Solution Overview

Problem

Existing mobile devices are cumbersome and insecure, as they must be carried to access functions, risking theft of personal information and lack support for interacting with large screens for data input or recording interactions.

Innovation Solution

A Wearable Wireless Personal Server (WWPS) that securely stores personal information and wirelessly couples with Processing and Display Devices (PDDs), allowing secure, portable access to device functions and enabling interaction with large screens for input and data recording.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a user carries a mobile device with a bigger display screen, then the user can interact with data via a larger display, but the device becomes too big to securely and comfortably fit in a pocket

Engineering Contradiction:

Improvedisplay screen areaVSAvoiddevice volume

Core Design Contradiction:

Area of stationary objectVSVolume of moving object

Solution Approach 1:

The system divides the mobile computing function into two separate components: a wearable server device (WWPS) that stores and processes data, and a display device that provides the large screen interface. These segments communicate wirelessly, allowing the display function to be separated from the computational core, thus enabling large screen interaction without carrying a bulky device.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extracts the display function from the mobile device by allowing the WWPS to wirelessly couple with external display devices. This extraction enables users to access their personal information and interact with data on large external screens without the physical constraints of carrying a large mobile device.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If a user carries a mobile device to access functions, then the user can access personal information and online accounts, but the user risks theft of sensitive personal information stored on the device

Engineering Contradiction:

Improveaccess to personal informationVSAvoidtheft risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system separates the sensitive data storage (WWPS) from the display and input functions (external PDD). The WWPS remains securely attached to the user's body, while the external display device can be disconnected and left in secure locations. This segmentation reduces theft risk as the valuable personal information never leaves the user's possession.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces wireless communication as an intermediary between the WWPS and external display devices. This allows data access without physical connection, and the system can automatically manage connections based on proximity and authentication, reducing the risk of unauthorized access while maintaining ease of operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If a mobile device is lost, then the user loses access to functions, but a criminal may have gained access to information and accounts before the user realizes the loss

Engineering Contradiction:

Improveaccess to device functionsVSAvoidtime to detect and respond to loss

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary security actions by continuously monitoring the connection status between WWPS and external devices. When the WWPS is separated from its authorized display device or detects unauthorized access attempts, the system automatically triggers security protocols including alerting the user and potentially wiping data, preventing criminal access before the user is aware of the loss.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms where the WWPS and external devices continuously communicate their status. If the WWPS is lost or stolen, the system provides immediate feedback to the user through notifications, and can automatically respond by disabling access or wiping sensitive information, reducing the time window for criminal exploitation.

Inventive Principle:

Principle #23Feedback

4Ease of operation

If a large screen device is used for data input and interaction, then the user can interact with data via a large display screen, but the large screen device does not have write access to the mobile device

Engineering Contradiction:

Improvedata input capabilityVSAvoidwrite access capability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

Instead of having the display device write to the mobile device, the patent inverts the data flow direction: the WWPS (mobile device) wirelessly transmits data to the external display device for input, and the display device sends input commands back to the WWPS. This allows the large screen to function as both display and input interface while maintaining proper security architecture where the WWPS retains control and write access to its own data.

Inventive Principle:

Principle #13The other way round (Inversion)
