Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If NFC techniques are used for mobile payments, then wireless payment convenience is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The patent replaces the wireless electromagnetic field-based NFC communication system with a mechanical vibration-based communication system. The mobile device generates tactile vibrations that are transmitted through physical contact with the merchant terminal, substituting the original wireless electromagnetic mechanism with a mechanical vibration mechanism. This substitution fundamentally changes the communication medium from air-based electromagnetic waves to solid-contact mechanical vibrations, thereby eliminating the security vulnerabilities of wireless NFC while maintaining contactless convenience.
Solution Approach 2:
The patent introduces a new intermediary medium - mechanical vibrations - between the mobile device and merchant terminal. Instead of direct wireless electromagnetic communication, the system uses vibrations as an intermediate carrier to transmit payment data. The vibrations serve as a mediator that converts digital payment information into physical tactile signals, which are then converted back into readable data at the terminal, adding a layer of physical security to the transaction process.
2Reliability
If vibration-based communication is used, then security is improved, but device complexity increases
Solution Approach 1:
The patent makes the haptic actuator serve multiple functions: it provides tactile feedback to the user during normal operation and simultaneously transmits encoded payment data through vibration patterns during transactions. By making the vibration motor multi-functional, the system avoids adding dedicated complex transmission hardware, as the existing haptic component is repurposed for data communication in addition to its primary user feedback role.
Solution Approach 2:
The patent encodes payment data by varying parameters of the vibration signals, such as frequency, amplitude, and duration patterns. Instead of adding complex communication protocols or additional hardware, the system modifies the temporal and intensity parameters of the vibrations to represent different data values. This parameter-based encoding allows existing haptic actuators to convey complex payment information through simple variations in vibration characteristics.
