Solution Overview

Problem

The commissioning of networked lighting systems is a labor-intensive and error-prone process that requires manual association of luminaires with switches and sensors, making it inefficient and prone to errors.

Innovation Solution

A lighting system with a sensor system to detect user presence and a controller that operates in a commissioning mode to receive data on luminaire addresses and positional data from a moving actuator, allowing for automatic grouping and association of luminaires, eliminating the need for individual manual switching and association.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual association process is used to commission luminaires, then individual luminaire control can be achieved, but the commissioning process becomes labor intensive and error prone

Engineering Contradiction:

Improvecommissioning accuracyVSAvoidcommissioning effort

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs automatic self-association by detecting which luminaires are switched on during commissioning and automatically grouping them based on sensor activation patterns. The controller autonomously identifies luminaire addresses and creates groups without requiring manual intervention for each individual luminaire association.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical process of individually switching and associating each luminaire is replaced by an automated electronic system that uses sensor detection and digital communication to automatically identify and group luminaires based on their response to switching commands.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If manual commissioning of each luminaire is performed, then precise control can be established, but the process becomes time consuming

Engineering Contradiction:

Improvecommissioning speedVSAvoidcommissioning time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by automatically detecting which luminaires are switched on during the commissioning process and pre-establishing their group associations based on sensor activation patterns, eliminating the need for time-consuming individual luminaire configuration.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Multiple individual luminaire associations are merged into a single automated process that simultaneously identifies and groups multiple luminaires based on their collective response to switching commands and sensor detections, dramatically reducing commissioning time.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A lighting system includes luminaires (L,1, L,2 ) disposed in a space to be illuminated, a sensor system (S1, S2) to detect user presence within the space,and a controller (2) configured in a commissioning mode to receive data corresponding to the addresses of luminaires which are to be defined as a group, and positional data from the sensor system in response to commissioning actuator e.g. a person moving along a path associated with a region of the space associated with the group, and in an operational mode to illuminate the luminaires of the group in response to the sensor system detecting occupancy in the region associated with the group.
