Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional polarizing films are used on panels, then polarization function is achieved, but manufacturing complexity and cost increase

Engineering Contradiction:

Improvepolarization efficiencyVSAvoidmanufacturing process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the polarizing function directly into the panel structure by forming polarizing layers through coating processes during panel manufacturing. This integration eliminates the need for separate polarizing films and their associated lamination processes, thereby reducing manufacturing complexity while maintaining polarization efficiency.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces the mechanical lamination process of traditional polarizing films with a coating-based formation process. By using coating techniques to create polarizing layers directly on the panel, the manufacturing process becomes more integrated and less complex, avoiding the need for separate film application and bonding steps.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If multiple separate polarizing films are laminated on panels, then polarization performance is improved, but manufacturing cost and process time increase

Engineering Contradiction:

Improvepolarization performanceVSAvoidmanufacturing efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent combines multiple polarizing functions into a single integrated coating process. Instead of laminating multiple separate polarizing films in sequential steps, the coating method allows for the formation of multiple polarizing layers in a more streamlined process, improving manufacturing efficiency while achieving the same or better polarization performance.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent performs the polarizing layer formation as a preliminary action during the panel manufacturing process itself, rather than as a subsequent separate step. By coating and forming polarizing layers while the panel is being manufactured, the process eliminates later lamination steps, thereby improving overall productivity and reducing manufacturing time.

Inventive Principle:

Principle #10Preliminary action

3Illumination intensity

Solution Approach 1:

The patent merges the polarizing layer formation with the existing panel manufacturing process using coating techniques. This integration eliminates the need for purchasing, handling, and laminating separate polarizing films, thereby reducing material costs and processing costs while maintaining enhanced optical properties.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces the expensive and complex film lamination system with a more cost-effective coating-based system. By using coating processes that can be integrated into existing manufacturing lines, the patent reduces equipment investment and operational costs while achieving the same optical enhancement through polarizing layers.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
