Hybrid Wireless Communicator for High-Speed Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication devices that use low power radio frequency methods like RFID or NFC for direct communication have limited data transfer rates and require close proximity, which restricts their use in transferring large data or meeting time-sensitive requirements, and often need physical contact or connections, leading to power inefficiencies and compatibility issues with various devices.
Innovation Solution
A communication apparatus that combines a short-range wireless RF communicator for inductive coupling and a high-data-rate communicator, allowing direct communication without a network, with the high-data-rate communicator capable of initiating data transfer only when powered by the RF field from another device, enabling efficient data transfer over longer distances and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If low power radio frequency communication (RFID/NFC) is used for direct communication, then power consumption is reduced, but data transfer rate is limited and communication distance is restricted
Solution Approach 1:
The communication apparatus is divided into two distinct communication modules: a low-power RF communicator for initial contact and a high-speed data communicator for bulk data transfer. This segmentation allows each module to operate optimally for its specific function, resolving the contradiction between low power consumption and high data transfer rate.
Solution Approach 2:
The low-power RF communicator acts as an intermediary that initiates communication and establishes a connection before activating the high-speed data communicator. This intermediary approach enables the system to benefit from both low-power initial contact and high-speed data transfer without continuously consuming high power.
2Use of energy by moving object
If low power radio frequency communication (RFID/NFC) is used for direct communication, then power consumption is reduced, but communication distance is limited
Solution Approach 1:
The communication system is segmented into two stages: initial low-power RF communication for device discovery and connection establishment, followed by high-speed communication that can operate over longer distances. This segmentation resolves the contradiction by allowing the system to start with low power consumption and then transition to longer-range communication when needed.
3Productivity
If contact-based communication or wired connections are used, then data transfer rate is high, but physical contact is required and compatibility issues arise
Solution Approach 1:
The patent replaces mechanical contact-based communication systems with wireless communication technologies. The apparatus uses wireless RF communication for initial contact and can establish wireless high-speed data transfer, eliminating the need for physical connectors and improving ease of operation while maintaining high data transfer rates.
Solution Approach 2:
The communication apparatus is designed with multi-functional wireless communication capabilities that can replace various contact-based interfaces (USB, memory card slots, etc.). This universal wireless approach eliminates compatibility issues associated with different physical connectors while maintaining high data transfer performance.
4Productivity
If high data rate communicator is always active, then data transfer capability is ready, but power consumption increases
Solution Approach 1:
The low-power RF communicator performs preliminary actions by establishing initial contact and verifying communication needs before activating the high-speed data communicator. This preliminary action ensures that the high-power component is only activated when necessary, resolving the contradiction between ready data transfer capability and power consumption.
Solution Approach 2:
The communication system dynamically transitions between low-power and high-power modes based on communication requirements. The high-speed data communicator is activated only when data transfer is needed and deactivated when not in use, allowing the system to maintain data transfer capability while minimizing power consumption during idle periods.

AI summary
Communications apparatus has a short range wireless radio frequency communicator (1301a) capable of at least one of seeking to initiate short range communication by transmitting an RF signal and of responding to such initiation so that communication between two short range wireless radio frequency communicators occurs when an antenna of a short range wireless radio frequency communicator seeking to initiate communication by transmitting an RF signal is in range of or comes into range of the antenna of another short range wireless radio frequency communicator responsive to such initiation so that the magnetic field of the RF signal transmitted by the short range wireless radio frequency communicator seeking to initiate communication is inductively coupled to the antenna of the short range wireless radio frequency communicator responsive to such initiation to enable communication of at least one of power and data between the short range wireless radio frequency communicators. The communications apparatus also has a high data rate data communicator (1301b) for communicating directly with another high data rate data communicator to at least one of receive and transmit data when the short range wireless radio frequency communicator (1301a) has communicated with another in-range short range wireless radio frequency communicator.
