Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If sensor data is collected from various sensors placed in indoor spaces, then the quantity of available data increases, but the effectiveness of service provision deteriorates due to lack of proper utilization methods
Solution Approach 1:
The patent introduces an information processing apparatus as an intermediary between sensor data collection and service provision. This apparatus processes sensor data, generates activity information, and selectively provides it to service providers, thereby enabling effective utilization of the collected data without requiring direct integration between sensors and services
Solution Approach 2:
The system enables self-service by automatically processing sensor data to generate activity information without manual intervention. The information processing apparatus autonomously analyzes sensor inputs, determines user activities, and provides relevant information to appropriate service providers, making the data utilization process automatic and efficient
2Measurement precision
If multiple sensors are deployed to detect user activities and object movements, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The patent merges multiple sensor inputs and processing functions into a single information processing apparatus. This apparatus consolidates the functionality of multiple sensors and processing units, managing all sensor data collection, analysis, and service provision coordination in one integrated system, thereby reducing overall device complexity while maintaining measurement precision
3Adaptability or versatility
If the system processes and analyzes sensor data to generate activity information, then the adaptability to user needs improves, but the processing time and energy consumption increase
Solution Approach 1:
The system performs preliminary actions by continuously monitoring and pre-processing sensor data in the background. The information processing apparatus maintains readiness to quickly generate activity information when needed, having already established baseline data and processing routines, thereby reducing actual processing time when service requests are made

AI summary
An information providing method includes: generating first information indicating that a user has performed a predefined activity when (i) information indicating an activity of the user includes information indicating the predefined activity and (ii) movement of an object corresponding to the predefined activity is detected by a second sensor after a first sensor detects the activity of the user; obtaining, from a second information processing apparatus connected to a first information processing apparatus, information indicating first request content over a network; and when content of the first information is included in the first request content, outputting, to the second information processing apparatus, second information including information for identifying the user or a space, using the first information generated.
