Lighting Control Apparatus for Dynamic User State Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connected lighting systems struggle to accommodate varying lighting preferences and physiological or cognitive states of multiple users within a shared space, often leading to conflicting lighting conditions and neglecting the needs of new users without predefined preferences.
Innovation Solution
A lighting control apparatus that receives light control input data and physiological or cognitive state data from users to generate control signals for light emitting devices, allowing for dynamic adjustment of lighting conditions to suit individual needs, including automatic adaptation for new users detected by monitoring devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system accepts multiple light control inputs from multiple users to provide diverse lighting conditions, then the lighting versatility is improved, but the likelihood of contradictory user preferences increases
Solution Approach 1:
The system introduces a central lighting control apparatus that acts as an intermediary between multiple users and the light emitting devices. This mediator receives inputs from multiple users, processes their preferences through an inference engine, and generates compromise control signals that balance conflicting requirements, thereby managing preference conflicts without reducing lighting versatility
Solution Approach 2:
The system dynamically changes lighting parameters (intensity, color temperature, timing) based on aggregated user preferences and contextual information. By adjusting these parameters in response to multiple inputs, the system resolves contradictions through quantitative modification rather than qualitative compromise
2Measurement precision
If the system requires predefined personal preferences for each user to control lighting, then the lighting control accuracy is improved, but new users without predefined preferences are neglected
Solution Approach 1:
The system performs preliminary actions by detecting new users through sensors (motion detectors, cameras, RFID readers) before they provide any input data. Upon detection, the system automatically generates default lighting conditions suitable for the detected context (e.g., dimming lights when motion is detected in a bedroom at night), allowing new users to experience personalized lighting immediately without manual preference setup
Solution Approach 2:
The system enables new users to receive personalized lighting control through self-service mechanisms. By automatically detecting user presence and inferring preferences from contextual data (time of day, location, activity patterns), the system serves new users without requiring their active participation in preference definition, thus maintaining accuracy while accommodating newcomers
