Engineering Contradiction Analysis
1Use of energy by moving object
If conventional sensors are used for monitoring chemical and physical parameters, then measurement capability is provided, but power consumption is high and cost is high
Solution Approach 1:
The sensor is divided into multiple independent sensing elements on a single chip, each capable of detecting different chemical or physical parameters. This segmentation allows the system to distribute functionality across multiple small units, reducing the power consumption of individual elements while maintaining overall measurement capability through parallel operation of multiple sensors.
Solution Approach 2:
The sensor chip is designed as a universal platform that can detect multiple different chemical and physical parameters simultaneously using the same basic sensor architecture. By making the sensor system multi-functional, the invention eliminates the need for separate dedicated sensors for each parameter, thereby reducing overall power consumption and system cost while maintaining high reliability through standardized design.
2Speed
If conventional sensors are deployed in harsh environments, then monitoring is enabled, but response time is slow and stability is poor
Solution Approach 1:
The sensor utilizes multiple sensing dimensions or parameters simultaneously to detect target analytes, allowing the system to overcome interference from harsh environmental conditions by analyzing signals from different dimensional perspectives. This multi-dimensional approach enables faster response times while maintaining stability in challenging environments.
Solution Approach 2:
The sensor system incorporates feedback mechanisms that continuously monitor and adjust measurements based on environmental conditions and signal quality. This feedback loop compensates for environmental interference and maintains stable, accurate readings even in harsh settings, while the rapid feedback capability enables fast response times.
3Volume of moving object
If sensors are made smaller and lower power, then wireless integration is enabled, but manufacturing complexity increases
Solution Approach 1:
Multiple sensing elements and functional components are merged into a single integrated chip structure, allowing the system to achieve miniaturization without proportionally increasing fabrication complexity. By combining multiple functions into one unified platform, the invention reduces overall device size and power consumption while managing manufacturing complexity through standardized integration processes.
