Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple optical elements are used to process light radiation, then the spatial phase of the light can be modified, but the positioning precision requirement increases to micron level
Solution Approach 1:
The patent combines multiple optical elements into a single integrated optical element that performs multiple spatial phase modifications. Instead of using separate elements that require precise positioning relative to each other, the invention integrates all phase modification functions into one element, eliminating alignment requirements between multiple components.
Solution Approach 2:
The patent creates a single optical element that performs multiple functions - it modifies the spatial phase of light radiation at multiple different locations simultaneously. This multi-functional element replaces what would traditionally require multiple separate optical elements, each performing a single phase modification function.
2Reliability
If multiple optical elements are used with precise positioning, then effective light processing is achieved, but assembly time increases
Solution Approach 1:
By merging multiple optical elements into one integrated element, the patent eliminates the time-consuming assembly process of positioning multiple components. The single element approach removes all alignment and positioning steps that would be required when assembling multiple separately manufactured optical elements.
3Reliability
If multiple optical elements are positioned relative to each other, then spatial phase modifications are achieved, but the system becomes sensitive to shocks and vibrations
Solution Approach 1:
The patent merges multiple optical elements into a single rigid integrated element, eliminating the mechanical connections and relative positioning requirements between multiple components. This integration removes the system's sensitivity to shocks and vibrations that would affect the relative positions of multiple separate elements.
4Manufacturing precision
If optical elements are precisely positioned, then light processing accuracy is maintained, but manufacturing cost increases
Solution Approach 1:
The patent combines multiple precision-manufactured optical elements into a single element, eliminating the need for expensive precision positioning mechanisms and alignment procedures. The single integrated element approach reduces manufacturing complexity and cost while maintaining the required optical processing accuracy.
