Solution Overview

Problem

Portable computing devices (PCDs) face limitations due to their small form factor, which restricts the number of ports and connections, hindering access to their increasing computing power and capabilities.

Innovation Solution

A method and system for managing PCD displays when docked with a docking station, involving connecting a data driver to the docking station display, transmitting primary and secondary display signals, and displaying various types of information, including application content, controls, and user interfaces, to enhance usability and functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the PCD form factor is reduced to improve portability, then ease of carrying is improved, but the number of ports and connections is reduced

Engineering Contradiction:
ImproveportabilityVSAvoidnumber of ports and connections
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The docking station serves multiple functions including display output, audio output, charging, and data transfer through a single universal interface. The system allows the PCD to access desktop-class capabilities (large display, keyboard, mouse, high-speed internet) through the docking station, effectively providing multi-functionality without adding physical ports to the PCD itself.

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

2Ease of operation

If the PCD form factor is reduced to improve portability, then ease of carrying is improved, but access to computing power and capabilities is limited

Engineering Contradiction:
ImproveportabilityVSAvoidaccess to computing capabilities
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The docking station acts as an intermediary between the portable PCD and desktop computing resources. It mediates the connection between the small PCD and large displays, keyboards, mice, and other peripherals, allowing the user to access full computing capabilities while maintaining the portability of the PCD itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If display information is shown only on the PCD display, then device simplicity is maintained, but usability for detailed content is reduced

Engineering Contradiction:
Improvedisplay system simplicityVSAvoidcontent viewing usability
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The display system is segmented into multiple output channels: the PCD's own display for portable use, and the docking station's display for detailed content viewing. The system can segment display content between these devices, showing different information on each display simultaneously, or mirroring the same content on both displays depending on user needs.

Inventive Principle:
Principle #1Segmentation
