexity

Core Design Contradiction:

PowerVSDevice complexity

Solution Approach 1:

The patent divides the piezoelectric power generation system into multiple independent cantilever units with piezoelectric elements, allowing the system to function without huge rotating facilities. Each cantilever operates independently to convert wind-induced vibrations into electricity, enabling modular deployment in various locations without complex installation requirements

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent replaces the conventional mechanical rotation system (huge propellers rotating to induce electrons) with a piezoelectric vibration-based system. Instead of using large-scale mechanical rotation to generate electricity, the system uses piezoelectric elements that convert mechanical vibrations from wind directly into electrical energy through the piezoelectric effect, eliminating the need for huge facilities

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Power

If conventional piezoelectric power generator uses rotational blades to rotate shaft through wind power, then electric energy is generated, but wind energy is lost by rotating the rotational body resulting in high energy loss

Engineering Contradiction:

Improveelectric energy generationVSAvoidwind energy loss

Core Design Contradiction:

PowerVSLoss of energy

Solution Approach 1:

The patent employs cantilevers that vibrate in response to wind forces rather than rotating. The piezoelectric elements mounted on these cantilevers convert the vibrational mechanical energy directly into electrical energy, avoiding the energy losses associated with rotational inertia and friction that plague conventional wind turbine systems

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The cantilevers exhibit periodic vibrational motion when subjected to wind forces, creating rhythmic mechanical stimulation of the piezoelectric elements. This periodic action continuously generates electrical impulses that can be harvested, converting wind energy efficiently without the energy-wasting rotational mechanism

Inventive Principle:

Principle #19Periodic action

3Power

If conventional piezoelectric power generator restricts usable wind direction and requires separate equipment such as inclined entrance, then power generation can be conducted, but the device complexity increases and adaptability decreases

Engineering Contradiction:

Improvewind power generationVSAvoidwind direction adaptability

Core Design Contradiction:

PowerVSAdaptability or versatility

Solution Approach 1:

The patent designs the cantilever-based piezoelectric system to respond to wind from any direction. The multiple cantilevers are arranged to capture wind-induced vibrations regardless of direction, making the system universally applicable to various wind conditions without requiring directional adjustment mechanisms or additional equipment for different orientations

Inventive Principle:

Principle #6Universality (Multi-functionality)
