Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If luminol is used to detect blood, then blood detection capability is improved, but blood contamination occurs
Solution Approach 1:
The patent uses an intermediary substance (such as a fluorescent marker or contrast agent) that binds to blood without contaminating it permanently. This intermediary allows detection through optical properties while maintaining the integrity of the blood sample for subsequent analysis or natural processes.
Solution Approach 2:
The patent replaces chemical methods (luminol) with optical or electromagnetic detection methods. By using cameras, sensors, or imaging technology to detect blood's optical properties (color, reflectivity, fluorescence), the system achieves detection without chemical contamination.
2Ease of operation
If color-based blood detection is used, then detection simplicity is improved, but detection accuracy deteriorates for color deficient users
Solution Approach 1:
The detection device is designed to serve multiple user types simultaneously. It provides both simple color-based detection for users with normal vision and alternative detection modes (such as grayscale, enhanced contrast, or pattern recognition) for color-deficient users, making the system universally accessible.
Solution Approach 2:
The patent transitions from relying solely on color perception to using additional dimensions of detection such as brightness intensity, texture patterns, or spectral analysis. This allows color-deficient users to detect blood through non-color properties while maintaining detection simplicity.
3Adaptability or versatility
If blood detection is performed in low light conditions, then operational flexibility is improved, but detection reliability deteriorates
Solution Approach 1:
The device performs preliminary actions to compensate for low light conditions before detection occurs. This includes activating illumination sources (LEDs, flashlights), adjusting sensor sensitivity, or pre-processing images to enhance contrast. These preliminary steps ensure reliable detection regardless of ambient lighting conditions.
Solution Approach 2:
The patent dynamically changes detection parameters based on lighting conditions. In low light, the system adjusts exposure time, gain, illumination intensity, or switches to infrared/night vision modes. These parameter changes maintain detection reliability across varying environmental conditions while preserving operational flexibility.
