Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic stripe readers and capacitive touch screens are used for data communication, then data transmission between devices is enabled, but errors and security vulnerabilities occur during transmission
Solution Approach 1:
The patent implements feedback mechanisms where the receiving device sends acknowledgment signals back to the transmitting device. If data is not received correctly or is not acknowledged within a specified time frame, the transmitting device retransmits the data, ensuring reliable communication and preventing data loss during magnetic stripe reading and capacitive touch operations.
Solution Approach 2:
The patent replaces traditional mechanical contact-based magnetic stripe reading with optical communication using light sensors and LEDs. This substitution eliminates wear and tear associated with mechanical components and reduces transmission errors by using non-contact optical fields for data exchange between devices.
2Adaptability or versatility
If proprietary communication protocols are used, then device-specific communication requirements are met, but compatibility with other devices is limited
Solution Approach 1:
The patent implements a universal communication protocol that can operate across multiple device types including smartphones, wearables, and IoT devices. The system uses standardized light sensor and LED interfaces that work across different platforms, eliminating the need for device-specific proprietary protocols while maintaining full communication functionality through a single unified approach.
Solution Approach 2:
The patent employs parameter changes in light intensity, frequency, and pulse duration to encode different data types and communication modes. By varying these optical parameters, the system can handle different communication requirements (reading magnetic stripe data, detecting capacitive touch, sending notifications) without requiring different protocols, thus reducing overall system complexity while maintaining versatility.
3Ease of operation
If light sensors and LEDs are used for communication, then wireless data transmission is achieved, but interference from ambient light and synchronization issues occur
Solution Approach 1:
The patent uses periodic pulsed light signals with specific frequencies for data transmission. The system emits light in synchronized pulses rather than continuous illumination, allowing the receiving light sensor to distinguish transmitted signals from ambient light through frequency discrimination. This periodic action enables reliable wireless communication while filtering out continuous ambient light interference.
Solution Approach 2:
The patent implements dynamic adjustment of light emission intensity and timing based on ambient light conditions. The system continuously monitors ambient light levels and adapts its transmission parameters accordingly, increasing pulse intensity in bright environments and adjusting timing to avoid interference from natural light cycles, thereby maintaining ease of operation across varying environmental conditions.
