Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional viral and bacterial infection tests are used, then identification accuracy may be achieved, but the testing process is time-consuming and causes discomfort to individuals
Solution Approach 1:
The invention extracts only the essential diagnostic function from complex traditional testing procedures. By using a simple breath collection device that captures volatile organic compounds directly from exhaled air, it eliminates time-consuming sample preparation, culturing, and complex analysis steps while maintaining identification accuracy through selective chemical sensing.
Solution Approach 2:
The invention replaces mechanical and biological testing systems (swabs, throat scraping, laboratory culturing) with a chemical sensing system that detects volatile organic compounds in breath. This substitution enables rapid, non-invasive testing that provides results without the delays inherent in traditional methods while preserving diagnostic precision.
2Measurement precision
If traditional viral and bacterial infection tests are used, then identification may be achieved, but the testing process causes discomfort to individuals
Solution Approach 1:
The invention extracts the diagnostic capability from invasive procedures by focusing solely on analyzing volatile organic compounds in exhaled breath. This approach eliminates the need for throat swabs, nasal scraping, or blood draws, providing accurate identification while maintaining high comfort levels through completely non-invasive breath collection.
Solution Approach 2:
The testing system utilizes the body's natural breath emission as the sample source, requiring no active participation beyond normal breathing. Individuals simply exhale into the device, which automatically collects and analyzes the breath sample, making the process comfortable and easy to perform without medical intervention or discomfort.
3Device complexity
If viral and bacterial particles are directly analyzed, then the analysis process is simple, but the particles are too small to be identified by diffraction scanning
Solution Approach 1:
The invention employs a nested structure where antibody molecules first bind to viral or bacterial particles, forming larger complexes. Then additional antibody layers are applied to these complexes, creating progressively larger structures that nest within each other. This nested arrangement of antibodies around the target particles amplifies the size to detectable levels while maintaining the simplicity of the diffraction scanning analysis process.
Solution Approach 2:
The invention changes the physical parameter of particle size through chemical bonding. By applying multiple layers of antibodies that bind to the viral or bacterial particles, the effective size parameter of the target structure is increased from nanoscale (undetectable by diffraction) to micromscale (detectable by diffraction scanning), enabling accurate identification without complicating the analysis methodology.
