Solution Overview

Problem

In horticulture and other applications, operators of multichannel lighting systems face challenges in accurately controlling the spectral power distribution of light outputs due to interactions between different LED channels, leading to difficulties in creating desired light settings that balance color combinations and power limitations.

Innovation Solution

A user interface and method that provide a dynamic range of control values for each color, taking into account the interactions and power limitations between channels, allowing operators to define valid light settings by overlaying a dynamic scale onto a static scale, ensuring that adjustments in one channel's output do not exceed the system's capabilities, thereby optimizing light output.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If operators control each LED channel individually to maximum power output, then the light output intensity is improved, but the spectral power distribution becomes unbalanced due to interactions between channels

Engineering Contradiction:
Improvelight output intensityVSAvoidspectral power distribution accuracy
Core Design Contradiction:
Illumination intensityVSManufacturing precision

Solution Approach 1:

The patent implements dynamic adjustment of control value ranges based on current channel settings. When one channel's output is changed, the system recalculate and updates the valid range for other channels' control values in real-time, allowing operators to achieve balanced spectral power distribution while maintaining high light output intensity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system provides feedback to operators by displaying the dynamic range of valid control values for each channel. This feedback mechanism guides operators to select control values that produce the desired spectral power distribution without exceeding power limitations or creating unbalanced color combinations.

Inventive Principle:
Principle #23Feedback

2Illumination intensity

If operators adjust control values beyond individual channel maximums, then the overall light output is improved, but the system exceeds power limitations

Engineering Contradiction:
Improveoverall light outputVSAvoidpower limitation compliance
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The system dynamically calculates and adjusts the maximum control values for each channel based on the current settings of other channels and the remaining power budget. This allows the system to utilize available power efficiently across multiple channels while ensuring total power consumption remains within limitations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent creates a universal control interface that manages multiple LED channels with different spectral characteristics through a single coordinated system. The dynamic range adjustment mechanism universally applies to all channels, allowing any channel to benefit from power allocated to others, thereby achieving high overall light output while compliance with power limitations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If the user interface provides fixed control ranges for each channel, then the interface simplicity is improved, but the ability to achieve optimal color combinations is reduced

Engineering Contradiction:
Improveinterface simplicityVSAvoidcolor combination flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The user interface displays dynamic control ranges that automatically adjust based on current channel settings. This maintains interface simplicity by presenting clear, actionable control options to operators while adapting to different operating conditions, enabling optimal color combinations without requiring complex manual calculations or adjustments.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs automatic recalculation and adjustment of valid control ranges based on current settings and power availability. This self-service mechanism eliminates the need for operators to manually calculate compatible control values, maintaining interface simplicity while achieving optimal color combinations through automated adaptation.

Inventive Principle:
Principle #25Self-service
