Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If highly sensitive ATP detection systems are used, then detection sensitivity is improved, but background noise interference increases leading to false results
Solution Approach 1:
The patent introduces UV-blocking filters and light-blocking covers as intermediary elements between the external environment and the luminescent test system. These intermediaries selectively block harmful UV radiation and ambient light while allowing the luminescent signal to pass through, thereby reducing background noise interference without compromising detection sensitivity
Solution Approach 2:
The patent extracts and removes the harmful UV radiation component from the ambient light environment by using UV-blocking filters. This selective removal of the harmful wavelength component allows the beneficial luminescent signal to be detected without interference from UV-induced background noise
2Illumination intensity
If transparent test vials are used to allow luminescence detection, then light transmission is improved, but UV radiation penetration increases causing interference
Solution Approach 1:
The patent employs composite material construction for the test vial system, combining transparent materials that allow luminescence transmission with integrated UV-blocking filters. This composite approach maintains the necessary optical transparency for signal detection while incorporating UV protection to prevent harmful radiation penetration
Solution Approach 2:
The patent applies UV-blocking properties locally at specific interfaces where UV radiation would cause interference, such as at the vial walls or cover interfaces. This localized application of UV-blocking quality allows the rest of the system to maintain high transparency for luminescence detection
