Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are incorporated to monitor functional performance of IoT devices, then measurement precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies multi-functionality by enabling a single UWB sensor to perform multiple monitoring tasks including anomaly detection in IoT devices, quality monitoring of organic and inorganic items, and non-contact measurement. The sensor system can detect various parameters such as material properties, motion, and functional performance using one sensor type, eliminating the need for multiple specialized sensors while maintaining comprehensive monitoring capabilities.
Solution Approach 2:
The patent utilizes parameter changes by monitoring variations in material property parameters and motion parameters through UWB signal analysis. The system detects anomalies by identifying changes in these parameters over time, allowing a single sensor to track multiple aspects of object performance and quality without requiring multiple sensor types.
2Measurement precision
If a camera is used to monitor functional performance of IoT devices, then measurement precision is improved, but user privacy is compromised
Solution Approach 1:
The patent replaces the optical camera system with a UWB-based sensing system. Instead of using visual imaging that captures user identity and privacy-sensitive information, the UWB sensor performs non-contact measurement of functional performance and anomaly detection through electromagnetic wave interaction with objects, thereby maintaining monitoring precision while eliminating privacy concerns.
Solution Approach 2:
The patent introduces UWB electromagnetic waves as an intermediary medium for monitoring. Rather than directly observing objects with a camera, the system uses UWB signals as an intermediate to interact with objects and extract performance information, allowing functional monitoring without direct visual capture of users or sensitive areas.
3Device complexity
If a single sensor is used to monitor multiple types of objects, then device complexity is reduced, but adaptability to different objects may be compromised
Solution Approach 1:
The patent demonstrates universality by showing how a single UWB sensor can monitor diverse objects including IoT devices, organic items (food, crops), and inorganic items (chemical compounds). The sensor system adapts to different object types by analyzing various physical parameters reflected in UWB signals, maintaining versatility while using a single sensor platform.
Solution Approach 2:
The patent applies parameter changes by monitoring different physical properties of various materials through UWB signal analysis. The system can detect material property parameters, motion parameters, and quality indicators by analyzing how UWB waves interact with different materials, enabling a single sensor to adapt to monitoring various object types through parameter-based differentiation.
