Solution Overview
Problem
Current medical communication systems require wired connections between sensors and coordinators, leading to high costs and restricted patient movement due to increased cable requirements, necessitating a wireless communication solution for medical and entertainment services in BAN environments.
Innovation Solution
A communication system utilizing proxy devices for wireless connection between sensors and coordinators, where a wireless communication apparatus acts as a proxy to facilitate data transmission and reception, reducing the need for multiple coordinators and enhancing patient mobility by eliminating wired connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connection is used between sensor and coordinator, then data transmission reliability is improved, but patient mobility is restricted due to cable requirements
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The sensor and coordinator communicate through wireless signals (e.g., radio frequency) instead of physical cables, eliminating the mechanical constraint while maintaining data transmission functionality. This substitution resolves the contradiction by removing the cable that restricts mobility while preserving reliable communication through electromagnetic wave transmission.
2Productivity
If multiple coordinators are provided for each patient, then data collection capability is improved, but system cost increases
Solution Approach 1:
The coordinator is designed with multi-functionality to serve multiple patients simultaneously. A single coordinator can manage and collect data from multiple sensors worn by different patients through wireless communication. This universal design eliminates the need for dedicated coordinators for each patient, maintaining comprehensive data collection capability while reducing the total number of coordinators required, thereby lowering system cost.
3Stability of the object's composition
If wired connection is used between sensor and coordinator, then connection stability is improved, but device complexity increases due to cable management
Solution Approach 1:
The patent replaces the mechanical cable-based connection system with a wireless communication system. Instead of managing physical cables and connectors, the system uses electromagnetic signals for communication between sensors and coordinators. This substitution eliminates the complexity of cable routing, connection management, and physical interface maintenance while providing stable wireless connections through protocol-based communication.

AI summary
Disclosed is a control method of a communication system including at least one sensor that a user wears, a wireless communication apparatus and a coordinator. The control method of the communication system includes: in the coordinator, receiving a proxy authority request for proxy with respect to the at least one sensor and the coordinator from the wireless communication apparatus, and granting the proxy authority to the wireless communication apparatus; in the wireless communication apparatus, creating a user identifier corresponding to the user; in the wireless communication apparatus, searching for the at least one sensor that the user wears, and forming a pairing with the at least one found sensor; in the wireless communication apparatus, making a request to the at least one found sensor for association information for the association with the coordinator and the sensor, and receiving the association information; in the wireless communication apparatus, making a request to the coordinator for association proxy for an association between the at least one found sensor and the coordinator, and receiving the association proxy in response to the request; and in the coordinator, requesting data by forming an association with the at least one found sensor, and receiving data corresponding to the data request.
