Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional laboratory culture systems are used for diagnosis, then high sensitivity is achieved, but the processing time becomes relatively long and the system requires full microbiology laboratory support
Solution Approach 1:
The patent extracts the diagnostic function from complex laboratory culture systems by detecting volatile compounds directly from breath samples. This extraction allows diagnosis to be performed without requiring full microbiology laboratory infrastructure, thereby reducing processing time while maintaining diagnostic capability through identification of bacterial volatile compound signatures
Solution Approach 2:
The patent uses volatile compounds as an intermediary substance that carries diagnostic information from the infection site to the detection system. These volatiles serve as a mediator that can be detected externally through breath analysis, eliminating the need for direct sample culture and reducing processing time while preserving diagnostic sensitivity
2Measurement precision
If laboratory based systems are used, then accurate diagnosis is achieved, but the cost becomes high and the systems are not portable
Solution Approach 1:
The patent extracts the essential diagnostic function from complex laboratory systems by focusing solely on volatile compound detection. This extraction enables the development of simpler, portable devices that can perform accurate diagnosis without requiring full laboratory infrastructure, thereby reducing cost and improving portability while maintaining diagnostic accuracy
Solution Approach 2:
The patent creates a simplified copy of the diagnostic process by detecting volatile compound signatures that replicate the information obtained from complex laboratory cultures. This copying approach allows accurate diagnosis to be performed with simple, portable devices rather than requiring expensive, complex laboratory systems
3Measurement precision
If invasive sampling methods are used, then diagnostic accuracy is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent uses breath as an intermediary that provides access to diagnostic information without requiring invasive procedures. Volatile compounds produced by bacteria serve as mediators that can be sampled non-invasively through breath collection, thereby maintaining diagnostic accuracy while dramatically improving ease of operation
Solution Approach 2:
The patient's own breath serves as the sampling medium, eliminating the need for invasive procedures performed by medical staff. The body naturally expels volatile compounds through breathing, allowing simple collection of diagnostic samples without requiring throat swabs or other invasive techniques, thereby improving ease of operation while maintaining diagnostic accuracy
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient, cost-effective, and portable diagnosis and treatment monitoring of respiratory tract infections by identifying unique volatile compound profiles indicative of bacterial infections, facilitating timely intervention.
Implementation Method 1
exposing a gaseous sample (a breath sample or a headspace sample) comprising volatile compounds (VCs) to a sensor responsive to interaction with the volatile compounds; detecting/measuring an output signal received from the sensor correlating with an interaction between the VCs and the sensor
Implementation Method 2
VCs are transported from different organs via blood to the lungs and subsequently excreted from the lungs by diffusing across the pulmonary alveolar membrane and exhaled via the breath
