Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If planar light-diffraction elements are arranged in sequence for optical computing, then optical computing capability is improved, but positional relationship stability deteriorates
Solution Approach 1:
Multiple planar light-diffraction elements are integrated into a single tubular body structure, merging what would otherwise be separate components into one unified housing. This integration ensures that the elements maintain their precise positional relationships while enabling multi-stage optical computing operations to be performed in sequence.
Solution Approach 2:
The planar light-diffraction elements are nested within the tubular body, with each element positioned at a specific depth along the optical path. This nested arrangement allows multiple elements to coexist in a compact configuration while maintaining stable positional relationships, as each element is contained within the protective and structurally rigid tubular housing.
2Measurement precision
If nanometer-level positional precision is required for light-diffraction elements, then optical computing accuracy is improved, but sensitivity to positional deviation worsens
Solution Approach 1:
The tubular body is designed with features that preemptively protect against positional deviations before they can affect optical computing accuracy. The rigid tubular structure provides mechanical support that prevents elements from shifting, while the integrated design ensures that nanometer-level precision is maintained throughout operation, cushioning against environmental factors that could cause deviation.
3Power
If multiple planar light-diffraction elements are used for sequential optical computing, then computational power is improved, but difficulty in maintaining positional relationship worsens
Solution Approach 1:
The tubular body merges the positioning function for multiple light-diffraction elements into a single structural component. By providing a unified housing with pre-defined positioning features, the system simplifies the maintenance of positional relationships while enabling multiple elements to work together for enhanced computational power through sequential optical processing.
