Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional light emitting element design with limited electrode configurations is used, then the structure is simple, but the assembly rate decreases and contact failures increase when the element is flipped or laid sideways during transfer
Solution Approach 1:
The patent employs asymmetric electrode positioning where the first electrode is located at a corner of the semiconductor layer and the second electrode is positioned at the center, creating an asymmetric configuration that enables reliable identification and connection regardless of the element's orientation during assembly
Solution Approach 2:
The electrode configuration provides universal connectivity by ensuring that the asymmetric arrangement of electrodes allows the light emitting element to be connected to the display panel in multiple orientations (upright, flipped, sideways), making the connection process orientation-independent
2Adaptability or versatility
If the light emitting element is designed with orientation-specific electrode placement, then the manufacturing process is simple, but the element cannot be connected to the panel regardless of placement direction
Solution Approach 1:
By positioning the first electrode at a corner and the second electrode at the center, the design creates an asymmetric pattern that is easily manufacturable while providing multiple valid connection orientations, achieving adaptability without excessive complexity
Solution Approach 2:
The patent adds orientational versatility by designing the electrode layout to function correctly across different spatial dimensions and rotations, transforming a single-orientation connection system into a multi-orientation system
