Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple blue laser diodes are combined into a multi-chip laser light source to increase density, then the laser light source density is improved, but the occupied area becomes excessively large
Solution Approach 1:
The patent transitions from a planar arrangement of light source groups to a three-dimensional configuration where light source groups are positioned on different planes. The first and third light source groups are arranged on one plane while the second light source group is positioned on a different plane, enabling vertical stacking and reducing the horizontal occupied area while maintaining high light source density.
Solution Approach 2:
The patent implements a nested arrangement where beam-combining devices are positioned between light source groups, with some beam-combining devices partially overlapping or interlocking with others. The first beam-combining device is disposed between the first and second light source groups, while the second beam-combining device is disposed between the second and third light source groups, creating a compact nested structure that maximizes space utilization.
2Stability of the object's composition
If fixed structures and routing areas are provided on the back and surroundings of the multi-chip laser light source, then structural stability is improved, but heat dissipation becomes difficult
Solution Approach 1:
The patent divides the light source system into distinct modular groups (first, second, and third light source groups) positioned on different planes, with beam-combining devices separating them. This segmentation allows independent heat dissipation pathways for each light source group, preventing heat accumulation and improving overall thermal management while maintaining structural stability through modular construction.
Solution Approach 2:
By positioning light source groups on different planes rather than a single plane, the patent creates vertical separation that facilitates heat dissipation in the vertical dimension. This three-dimensional arrangement allows heat to dissipate more effectively through multiple directions and reduces thermal interference between adjacent light source groups, solving the heat dissipation problem while maintaining structural integrity.
3Ease of manufacture
If conventional light source arrangement is used, then assembly is simplified, but light beam alignment becomes discontinuous or uneven
Solution Approach 1:
The patent introduces beam-combining devices as intermediary optical elements between the light source groups. These beam-combining devices serve as mediators that precisely align and combine the light beams from different light source groups, ensuring continuous and uniform light beam alignment. The beam-combining devices simplify the alignment process by providing a standardized interface between light source groups while achieving high precision beam combination.
