Solution Overview

Problem

Current end-user devices, such as mobile phones and tablets, have limited port spaces and tight port arrangements, leading to inefficient port usage due to the physical size of devices and connectors, making it difficult to access multiple ports simultaneously.

Innovation Solution

A port extension apparatus with a main port module and additional data and video port modules that enable multiple devices to connect and transmit data, increasing port utilization efficiency by forming transmission paths and controlling data transmission between connected devices and end-user devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If ports are provided in end-user devices, then data transmission capability is improved, but port accessibility deteriorates due to tight space and limited device size

Engineering Contradiction:
Improveport transmission capabilityVSAvoidport accessibility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

A USB hub is introduced as an intermediary device between the end-user device and multiple to-be-connected devices. The hub receives data from the end-user device through a first USB port and distributes it to multiple second USB ports, enabling simultaneous access to multiple ports without requiring additional ports on the original device.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If multiple ports are provided in end-user devices, then port utilization efficiency is improved, but device volume increases

Engineering Contradiction:
Improveport utilization efficiencyVSAvoiddevice volume
Core Design Contradiction:
ProductivityVSVolume of moving object

Solution Approach 1:

The port expansion function is segmented into a separate USB hub device rather than integrating multiple ports directly into the end-user device. This allows the end-user device to maintain its compact size while the hub provides multiple ports for simultaneous device connections, achieving high port utilization without increasing the original device's volume.

Inventive Principle:
Principle #1Segmentation

3Reliability

If a port is occupied by a large connector, then connection stability is improved, but other ports become inaccessible

Engineering Contradiction:
Improveconnection stabilityVSAvoidport accessibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The USB hub acts as a mediator that receives the large connector connection on one port and provides multiple smaller connector ports on the other side. This allows stable connection through the hub while maintaining accessibility to multiple ports simultaneously, as the hub distributes the connection to multiple second USB ports.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Port extension apparatus for providing better usage and utilization efficiency ports of end-user devices are disclosed. Port extension apparatus includes at least a main port module for connection to end-user device, first data port module, data transmission control module, second data port module, and video port module. When a to-be-connected device connects to the first data port module, the first data port module and the main port module form a transmission path enabling data transmission between the to-be-connected device and the end-user device. When the to-be-connected device connects to the second data port module, the data transmission control module controls the data transmission between the to-be-connected device and the end-user device. When the to-be-connected device connects to the video port module, the data transmission control module receives the to-be-displayed information from the end-user device and transmits to the to-be-connected device to display.
