Multi-User Lighting Control via Activity-Based Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lighting control systems fail to adequately address the diverse lighting preferences of multiple users in a room, particularly varying based on activity, and often prioritize one user's preferences over others.
Innovation Solution
A system comprising a processor, communication interface, and storage that identifies users and their activities to adjust light output from multiple light output apparatuses based on individual lighting preferences, using data tables and algorithms to transmit commands for customized lighting settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current lighting control systems adjust light based on one user's preference, then that user's lighting preference is satisfied, but other users' lighting preferences are not addressed
Solution Approach 1:
The patent divides the lighting control into multiple independent zones, each with its own light output apparatus controlled by a specific user. The system segments the user base into individual users with distinct preferences and locations, allowing each user to independently control their designated lighting zone without affecting others.
Solution Approach 2:
The patent implements local quality by allowing different lighting characteristics (intensity, color temperature, timing) in different spatial zones corresponding to different users. Each user's lighting environment is customized to their local preferences and activity needs, creating heterogeneous lighting conditions across the shared space.
2Adaptability or versatility
If lighting control systems use simple on/off or dimming control, then the system is easy to operate, but it cannot address varying lighting preferences based on activity
Solution Approach 1:
The system automatically detects user activity states and adjusts lighting parameters without requiring manual user input. Sensors and processors monitor user presence, activity type, and environmental conditions, then autonomously configure appropriate lighting settings based on pre-programmed preferences and activity profiles.
Solution Approach 2:
The lighting control system transitions from static on/off or simple dimming to dynamic, multi-parameter control that continuously adapts to changing user activities. The system adjusts multiple lighting attributes (intensity, color temperature, timing) in real-time based on detected activity states, creating a responsive and adaptive lighting environment.
3Adaptability or versatility
If multiple light output apparatuses are controlled independently for each user, then individual lighting preferences are met, but the control system complexity increases
Solution Approach 1:
The patent segments the control system into independent modules, each managing a specific user's lighting preferences and a designated zone's light output apparatus. This modular architecture allows each segment to operate autonomously based on its assigned user's preferences, reducing the complexity burden on the central system while maintaining comprehensive multi-user customization.
4Measurement precision
If the system monitors and responds to user activities in real-time, then lighting preferences are accurately addressed, but energy consumption and system complexity increase
Solution Approach 1:
The system employs periodic monitoring and sampling of user activities rather than continuous real-time monitoring. Sensors detect user presence and activity states at scheduled intervals, and the lighting system updates settings based on these periodic measurements, reducing energy consumption while maintaining sufficient accuracy for effective lighting control.
Data Source
AI summary
In one aspect, a device includes a processor, a communication interface accessible to the processor, and storage accessible to the processor. The storage bears instructions executable by the processor to identify an activity associated with a user. The instructions are also executable by the processor to use the communication interface to transmit at least one command to a light output apparatus to adjust light from the light output apparatus based on the identified activity.
