Solution Overview

Problem

Existing wireless lighting control systems face issues with identifier overlap, where setting an identifier for a target lighting device can inadvertently register and control adjacent devices due to their proximity, leading to unintended control of multiple lighting devices in close proximity.

Innovation Solution

A lighting control system that registers lighting devices based on received signal strengths, allowing for the selection of a reference device and subsequent registration of other devices, ensuring precise control and avoiding simultaneous registration of adjacent devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless signal is transmitted to set identifier in target lighting device, then lighting device can be controlled wirelessly, but adjacent lighting devices within transmission range are also affected and may be incorrectly registered

Engineering Contradiction:
Improvewireless control capabilityVSAvoididentifier setting accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies local quality by making the registration process location-specific through signal strength measurement. The wireless transmitter registers only the lighting device with the strongest signal (closest proximity), while ignoring other devices within transmission range. This creates a localized registration effect that prevents adjacent devices from being incorrectly registered, resolving the contradiction between wireless control ease and registration accuracy.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If identifier is set through wireless transmitter at predetermined home, then target lighting device can be controlled, but lighting devices at adjacent homes are also changed into registration setting mode

Engineering Contradiction:
Improvewireless transmission rangeVSAvoidunintended device registration
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements feedback by measuring the signal strength received from each lighting device and using this information to determine which device should be registered. The wireless transmitter compares signal strengths and selectively registers only the device with the strongest signal, providing a feedback mechanism that prevents unintended registration of adjacent home devices while maintaining versatile wireless transmission capability.

Inventive Principle:
Principle #23Feedback
