Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional lighting devices emit red and blue light for plant growth, then photosynthesis is stimulated, but the light beam distribution is non-homogeneous and control precision is low

Engineering Contradiction:
Improveplant growth yieldVSAvoidlight beam control precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The lighting device is divided into multiple independent LED modules, each equipped with its own control circuit. This segmentation allows precise individual control of each module's light output, enabling accurate spatial and temporal control of the light beam while maintaining homogeneous distribution across the plant growth area.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device incorporates dynamic control capabilities through programmable control circuits that can adjust light intensity, wavelength composition, and timing patterns in real-time. This dynamic control allows optimization of light delivery to match plant physiological needs at different growth stages, improving productivity while maintaining precise control.

Inventive Principle:
Principle #15Dynamics

2Illumination intensity

If conventional lighting devices emit light without precise control, then device complexity is reduced, but light energy distribution homogeneity is poor

Engineering Contradiction:
Improvelight energy distribution homogeneityVSAvoidcontrol system complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

Different regions of the lighting device emit light with locally optimized characteristics. Each LED module can be independently configured to provide specific wavelengths and intensities appropriate for different plant zones, achieving homogeneous overall distribution through localized optimization without requiring complex centralized control.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The control system incorporates feedback mechanisms where each LED module monitors its own performance and automatically adjusts its output to maintain homogeneous light distribution. This self-regulating capability achieves uniform illumination without proportionally increasing control system complexity.

Inventive Principle:
Principle #25Self-service
