Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If Bayer matrix color filter mode is used, then color imaging is achieved, but image resolution is greatly reduced
Solution Approach 1:
The patent divides the imaging system into multiple independent monochrome imaging channels, each capturing the entire scene at full resolution. By segmenting the color filtering function across multiple sensors rather than using a Bayer matrix on a single sensor, each sensor maintains full resolution while the system as a whole achieves color imaging capability.
Solution Approach 2:
The patent combines multiple full-resolution monochrome images captured by separate sensors to produce a final color image. By merging the data from multiple independent imaging channels that each capture complete spatial information, the system achieves both high resolution and color capability without the resolution loss inherent in Bayer matrix interpolation.
2Reliability
If additional lenses are added to correct chromatic aberration, then image quality is improved, but system volume increases
Solution Approach 1:
The patent extracts and eliminates the problematic element of chromatic aberration by using monochrome sensors that do not suffer from this optical defect. By removing the color filtering layer that causes chromatic aberration in conventional systems, the need for additional corrective lenses is eliminated, thereby reducing system volume while maintaining or improving image quality.
Solution Approach 2:
Instead of adding corrective lenses to fix chromatic aberration in a color imaging system, the patent inverts the approach by using monochrome sensors that inherently avoid chromatic aberration, then synthesizing color information through computational methods rather than optical correction.
3Reliability
If additional lenses are added to correct chromatic aberration, then image quality is improved, but manufacturing cost increases
Solution Approach 1:
The patent removes the source of chromatic aberration by using monochrome sensors without color filter arrays, thereby eliminating the need for expensive achromatic correction lenses. This extraction of the problematic color filtering component reduces both the optical complexity and manufacturing cost while maintaining image quality through alternative color synthesis methods.
Solution Approach 2:
The patent replaces expensive precision optical components (achromatic lenses) with more affordable monochrome sensors and computational processing. By substituting costly optical correction with electronic/image processing solutions, the system achieves comparable or superior image quality at lower manufacturing cost.
