Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard lighting systems use indirect light measurement with sensors attached to light sources, then the system can regulate light control, but it cannot accurately measure photometric parameters such as irradiance, color temperature, and color composition to adjust lighting according to physiological needs
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the light source and the measurement system. This mobile device captures images of the light source and uses image processing to determine photometric parameters, serving as a mediator that bridges the gap between simple light control and precise physiological-based lighting adjustment
Solution Approach 2:
The patent replaces the mechanical sensor attachment system with an optical imaging system. Instead of physically attaching sensors to light sources, the system uses a mobile device with camera to capture images and process them to extract photometric parameters, substituting mechanical measurement with optical detection and computational analysis
2Adaptability or versatility
If the system uses indirect light measurement principle with reflected light from surfaces, then the system can control lighting, but it cannot account for surface reflective properties that significantly influence human perception
Solution Approach 1:
The patent performs preliminary measurement of the light source itself before it interacts with surfaces. By capturing images directly of the light source and determining its photometric parameters beforehand, the system preserves information about the light's intrinsic properties before surface reflection modifies them
Solution Approach 2:
The patent creates an optical copy of the light source by capturing its image with a camera. This optical copy preserves the light source's photometric characteristics without being affected by surface reflections, allowing the system to analyze and control lighting based on the original light properties rather than reflected light
3Ease of operation
If the system requires assignment of positions to lighting devices, then the system can control specific luminaires, but the addressing process becomes problematic and complex
Solution Approach 1:
The patent enables the mobile device to automatically detect and identify light sources through image capture and processing. The system performs self-service by automatically determining which light source is being measured and obtaining its identification information, eliminating the need for manual addressing or complex position assignment procedures
Solution Approach 2:
The patent utilizes the light source's own light output, including its color characteristics, as part of the identification and detection process. By analyzing the light's photometric properties and temporal patterns, the system can identify and address specific luminaires without requiring separate addressing mechanisms
