Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional processing technologies are used to form riblet structures, then the basic riblet shape can be achieved, but the precision of shape control and optical characteristics is insufficient
Solution Approach 1:
The light source is divided into multiple processing lights with different incident directions, intensities, phases, and polarizations. Each processing light contributes to forming specific portions of the interference fringe pattern, enabling precise control over the riblet shape and optical characteristics through independent adjustment of each light component's parameters.
Solution Approach 2:
Different regions of the object surface receive processing lights with locally optimized characteristics. By adjusting the intensity, phase, and polarization of individual processing lights, the interference fringe pattern is tailored to produce the desired riblet shape and optical properties in specific areas, achieving high manufacturing precision.
2Object-generated harmful factors
If conventional processing methods are used, then the processing process is simpler, but the reduction of frictional resistance and turbulent frictional resistance is suboptimal
Solution Approach 1:
The invention changes multiple parameters of the processing lights simultaneously, including intensity ratios, phase differences, and polarization states. These parameter adjustments modify the interference fringe pattern to precisely control the riblet formation process, optimizing both the shape precision and the resulting friction reduction performance.
Solution Approach 2:
The processing system uses a composite approach by combining multiple processing lights with different optical characteristics (intensity, phase, polarization) to create a composite interference pattern. This composite light field enables simultaneous control over both the geometric shape and optical characteristics of the formed riblet structure.
3Manufacturing precision
If multiple processing lights with controlled differences are used, then the riblet shape and optical characteristics can be precisely adjusted, but the optical system becomes more complex
Solution Approach 1:
The optical system segments the light source into multiple processing lights, each with independently controllable characteristics. This segmentation allows precise adjustment of optical characteristics through parameter control of individual light components rather than requiring complex interaction of multiple optical elements.
Solution Approach 2:
Each processing light serves multiple functions by simultaneously contributing to the interference pattern formation, providing spatial distribution, and enabling optical characteristic control. This multi-functionality reduces the need for separate optical components for each function, thereby managing system complexity.
