Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a photoelectric converter detects signals across a wide wavelength band to detect multiple disease conditions, then the detection capability is improved, but the amount of information increases excessively
Solution Approach 1:
The patent applies a variable spectroscopic element that can dynamically change its transmission wavelength in response to control signals. This dynamic adjustment allows the system to adapt the wavelength band being monitored based on the currently suspected disease condition, thereby maintaining high detection capability while preventing information overload by only capturing relevant wavelength data at any given time
Solution Approach 2:
The system changes the parameter of wavelength transmission by using a variable spectroscopic element whose transmission characteristics can be adjusted. By changing the transmission wavelength parameter according to the identified disease condition, the system optimizes the detected information to match the diagnostic needs, reducing unnecessary data while maintaining detection versatility
2Measurement precision
If light rays of multiple wavelengths are transmitted at a short wavelength interval to improve diagnosis accuracy, then the measurement precision is improved, but the amount of data increases
Solution Approach 1:
The patent applies local quality by setting a shorter wavelength interval only within the specific wavelength band range that corresponds to the identified disease condition, while using a longer wavelength interval outside this range. This localized high-resolution monitoring ensures diagnosis accuracy for the relevant disease while reducing overall data generation by coarser sampling in irrelevant wavelength regions
3Productivity
If a variable spectroscopic element is used to adjust wavelength transmission, then the efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by using a single variable spectroscopic element that can perform multiple functions: it can adjust transmission wavelength, select wavelength bands, and control light transmission intensity. This multi-functional component replaces what would otherwise require multiple separate optical components, thereby improving system efficiency while minimizing the increase in device complexity
