Solution Overview

Problem

The installation and commissioning of smart lighting systems in buildings are complicated by the need to manually configure device addresses for wireless systems, limiting flexibility and ease of modification, as existing methods require manual note-taking of device addresses and do not efficiently allow for changes or additions over time.

Innovation Solution

A method and system using a portable wireless unit with a display and electronic database to show a graphical building layout, obtain unique device identifiers, and store device locations, enabling easy installation and future modifications by matching identifiers with corresponding locations and updating the database.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual configuration of device addresses is used for wireless systems, then device control functionality is achieved, but installation complexity and time consumption increase significantly

Engineering Contradiction:
Improveinstallation easeVSAvoidcommissioning complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system enables self-service commissioning by allowing devices to automatically generate and assign addresses to themselves through wireless communication with the controller, eliminating the need for manual address configuration by installers. The device independently completes the address assignment process by receiving signals from the controller and storing the assigned address in its memory.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary actions by pre-configuring the controller with the building layout and device locations before installation begins. The controller is prepared with expected device identifiers and locations, enabling it to automatically assign addresses during commissioning without requiring manual intervention for each device.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If manual note-taking of device addresses is required, then device identification is possible, but productivity and installation speed decrease

Engineering Contradiction:
Improveinstallation speedVSAvoidcommissioning time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system replaces the mechanical process of manual note-taking with electronic wireless communication. The controller wirelessly transmits address assignments to devices, and devices automatically receive and store these assignments through wireless receivers, eliminating the need for manual writing and subsequent data entry.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The controller acts as an intermediary between the installer and the wireless devices during commissioning. Instead of the installer directly interacting with each device to configure addresses, the controller mediates the process by automatically assigning addresses based on device identifiers and locations, significantly reducing commissioning time.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If device addresses are manually programmed into controllers, then control functionality is established, but system adaptability for future changes is reduced

Engineering Contradiction:
Improvesystem flexibilityVSAvoidconfiguration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements dynamic address assignment where device addresses are not statically configured but dynamically assigned by the controller based on real-time device identifiers and locations. This dynamic approach allows the system to automatically adapt when devices are added, removed, or relocated, maintaining flexibility without increasing configuration complexity.

Inventive Principle:
Principle #15Dynamics

AI summary

A building commissioning system includes a controller and an electronic database for storing a building layout that includes desired locations for devices to be mounted in a building. The system includes a portable wireless unit with a display for use by an installer. The display on the portable wireless unit shows a graphical representation of the building layout for an area selected by an installer to illustrate desired locations for devices, such as lighting fixtures and wall switches, to be installed in the building. Upon installing a device at the desired location, an installer obtains a unique identifier for the installed device that is matched with the corresponding installed location. The unique identifier and the installed location are sent to the controller for storage in the electronic database. The stored device and location information enable a user to control or adjust device operations.
