Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If conventional light-emitting display devices are used, then display functionality is achieved, but electrical connection and repair are difficult
Solution Approach 1:
The light-emitting element is divided into separable components including a first electrode, semiconductor layer, second electrode, and insulating layer. This segmentation allows individual components to be replaced or repaired independently, improving ease of repair while maintaining manageable device complexity through modular architecture.
Solution Approach 2:
An insulating layer is introduced as an intermediary component between the electrodes and semiconductor structures. This intermediary layer facilitates easier electrical connection and repair by providing a controlled interface that simplifies the connection process and allows for easier replacement without direct exposure of conductive elements.
2Manufacturing precision
If high-resolution display is implemented, then display quality improves, but connection and repair difficulty increases
Solution Approach 1:
By segmenting the light-emitting element into replaceable modules with standardized interfaces, the patent enables high-resolution display implementation while maintaining repairability. Each module can be precisely manufactured to high standards yet replaced as a unit, decoupling manufacturing precision requirements from repair difficulty.
Solution Approach 2:
The insulating layer and electrode structures are pre-configured with connection interfaces that facilitate easier assembly and repair. This preliminary arrangement of conductive and insulating layers creates standardized connection points that simplify both high-precision manufacturing and subsequent repair operations.
