Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional movable mirror devices are provided as separate devices with analog amplifiers and external target hardware, then the system can be manufactured and assembled, but calibration is required for each combination of scanning device and target hardware, limiting flexibility and requiring recalibration when hardware is replaced
Solution Approach 1:
The patent combines the position sensor device, processing device, and analog-to-digital converter into a single unitary movable mirror device. This integration eliminates the need for external target hardware and analog amplifiers, allowing the device to be directly connected to digital systems. The merging of these components resolves the technical contradiction by enabling the device to work with different target hardware without recalibration, as all necessary processing functions are contained within the unitary device itself.
Solution Approach 2:
The unitary movable mirror device incorporates multiple functions within a single device: position sensing, signal amplification, analog-to-digital conversion, and processing. This multi-functionality allows the device to interface directly with various digital target hardware systems without requiring external components or calibration for each combination, thereby improving adaptability while managing complexity through functional integration.
2Ease of manufacture
If analog signals are transmitted externally to target hardware for digitization and processing, then the system architecture is modular and manufacturable, but the device requires calibration for each hardware combination and is difficult to replace without recalibration
Solution Approach 1:
By merging the position sensor, processing device, and ADC into a single unitary device, the patent enables the device to be manufactured as an integrated component with all necessary functions built-in. This integration maintains ease of manufacture through standardized production processes while simultaneously improving adaptability, as the complete functional unit can be replaced without recalibration since it contains all processing capabilities internally.
Solution Approach 2:
The unitary device performs all signal processing and calibration functions internally before outputting digital signals. By incorporating the processing device and ADC within the movable mirror device itself, the calibration and processing actions are performed preliminarily within the device, eliminating the need for external calibration when replacing the device with different target hardware.
3Adaptability or versatility
If the movable mirror device is integrated as a unitary device with on-board processing and ADC, then flexibility and ease of replacement are improved, but the device complexity increases
Solution Approach 1:
The patent applies merging by integrating the position sensor device, processing device, and ADC into a single unitary movable mirror device. While this increases internal component integration, it resolves the adaptability issue by eliminating external dependencies. The complexity is managed through functional integration that reduces the overall system complexity by removing external hardware interfaces and calibration requirements.
Solution Approach 2:
The unitary device performs all necessary signal processing, conversion, and calibration functions internally through its integrated processing device and ADC. This self-service capability allows the device to operate independently without external target hardware or calibration procedures, improving flexibility while the integrated design manages complexity through autonomous functionality.
