Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing security devices are used for tracking assets, then location tracking is provided, but network signal loss causes tracking failure
Solution Approach 1:
The patent introduces Bluetooth Low Energy (BLE) technology as an intermediary communication layer between the security device and the tracking system. BLE enables local wireless communication that can operate independently of traditional cellular network signals, allowing the device to maintain tracking functionality even when network signals are lost. The BLE module acts as a mediator that bridges the gap between the secured asset and the monitoring system in areas with poor network coverage.
2Ease of operation
If authorized persons are given access to unlock secured assets, then authorized access is enabled, but lapses in procedures lead to security breaches
Solution Approach 1:
The patent implements automated feedback mechanisms through the tracking system that monitor and record access events, device status changes, and location information. The system provides real-time feedback to authorized personnel and system administrators, enabling immediate detection of unauthorized access attempts or procedural lapses. This continuous feedback loop enhances security by ensuring that any deviation from authorized procedures is promptly identified and addressed.
3Reliability
If multiple communication modules are added to ensure tracking reliability, then network coverage is improved, but device complexity increases
Solution Approach 1:
The patent leverages the universality of Bluetooth Low Energy technology, which serves multiple functions within a single integrated module. The BLE module not only provides alternative communication capability for tracking but also enables local data transmission, device identification, and wireless pairing capabilities. This multi-functional approach allows the system to maintain communication reliability without proportionally increasing device complexity, as one module performs several critical functions simultaneously.
