Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless communication device uses traditional power sources, then it can maintain continuous operation and data transfer, but it lacks portability and requires physical connection to host devices
Solution Approach 1:
The patent replaces traditional mechanical power connection (physical cables and power sources) with wireless electromagnetic energy transmission. The wireless communication device receives power wirelessly through electromagnetic fields, eliminating the need for physical connections while maintaining continuous operation capability.
Solution Approach 2:
The device integrates multiple functions into a single portable unit: it serves as both a communication device and a power-receiving device. The wireless power reception capability allows the same device to operate independently without host device power supply, enhancing portability while maintaining reliability.
2Adaptability or versatility
If a wireless communication device integrates both SD and NFC interfaces, then it enables multi-device communication and data transfer, but it increases device complexity
Solution Approach 1:
The patent divides the communication functionality into distinct segments: SD interface for high-speed data transfer and NFC interface for近距离 communication and power reception. Each interface operates independently with its own protocol stack, allowing complex multi-device communication while managing complexity through modular design.
Solution Approach 2:
The wireless communication device acts as an intermediary between different types of devices. It can receive data from SD cards, transfer via NFC, and communicate with various host devices using appropriate protocols, thereby enabling multi-device communication without requiring direct integration between all device types.
3Ease of operation
If a wireless communication device operates without host power supply, then it achieves greater portability and independence, but it faces challenges in power management and energy sustainability
Solution Approach 1:
The device performs self-powering by receiving wireless electromagnetic energy directly. It manages its own power consumption by optimizing transmission/reception cycles, buffering data operations, and controlling NFC/SD interface activities based on available energy, thereby achieving independence while managing power sustainability.
Solution Approach 2:
The wireless communication device operates in periodic cycles: receiving electromagnetic energy bursts, buffering data, performing communication operations, and repeating. This periodic operation pattern allows the device to accumulate sufficient energy for each operation cycle, managing power consumption sustainably while maintaining independence.
