Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing surveillance systems are used to capture and transmit data from remote locations, then data collection capability is improved, but device complexity and cost increase
Solution Approach 1:
The surveillance system is divided into independent remote sensor apparatus units, each capable of autonomous data collection and wireless transmission. Each unit contains its own processing unit, sensors, and transceiver, allowing modular deployment without complex interconnections between components.
Solution Approach 2:
The remote sensor apparatus is designed to autonomously collect sensor data, process it locally, and transmit it wirelessly without requiring complex external control systems. The device self-manages power, data acquisition, and communication functions.
2Reliability
If existing surveillance systems are deployed for remote monitoring, then surveillance capability is improved, but ease of operation deteriorates
Solution Approach 1:
The manual setup process is replaced with automated RFID-based pairing. The portable receiver automatically detects and pairs with remote sensor apparatus through RFID tags, eliminating the need for manual configuration and reducing setup complexity.
Solution Approach 2:
RFID tags serve as an intermediary mechanism between the portable receiver and remote sensor apparatus, enabling automatic identification and pairing without direct manual intervention. This simplifies the operational process for users.
3Measurement precision
If complex surveillance systems are implemented, then data accuracy is improved, but accessibility to frontline responders worsens
Solution Approach 1:
The system uses inexpensive, portable components including off-the-shelf sensors, RFID tags, and mobile devices that responders already possess. This eliminates the need for expensive specialized equipment while maintaining adequate data accuracy for first responder applications.
Solution Approach 2:
The system is designed to work with universal mobile devices (smartphones, tablets) that frontline responders already carry, rather than requiring specialized equipment. The portable receiver application can run on various mobile platforms, making the system accessible to all responders regardless of their specific device.
