Innovation Solution

A modular LED light fixture design featuring a housing with a curved front panel, multiple LED modules with heat sinks and lenses that converge light into a concentrated area, and adjustable modules that can be combined to achieve desired light distribution patterns, including the use of red, orange, green, blue, and broad-spectrum white LEDs, along with a controller for power management and a cooling system.

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 spectral breadth are insufficient

Engineering Contradiction:

Improveenergy efficiencyVSAvoidluminous output

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 LEDs (red, blue, green, UV). These modular units can be individually optimized and combined to achieve both high luminous output and broad spectral coverage while maintaining LED energy efficiency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple LED modules emitting different wavelengths are combined in a single fixture to produce broad-spectrum light. The convergence of light from multiple modules at a focal point creates high-intensity illumination across a wide spectral range, resolving the contradiction between luminous output and spectral breadth.

Inventive Principle:

Principle #5Merging (Combining)

2Use of energy by moving object

If traditional LED fixtures are used, then energy efficiency is improved, but spectral breadth is insufficient

Engineering Contradiction:

Improveenergy efficiencyVSAvoidspectral breadth

Core Design Contradiction:

Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The spectral output is segmented into discrete wavelength components (UV, blue, green, red) provided by separate LED modules. This segmentation allows each module to be optimized for its specific wavelength range while collectively providing comprehensive spectral coverage for horticultural applications.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fixture design incorporates multiple LED types (red, blue, green, UV) within a single system, making it universally applicable to various horticultural needs. The modular architecture allows the spectral composition to be adjusted for different plant types and growth stages while maintaining LED energy efficiency.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Illumination intensity

If LED modules are arranged to converge light, then luminous intensity is improved, but light distribution uniformity may worsen

Engineering Contradiction:

Improveconcentrated light intensityVSAvoidlight distribution uniformity

Core Design Contradiction:

Illumination intensityVSStability of the object's composition

Solution Approach 1:

The LED modules are arranged in a curved, three-dimensional configuration rather than a flat linear array. This spatial arrangement in multiple dimensions allows light to converge at a focal point while the curved geometry distributes the light source across different angles, maintaining both intensity concentration and distribution uniformity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

Different regions of the curved LED array are positioned to emit light at specific angles, with each local section optimized for its particular function. The varying positions and orientations of individual modules across the curve create both concentrated illumination at the target and uniform distribution across the illuminated area.

Inventive Principle:

Principle #3Local quality
