Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If existing laser light combining devices are used, then high-brightness output can be achieved, but the device size becomes large which hinders optical path processing and internal structure layout
Solution Approach 1:
The patent segments the light combining function into multiple independent reflective stripes (first reflective stripe and second reflective stripe) that can be separately arranged and optimized. Each reflective stripe handles specific light paths from laser arrays, allowing modular design that reduces overall device volume while maintaining high-brightness output through distributed light collection and combination
Solution Approach 2:
The patent employs four-dimensional array arrangement of laser light sources and uses reflective stripes positioned in multiple spatial dimensions to redirect light paths. By utilizing dimensional space more efficiently through stereoscopic light path design, the device achieves compact structure without compromising the brightness output
2Ease of manufacture
If the device structure is simplified for easier assembly, then manufacturing efficiency improves, but achieving high-brightness output with compact structure becomes more difficult
Solution Approach 1:
The patent divides the light combining system into segmented reflective stripes that can be independently manufactured and assembled. This segmentation allows each component to be optimized separately for both manufacturing ease and optical performance, with the modular structure enabling simplified assembly while maintaining the complex light paths needed for high-brightness output
Solution Approach 2:
The reflective stripes are designed with multi-functionality, serving both as structural support elements and as optical redirecting surfaces. This universal design reduces the total number of components needed, simplifying assembly while the precise optical design of each stripe ensures high-brightness output is achieved
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case

Implementation Method 1
the first reflective stripe and the second reflective stripe are used to adjust directions along which the parallel light beams are transmitted
Implementation Method 2
