Solution Overview

Problem

Current network-based lighting control systems require a special communications bridge or gateway device to bridge between local and wide area networks, which poses challenges such as difficulty in finding deployment space, high installation and maintenance costs, and interference with existing structures, due to their need for a separate LAN and WAN interface.

Innovation Solution

A photo controller equipped with both LAN and WAN interfaces, allowing direct communication between lighting devices and the wide area network without the need for a special communications bridge or gateway, providing a plug-and-play solution that eliminates the need for additional equipment and reduces installation complexities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a special communications bridge or gateway device is deployed to bridge between LAN and WAN, then WAN communication capability is achieved, but deployment space requirements and installation complexity increase

Engineering Contradiction:
ImproveWAN communication capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the LAN interface and WAN interface into a single lighting controller device. The controller integrates both communication capabilities, eliminating the need for separate gateway equipment. This merging of functions directly resolves the technical contradiction by achieving WAN communication capability while reducing system complexity and eliminating additional deployment space requirements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lighting controller is designed with multi-functionality, serving both as a local control device with LAN capability and as a WAN-connected device. By incorporating both LAN and WAN interfaces in one device, the controller becomes a universal communication node that can perform multiple functions without requiring specialized gateway equipment, thus reducing overall system complexity.

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

2Reliability

If a separate communications bridge is installed near lighting devices, then network connectivity is improved, but real estate availability and installation costs worsen

Engineering Contradiction:
Improvenetwork connectivityVSAvoidinstallation cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent merges the communications bridge functionality directly into the lighting controller housing. By integrating the WAN interface and communication capabilities within the existing lighting controller, the system eliminates the need for separate gateway设备安装, thereby reducing installation costs and eliminating real estate availability constraints while maintaining reliable network connectivity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lighting controller serves itself by providing both LAN and WAN communication capabilities within the same device. This self-service approach eliminates the need for external gateway equipment and reduces installation complexity, making the system easier to deploy without requiring additional real estate or specialized installation procedures.

Inventive Principle:
Principle #25Self-service

3Speed

If pole-mounted gateway equipment is attached to existing structures, then communication range is extended, but structural integrity and safety worsen

Engineering Contradiction:
Improvecommunication rangeVSAvoidstructural hazard
Core Design Contradiction:
SpeedVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the communication gateway functionality from external pole-mounted equipment and relocates it within the lighting controller itself. This extraction eliminates the need to attach additional equipment to existing structures, thereby removing the structural hazards and safety concerns associated with pole-mounted gateways while maintaining the required communication range through integrated wireless interfaces.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

By merging the gateway communication functions within the existing lighting controller housing, the patent eliminates the need for separate pole-mounted equipment. This integration approach removes all structural hazards associated with attaching additional equipment to existing poles or structures, while the wireless communication interfaces maintain the necessary communication range.

Inventive Principle:
Principle #5Merging (Combining)
