Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional light emitting device structures are used, then emission faces can be arranged, but spacing between emission faces is large
Solution Approach 1:
The device is segmented into multiple element structure bodies, each containing a light emitting element with lateral faces. By dividing the overall structure into discrete modular units with cover members, the design enables tighter spacing while maintaining structural integrity and optical performance.
Solution Approach 2:
The invention transitions from conventional planar arrangements to a three-dimensional configuration where light emitting elements are positioned vertically on submount substrates with cover members enclosing lateral faces. This vertical stacking approach reduces horizontal spacing between emission faces.
2Area of stationary object
If emission faces are densely arranged, then device size is reduced, but manufacturing precision requirements increase
Solution Approach 1:
Cover members are formed in advance to precisely enclose the lateral faces of light emitting elements. This preliminary formation of protective structures establishes precise positioning boundaries before final assembly, reducing the need for high-precision positioning during manufacturing.
Solution Approach 2:
Cover members function as protective shells that encapsulate light emitting elements. These flexible enclosing structures provide mechanical support and precise positioning while allowing for manufacturing tolerances, reducing the overall device area without compromising positioning precision.
