Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed wavelength filters are used in imaging devices, then the device structure is simple, but the transmission wavelengths are not suitable for different photographic subjects
Solution Approach 1:
The patent applies dynamics by making the filter wavelength variable rather than fixed. Each pixel's filter can dynamically change its transmission wavelength based on the photographic subject, allowing the imaging device to adapt to different subjects (flowers, landscapes, portraits, etc.) while maintaining a relatively simple overall structure without requiring multiple fixed-filter devices
Solution Approach 2:
The patent changes the parameter of filter transmission wavelength from a fixed value to a variable parameter that can be adjusted according to different photographic subjects. By controlling the wavelength parameter of each pixel's filter, the system achieves adaptability to various subjects while avoiding the complexity of multiple separate imaging devices
2Adaptability or versatility
If variable wavelength filters are used for each pixel, then adaptability to photographic subjects is improved, but device complexity increases
Solution Approach 1:
The patent makes each pixel's filter capable of performing multiple functions by enabling wavelength variation. Instead of having separate filters for different subjects, each filter can universally adapt to various photographic subjects by changing its transmission wavelength, reducing the need for multiple specialized components
Solution Approach 2:
The system implements self-service through automatic wavelength adjustment based on subject analysis. The control unit automatically determines the appropriate wavelength settings by analyzing photographic subject characteristics, eliminating the need for manual filter selection and reducing operational complexity
3Manufacturing precision
If manual filter selection is used, then device structure is simple, but image quality optimization is insufficient
Solution Approach 1:
The patent implements feedback by analyzing the captured image characteristics and automatically adjusting the filter wavelengths accordingly. The control unit receives image data, analyzes subject features, and adjusts the wavelength settings to optimize image quality, creating a closed-loop system that continuously improves imaging performance
Solution Approach 2:
The patent replaces manual mechanical filter selection with an automated control system that uses electronic signals to adjust filter wavelengths. This substitution of mechanical operation with electronic control achieves precise image quality optimization while maintaining system simplicity through software-based wavelength management
