Solution Overview
Problem
Air conditioning devices that utilize image sensors to analyze indoor environments for personalized comfort face challenges in protecting user privacy and efficiently managing energy consumption based on detected objects and activities.
Innovation Solution
An air conditioning device equipped with an image sensor and a processor that identifies objects using edge information from images, controlling operations such as air conditioning modes and power consumption based on the type and activity level of detected objects, while minimizing privacy concerns by using binary images with only contour lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If full-color images are captured to accurately identify objects and their states, then object recognition accuracy is improved, but user privacy is compromised
Solution Approach 1:
The patent extracts only the essential edge information from images while discarding color and texture data that could identify individuals. This is achieved through edge detection algorithms that capture only contour lines and boundary information, sufficient for object classification but inadequate for personal identification, thus resolving the privacy-accuracy contradiction
Solution Approach 2:
Instead of using original images that contain personal information, the patent creates a simplified copy containing only edge information. This copied representation maintains the structural features needed for object recognition while removing identifying characteristics, allowing accurate classification without privacy risks
2Ease of operation
If air conditioning operations are continuously adjusted based on real-time object detection, then indoor comfort is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic object detection and air conditioning adjustment rather than continuous operation. The system detects objects at intervals and adjusts air conditioning parameters based on detected states, maintaining comfort while reducing processing load and power consumption compared to continuous real-time adjustment
Solution Approach 2:
The air conditioning system automatically adjusts its operation based on detected object states without requiring continuous user input or monitoring. Once objects are detected and classified, the system autonomously modifies air conditioning parameters and maintains these settings until detection intervals reveal changed conditions, reducing overall system activity and energy usage
