Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate driving chip is provided for each screen (primary and auxiliary), then each screen can be independently driven, but the power consumption increases and device complexity increases

Engineering Contradiction:

Improveindependent screen driving capabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent merges the driving functions for both primary and auxiliary screens into a single driving chip. The driving chip includes first and second driving circuits that can independently drive respective screens while sharing common resource circuits (emission control circuit, dimming control circuit, sensing circuit), thereby reducing power consumption and device complexity while maintaining independent screen driving capability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The driving chip is designed with multi-functionality to control both primary and auxiliary screens. It includes universal control circuits (emission control circuit, dimming control circuit, sensing circuit) that can serve both screens, while maintaining separate driving circuits for independent screen control, thus achieving energy efficiency without sacrificing functional independence

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a separate driving chip is provided for each screen (primary and auxiliary), then each screen can be independently driven, but the device complexity increases

Engineering Contradiction:

3Ease of manufacture

If traditional display structures are used without connecting regions, then manufacturing is simpler, but the display flexibility and information exhibition capability are limited

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidinformation exhibition flexibility

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent segments the display panel into distinct functional regions: a first display region, a connecting region, and a second display region. The connecting region contains signal transmission lines that electrically connect the two display regions, enabling flexible information exhibition across different screen configurations while maintaining manufacturing feasibility through standardized regional division

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a connecting region as an intermediate dimensional space between two display regions. This connecting region contains signal transmission lines that enable electrical connection while allowing flexible spatial arrangement of screens (e.g., folded, rolled, or adjacent configurations), thus enhancing display versatility without complicating manufacturing

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
