Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If anti-view pixels are driven in traditional modes, then the display panel can switch between anti-view and sharing modes, but the interference effect with information reading is limited and not reliable enough

Engineering Contradiction:
Improveinformation protection reliabilityVSAvoidanti-view effectiveness
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies dynamics by transitioning from static anti-view pixel states to dynamic sequential and disordered driving modes. The anti-view pixels are activated in specific sequences and patterns that change over time, creating dynamic light mixing effects that continuously disrupt information readability from wide viewing angles while maintaining reliability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements periodic action through sequential driving where anti-view pixels are activated in repeating patterns and cycles. This periodic activation creates rhythmic light mixing effects that systematically interfere with information reading attempts, enhancing the reliability of information protection through consistent, predictable interference patterns.

Inventive Principle:
Principle #19Periodic action

2Reliability

If anti-view pixels are activated continuously, then information protection is enhanced, but the sharing mode usability is affected

Engineering Contradiction:
Improveinformation protectionVSAvoidsharing mode usability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent uses dynamics to enable flexible switching between anti-view and sharing modes through controlled activation patterns. The anti-view pixels can be dynamically activated or deactivated based on the desired mode, allowing seamless transitions that maintain ease of operation while ensuring information protection when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies parameter changes by modifying the activation state of anti-view pixels between modes. In sharing mode, the activation parameters are adjusted to minimize or eliminate anti-view effects, while in anti-view mode, the parameters are changed to maximize information protection, thus maintaining ease of operation across different usage scenarios.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If sequential driving and disordered driving are applied to anti-view pixels, then anti-view effectiveness is improved by attracting attention and disrupting adaptability, but the device complexity increases

Engineering Contradiction:
Improveanti-view effectivenessVSAvoidcontrol complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a control device that can perform multiple driving functions (sequential driving, disordered driving, and mode switching) through a unified control architecture. This multi-functional approach manages the complexity by consolidating control operations into a single device that handles various anti-view pixel activation patterns without requiring separate dedicated circuits for each function.

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

Solution Approach 2:

The patent uses parameter changes to manage complexity by controlling the activation patterns of anti-view pixels through adjustable parameters such as timing, sequence, and intensity. By modifying these parameters, the system can achieve different driving modes (sequential, disordered) and switch between anti-view and sharing modes, thereby managing complexity through flexible parameter control rather than complex hardware architecture.

Inventive Principle:
Principle #35Parameter changes
