Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional disaster response systems use communication infrastructure for information transmission, then information can be transmitted when communication networks are available, but information transmission fails or is delayed in environments with limited or unstable communication networks
Solution Approach 1:
The system segments communication into two independent modules: a first communication module for infrastructure-based communication and a second communication module for direct device-to-device communication. This segmentation allows the system to switch between communication methods based on environmental conditions, ensuring reliable information transmission whether communication infrastructure is available or not.
Solution Approach 2:
The measuring device is designed with multi-functional communication capabilities, able to perform both infrastructure-based communication (first communication module) and direct relay communication (second communication module). This universality enables the system to adapt to various communication environments, from stable networks to completely offline scenarios, maintaining reliable disaster information transmission across all conditions.
2Reliability
If conventional disaster response systems operate continuously to monitor disaster conditions, then real-time monitoring is achieved, but battery power is consumed excessively leading to operational failures during extended disasters
Solution Approach 1:
The control module implements periodic action by switching between deep sleep mode (low power consumption) and active monitoring mode (high reliability). The system periodically activates the sensing module and communication modules to check for alert conditions and transmit disaster information, rather than operating continuously. This periodic operation maintains monitoring reliability while dramatically reducing battery power consumption during extended disaster periods.
Solution Approach 2:
The system dynamically adjusts its operational state based on disaster conditions and communication availability. The control module transitions between deep sleep mode, sleep mode, and active mode, optimizing the balance between monitoring reliability and power consumption. This dynamic adaptation allows the system to maintain reliable disaster response capability while conserving battery power for extended operation.
3Speed
If the measuring device uses direct communication with control server, then information transmission is fast when infrastructure is available, but communication fails when infrastructure is unavailable
Solution Approach 1:
Other measuring devices serve as intermediaries for relay communication. When the control server is inaccessible through infrastructure communication, the second communication module transmits alert information to nearby measuring devices, which relay the information through the network until it reaches a device with server access. This intermediary mechanism maintains communication availability while preserving fast information transmission through the relay network.
4Reliability
If the measuring device activates both communication modules continuously, then communication coverage is maximized, but power consumption increases significantly
Solution Approach 1:
The control module dynamically controls the activation state of communication modules based on operational needs. In deep sleep mode, both modules are deactivated to minimize power consumption. In sleep mode, the second communication module is activated for low-power direct communication. In active mode, both modules are activated to maximize communication coverage when disaster conditions require comprehensive communication. This dynamic control maintains communication reliability while optimizing power consumption.
Solution Approach 2:
Different communication modules are activated in different operational contexts. The first communication module (infrastructure-based) is activated when server communication is needed, while the second communication module (direct communication) is activated for peer-to-peer relay. This localized activation of communication capabilities ensures comprehensive coverage is only used when necessary, reducing overall power consumption while maintaining communication reliability.
