Solution Overview

Problem

Existing data communication systems in electronic devices face challenges in efficiently transmitting high-speed data and power supply configuration data, often requiring separate communication links which can be unreliable and bulky.

Innovation Solution

The implementation of a data communication circuit that combines high-speed data (such as USB 3.0) and power supply configuration data into a single serial data stream, allowing for efficient transmission via a single communication link, such as a wireless channel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate communication links are used for high-speed data and power supply configuration data, then data transmission reliability is improved, but device complexity and connection bulk increase

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidconnection complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines high-speed data and power supply configuration data into a single serial communication link. The data communication circuit multiplexes these different data types over one physical connection, eliminating the need for separate connectors and reducing overall system complexity while maintaining reliable transmission of both data types.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single communication link is designed to handle multiple functions simultaneously - transmitting both high-speed data and power supply configuration data. This multi-functional approach allows one connection to replace what would traditionally require multiple specialized links, reducing device complexity without sacrificing reliability.

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

2Reliability

If separate communication links are used for high-speed data and power supply configuration data, then data transmission reliability is improved, but device size increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoiddevice volume
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

By merging high-speed data and power supply configuration data into a single serial link, the patent reduces the physical space required for connectors and connection infrastructure. This consolidation allows for thinner device designs while maintaining connection reliability through proper signal integrity management.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If a single serial communication link is used for both high-speed data and power supply configuration data, then device complexity is reduced, but data transmission reliability may worsen

Engineering Contradiction:
Improveconnection complexityVSAvoiddata transmission reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The data communication circuit segments and multiplexes different data types (high-speed data and power supply configuration data) into a structured serial format. This segmentation allows proper timing and protocol management for each data type while transmitting them over a single link, maintaining reliability through organized data separation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The data communication circuit acts as an intermediary that manages the multiplexing and demultiplexing of different data types. It provides protocol control and signal management to ensure that high-speed data and power supply configuration data are properly separated and transmitted without interference, maintaining reliability despite using a single link.

Inventive Principle:
Principle #24Intermediary (Mediator)
