Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed transmission frequency is used for location information, then the system complexity is reduced and energy consumption is lowered, but the accuracy of danger level calculation deteriorates during dynamic natural disasters
Solution Approach 1:
The patent implements dynamic transmission frequency adjustment based on real-time danger levels. The management apparatus changes the transmission interval from fixed to variable, where the interval is shortened when danger levels increase and extended when danger levels decrease. This dynamic adaptation resolves the contradiction by allowing accurate danger level calculation during disasters while maintaining simple fixed-frequency operation during normal conditions.
Solution Approach 2:
The patent changes the transmission parameter (time interval) based on the danger level parameter. When the danger level exceeds a threshold, the transmission interval is reduced to a shorter period; when below the threshold, the interval is extended to a longer period. This parameter change strategy enables the system to maintain high reliability during critical situations while avoiding unnecessary complexity during stable conditions.
2Measurement precision
If the transmission frequency is increased to improve location information accuracy during disasters, then the measurement precision improves, but the energy consumption and network load increase
Solution Approach 1:
The patent dynamically changes the transmission interval parameter based on danger level assessments. During high-danger periods, the interval is shortened to improve location accuracy; during low-danger periods, the interval is extended to reduce energy consumption. This conditional parameter adjustment resolves the contradiction by optimizing the balance between accuracy and energy usage according to actual disaster conditions.
Solution Approach 2:
The patent implements periodic transmission with variable periods. Instead of continuous or fixed-period transmission, the system uses periodic transmission where the period length adapts to danger levels. This approach ensures sufficient location updates during critical moments while allowing energy-saving intervals during safe periods, thus resolving the energy-accuracy trade-off.
3Productivity
If the transmission frequency is increased to track wireless device users more accurately during disasters, then the productivity of rescue operations improves, but the loss of time for processing and transmitting data increases
Solution Approach 1:
The patent adjusts the transmission interval parameter dynamically based on danger levels and device locations. When devices are in high-risk zones, the interval is shortened to improve tracking productivity for rescue operations. When devices are in safe zones, the interval is extended to reduce overall data transmission time and network load. This selective parameter adjustment optimizes the productivity-time trade-off.
Solution Approach 2:
The patent applies different transmission frequencies to different spatial locations based on danger levels. Devices in high-danger areas experience more frequent transmissions to enhance rescue tracking, while devices in low-danger areas use less frequent transmissions. This localized quality adjustment resolves the contradiction by concentrating resources where they are most needed for rescue productivity while minimizing overall time loss.
