Innovation Solution

Implementing a virtual operating system on a mobile device to manage connections and provide screen frames and inputs to a low-power device, enabling execution of applications and communication with mobile device components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If a device with low computing power is used, then space and weight constraints are satisfied, but functionality and computing capability deteriorate

Engineering Contradiction:
Improvedevice weightVSAvoidfunctionality
Core Design Contradiction:
Weight of moving objectVSAdaptability or versatility

Solution Approach 1:

The system divides functionality into two segments: the thin device handles display and basic input, while the mobile device handles computing-intensive tasks and application execution. This segmentation allows the thin device to remain lightweight while accessing advanced functionality through the connected mobile device.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mobile device serves multiple functions: it acts as a computing platform, runs applications, processes sensor data, and provides display output to the thin device. This multi-functionality compensates for the thin device's limited capabilities while maintaining its portability advantages.

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

2Adaptability or versatility

If apps are installed on the small device, then functionality is enhanced, but device complexity and space requirements increase

Engineering Contradiction:
ImprovefunctionalityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts application execution from the thin device and relocates it to the mobile device. The thin device retains only essential system functions, while applications are installed and run on the mobile device, reducing complexity and space requirements on the thin device.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A communication interface acts as an intermediary between the thin device and mobile device, enabling the thin device to access application functionality remotely without hosting the applications locally. This mediator facilitates functionality enhancement while maintaining device simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Area of stationary object

If screen mirroring is used, then display capability is provided, but adaptability to different screen sizes and operating independence deteriorate

Engineering Contradiction:
Improvedisplay areaVSAvoidscreen size adaptability
Core Design Contradiction:
Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts display parameters including screen resolution, refresh rate, and content scaling based on the thin device's specific display characteristics. This allows optimal adaptation to different screen sizes and types rather than simple mirroring.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

Instead of mirroring the mobile device's display to the thin device, the system inverts the approach by having the thin device's display capabilities drive the content rendering, with the mobile device adapting its output to match the thin device's display parameters.

Inventive Principle:
Principle #13The other way round (Inversion)

4Area of stationary object

If screen mirroring is used, then display functionality is provided, but ease of operation for independent mobile device use worsens

Engineering Contradiction:
Improvedisplay areaVSAvoidoperating independence
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The connection between thin device and mobile device is made dynamic rather than static. The system can switch between connected mode (using thin device display) and independent mode (using mobile device display), allowing users to operate the mobile device independently when needed while utilizing the thin device display when convenient.

Inventive Principle:
Principle #15Dynamics
