Proximity Communication Relay for Remote Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Proximity communication systems, such as NFC, require devices to be in close proximity, limiting the ability to control or operate stationary devices from a remote location.
Innovation Solution
A system comprising a mobile terminal device with a proximity communication section, a charger with high-speed communication capabilities, and a control section that authenticates the device and relays communication between the mobile terminal device and a stationary device, allowing remote operation through high-speed communication.

Engineering Contradiction Analysis
1Reliability
If proximity communication is used for one-to-one communication between devices, then communication reliability is improved, but the requirement for devices to be in close proximity (0-10 cm) limits operational flexibility
Solution Approach 1:
The stationary device acts as an intermediary between the mobile terminal device and the target device. The mobile terminal device establishes proximity communication with the stationary device, which then relays commands to the target device via wireless communication (Bluetooth, Wi-Fi). This mediator approach allows the mobile device to control the target device remotely without requiring direct proximity to it.
Solution Approach 2:
The system transitions from direct one-to-one proximity communication to a multi-dimensional communication architecture. The stationary device introduces an additional dimension in the communication topology, enabling indirect communication paths that extend beyond the limited proximity range while maintaining secure authentication.
2Reliability
If direct proximity communication is used between mobile terminal device and stationary device, then communication security is improved, but the communication distance is limited to very close proximity
Solution Approach 1:
The stationary device serves as a secure intermediary that maintains authentication credentials. It establishes secure proximity communication with the mobile terminal device, then uses separate wireless communication channels to reach the target device. This architecture extends communication distance while preserving security through the intermediary's authentication mechanism.
Solution Approach 2:
The communication system is segmented into two distinct communication paths: a secure proximity communication path between the mobile terminal device and stationary device for authentication, and a separate wireless communication path from the stationary device to the target device for command execution. This segmentation allows each path to be optimized for its specific function.

AI summary
A proximity communication system includes: a first device (mobile terminal device) including a first proximity communication section performing proximity communication; a second device (stationary device) including a first high-speed communication section performing high-speed communication faster than the proximity communication; and a third device (charger) including: a second proximity communication section performing proximity communication; a second high-speed communication section performing high-speed communication; a storage section in which authentication information for authenticating the first device is stored; and a control section authenticating the first device by using the authentication information when the second proximity communication section starts communication with the first device and relaying communication between the first device and the second device by using the second proximity communication section and the second high-speed communication section in a case that the authentication is successful.
