Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sensor stations are used for earthquake detection, then detection reliability is improved, but device complexity and cost increase, making it difficult to achieve high sensor density in populated areas
Solution Approach 1:
The patent applies universality by enabling existing IoT devices (smartphones, smartwatches, home appliances, vehicles) to serve dual purposes: their original functions plus earthquake detection. These devices already contain sensors (accelerometers, gyroscopes, microphones) that can detect seismic waves, eliminating the need for dedicated sensor stations and reducing device complexity while maintaining detection reliability through widespread deployment
Solution Approach 2:
The patent uses copying by replacing expensive, complex physical sensor stations with replicated, inexpensive IoT devices that already exist in populated areas. Each IoT device acts as a copy of a sensor station, distributed throughout the population, achieving high sensor density without the complexity and cost of traditional stations
2Reliability
If sensor stations are located away from populated areas, then safety of equipment is improved, but warning time is reduced due to increased distance from seismic event origins in populated areas
Solution Approach 1:
The patent applies segmentation by dividing the earthquake detection function across numerous distributed IoT devices rather than relying on a few centralized sensor stations. This segmentation allows devices to be placed throughout populated areas, reducing detection time while the networked architecture and data processing protocols ensure equipment safety through collective redundancy and coordinated operation
Solution Approach 2:
The patent uses intermediary by introducing a centralized processing system that coordinates the distributed IoT devices. This intermediary manages data collection, analysis, and warning dissemination, allowing individual devices to remain simple and safe while the system as a whole achieves both rapid detection and equipment protection through distributed architecture
3Measurement precision
If traditional sensor stations with multiple components are deployed, then detection precision is improved, but ease of installation and maintenance deteriorates
Solution Approach 1:
The patent applies universality by utilizing sensors already present in IoT devices for earthquake detection, eliminating the need for specialized sensor station installation. These devices already contain accelerometers, gyroscopes, and microphones that can detect seismic vibrations with sufficient precision, and their widespread distribution makes them easy to deploy and maintain as part of existing infrastructure
Solution Approach 2:
The patent uses self-service by leveraging the existing operational infrastructure of IoT devices. These devices are already powered, connected to networks, and maintained through their primary functions, so adding earthquake detection capability requires no additional installation or maintenance burden. The devices self-organize into a detection network, automatically participating in seismic monitoring
