Solution Overview

Problem

Smartphones with small screens face challenges in displaying multimedia content effectively due to limited screen size and the absence of physical buttons, leading to difficulties in reading and typing, and existing solutions are either limited to static content or bulky and inconvenient for portability.

Innovation Solution

A controlling device with a Screen Resident Device Driver and a Mobile Phone Resident Device Driver that enables wireless communication via Bluetooth and Wi-Fi, allowing for real-time image enlargement and synchronization between a smartphone and a monitor, using TCP/IP and USB-Host protocols to manage network communication and display resolution, facilitating seamless multimedia playback and input device control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If the screen size of the smartphone is increased to improve multimedia display quality, then the reading and viewing experience is improved, but the portability and handiness of the device deteriorates

Engineering Contradiction:
Improvescreen sizeVSAvoidportability
Core Design Contradiction:
Area of moving objectVSEase of operation

Solution Approach 1:

The patent combines the smartphone display with an external monitor to create an extended display system. The smartphone serves as a portable computing device that can wirelessly connect to and extend its display onto a larger external monitor, allowing users to enjoy both small portable form factor and large screen real estate simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention enables the smartphone to serve multiple functions: it acts as both a standalone portable device and as a remote control or extension for external displays. The system allows the smartphone to function as a media player, remote controller, and display manager, eliminating the need for separate dedicated devices.

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

2Ease of operation

If physical buttons are added to the smartphone to improve typing speed and user comfort, then the ease of operation is improved, but the device complexity and bulkiness increase

Engineering Contradiction:
Improvetyping speedVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces an external monitor with physical buttons as an intermediary device. The monitor's physical buttons serve as a remote control interface for the smartphone, allowing users to input commands and control media playback without adding physical buttons to the smartphone itself. This separates the input function from the computing device.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention replaces mechanical physical buttons on the smartphone with wireless communication protocols (Bluetooth, Wi-Fi) that enable the external monitor's physical interface to control the smartphone remotely. This substitution maintains the benefits of physical input while avoiding the need to integrate mechanical components into the smartphone.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If wireless transmission technology is used to enable multimedia playback on the smartphone, then the portability is improved, but the reliability of video playback may deteriorate

Engineering Contradiction:
ImproveportabilityVSAvoidvideo playback stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system provides multiple wireless communication protocols (Bluetooth and Wi-Fi) that can be used interchangeably or simultaneously. This multi-protocol approach ensures reliable video transmission by allowing the system to switch between protocols based on availability and performance, maintaining both portability and reliability.

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

AI summary

A controlling device for shifting images in a display of a smartphone is provided with a monitor installed with a Screen Resident Device Driver. The Screen Resident Device Driver includes a Real Time Operating System that is in charge of a TCP/IP communication protocol, a USB-Host communication protocol, a Network and Display Server, a mobile phone and communication process driver, and a Bluetooth-Host communication protocol. The device further provides a mobile phone comprising a Mobile Phone Resident Device Driver installed in a mobile phone body. The Mobile Phone Resident Device Driver includes a Resident Detect Operation Service, a Remote Human Interface Device (HID), a Remote HID-Disk, a Display Resolution Control, a Remote Transaction Event Handler, and a Virtual Display Driver. Thereby, the image on the mobile phone is enlarged according to the geometric ratio so as to contribute to the virtual image.
