Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If touch panel and display screen are assembled as separate components, then touch functionality is achieved, but device thickness increases

Engineering Contradiction:

Improvetouch functionalityVSAvoiddevice thickness

Core Design Contradiction:

ReliabilityVSLength of stationary object

Solution Approach 1:

The patent combines the touch panel and display screen into a single integrated structure where the conductive layer is embedded within the display screen's adhesive layer. This merging eliminates the need for separate assembly of touch panel and display screen, thereby reducing device thickness while maintaining touch functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The display screen is designed to perform multiple functions: it serves as both the display component and the touch sensing component. The conductive layer embedded in the adhesive layer enables touch sensing functionality within the display screen itself, making it a multi-functional component that eliminates the need for a separate touch panel.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If touch panel and display screen are assembled as separate components, then touch functionality is achieved, but assembly complexity increases

Engineering Contradiction:

Improvetouch functionalityVSAvoidassembly process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

By merging the touch panel and display screen into a single integrated component, the patent reduces the number of assembly steps. The conductive layer is embedded within the adhesive layer during display screen manufacturing, eliminating the need for separate touch panel assembly operations.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If touch panel and display screen are assembled as separate components, then touch functionality is achieved, but manufacturing cost increases

Engineering Contradiction:

Improvetouch functionalityVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The integration of touch panel and display screen into a single component reduces manufacturing costs by eliminating separate production and assembly processes. The conductive layer is embedded within the adhesive layer during display screen manufacturing, streamlining production and reducing overall manufacturing complexity and cost.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A polarizer module includes a polarizer substrate, an adhesive layer coated on the polarizer substrate, and a conductive layer embedded in the adhesive layer. The conductive layer includes a first conductive pattern and a second conductive pattern spaced apart from each other in the extending direction of the adhesive layer to form a sensing structure. The polarizer module can implement touch operation and output polarization light. A touch screen using the polarizer module is also provided.
