Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different types of illumination systems use different light path designs, then the specific optical requirements can be met, but the types, quantities, and positions of optical elements need to be re-distributed, resulting in re-design of configuration modes
Solution Approach 1:
The patent applies universality by designing a standardized mounting structure for optical elements that can accommodate different types of light sources (UHP lamps, LEDs, laser diodes) without requiring re-design. The mounting structure includes a mounting plate with a through hole and fixing components that can secure various optical elements (lens arrays, light-condensing lenses, integrating rods) in fixed positions, enabling the same optical system configuration to work with multiple illumination system types.
2Reliability
If optical elements are re-distributed for different light sources, then the optimal light path can be achieved, but the device complexity increases due to multiple configuration modes
Solution Approach 1:
The patent applies segmentation by dividing the optical system into modular components: a fixed mounting structure and replaceable optical elements. The mounting plate with through holes and fixing components forms a standardized base structure, while optical elements (lens arrays, light-condensing lenses, integrating rods) can be independently selected and mounted. This modular approach allows optimal light path configuration without increasing overall system complexity.
3Reliability
If conventional illumination systems are designed for specific light sources, then the optical performance is optimized, but the ease of manufacture decreases due to custom design requirements
Solution Approach 1:
The mounting structure serves multiple functions: it provides a standardized platform for mounting various optical elements, enables easy replacement and adjustment of components, and maintains optimal optical performance across different light source types. The through hole in the mounting plate allows passage of light beams while the fixing components secure elements in precise positions, achieving both manufacturing ease and optical optimization.

Implementation Method 1
The first light-condensing lens has a first-half portion and a second-half portion, where the first-half portion is located on a transmitting path of the first beam
Implementation Method 2

Implementation Method 3
The mirror is disposed on a transmitting path of the second beam at least partially from the first beam splitter, where the first part beam of the second beam and the second part beam of the second beam form an illumination beam
