Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-vendor solution is used for sensor networks, then system integration and control are simplified, but access to sensors and data is restricted, limiting open usage and IoT integration
Solution Approach 1:
The patent introduces a gateway device as an intermediary between the sensor network and external systems. This gateway acts as a mediator that enables multiple applications to access sensor data without direct connections to each sensor, thereby promoting open usage while maintaining manageable system integration through a centralized interface
2Area of stationary object
If remote sensor devices are deployed in distributed locations, then monitoring coverage is expanded, but configuration management and status monitoring become more difficult
Solution Approach 1:
The patent implements a feedback mechanism where the gateway device receives configuration information from applications, transmits it to remote sensor devices, and then receives status information back from the sensors to confirm proper configuration. This closed-loop feedback system enables effective management of distributed sensors by providing real-time verification of configuration status
3Adaptability or versatility
If configuration information is transmitted to remote sensor devices, then sensor functionality is enhanced, but transmission errors may occur due to remote locations
Solution Approach 1:
The gateway device transmits configuration information to remote sensor devices and receives status information in response to verify successful configuration. This feedback mechanism allows the system to detect transmission errors and retry or correct configurations, thereby enhancing reliability of configuration transmission to remotely deployed sensors
Solution Approach 2:
The system transmits configuration information to sensor devices before actual operation begins. This preliminary configuration action ensures that sensors are properly set up and ready for operation, preventing functional errors that would occur if configuration were delayed until deployment
4Adaptability or versatility
If multiple applications access sensor data through a centralized system, then data sharing and integration are improved, but system complexity and data management burden increase
Solution Approach 1:
The gateway device serves as a centralized intermediary that manages data from multiple sensor devices and provides it to multiple applications. This intermediary approach enables improved data sharing and integration among applications while the gateway handles the complexity of data management, filtering, and distribution, thereby preventing the complexity burden from directly affecting individual applications
