Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired sensors are used to monitor bioprocess parameters, then measurement reliability is improved, but device complexity and scalability are worsened due to extensive wiring requirements
Solution Approach 1:
The patent extracts the sensing function from the wired connection system by implementing wireless sensors that can independently measure bioprocess parameters (temperature, pressure, pH, dissolved oxygen) and transmit data without physical wire connections to the reader, thereby maintaining measurement reliability while eliminating wiring complexity
Solution Approach 2:
The wireless sensor system provides multi-functionality by integrating multiple sensing capabilities (temperature, pressure, pH, dissolved oxygen measurement) into a single wireless platform that can be deployed across various bioprocess applications without requiring separate wired connections for each parameter or location
2Reliability
If wired connections are used to connect sensors to the reader, then data transmission reliability is improved, but adaptability and positioning flexibility are worsened
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system that uses electromagnetic fields for data transmission, allowing sensors to be positioned flexibly at any location within the bioprocess environment without being constrained by physical wire routing while maintaining reliable data transmission
3Quantity of substance
If multiple wired sensors are deployed for comprehensive monitoring, then measurement coverage is improved, but scalability and ease of operation are worsened due to increased wiring requirements
Solution Approach 1:
The patent segments the monitoring system into independent wireless sensor units that can be individually deployed and configured at different bioprocess locations, allowing the system to scale by simply adding more wireless sensors without requiring complex wiring infrastructure or system reconfiguration
4Adaptability or versatility
If wireless sensors with power sources are used, then positioning flexibility is improved, but device complexity is worsened due to power source requirements
Solution Approach 1:
The patent implements periodic action by using duty cycling where the wireless sensor alternates between active measurement/transmission modes and low-power sleep modes, allowing the sensor to maintain positioning flexibility with integrated power sources while managing power consumption through periodic operation rather than continuous operation
