Solution Overview

Problem

Existing lighting control systems face issues with synchronization and status indication of electrical loads, leading to confusion and inefficiency in controlling groups of lighting devices and other electrical loads.

Innovation Solution

A remote control device with a status indicator and actuation/rotation portions that provides synchronized control and feedback through wireless signals, ensuring devices are in sync and providing clear status indicators for intensity levels and commands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a common lighting control device controls a group of lighting devices, then the lighting devices can be controlled collectively, but some lighting devices may become out of sync with the rest of the group

Engineering Contradiction:
Improvecollective control capabilityVSAvoidsynchronization status
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the control device receives status information from each lighting device in the group. The status indicator displays the operational status of each device, allowing the system to detect when devices are out of sync and providing visual feedback to users about the synchronization state of the group.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent segments the group control into individual device status monitoring. Instead of treating the group as a single unit, the system monitors and displays the status of each lighting device separately, enabling identification and correction of synchronization issues in individual devices within the group.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If different types of electrical loads are controlled by a single control device, then the control device can manage multiple loads, but the status of these loads may not be easily determined from a single status indicator

Engineering Contradiction:
Improvemulti-load control capabilityVSAvoidstatus indication clarity
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies local quality by providing differentiated status indication methods for different types of electrical loads. The system uses a plurality of light sources with different characteristics (color, intensity, pattern) to represent different load types and their statuses, allowing users to easily distinguish between various loads and their operational states.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent utilizes color changes in the status indicator to convey different load statuses. Different colors or color combinations represent different types of electrical loads and their operational states, enabling users to quickly identify and understand the status of multiple diverse loads through visual color cues.

Inventive Principle:
Principle #32Color changes

AI summary

The remote control device may provide feedback via the status indicator that indicates the present intensity level of a lighting device responsive to the remote control device. The remote control device may provide feedback to indicate a first present intensity level of a first lighting device when the command is a first command type, and a second present intensity level of a second lighting device when the command is a second command type. When the first command type is a raise command and the second command type is a lower command, the first present intensity level may be less than the second present intensity level. In addition, the first lighting device may be a lighting device responsive to the remote control device with a lowest present intensity level and the second lighting device may be a lighting device responsive to the remote control device with a highest present intensity level.
