Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the smart identifying apparatus continuously communicates with IOT gateways to determine user location, then the location detection accuracy is improved, but the battery consumption increases
Solution Approach 1:
The apparatus uses motion detection circuits to trigger communication only when user motion is detected, rather than continuously communicating. This periodic action based on motion events significantly reduces battery consumption while maintaining location detection accuracy when needed.
Solution Approach 2:
A motion detection circuit acts as an intermediary between the user's physical movement and the communication circuit. The motion detection circuit triggers communication events, serving as a mediator that reduces unnecessary direct communication between the smart identifying apparatus and IOT gateways.
2Adaptability or versatility
If the smart identifying apparatus uses motion detection and communication circuits to determine user location, then the functionality is improved, but the device complexity increases
Solution Approach 1:
The patent integrates the motion detection circuit, processing circuit, and communication circuit into a single unified system. By merging these functions into one integrated device, the overall system complexity is reduced compared to having separate devices for motion detection and location communication.
Solution Approach 2:
The smart identifying apparatus serves multiple functions: it detects user motion, determines location based on motion patterns, communicates with IOT gateways, and can be integrated into various devices like mobile phones or vehicles. This multi-functionality reduces the need for separate specialized devices.
3Ease of operation
If the smart identifying apparatus is made portable and integratable into various devices, then the ease of operation is improved, but the battery capacity is limited
Solution Approach 1:
The apparatus employs event-driven communication triggered by motion detection, rather than continuous operation. This periodic activation based on user motion significantly extends battery life while maintaining portability and ease of operation across different devices.
Solution Approach 2:
The system dynamically changes its operational parameters based on detected motion events. When motion is detected, the apparatus transitions from a low-power state to an active communication state, optimizing battery usage while maintaining portability.
