Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing monitoring systems are used to detect eye drop administration, then detection capability is provided, but the systems are either not sufficiently developed, expensive, or lack accuracy in determining if drops reach the eye
Solution Approach 1:
The patent uses bioluminescent dye that emits light of a specific wavelength range when excited, creating a detectable optical signal. The photo sensor detects this specific wavelength range to confirm eye drop administration. This color/wavelength-based detection method provides high measurement precision while keeping the device relatively simple and cost-effective.
Solution Approach 2:
The patent introduces an optical filter as an intermediary component that selectively transmits only the predefined wavelength range emitted by the bioluminescent dye to the photo sensor. This intermediary element enhances detection accuracy by blocking other wavelengths and ensures reliable detection while maintaining system simplicity.
2Reliability
If existing monitoring systems are used to detect eye drop administration, then detection capability is provided, but the systems are expensive
Solution Approach 1:
The patent employs inexpensive components including a bioluminescent dye, a photo sensor, and an optical filter that can be integrated into affordable eyewear apparatus. This approach replaces expensive existing monitoring systems with a cost-effective solution that maintains high detection reliability through the specific wavelength detection mechanism.
Solution Approach 2:
The bioluminescent dye emits light at a specific wavelength range when excited, providing a clear and reliable detection signal. This optical property enables reliable detection using simple and inexpensive photo sensors and optical filters, significantly reducing system cost while maintaining high reliability.
3Measurement precision
If bioluminescent dye with predefined wavelength range is used, then detection accuracy is improved, but device complexity increases due to additional components
Solution Approach 1:
The patent utilizes the bioluminescent dye's emission at a specific wavelength range as the core detection mechanism. By matching the optical filter and photo sensor to this specific wavelength, the system achieves high detection precision. The complexity is minimized by integrating these components into a compact eyewear apparatus rather than a complex standalone system.
Solution Approach 2:
The optical filter serves as an intermediary that simplifies the detection system by selectively transmitting only the relevant wavelength range to the photo sensor. This intermediary component enhances precision while keeping the overall apparatus relatively simple by blocking unnecessary wavelengths and reducing the need for complex signal processing.
