Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waveguide systems face challenges in increasing data transfer speeds while maintaining signal integrity, particularly in transitioning between different data rates such as from 14.4 Gbits/sec to 28.8 Gbits/sec, 56 Gbits/sec, and 112 Gbits/sec.
Innovation Solution
The proposed solution involves a waveguide-based data communication system that includes a first and second substrate with electrical connectors configured to connect waveguides between mating and mounting interfaces. This system uses signal modulators to convert TEM signals to non-TEM signals, which are then propagated through waveguides and electrical connectors to maintain signal integrity across different data transfer speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If waveguide systems use traditional electrical connectors to increase data transfer speeds, then data transfer speed is improved, but signal integrity deteriorates at higher rates
Solution Approach 1:
The patent replaces traditional electrical connectors with waveguide-based connectors that transmit signals as electromagnetic waves rather than electrical currents. This substitution eliminates the signal integrity issues associated with high-speed electrical connections while maintaining mechanical connectivity between substrates.
Solution Approach 2:
The patent changes the signal transmission parameter from electrical current (TEM mode in traditional connectors) to electromagnetic wave propagation (waveguide modes). This parameter change enables higher data transfer speeds while preserving signal integrity through the waveguide structure's inherent shielding and controlled impedance characteristics.
2Adaptability or versatility
If waveguide systems transition between different data rates, then adaptability is improved, but system complexity increases
Solution Approach 1:
The waveguide connector design incorporates multi-functionality by enabling operation across multiple data rates (14.4 Gbits/sec, 28.8 Gbits/sec, 56 Gbits/sec, 112 Gbits/sec) through a single unified structure. The waveguide geometry and electrical connector configuration work together to provide adaptive signal transmission without requiring separate hardware for each data rate.
