Lighting Device Commissioning by Power-On Time Ordering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting device systems require users to manually reorder and name new devices after addition, which is cumbersome when the devices are mounted in random order, disrupting the user's mental model of their actual installation sequence.
Innovation Solution
A method and system that determine the power-on time of each new lighting device and use this time as a basis for displaying and ordering the devices on a user interface, allowing them to be presented in the order of installation without requiring significant changes to the commissioning device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new lighting devices join the network in random order, then the network can accept devices flexibly, but the user interface displays devices in random order which disrupts the user's mental model and requires manual reordering
Solution Approach 1:
The system records the power-on time of each lighting device before the user interacts with the device list. This preliminary recording of temporal information allows the system to automatically sort devices in the correct installation order later, eliminating the need for manual reordering while preserving network flexibility
2Ease of operation
If the system records and sorts devices by power-on time, then the user interface displays devices in installation order improving usability, but the system complexity increases
Solution Approach 1:
Each lighting device autonomously records its own power-on time using its internal clock when it first joins the network. This self-service approach eliminates the need for a centralized complex sorting system, as each device independently provides the temporal information needed for automatic ordering
Solution Approach 2:
The system changes the ordering parameter from random network assignment to temporal power-on time. By sorting devices based on this temporal parameter, the system achieves intuitive installation order display without requiring complex reordering mechanisms
3Device complexity
If the system uses power-on time as the ordering basis, then the commissioning process becomes simpler and more intuitive, but time synchronization accuracy becomes critical
Solution Approach 1:
The system uses only the relative power-on time information needed for sorting, not absolute precise time synchronization. This partial action approach achieves sufficient ordering accuracy for commissioning purposes without requiring excessive time synchronization precision across all devices

AI summary
A method of commissioning of a number, n, of new lighting devices (10) joining or being added to a network, where n is an integer equal to or larger than 2, where the network comprises at least one bridge device (9) and a commissioning device (30), and where the method comprises determining (101), for each new lighting device (11, 12, 13, 14), at or by the new lighting device (11, 12, 13, 14), a first time, t1, at which the new lighting device (11, 12, 13, 14) is powered on, or a value derived from the first time, t1, obtaining (102), by the commissioning device (30), the first time, t1, or the value derived from the first time, t1, and displaying (103), by the commissioning device (30), on a user interface (4), the new lighting devices (11, 12, 13, 14), wherein the order of the new lighting devices (11, 12, 13, 14) as displayed on the user interface (4) is defined by the first time, t1, or the value derived from the first time, t1, as obtained by the commissioning device (30).
