Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If traditional LED fixtures are used, then energy efficiency is improved, but luminous output and spectrum breadth are insufficient

Engineering Contradiction:

Improveenergy efficiencyVSAvoidluminous output and spectrum breadth

Core Design Contradiction:

Use of energy by moving objectVSIllumination intensity

Solution Approach 1:

The lighting system is divided into multiple independent LED modules, each containing specific wavelength-emitting LEDs (e.g., blue, green, red). These modules can be individually selected and combined to achieve the desired broad spectrum while maintaining energy efficiency of each module.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple LED modules emitting different wavelengths are combined within a single fixture to produce a broad-spectrum output. The fixture integrates blue, green, and red LED modules along with phosphor converters to merge their outputs into a comprehensive spectrum suitable for horticulture.

Inventive Principle:

Principle #5Merging (Combining)

2Ease of manufacture

If fixed LED module configuration is used, then manufacturing simplicity is maintained, but adaptability to different lighting requirements is reduced

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidadaptability to different lighting requirements

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The fixture incorporates adjustable LED modules that can be repositioned along the fixture body, and interchangeable lenses that can be swapped to change beam angles and distribution patterns. This dynamic configuration allows the same fixture to adapt to various lighting requirements without requiring custom manufacturing.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The fixture design incorporates universal mounting mechanisms and standardized interfaces that allow the same fixture body to accommodate different LED modules and lens combinations, enabling one fixture design to serve multiple lighting applications.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Illumination intensity

If high luminous output is achieved, then illumination intensity is improved, but heat generation increases

Engineering Contradiction:

Improveluminous outputVSAvoidheat generation

Core Design Contradiction:

Illumination intensityVSTemperature

Solution Approach 1:

The heat management system extracts heat from the LED modules through dedicated heat sinks attached to each module. The heat sinks are thermally coupled to the LED sources and conduct heat away from the high-power LEDs, preventing thermal accumulation that would reduce luminous output.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Thermal interface materials and heat sink structures act as intermediaries between the LED sources and the external environment, facilitating efficient heat transfer while maintaining optimal operating temperatures for high luminous output.

Inventive Principle:

Principle #24Intermediary (Mediator)
