Solution Overview

Problem

Conventional solid state light source-based luminaires and fixtures face difficulties in changing technical and end-user parameters, as these are either hardcoded in firmware or hardwired into circuitry, making it cumbersome and expensive to adjust or replace power supplies for different configurations.

Innovation Solution

The system allows for remote configuration of lighting power supplies by enabling a receiver connected to a memory system, receiving and decoding configuration signals to adjust parameters such as intensity and dimming rates, reducing the need for multiple power supply versions and simplifying setup processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If parameters are hardcoded in embedded firmware or hardwired into circuitry, then device reliability is improved, but adaptability deteriorates

Engineering Contradiction:

Improveparameter stabilityVSAvoidparameter configurability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic parameter configuration by allowing the power supply to receive configuration signals wirelessly via a receiver module. This enables parameters to change from static (hardcoded/hardwired) to dynamic (remotely adjustable), resolving the contradiction between reliability and adaptability while maintaining system stability through controlled parameter updates.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces a receiver module as an intermediary component between the power supply and external configuration systems. This intermediary enables parameter changes without direct physical modification of the power supply circuitry, allowing adaptability while preserving the reliability of the core power supply functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If firmware is changed and re-programmed to change parameters, then adaptability is improved, but loss of time increases

Engineering Contradiction:

Improveparameter adjustabilityVSAvoidsetup time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical/time-consuming process of firmware re-programming and physical component changes with a wireless configuration system. The receiver module receives configuration signals that instantly adjust parameters without requiring time-consuming firmware updates or physical intervention, significantly reducing setup time while maintaining adaptability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If power supply components are changed or power supply is exchanged, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improveparameter customizationVSAvoidpower supply configuration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal receiver module that can receive different configuration signals for various parameters without requiring different physical power supply units. This single receiver module handles multiple parameter types (intensity, dimming rates, pulse width modulation), eliminating the need for multiple specialized power supply versions and reducing overall system complexity while maintaining high adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Systems, methods, and computer program products for remote configuration of one or more power supplies, particularly lighting power supplies, are disclosed. A configuration signal that includes a setting for a parameter is generated and then transmitted to a power supply. The power supply decodes the configuration signal and, if one or more certain conditions are met, configures the power supply according to information provided in the configuration signal.
