Solution Overview

Problem

Current lighting fixtures lack the ability to automatically and conveniently adjust their settings based on the presence of mobile devices, requiring manual intervention for users to control light output parameters like intensity and color.

Innovation Solution

A lighting management system with communications circuitry and processing capabilities that detects proximal mobile devices, allowing for automatic adjustments of light output parameters and broadcasting messages to other fixtures or devices, using Bluetooth signals to determine device presence and distance, and implementing settings profiles for desired actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual control of lighting fixtures is used, then user control over light output settings is achieved, but convenience and automation are reduced

Engineering Contradiction:

Improveconvenience of lighting controlVSAvoidautomatic lighting adjustment

Core Design Contradiction:

Ease of operationVSExtent of automation

Solution Approach 1:

The lighting fixture automatically detects mobile devices via Bluetooth communications circuitry and adjusts its own light output parameters based on detected presence, distance, and settings profiles stored in memory, eliminating the need for manual user intervention

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system continuously monitors Bluetooth signal strength from mobile devices and uses this feedback to dynamically adjust lighting parameters, creating a closed-loop control system that responds to user presence and movement

Inventive Principle:

Principle #23Feedback

2Extent of automation

If Bluetooth detection circuitry is added to detect mobile devices, then automatic lighting adjustment capability is improved, but device complexity increases

Engineering Contradiction:

Improveautomatic device presence detectionVSAvoidcommunications circuitry and processing requirements

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The Bluetooth communications circuitry serves multiple functions: detecting mobile device presence, determining distance through signal strength measurement, and triggering appropriate lighting actions based on settings profiles, consolidating what could be separate complex subsystems into a single multi-functional component

AI summary

A lighting management system includes communications circuitry, processing circuitry, and a memory. The memory stores instructions, which, when executed by the processing circuitry cause the lighting management system to receive a message from a lighting fixture via the communications circuitry, the message indicating a proximal presence of a detected mobile device to the lighting fixture, and performing one or more actions in response to receipt of the message. By performing the one or more actions upon receipt of the message as described above, a lighting system may be provided with additional functionality that enhances the lighting system.
