Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex detection techniques and costly apparatus are used to detect fluorescence, then detection precision and reliability are improved, but device complexity and cost increase
Solution Approach 1:
The patent employs disposable test tubes with integrated fluorophores instead of expensive, complex detection apparatus. The test tubes are inexpensive, single-use items that eliminate the need for costly equipment like charge-coupled devices and fluorometers, while still providing sufficient detection precision for educational and low-resource settings.
Solution Approach 2:
The patent extracts the fluorescence detection function from complex detection equipment and transfers it to the test tube itself by incorporating fluorophores directly into the test tube walls. This allows the test tube to emit fluorescence when exposed to UV light, enabling detection without expensive apparatus.
2Difficulty of detecting and measuring
If advanced equipment is used for fluorescence detection, then measurement capability is improved, but ease of operation deteriorates
Solution Approach 1:
The disposable test tubes with integrated fluorophores require no complex operation or calibration. Users simply add the sample to the test tube and observe under UV light, making the process as simple as using a disposable container while maintaining detection capability.
Solution Approach 2:
The test tube performs the detection function autonomously through its integrated fluorophores that automatically emit light when exposed to UV illumination, eliminating the need for complex equipment operation, calibration, or maintenance by the user.
3Device complexity
If static detection methods are used, then device simplicity is maintained, but adaptability deteriorates
Solution Approach 1:
The patent uses fluorophores with different emission characteristics that respond to various conformational states of biomolecules. By selecting appropriate fluorophores, the same simple test tube design can detect different molecular conformations, enzymatic activities, and binding events, providing versatility without increasing device complexity.

Function Achieved in This Case
Enables direct, cost-effective visualization and monitoring of fluorescence changes in biomolecules, allowing for the study of conformational states and enzymatic processes, even in educational settings, by allowing users to observe fluorescence changes with the naked eye or through imaging, facilitating the study of biomolecular dynamics and interactions.
Implementation Method 1
The test tubes include fluorophore containing compositions, which emit light at longer wavelengths upon excitation by light at shorter wavelengths
Implementation Method 2
The filter is configured to transmit light within an emission spectral pattern of the fluorophores and attenuate light within an excitation spectral pattern of the light source
