Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single chip is used to manage dual-screen display, then device complexity is reduced, but the capability to efficiently manage simultaneous and different content displays is insufficient

Engineering Contradiction:

Improvechip structureVSAvoiddual-screen display capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The VB1 interface is segmented into a first VB1 output terminal and a second VB1 output terminal, allowing independent control of each display screen. This segmentation enables the single chip to simultaneously output different content to different screens while maintaining overall system simplicity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The single chip is designed with multi-functional capability to handle both simultaneous display and different display modes through the divided VB1 interface. The data processing module can process input data to generate either identical or different content for the two output terminals, making the chip universally applicable for various dual-screen display scenarios.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple chips are used to achieve simultaneous and different content display, then display capability is improved, but device complexity and cost increase

Engineering Contradiction:

Improvedual-screen display capabilityVSAvoidchip structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the functions of multiple chips into a single chip by integrating the VB1 interface division and data processing capabilities. The first and second VB1 output terminals are combined within one chip, eliminating the need for separate chips while maintaining the ability to display different content on dual screens.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single chip is designed with multi-functional capability to handle both simultaneous display and different display modes through the divided VB1 interface. The data processing module can process input data to generate either identical or different content for the two output terminals, making the chip universally applicable for various dual-screen display scenarios.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If a divided VB1 interface is implemented, then simultaneous and different display function is achieved, but interface complexity increases

Engineering Contradiction:

Improvedisplay functionVSAvoidinterface structure

Core Design Contradiction:
