Solution Overview
Problem
The existing systems for managing excrement data in nursing homes require significant data communication to cloud servers, leading to increased data transmission loads and costs, as they rely on cloud servers with abundant resources for analysis, which is inefficient and costly.
Innovation Solution
An excrement management system that employs an edge server to analyze and filter data locally before transmitting only necessary information to the cloud server, using a combination of light emitting and receiving units, communication devices, and user identification mechanisms to reduce data communication and ensure secure transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all image data photographed by the image photographing unit is transmitted to the cloud server, then the cloud server can perform comprehensive analysis of excrement characteristics, but the data communication amount is largely increased
Solution Approach 1:
The patent divides the data processing system into two segments: an edge server that performs preliminary filtering and basic analysis locally, and a cloud server that receives only selected data for comprehensive analysis. This segmentation allows the system to maintain high analysis accuracy while reducing the volume of data transmitted over the network.
Solution Approach 2:
The edge server performs preliminary actions by analyzing image data locally before transmission to the cloud server. It filters and pre-processes the data, performing initial excrement characteristic analysis and selecting only relevant data for cloud server processing. This preliminary action reduces the data communication amount while ensuring that the cloud server receives data suitable for comprehensive analysis.
2Measurement precision
If a cloud server with abundant calculation resources is used for analysis, then comprehensive excrement characteristic analysis can be performed, but communication utility charge is increased
Solution Approach 1:
The edge server performs preliminary analysis and filtering of image data before transmission to the cloud server. By pre-processing data locally and selecting only relevant information for cloud server analysis, the system reduces the volume of transmitted data, thereby lowering communication utility charges while maintaining the cloud server's comprehensive analysis capability for receiving data.
Solution Approach 2:
The edge server acts as an intermediary between the image photographing unit and the cloud server. It receives image data, performs local processing and filtering, and then transmits only selected data to the cloud server. This intermediary role reduces communication costs by minimizing data transmission while preserving the cloud server's analytical capabilities.
3Measurement precision
If image data is transmitted over wide-area network to cloud server, then comprehensive analysis can be performed, but communication utility charge increases
Solution Approach 1:
The edge server performs preliminary analysis and filtering of image data before transmission to the cloud server. By pre-processing data locally and selecting only relevant information for cloud server analysis, the system reduces the volume of data transmitted over the wide-area network, thereby lowering communication utility charges while maintaining the cloud server's comprehensive analysis capability for receiving data.
Solution Approach 2:
The patent divides the data processing system into two segments: an edge server that performs preliminary filtering and basic analysis locally, and a cloud server that receives only selected data for comprehensive analysis. This segmentation allows the system to maintain high analysis accuracy while reducing the volume of data transmitted over the network.

AI summary
An excrement management system according to an embodiment includes: a closet bowl in which a bowl part for receiving excrement is formed; a light emitting unit configured to emit light toward an inner part of the closet bowl; a light receiving unit comprising an image sensor configured to receive light; a cloud server and an edge server configured to analyze light reception data received by the light receiving unit; a first communication device configured to transmit the light reception data to the cloud server; and a second communication device configured to transmit the light reception data to the edge server. The cloud server analyzes the light reception data to determine a characteristic of excrement, and the edge server analyzes the light reception data to determine whether to transmit the light reception data to the cloud server by the first communication device.
