Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical inspection is used to verify item presence, then accuracy of detection is improved, but time consumption and user convenience deteriorate
Solution Approach 1:
The patent replaces manual physical inspection with an automated sensor-based detection system. Sensors detect wireless signals (RFID, Bluetooth, Wi-Fi) emitted by tracked items, automatically determining their presence without requiring user intervention. This substitution of mechanical inspection with electronic detection resolves the contradiction by providing both high accuracy and time efficiency.
Solution Approach 2:
The system enables self-service detection where the wearable item autonomously monitors and reports the presence of important items within it. The sensors and control circuits automatically perform detection and communicate status to the user, eliminating the need for manual verification while maintaining continuous monitoring capability.
2Loss of information
If a tracking system is added to wearable items, then item presence monitoring capability is improved, but device complexity increases
Solution Approach 1:
The patent employs multi-functional sensors that can detect various wireless signals (RFID, Bluetooth, Wi-Fi) using a single detection platform. The control circuit is designed to handle multiple signal types and communicate through universal interfaces. This multi-functionality reduces overall system complexity compared to implementing separate dedicated systems for each tracking method.
Solution Approach 2:
The substrate is designed as a flexible, thin structure that can be easily integrated into various wearable items without adding significant bulk or rigidity. This flexible substrate carries the sensors and circuits while adapting to different item shapes and sizes, simplifying the integration process and reducing structural complexity.
3Reliability
If sensors and control circuits are integrated into the wearable item, then detection capability is improved, but manufacturing complexity increases
Solution Approach 1:
The system is divided into modular components: the flexible substrate with integrated sensors, control circuits, and power management units. Each module can be manufactured separately using standardized processes and then assembled into the final wearable item. This segmentation improves reliability through specialized component manufacturing while easing assembly through modular integration.
Solution Approach 2:
Multiple functional elements (sensors, control circuits, antenna elements, and substrate) are combined into a single integrated flexible unit. This merging reduces the number of separate assembly steps and components, thereby simplifying the manufacturing process while maintaining reliable detection functionality through integrated design.
