Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If high pressure sodium or fluorescent lamps are used for plant growth, then plant growth can be promoted, but heat is generated that could harm the plants

Engineering Contradiction:

Improvelight output for plant growthVSAvoidheat generation

Core Design Contradiction:

Illumination intensityVSTemperature

Solution Approach 1:

The patent replaces traditional high pressure sodium or fluorescent lamp systems with LED (Light Emitting Diode) technology. LEDs convert electrical energy directly to light through electroluminescence, producing significantly less heat compared to the thermal radiation mechanisms of traditional lamps. This substitution resolves the contradiction by maintaining plant growth promotion while eliminating harmful heat generation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Illumination intensity

If high pressure sodium or fluorescent lamps are used for plant growth, then plant growth can be promoted, but significant electricity is required

Engineering Contradiction:

Improvelight output for plant growthVSAvoidelectricity consumption

Core Design Contradiction:

Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The patent substitutes traditional lamp systems with LED technology, which has significantly higher energy efficiency. LEDs convert a much larger proportion of electrical energy into light output compared to the thermal conversion processes in traditional lamps, thereby reducing electricity consumption while maintaining the required illumination intensity for plant growth.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Illumination intensity

If high pressure sodium or fluorescent lamps are used for plant growth, then plant growth can be promoted, but frequent bulb replacement is required

Engineering Contradiction:

Improvelight output for plant growthVSAvoidbulb lifespan

Core Design Contradiction:

Illumination intensityVSDuration of action of stationary object

Solution Approach 1:

The patent replaces traditional lamps with LED modules that have substantially longer operational lifespans. LED technology typically provides 25,000-50,000 hours of operation compared to the much shorter lifespan of traditional bulbs, eliminating the need for frequent replacements while maintaining consistent light output for plant growth promotion.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Illumination intensity

If high pressure sodium or fluorescent lamps are used for plant growth, then plant growth can be promoted, but the scope of wave lengths of light provided is limited

Engineering Contradiction:

Improvelight output for plant growthVSAvoidlight wavelength spectrum

Core Design Contradiction:

Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The patent divides the lighting system into multiple LED modules, each emitting at different wavelengths (e.g., blue, red, green, white). This segmentation allows the system to provide a comprehensive spectrum of light wavelengths that can be individually optimized for different plant growth stages and requirements, overcoming the limited spectral output of traditional single-source lamps.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates a multi-functional lighting system where different LED modules can serve different functions - some optimized for photosynthesis (red/blue wavelengths), others for plant morphology control (green wavelengths), and white LEDs for overall illumination. This multi-functionality provides adaptability across various plant types and growth conditions while maintaining high illumination intensity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
