Solution Overview

Problem

The existing lighting control systems for multiple rooms are costly to install due to the need for extensive configuration of gateways for wireless communication in large office settings, where each room's sub-system must be individually connected to a local wireless network.

Innovation Solution

A lighting control system with a first sub-system containing a control unit and a gateway module that communicates with both local area networks and other sub-systems via dual personal area networks, eliminating the need for separate gateway modules in each sub-system by using a single gateway module to connect multiple sub-systems to a local area network, utilizing ZigBee protocol for low-power and secure communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If each sub-system is connected to a local wireless network through a separate gateway, then communication between sub-systems is reliable, but installation cost and complexity increase significantly

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple sub-systems share a common gateway module instead of each having its own gateway. The gateway module serves as a shared communication interface between multiple control units and the local area network, reducing the total number of gateways needed and simplifying installation while maintaining communication reliability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The gateway module is designed to serve multiple sub-systems simultaneously, performing universal communication functions for all connected control units. This multi-functional gateway can handle communications from different sub-systems through standardized protocols, eliminating the need for dedicated gateways.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Area of stationary object

If each sub-system has its own gateway module for wireless communication, then network coverage is comprehensive, but hardware cost increases

Engineering Contradiction:
Improvenetwork coverage areaVSAvoidnumber of gateway modules
Core Design Contradiction:
Area of stationary objectVSQuantity of substance

Solution Approach 1:

Multiple sub-systems share a common gateway module instead of each having its own gateway. The gateway module serves as a shared communication interface between multiple control units and the local area network, reducing the total number of gateways needed and simplifying installation while maintaining communication reliability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The gateway module acts as an intermediary between multiple control units and the local area network. It mediates communication between different sub-systems and the network infrastructure, allowing comprehensive network coverage without requiring proportional numbers of gateway modules.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If configuration work for each gateway is extensive, then network stability is improved, but installation time increases

Engineering Contradiction:
Improvenetwork stabilityVSAvoidinstallation time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The gateway module is pre-configured with standardized communication protocols and settings before deployment. This preliminary configuration allows multiple control units to connect using standard procedures without requiring extensive individual configuration work, reducing installation time while maintaining network stability through proven configurations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses standardized communication parameters and protocols that can be applied uniformly across multiple sub-systems. By changing from custom configurations to standardized parameters, the installation process becomes faster while network stability is maintained through established communication standards.

Inventive Principle:
Principle #35Parameter changes
