Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waveguide systems face challenges in increasing data transfer speeds beyond 14.4 Gbits/sec to 28.8 Gbits/sec, 56 Gbits/sec, and 112 Gbits/sec while maintaining signal integrity, which is a complex task due to the need for efficient signal propagation and modulation techniques.
Innovation Solution
The proposed data communication system employs waveguides and signal modulators to convert TEM signals to non-TEM signals, which are then propagated through waveguides and an electrical connector, using phase shifting and common waveguides to maintain signal integrity and achieve higher data transfer rates, with the system including amplifiers and filters to ensure signal quality.

Engineering Contradiction Analysis
1Speed
If waveguide systems use conventional signal transmission methods, then data transfer speeds are limited to 14.4 Gbits/sec, but increasing data transfer speeds to 28.8 Gbits/sec, 56 Gbits/sec, and 112 Gbits/sec causes signal integrity degradation
Solution Approach 1:
The patent replaces conventional electrical signal transmission with waveguide-based electromagnetic wave propagation. This substitution enables higher data transfer speeds (28.8, 56, and 112 Gbits/sec) while maintaining signal integrity through the use of waveguides that guide electromagnetic waves, avoiding the signal degradation issues inherent in conventional electrical transmission systems.
Solution Approach 2:
The patent employs phase shifting techniques and modulation methods to encode data in the electromagnetic waves transmitted through waveguides. By changing parameters such as phase, frequency, and amplitude of the electromagnetic waves, the system achieves higher data transfer rates while maintaining signal integrity through sophisticated signal processing and error correction mechanisms.
2Productivity
If waveguide systems increase data transfer speeds beyond conventional limits, then higher data rates are achieved, but the complexity of maintaining signal integrity increases significantly
Solution Approach 1:
The patent divides the waveguide system into multiple independent waveguides, each capable of carrying separate electromagnetic wave signals. This segmentation allows parallel data transmission at high rates while simplifying the signal processing for each individual waveguide, as each can be independently optimized and managed without interfering with others.
Solution Approach 2:
The patent designs the waveguide system to support multiple data transfer rates (14.4, 28.8, 56, and 112 Gbits/sec) using the same physical infrastructure. The waveguides and associated signal processing equipment are configured to adaptively adjust operating parameters to achieve different data rates, reducing overall system complexity compared to having separate systems for each rate.

The system effectively increases data transfer speeds while maintaining signal integrity, achieving error rates of no more than 1 error per 10^4 to 10^5 bits, and supports multiple data transfer speeds by using a common carrier frequency and optimized waveguide geometry.
Implementation Method 1
each of the waveguide channels is defined by an internal surface that comprises an electrically conductive and reflective waveguide material, such that the waveguide channels are configured to propagate electrical signals from one of the first and second surfaces to the other of the first and second surfaces
