Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a GPS tracking system is integrated into the smart card, then real-time location tracking capability is improved, but the card's form factor and thickness are disrupted
Solution Approach 1:
The patent embeds the GPS tracking system within the existing smart card structure, nesting the tracking functionality inside the card's housing rather than adding external components. This allows the GPS system to be integrated without significantly increasing the card's overall dimensions, resolving the contradiction between fraud prevention capability and card thickness.
Solution Approach 2:
The patent utilizes thin-film technology and flexible circuit boards to accommodate the GPS components within the constrained thickness of the smart card. By employing thin-film structures, the system achieves real-time tracking functionality while maintaining the card's conventional form factor.
2Measurement precision
If a nano GPS chip is added to the smart card, then location tracking precision is improved, but the device complexity increases
Solution Approach 1:
The patent integrates the nano GPS chip with the existing smart card microprocessor and communication interfaces, allowing the GPS functionality to share computational and communication resources with other card functions. This multi-functionality approach reduces overall device complexity while maintaining high location tracking precision.
Solution Approach 2:
The patent combines the GPS tracking system with the smart card's existing electronic components, merging the location determination function with the card's processor and memory. This consolidation reduces the number of separate components and simplifies the overall device structure while achieving precise location tracking.
3Reliability
If real-time location monitoring is implemented, then transaction security is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic location updates rather than continuous monitoring, where the GPS system determines location at intervals based on transaction needs. This periodic operation significantly reduces power consumption while maintaining adequate transaction security by verifying card-user proximity at relevant moments.
Solution Approach 2:
The patent employs the smart card's existing communication interface and the user's mobile device to handle location data transmission and processing, rather than requiring the card to continuously power high-energy transmission components. The system leverages the mobile device's resources for communication, reducing the card's own power consumption while maintaining security.

AI summary
A method for use with a smart card is provided. The smart card may include a communication interface, a housing, a microprocessor embedded in the housing, a battery for powering the communication interface and the microprocessor, and a nano GPS chip, located within the housing and in electronic communication with the communication interface and the microprocessor. The thickness of the smart card is preferably no greater than 0.8 millimeters (“mm”) and has surface area not greater than 86 mm×54 mm. The method may include determining the location of the smart card in response to a request for a smart card transaction authorization and determining the location of a mobile device associated with a specified user of the smart card. Based on the location of the smart card and the location of the mobile device, the smart card may calculate a location delta between the smart card and the mobile device. If the location delta is greater than or equal to a threshold distance, the smart card may deny the request for smart card transaction authorization.
