Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional methods are used to align micro LEDs, then the alignment process can be performed with simple equipment, but the alignment precision and speed are insufficient due to the small size of micro LEDs
Solution Approach 1:
The alignment device is divided into multiple independent movable parts: a body part receiving movement by a first moving part, a mask plate receiving movement by a second moving part, and a head part receiving movement by a third moving part. This segmentation allows each component to be controlled independently, achieving high alignment precision without requiring overly complex integrated systems.
Solution Approach 2:
A mask plate is introduced as an intermediary component disposed between the body and the head part. The mask plate receives movement by a second moving part to move between the body and the head part, serving as a mediator that enables precise positioning and constant interval spacing of micro LEDs during the alignment process.
2Productivity
If multiple separate processes are used to align micro LEDs of various sizes, then each size can be precisely aligned, but the overall process time and complexity increase
Solution Approach 1:
The alignment device is designed with universal functionality to align all electronic components in various sizes, particularly micro light emitting diodes in various sizes, through a single process. The mask plate with its movable design can accommodate different component sizes and configurations, eliminating the need for multiple separate alignment processes.
Solution Approach 2:
The mask plate is designed to be dynamically movable between the body and the head part, receiving movement by a second moving part. This dynamic capability allows the mask plate to adapt its position for different component sizes and types, enabling precise alignment of various micro LED sizes within a single unified process.
