Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional connection methods are used for light emitting elements to display substrate, then device complexity is reduced, but connection reliability deteriorates

Engineering Contradiction:
Improveconnection reliabilityVSAvoidmodule structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into the molding structure: it serves as both the protective encapsulation for light emitting elements and the connection interface to the display substrate. The molding integrates electrode extensions and connection portions that directly bond to the substrate, eliminating the need for separate connection components and achieving both reliability and simplicity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The molding structure performs multiple functions simultaneously: it protects light emitting elements, provides electrical connections through integrated electrodes, enables mechanical bonding to the substrate, and facilitates heat dissipation. This multi-functionality resolves the contradiction by achieving reliable connections without adding device complexity.

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

2Manufacturing precision

If light emitting elements are firmly connected to display substrate, then display quality improves, but manufacturing complexity increases

Engineering Contradiction:
Improvedisplay qualityVSAvoidmanufacturing process simplicity
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The molding structure is pre-formed with integrated electrodes and connection portions before assembly. This preliminary preparation ensures precise alignment and firm connection when the module is assembled to the display substrate, achieving high display quality while simplifying the final manufacturing process.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If electrodes extend in multiple directions for better connection, then connection reliability improves, but device complexity increases

Engineering Contradiction:
Improveelectrical connection reliabilityVSAvoidelectrode structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple electrode extensions into a single integrated molding structure. The electrodes extend in multiple directions within the molding to achieve reliable electrical connections, but this complexity is contained within the molding itself rather than requiring separate electrode components, thus maintaining overall device simplicity.

Inventive Principle:
Principle #5Merging (Combining)
