Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems fail to accommodate individual lighting needs, which vary due to physical conditions, mental conditions, personal preferences, and task-oriented requirements, leading to suboptimal lighting experiences.
Innovation Solution
A light control system (LCS) with a central control engine that adjusts illumination based on individual user profiles, using light sensors to measure actual light exposure and compare it to target profiles, incorporating factors like health, time, and personal preferences to dynamically adjust lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed lighting system is used, then the system structure is simple, but it cannot accommodate individual lighting needs and preferences
Solution Approach 1:
The lighting system transitions from fixed to dynamic control by continuously measuring actual light exposure through sensors and adjusting light source output in real-time based on target light profiles, enabling the system to adapt to individual lighting needs while maintaining manageable complexity through automated control
Solution Approach 2:
The system implements feedback control by measuring actual light exposure with sensors, comparing it against target light profiles stored in memory, and automatically adjusting light source intensity to minimize the difference between actual and target exposure, thereby achieving adaptability without requiring complex manual intervention
2Reliability
If continuous light measurement and adjustment is implemented, then individual lighting needs are met, but energy consumption increases
Solution Approach 1:
The lighting system operates autonomously by automatically measuring light exposure, comparing it to target profiles, and adjusting illumination without human intervention, thereby maintaining high lighting accuracy while reducing energy consumption by eliminating the need for continuous manual monitoring and adjustment
3Area of stationary object
If multiple sensors and light sources are distributed throughout the environment, then lighting coverage is improved, but system complexity increases
Solution Approach 1:
The system achieves broad lighting coverage through multiple distributed sensors and light sources that can serve multiple functions: sensors both detect ambient light and track individual positions, while light sources provide both illumination and serve as identifiable targets for sensor calibration, thereby expanding coverage without proportionally increasing system complexity
