Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing of optical systems with beam deflection and diaphragm elements is time-consuming and complex, especially in multi-beam systems, due to the need for precise alignment of these elements, which is difficult to achieve through manual adjustment.
Innovation Solution
An optical system is manufactured by fixing a beam deflection unit and a screening element together using a holder, where the screening element is processed with light beams to form a diaphragm element, ensuring the diaphragm aperture is aligned with the beam deflection element, eliminating the need for separate alignment of the diaphragm and beam deflection elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment is used for positioning beam deflection elements and diaphragm elements, then alignment precision can be achieved, but the manufacturing process becomes time-consuming and complex
Solution Approach 1:
The patent applies preliminary action by pre-positioning the diaphragm element in a predefined arrangement relative to the beam deflection element before final assembly. The holder is designed with predetermined geometric relationships that automatically establish the correct alignment when components are assembled, eliminating the need for time-consuming manual adjustment during final assembly while maintaining high alignment precision.
2Manufacturing precision
If manual adjustment is used for positioning beam deflection elements and diaphragm elements, then alignment precision can be achieved, but the device design becomes complex and voluminous
Solution Approach 1:
The patent merges the positioning function into the holder structure itself. The holder is designed with integrated geometric features that simultaneously provide mechanical support and precise alignment, combining multiple functions (support, positioning, alignment) into a single component. This eliminates the need for separate adjustment mechanisms and reduces overall system complexity.
3Manufacturing precision
If individual positioning is performed for each element in multi-beam systems, then alignment precision can be achieved, but the manufacturing effort becomes unjustifiably high
Solution Approach 1:
The patent applies universality by designing the holder to simultaneously position and align multiple beam deflection elements and diaphragm elements according to a predefined arrangement. The holder structure incorporates geometric relationships that automatically ensure correct alignment for all elements in the multi-beam system during a single assembly operation, eliminating the need for individual positioning of each element.
