Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems using radio communication schemes face challenges in achieving high-capacity data transmission over short distances without interfering with other systems, as they emit unwanted radio waves and require complex settings to select the correct communication partner, and are not suitable for high-speed data transfer due to limitations in signal propagation and orientation.
Innovation Solution
A communication system employing electrostatic or induced electric fields for UWB signal transmission between EFC antennas, using impedance matching units and resonating sections to suppress propagation loss and ensure efficient signal transfer, allowing for high-capacity data communication over very short distances without emitting unnecessary radio waves, thus avoiding interference with other systems.

Engineering Contradiction Analysis
1Ease of operation
If radio communication schemes are used for wireless data transmission, then data can be transmitted without cables, but unwanted radio waves are emitted causing interference with other systems
Solution Approach 1:
The patent changes the fundamental parameter of signal transmission from radiated electromagnetic waves to evanescent electric fields. By using electric-field coupling between facing electrodes instead of traditional antenna radiation, the system achieves cableless data transmission while the evanescent fields attenuate rapidly and do not propagate as unwanted radio waves, thus eliminating interference with other systems.
2Productivity
If traditional antenna systems are used, then radio signals can be transmitted, but complex settings are required to select the correct communication partner
Solution Approach 1:
The patent applies local quality by creating highly localized evanescent electric fields between facing electrodes of adjacent devices. The coupling is strongest when electrodes are directly facing each other at very short distances, providing automatic partner selection based on physical proximity and orientation, thereby eliminating complex access control settings while maintaining high-data-rate transmission capability.
3Productivity
If radio communication is used for high-speed data transfer, then large amounts of data can be transmitted, but signal propagation limitations and orientation requirements restrict usability
Solution Approach 1:
The patent inverts the traditional approach by instead of radiating signals outward from antennas, using evanescent fields that couple directly between facing surfaces of adjacent devices. This inverted coupling mechanism eliminates polarization limitations and provides robust high-speed data transfer that is insensitive to orientation changes, as the electric field coupling maintains effectiveness across a wider range of angular positions compared to traditional directional antenna systems.

AI summary
A communication system includes the following elements: a transmitter including a transmission circuit unit configured to generate an RF signal for transmitting data and an EFC antenna configured to transmit the RF signal as an electrostatic field or an induced electric field; a receiver including an EFC antenna and a reception circuit unit configured to receive and process the RF signal received by the EFC antenna; and an impedance snatching unit configured to make an impedance of the EFC antenna of the transmitter equal to an impedance of the EFC antenna of the receiver. The RF signal is transmitted by electric-field coupling between the EFC antennas, facing each other, of the transmitter and the receiver.
