Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional routers are used in mission critical facilities, then device complexity is reduced, but signal transmission reliability deteriorates due to metal obstructions
Solution Approach 1:
The patent introduces an intelligent gateway as an intermediary device between sensors and the central system. This gateway performs local data analysis and filtering, determining which data packets need transmission. The gateway includes a processor that analyzes sensor data and a communication module that selectively transmits only relevant data, acting as a mediator that reduces unnecessary transmissions through metal obstructions while maintaining system reliability.
Solution Approach 2:
The intelligent gateway performs preliminary data analysis and filtering before transmission. The processor analyzes incoming sensor data, determines whether the data meets transmission criteria, and pre-processes the data accordingly. This preliminary action prevents unnecessary transmission attempts through metal obstructions, improving signal reliability while managing device complexity.
2Loss of information
If data from all sensors is transmitted continuously, then data completeness is improved, but loss of time increases due to unnecessary transmissions
Solution Approach 1:
The intelligent gateway implements a feedback mechanism where the processor continuously monitors sensor data and compares it against predefined thresholds or patterns. Based on this feedback analysis, the gateway determines whether data packets meet transmission criteria. This feedback-driven approach ensures that only meaningful data is transmitted, maintaining data completeness while eliminating wasteful transmission time.
Solution Approach 2:
Instead of transmitting all sensor data continuously (excessive action), the intelligent gateway transmits only the necessary subset of data that meets specific criteria (partial action). The processor filters data packets based on relevance, urgency, or change thresholds, transmitting only what is needed. This partial transmission approach maintains data completeness for critical information while significantly reducing overall transmission time.
3Measurement precision
If multiple sensors are integrated in the gateway, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The intelligent gateway is designed as a universal platform that can integrate multiple types of sensors (temperature, humidity, pressure, air quality, motion) through standardized interfaces. The processor is configured to handle various sensor data formats and protocols, providing multi-functional environmental monitoring capabilities. This universal design achieves comprehensive measurement precision while managing complexity through standardized architecture.
Solution Approach 2:
The patent combines multiple sensor types and their processing functions into a single integrated gateway device. Instead of having separate devices for each sensor type, the gateway merges temperature sensors, humidity sensors, pressure sensors, and other environmental sensors into one unit with a common processor and communication interface. This merging achieves comprehensive environmental monitoring precision while reducing overall system complexity.
