Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple apertures are arranged on a single substrate with the laser scanner, then the device structure is integrated, but the adjustment of aperture positions becomes complex and difficult
Solution Approach 1:
The aperture unit is separated from the laser scanner and positioned on a movable support mechanism. This segmentation allows the aperture unit to be independently adjusted in position and angle without being constrained by the laser scanner's fixed substrate structure, thereby simplifying the adjustment process while maintaining integration through the support mechanism connection.
2Manufacturing precision
If the aperture unit is fixed on a substrate, then the structure is stable, but the precision of electrostatic latent image formation is reduced due to inability to adjust aperture positions
Solution Approach 1:
The aperture unit is mounted on a movable support mechanism that enables dynamic adjustment of the aperture positions and angles. This dynamic configuration allows precise optimization of the aperture arrangement for high-precision electrostatic latent image formation, while the support mechanism provides structural stability when positioned, effectively combining flexibility with stability.
