Solution Overview

Problem

Communication between two separate and distinct networks is challenging due to individual security features such as encryption schemes, making direct inter-communication difficult or impossible.

Innovation Solution

A bridge system is created to facilitate communication between incompatible networks by using a bridge component that engages with both networks, identifies and compensates for impedance, voltage, and gain mismatches, and provides protection against overcurrent and overvoltage, ensuring secure and compatible communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If security features such as encryption schemes are implemented in communication networks, then network safety is improved, but compatibility between different networks deteriorates

Engineering Contradiction:
Improvenetwork safetyVSAvoidnetwork compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a bridge device as an intermediary component that connects two incompatible communication networks. The bridge includes a first engagement component that interfaces with the first network and a second engagement component that interfaces with the second network. This mediator translates and adapts signals between the networks, enabling communication while preserving each network's security features and encryption schemes.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The bridge device performs parameter transformations on signals passing between networks. It adjusts signal characteristics such as impedance, voltage levels, and gain to match the requirements of the destination network. The bridge identifies and compensates for parameter mismatches, allowing networks with different technical specifications to communicate effectively.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If a bridge is introduced to enable communication between incompatible networks, then network compatibility is improved, but system complexity increases

Engineering Contradiction:
Improvenetwork compatibilityVSAvoidbridge system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bridge device is designed with multi-functional components that can handle multiple tasks. The engagement components are configured to work with different network types, and the bridge includes integrated functionality for signal translation, parameter adjustment, and protection. This consolidation of functions into a single device reduces overall system complexity compared to using separate components for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The bridge device incorporates automatic identification and compensation mechanisms. The impedance identification component automatically detects impedance mismatches and configures appropriate compensation. Similarly, voltage and gain identification components self-adjust parameters without manual intervention, reducing the operational complexity of the bridge system.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If impedance, voltage, and gain mismatches are compensated for in the bridge, then signal compatibility is improved, but device complexity increases

Engineering Contradiction:
Improvesignal compatibilityVSAvoidbridge component complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bridge device performs parameter compensation in advance before signal transmission. The impedance, voltage, and gain identification components detect mismatches and pre-adjust signal parameters. This preliminary action ensures that signals are properly conditioned before entering the target network, preventing compatibility issues and reducing the need for complex real-time adjustments.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual or mechanical adjustment mechanisms with electronic identification and compensation components. Instead of physical impedance matching networks or manual voltage regulation, the system uses electronic sensors and active circuitry to automatically detect and correct parameter mismatches, reducing mechanical complexity while improving precision.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If protection against overcurrent and overvoltage is implemented, then network safety is improved, but device complexity increases

Engineering Contradiction:
Improvenetwork safetyVSAvoidprotection system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The protection functions for overcurrent and overvoltage are merged into the bridge device itself rather than being implemented as separate protection systems in each network. The current protection component and voltage protection component are integrated into the bridge's engagement components, allowing centralized protection management and reducing overall system complexity while maintaining comprehensive safety.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bridge acts as an intermediary protection layer between the two networks. The current and voltage protection components monitor and limit electrical parameters at the bridge interface, preventing harmful conditions from propagating between networks. This intermediary protection approach provides safety without requiring complex protection mechanisms in each connected network.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Various embodiments that pertain to a bridge between networks. There can be a desire for a first communication network to share messages with a second communication network. However, these networks can individually have their own security measures that make direct network-to-network communication difficult if not impossible. Therefore, a bridge can be created that allows for communication between the networks.
