Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single light-sensing element is used to measure light fields at different distances sequentially, then the device complexity is reduced, but the measurement precision deteriorates due to time and vibration-induced errors
Solution Approach 1:
The patent divides the single measurement function into multiple parallel measurement channels, each with its own light-sensing element. By segmenting the measurement task across four simultaneous measurement paths at different distances, the system eliminates sequential measurement errors while maintaining manageable device complexity through modular architecture
Solution Approach 2:
The patent transitions from one-dimensional sequential measurement (single element moving to different positions) to four-dimensional simultaneous measurement (multiple elements at different positions, orientations, and distances). This dimensional expansion allows parallel capture of light field data, eliminating time-induced errors while the beam splitting device manages the complexity of coordinating multiple sensing elements
2Measurement precision
If multiple light-sensing elements are used to simultaneously measure light fields at different distances, then the measurement precision is improved by eliminating time and vibration errors, but the device complexity increases
Solution Approach 1:
The beam splitting device serves as an intermediary that receives the incoming light beam and distributes it to multiple light-sensing elements simultaneously. This intermediary component simplifies the overall system architecture by providing a centralized light distribution mechanism, reducing the complexity that would otherwise arise from requiring multiple independent light sources or complex optical paths
Solution Approach 2:
The beam splitting device performs multiple functions: it divides the light beam into separate paths, directs each path to different sensing elements, and enables simultaneous measurement at various distances. This multi-functionality consolidates what would otherwise require separate components, thereby improving measurement precision while controlling device complexity through a versatile single component
3Device complexity
If sequential measurement at different distances is performed, then the device structure is simplified, but the measurement time increases leading to productivity reduction
Solution Approach 1:
The patent implements continuous simultaneous measurement across four different distances using multiple light-sensing elements operating in parallel. This continuous parallel action eliminates the interruptions and sequential delays inherent in moving a single sensor between positions, thereby increasing measurement speed and productivity while the beam splitting device maintains structural organization
4Device complexity
If a single light-sensing element moves to different positions for measurement, then the device structure is simplified, but vibration-induced measurement errors increase
Solution Approach 1:
The patent segments the single moving sensor into multiple fixed sensors positioned at different distances simultaneously. This segmentation eliminates the need for mechanical movement and associated vibrations, as each sensing element remains stationary in its optimal position, thereby improving measurement accuracy while the modular beam splitting structure maintains device simplicity
