Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth tags are used for asset tracking, then wireless communication and tracking capability are provided, but the setup process becomes onerous and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-configuring the Bluetooth tag with default settings and identifiers during manufacturing. The tag is pre-programmed with its unique ID and communication protocols, eliminating the need for manual setup at the point of use. This allows the tag to be immediately activated and paired with mobile devices without requiring user intervention in the configuration process.
2Adaptability or versatility
If Bluetooth tags are used for asset tracking, then wireless communication is enabled, but the number of tags that can be paired with one mobile device is limited
Solution Approach 1:
The patent applies dynamics by implementing a dynamic pairing mechanism that allows mobile devices to connect with multiple Bluetooth tags simultaneously. The system enables a mobile device to scan for and pair with multiple tags without being constrained by traditional Bluetooth pairing limits. This dynamic approach allows the device to maintain connections with numerous tags through sequential or parallel pairing operations, significantly increasing adaptability.
3Duration of action of moving object
If Bluetooth tags are used for asset tracking, then tracking functionality is provided, but battery life is depleted quickly
Solution Approach 1:
The patent applies periodic action by implementing intermittent broadcasting of location data rather than continuous transmission. The Bluetooth tag transmits its location information at predetermined time intervals (e.g., every few seconds or minutes) rather than continuously, significantly reducing energy consumption. This periodic broadcasting maintains tracking functionality while extending battery life, allowing the tag to operate for extended periods without requiring frequent battery replacements.
4Reliability
If Bluetooth tags are used for asset tracking, then communication capability is provided, but the tags become vulnerable to hacking
Solution Approach 1:
The patent applies preliminary anti-action by implementing security measures during the tag design and manufacturing phase to prevent hacking attempts before they can occur. The Bluetooth tags are equipped with built-in security features such as encryption protocols, unique identifiers, and authentication mechanisms that are pre-configured to resist unauthorized access. These preliminary security measures create a protective barrier that prevents potential hackers from exploiting the tags, even when they are transmitted wirelessly.
5Extent of automation
If traditional asset tags are used, then basic tracking is possible, but automated reading and two-way communication are not available
Solution Approach 1:
The patent applies universality by designing the Bluetooth tag to perform multiple functions simultaneously: it provides location tracking, wireless communication, periodic broadcasting, and security features all within a single integrated device. The tag serves both as a passive tracking identifier and an active communication device, enabling automated reading by mobile devices without requiring separate systems. This multi-functionality reduces the need for additional complex infrastructure while achieving automated tracking and communication capabilities.

AI summary
An asset tag adapted to be mounted to an asset. The asset tag comprises a first component encoded with a first ID unique to the asset tag, the first component having a first wireless interface and transmitting first broadcast signals via said first wireless interface over a first range, the first broadcast signals including the first ID. The asset tag further comprises a user-actuatable button. The asset tag further comprises processing circuitry, coupled to the button and to at least the first wireless interface. The processing circuitry is configured for (i) determining whether a predetermined gesture has been performed by a user using the button and (ii) if the predetermined gesture has been performed, transmitting via the first wireless interface to a wireless access point a restock message, the restock message including the first ID and indicating that restocking is required of assets corresponding to the first ID.
