Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a polarizer is used in flexible display devices, then display functionality is achieved, but polarizer failure occurs under elevated temperature and high humidity conditions

Engineering Contradiction:

Improvepolarizer reliabilityVSAvoidtemperature and humidity impact

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

An absorption layer is introduced as an intermediary component between the display panel and the polarizing component. This absorption layer acts as a mediator that absorbs harmful gases and blocks water vapor, preventing them from reaching and damaging the polarizer, thereby improving polarizer reliability under harsh environmental conditions

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The absorption layer utilizes porous absorption material with controlled pore structures to selectively absorb harmful gases and block water vapor. The porous structure provides high surface area for absorption while maintaining flexibility and allowing light transmission, effectively protecting the polarizer without compromising display functionality

Inventive Principle:

Principle #31Porous materials

2Reliability

If polarizer failure occurs, then display effect deteriorates, but touch performance also deteriorates

Engineering Contradiction:

Improvedisplay and touch performanceVSAvoidcorrosion and structural damage

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The absorption layer serves as a protective intermediary that prevents harmful gases and water vapor from reaching the polarizer and causing corrosion. By blocking these harmful factors at the source, the absorption layer maintains both display effect and touch performance, preventing the deterioration that would otherwise occur

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The absorption layer provides beforehand protection by absorbing harmful gases and blocking water vapor before they can cause corrosion or structural damage to the polarizer. This preventive measure ensures that both display and touch functions remain reliable under elevated temperature and high humidity conditions

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
