Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate manufacturing and coupling of input lens array, output lens array, and shield are used, then beam pattern formation is achieved, but manufacturing process complexity increases
Solution Approach 1:
The patent merges the input lens array and output lens array into a single integrated micro lens array structure. The input lenses and output lenses are formed as one unified component with corresponding optical axes that cross at specific points, eliminating the need for separate manufacturing and coupling processes while maintaining the beam pattern formation capability.
Solution Approach 2:
The patent removes the shield component from the conventional three-component structure (input lens array, output lens array, and shield). By extracting this element and redesigning the lens array configuration, the system achieves beam pattern formation through the disposed relationship of input and output lenses alone, thereby simplifying the manufacturing process.
2Manufacturing precision
If separate manufacturing and coupling of components is used, then beam pattern formation is achieved, but manufacturing time and cost increase
Solution Approach 1:
The input lens array and output lens array are combined into a single integrated micro lens array that can be manufactured in one process. This merging eliminates the multiple manufacturing steps and coupling operations required in conventional approaches, significantly improving manufacturing efficiency and reducing production time and cost.

AI summary
An optical module includes a light source that outputs light, and a micro lens array (MLA) module provided on a front side of the light source, and to which the light is input. The MLA module includes an input lens array, to which the light is input, and includes a plurality of input lenses. An output lens array provided on a front side of the input lens array, that outputs the light input from the input lens array includes a plurality of output lenses, where optical axes of the plurality of output lenses extend in a forward/rearward direction and cross centers of the plurality of input lenses.
