Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conductive element is designed to function as both light emitter and electrical connector, then the functionality and efficiency of display devices are enhanced, but the device complexity increases due to the need for multiple layers and structures
Solution Approach 1:
The conductive element is designed to perform multiple functions simultaneously: the active layer emits light when electrical signals are applied, while the conductive pattern layer provides electrical connectivity between components. This multi-functional design allows a single element to serve as both light emitter and electrical connector, enhancing versatility without requiring separate components
Solution Approach 2:
The conductive element is divided into distinct functional layers: semiconductor layers for electrical conduction, active layer for light emission, element insulating layer for electrical isolation, and conductive pattern layer for connectivity. This segmentation allows each layer to be optimized for its specific function while working together as an integrated multi-functional element
2Reliability
If the conductive pattern layer is electrically insulated from the semiconductor layers, then electrical isolation is achieved, but the manufacturing precision requirements increase due to the need for precise layer alignment and insulation
Solution Approach 1:
The element insulating layer acts as an intermediary between the semiconductor layers and the conductive pattern layer. This intermediate insulating layer provides electrical isolation and prevents short circuits, while its structured design with exposed end portions allows for controlled electrical connections where needed
Solution Approach 2:
The insulating properties are applied locally where needed: the element insulating layer covers the active layer to provide electrical isolation, but exposes the end portions of semiconductor layers to allow electrical connections at specific locations. This local differentiation of insulating/conductive properties achieves reliable electrical isolation without requiring complete insulation
