Solution Overview

Problem

Portable electronic devices face challenges in providing multiple interfaces in a compact form, making it cumbersome to connect and mount various peripheral devices due to the need for multiple connectors, which increases in size or number when multiple interfaces are required.

Innovation Solution

A portable electronic device equipped with a device controller and a crossbar switch that simultaneously establishes data channels for both external and network interfaces within a single receptacle, allowing for the switching between these interfaces to consolidate multiple connections in a single connector.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple connectors are provided in the chassis to support multiple interfaces, then the number of available interfaces increases, but the device size and complexity increase

Engineering Contradiction:
Improvenumber of interfacesVSAvoidconnector quantity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal connector design where a single receptacle can establish multiple types of data channels (USB 2.0, USB 3.0, DisplayPort, Ethernet) by dynamically configuring the crossbar switch. This multi-functional approach allows one connector to replace what would traditionally require multiple specialized connectors, thereby increasing interface versatility while reducing device complexity

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

2Adaptability or versatility

If multiple connectors are provided in the chassis to support multiple interfaces, then the number of available interfaces increases, but the mounting difficulty increases

Engineering Contradiction:
Improvenumber of interfacesVSAvoidmounting difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent merges multiple connector functions into a single integrated receptacle structure. By combining USB 2.0, USB 3.0, DisplayPort, and Ethernet capabilities within one physical connector, the design reduces the total number of mounting locations required in the chassis, thereby easing manufacturing and assembly processes while maintaining comprehensive interface support

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the connector size is increased to accommodate multiple interfaces, then the number of interfaces increases, but the portable device compactness decreases

Engineering Contradiction:
Improvenumber of interfacesVSAvoidconnector area
Core Design Contradiction:
Adaptability or versatilityVSArea of moving object

Solution Approach 1:

The universal connector design allows a single compact receptacle to provide multiple interface types (USB 2.0, USB 3.0, DisplayPort, Ethernet) through dynamic signal routing via the crossbar switch. This approach maintains connector compactness suitable for portable devices while maximizing interface versatility, as the physical connector size remains small but supports multiple protocols through software-controlled switching

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