Solution Overview

Problem

Existing lighting control systems face difficulties in easily identifying and controlling specific lighting devices among multiple installed devices, leading to inconvenience and complexity, especially for users who cannot easily access or operate traditional switches.

Innovation Solution

A wireless lighting control apparatus that uses tag information to match and register with identification information of lighting devices, allowing for easy control and automatic operation of lighting devices based on received tag information, including determining the operating state and setting positions of lighting devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If identifiers are individually searched and input in lighting devices for network registration, then lighting devices can be registered in the network, but many procedures are necessary and input errors frequently occur

Engineering Contradiction:
Improveregistration accuracyVSAvoidregistration procedure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The lighting device automatically performs network registration by generating and inputting its own identifier without requiring manual user input. The device self-services the registration process by extracting identifier information from the displayed screen and automatically submitting it to the network registration system, thereby eliminating procedural complexity and input errors

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical process of typing identifiers is replaced with an automated optical recognition system. The imaging unit captures the displayed identifier, and image processing algorithms automatically extract and submit the identifier information, substituting the manual input mechanism with an automated vision-based system

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

2Ease of operation

If a user must select one specific lighting device among multiple lighting devices, then the specific device can be controlled, but the time to select one of the lighting devices is increasingly required as the number of lighting devices is increased

Engineering Contradiction:
Improvedevice selectionVSAvoidselection time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

An imaging unit serves as an intermediary between the user and the lighting device selection system. Instead of manually searching through multiple devices, the user simply images the target device with a mobile device, and the system automatically identifies and selects the corresponding lighting device based on the captured identifier information

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The identifier information of the lighting device is copied visually onto a display screen, which can then be captured by an imaging unit. This creates a copyable reference that enables automatic device identification without requiring the user to manually search through device lists or remember device identifiers

Inventive Principle:
Principle #26Copying
