Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If mechanical sights or optical sights are used with manual adjustment knobs, then the device complexity is reduced, but the reliability deteriorates due to mechanical wear causing aiming errors
Solution Approach 1:
The patent replaces mechanical adjustment knobs with an electronic control system that includes a processor, display unit, and electronic adjustment mechanisms. The sight now uses electronic signals and software algorithms to adjust reticle position and magnification, eliminating mechanical wear and improving reliability while maintaining ease of operation.
Solution Approach 2:
The sight incorporates automatic calibration functionality where the system performs self-adjustment based on environmental sensor data and ballistic calculations. The processor automatically compensates for environmental factors and bullet trajectory variations without requiring manual intervention, thereby maintaining high reliability without increasing complexity.
2Ease of operation
If night vision function is added to enhance night shooting capability, then the ease of operation improves, but the measurement precision deteriorates due to blurred boundaries and decreased brightness distinction
Solution Approach 1:
The patent introduces a display unit that acts as an intermediary between the night vision sensor and the shooter. The display presents processed visual information with enhanced contrast and artificially generated targeting aids such as illuminated reticles and range indicators, allowing the shooter to maintain precision while benefiting from night vision capabilities.
Solution Approach 2:
The night vision system employs pseudocolor processing and brightness enhancement techniques to improve target boundary distinction. By converting grayscale night vision images into color-coded representations with enhanced contrast, the system maintains measurement precision while improving ease of operation in low-light conditions.
3Measurement precision
If magnification adjustment function is added to observe target clearly, then the measurement precision improves, but the ease of operation deteriorates due to requiring manual adjustment during aiming
Solution Approach 1:
The patent implements dynamic magnification adjustment where the magnification level changes automatically based on target distance and type detected by sensors and image processing. The system dynamically adapts the magnification without requiring manual intervention, maintaining measurement precision while improving ease of operation during aiming.
Solution Approach 2:
The sight incorporates feedback mechanisms where the display unit provides real-time information about target distance, recommended magnification levels, and reticle positioning. This feedback loop allows the system to automatically adjust magnification to optimal levels, improving both measurement precision and ease of operation by eliminating the need for manual adjustment during aiming.
4Manufacturing precision
If trial and correction calibration method is used for new sight installation, then the manufacturing precision is improved, but the loss of time increases due to repeated shooting and adjustment
Solution Approach 1:
The patent incorporates preliminary environmental sensing and ballistic parameter input during the calibration process. The system pre-calculates expected bullet trajectories based on environmental conditions and sight mounting parameters, allowing for faster convergence to accurate calibration settings and reducing the time required while maintaining precision.
Solution Approach 2:
The calibration process is enhanced by replacing purely mechanical trial-and-error adjustment with an electronic system that uses sensor data, ballistic calculations, and automated reticle positioning. The processor rapidly computes optimal calibration settings based on environmental parameters and sight installation measurements, significantly reducing calibration time while maintaining or improving calibration accuracy.
5Reliability
If environmental factors are considered in calibration, then the reliability improves, but the device complexity increases due to additional sensors and calculations
Solution Approach 1:
The patent implements a multi-functional processor that handles multiple tasks including environmental data acquisition, ballistic calculations, reticle positioning, and display control within a single integrated unit. This universal approach allows the system to consider multiple environmental factors and perform complex calculations without proportionally increasing device complexity, thereby improving reliability while maintaining reasonable system complexity.
