Solution Overview

Problem

Existing LED control systems face challenges in efficiently managing computing resources when individually controlling a large number of LEDs in a formation, particularly in high-resolution and low-resolution lighting scenarios, leading to inefficiencies in resource utilization.

Innovation Solution

A controller is configured to operate in two modes: a first mode for individual LED control requiring high computing resources for high-resolution outputs and a second mode for controlling LED clusters as units, using a slower interface to conserve resources for low-resolution outputs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the controller individually controls each LED to produce high-resolution output, then the resolution and detail of the message output is improved, but the computing resources required increase significantly

Engineering Contradiction:
ImproveresolutionVSAvoidcomputing resources
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The LED array is divided into multiple LED clusters, where each cluster contains multiple LEDs that can be controlled together as a unit. This segmentation allows the system to switch between two control modes: individual LED control for high-resolution output and cluster-level control for lower-resolution output, thereby resolving the contradiction between resolution and computing resource consumption.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the controller individually controls each LED, then the variety and detail of messages that can be output is improved, but the computational demands and resource utilization increase

Engineering Contradiction:
Improvemessage varietyVSAvoidcomputational demands
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically switches between two control modes based on the requirements of the message being displayed. When high message variety and detail are needed, the system uses individual LED control mode. When resource conservation is prioritized, it switches to LED cluster control mode. This dynamic adaptability resolves the contradiction between message variety and computational complexity.

Principle #15Dynamics

3Speed

If the controller uses a fast interface to individually control each LED, then the control precision and response time are improved, but the resource consumption increases

Engineering Contradiction:
Improvecontrol response timeVSAvoidresource consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The system changes the control parameter granularity based on operational requirements. In individual LED control mode, the controller uses fine-grained parameters to control each LED individually, achieving high precision and fast response. In LED cluster control mode, it uses coarser-grained parameters to control groups of LEDs, reducing resource consumption. This parameter change strategy resolves the contradiction between control speed and resource consumption.

AI summary

A system includes a light-emitting diode (LED) circuit comprising a set of LEDs arranged in a formation, wherein the set of LEDs comprise a set of LED clusters; and a controller. The controller is configured to: control, according to a first LED control mode, whether each LED of the set of LEDs is turned on or turned off; and control, according to a second LED control mode, whether each LED cluster of the set of LED clusters is turned on or turned off, wherein the first LED control mode requires the controller to use a first amount of computing resources, wherein the second LED control mode requires the controller to use a second amount of computing resources, and wherein the second amount of computing resources is lower than the first amount of computing resources.
