Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If bio-peptide type sensors or amino acid sensors are used for odor detection, then the accuracy of odor molecule detection is improved, but the sensor becomes sensitive to temperature and humidity changes, leading to measurement errors
Solution Approach 1:
The patent introduces temperature and humidity control units as intermediary devices that mediate between the external environment and the sensor. These control units actively regulate the environmental conditions within the sensor chamber, creating a stable intermediate environment that protects the bio-peptide sensor from direct exposure to temperature and humidity variations, thereby maintaining high detection accuracy while eliminating environmental sensitivity issues
Solution Approach 2:
The patent creates an inert controlled environment within the sensor chamber by maintaining constant temperature and humidity levels. This controlled atmosphere acts as a protective barrier that isolates the sensor from harmful external environmental factors, allowing the bio-peptide sensor to operate at its full potential without interference from temperature and humidity changes
2Device complexity
If electrochemical sensors are used for odor detection, then the device structure is simpler, but the accuracy is low and durability lifespan is very short
Solution Approach 1:
The patent changes the fundamental parameter of sensor material from electrochemical to bio-peptide type, which fundamentally alters the detection mechanism. This parameter change enables high-precision odor detection while the added environmental control systems compensate for the increased complexity, achieving both high accuracy and improved durability
3Device complexity
If electrochemical sensors are used for odor detection, then the device structure is simpler, but the durability lifespan is very short
Solution Approach 1:
The patent changes the sensor material parameter from electrochemical to bio-peptide type, which fundamentally improves durability. The bio-peptide material is inherently more stable and longer-lasting than electrochemical sensors. The controlled environmental conditions further extend the lifespan by preventing degradation from temperature and humidity exposure
