Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single device or a set of devices with the same type is used to detect the diffusible substance, then the device complexity is reduced, but the measurement precision and reliability of diffusion monitoring deteriorates due to limited monitoring coverage and inability to achieve accurate diffusion trends
Solution Approach 1:
The system segments the monitoring task by deploying multiple detection devices at different locations rather than using a single device. Each device independently monitors its local area, and the server collects and integrates data from all devices to reconstruct the overall diffusion trend, achieving both simplified individual device design and high overall monitoring precision
Solution Approach 2:
The system transitions from single-point monitoring to multi-dimensional spatial monitoring by distributing devices across different locations. The server uses time-synchronized data from multiple spatial points to calculate diffusion direction, speed, and concentration gradients, adding spatial dimensionality to the monitoring capability
2Measurement precision
If multiple devices with different types are applied to achieve comprehensive monitoring, then the measurement precision improves, but the device complexity and difficulty of time synchronization increases
Solution Approach 1:
The system employs devices with unified functionality for diffusion monitoring rather than integrating multiple different types of devices. Each device is designed to perform the same core function of detecting diffusible substances, which simplifies the overall system architecture while maintaining comprehensive monitoring capability through coordinated operation of identical devices
Solution Approach 2:
The system changes the operational parameters of devices to achieve time synchronization. By adjusting device clocks to a unified time standard and synchronizing data collection intervals, the system enables accurate temporal correlation of measurements from multiple devices without increasing device complexity
3Area of stationary object
If multiple devices are used without time synchronization, then the monitoring coverage increases, but the reliability of diffusion monitoring result deteriorates due to inaccurate diffusion trend determination
Solution Approach 1:
The server implements a feedback mechanism that collects time-stamped data from all devices, compares timestamps to detect synchronization deviations, and adjusts subsequent data collection timing accordingly. This feedback loop ensures that data from multiple devices remain temporally correlated, maintaining high reliability across expanded monitoring coverage
Solution Approach 2:
The system performs preliminary time synchronization calibration before actual diffusion monitoring begins. Devices are pre-configured with synchronized clocks and coordinated data collection schedules, ensuring that when monitoring starts, all devices are already time-aligned and ready to produce reliable correlated measurements across the entire monitoring area
