Solution Overview

Problem

Conventional solutions for providing external input/output devices to portable electronic devices often require dedicated auxiliary devices or docking stations, lacking convenience and versatility in enabling seamless mode switching between input and output functions.

Innovation Solution

A method and device configuration that allows portable electronic devices to switch between input and output modes when connected to a docking station, utilizing a detect module to monitor connection events and a mode switch module to adjust device functionality, enabling the device to operate as both an input and output device based on user interaction and proximity sensing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a dedicated auxiliary input/output device or docking station is used, then external input/output functionality is provided, but device complexity and requirement for separate components increases

Engineering Contradiction:
Improveexternal input/output functionalityVSAvoidrequirement for separate components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The portable electronic device's display is made multi-functional by enabling it to serve both as an output display and as an input device (functioning as a mouse or pointing device). This allows the same component to perform multiple functions that traditionally required separate devices, thereby reducing the need for additional components while maintaining external input/output functionality.

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

Solution Approach 2:

The invention merges the functions of a display and an auxiliary input device (mouse/pointing device) into a single integrated component. By combining these previously separate functions into one device, the system reduces complexity and eliminates the need for separate auxiliary input/output devices or docking stations.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If conventional docking station solutions are used, then external input/output capabilities are enabled, but ease of operation and convenience decreases due to complex setups

Engineering Contradiction:
Improveexternal input/output capabilitiesVSAvoidconvenience of setup and use
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The portable electronic device automatically detects when it is connected to a power source and autonomously switches its display between output mode and input mode without requiring user configuration or complex setup procedures. This self-service capability eliminates the need for manual docking station configurations and simplifies operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The display dynamically changes its function based on operational conditions - switching between display-only mode and input device mode. This dynamic adaptability allows the device to automatically adjust its functionality according to whether it is connected to a power source, providing convenience without requiring complex setup procedures.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the display functions as both input and output device, then versatility is improved, but device functionality and operational modes become more complex

Engineering Contradiction:
Improvedual input/output functionalityVSAvoidoperational modes and switching logic
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system uses feedback from power connection detection to automatically control the display's operational mode. When the device detects a power connection, it automatically switches the display to input mode; when disconnected, it returns to output mode. This feedback-based automatic switching simplifies the operational complexity by eliminating manual mode selection.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The display's operational parameters (input vs. output mode) are changed based on the power connection status parameter. By using the power connection state as the controlling parameter, the system simplifies the switching logic between different operational modes, making the dual functionality manageable through a single clear condition.

Inventive Principle:
Principle #35Parameter changes
