Innovation Solution
An apparatus and method for manufacturing display apparatuses that include a chamber with a stage unit and optical unit, where the stage unit fixes a target, and the optical unit processes the target using a laser, allowing for rotational and vertical movement, pressure adjustment, and precise laser alignment, enabling efficient processing of targets regardless of their orientation and size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the chamber size is reduced to shrink the apparatus size, then the apparatus becomes more compact, but it becomes difficult to handle targets with varying orientations and maintain processing precision
Solution Approach 1:
The stage unit is designed to be rotatable around a first axis and movable in a vertical direction, allowing dynamic adjustment of target orientation and position. This enables the system to adapt to targets with varying orientations while maintaining processing precision within a compact chamber environment.
Solution Approach 2:
The laser radiating unit is positioned outside the chamber and radiates laser through a window, utilizing the spatial dimension outside the chamber for laser source placement. This allows the chamber to remain compact while still providing effective laser processing capability through the window interface.
2Adaptability or versatility
If the stage unit is made multi-functional with rotation and vertical movement, then the apparatus can handle various target orientations, but the device complexity increases
Solution Approach 1:
The stage unit integrates multiple functions including rotation around the first axis and vertical movement along the first axis direction. This multi-functional design allows a single stage unit to handle targets with various orientations and positions, reducing the need for multiple separate mechanisms.
Solution Approach 2:
The pressure adjusting unit mediates between the chamber environment and the stage unit by controlling chamber pressure. This allows the stage unit to operate in controlled pressure conditions, enabling versatile target handling while protecting sensitive mechanical components from environmental damage.
3Volume of moving object
If the laser radiating unit is positioned outside the chamber, then the apparatus size is reduced, but it becomes difficult to align and move the laser precisely
Solution Approach 1:
The laser moving unit includes a controller that receives information about the stage unit's position and rotation state, and adjusts the laser radiating unit's position accordingly. This feedback mechanism enables precise laser alignment with the target despite the laser unit being positioned outside the chamber.
Solution Approach 2:
The laser moving unit utilizes an air-bearing mechanism to enable smooth, precise movement of the laser radiating unit along the processing path. This replaces traditional mechanical guidance systems with air-bearing technology, achieving high precision laser positioning while maintaining a compact overall apparatus size.
