Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional microbiological methods are used for diagnosis, then identification of microbes can be achieved, but the diagnosis time is extended to 2-3 days and costs increase
Solution Approach 1:
The patent replaces traditional mechanical microbiological cultivation methods with a fluorescent sensing system. LCO probes directly detect microbial peptides through fluorescent signal changes, eliminating the need for time-consuming bacterial cultivation and biochemical testing, thus reducing diagnosis time from 2-3 days to a much shorter period while maintaining identification accuracy
Solution Approach 2:
The patent introduces LCO (luminescent conjugated oligothiophenes) as an intermediary substance that binds to microbial peptides and produces detectable fluorescent signals. This intermediary enables direct detection of microbes without requiring their cultivation, solving the time-loss problem while preserving measurement precision
2Measurement precision
If traditional microbiological methods are used, then microbial identification can be performed, but the cost of treatment increases due to extensive testing
Solution Approach 1:
The patent extracts only the essential diagnostic function from the complex traditional microbiological testing battery. By using LCO probes that directly bind to microbial peptides, the system eliminates unnecessary extensive biochemical tests, thereby reducing treatment costs while maintaining diagnostic accuracy
Solution Approach 2:
The patent employs disposable LCO probes that are inexpensive and single-use. These probes provide rapid detection without requiring expensive equipment or lengthy procedures, thus reducing the overall cost of treatment while preserving measurement precision
3Ease of operation
If wide spectrum acting drugs are used to treat patients, then patients can be treated with generic protocols, but antibiotic resistance develops and complications occur
Solution Approach 1:
The patent implements feedback by providing rapid, accurate identification of the specific causative microbe through fluorescent detection. This feedback enables physicians to prescribe targeted antibiotics based on actual pathogen identity rather than using generic wide-spectrum protocols, thereby preventing antibiotic resistance while maintaining ease of operation through database-comparative diagnosis
4Measurement precision
If methods requiring microbe cultivation are used, then identification can be performed, but the process becomes time-consuming and expensive
Solution Approach 1:
The patent replaces the mechanical process of microbe cultivation and amplification with a direct fluorescent detection system. LCO probes bind to microbial peptides present in the sample, producing immediate detectable signals without requiring bacterial growth, thus dramatically increasing diagnostic speed while maintaining identification 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
This method significantly reduces the time and cost of diagnosis, allows for the identification of uncultivable bacteria, and provides a more accurate analysis by using LCOs to detect specific bacterial components, thereby improving the precision and speed of microbial infection diagnosis.
Implementation Method 1
Luminescent Conjugated Oligothiophenes (LCOs) are a group of fluorophores that experience a change in molecule geometry when interacting with a target. Target binding induces a change in fluorescence signal, producing an optical signature that is unique to the target.
