Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conductive patterns are formed only on a single surface of the semiconductor package device, then the device structure is simple and manufacturing is easier, but the communication quality deteriorates and transmission errors increase due to misalignment between transmitter and receiver
Solution Approach 1:
The patent extends the conductive patterns from a single surface to multiple surfaces (top, bottom, and lateral surfaces) of the semiconductor package device. This multi-surface configuration enables magnetic field transmission in multiple directions, allowing the NFC device to maintain reliable communication even when transmitter and receiver are misaligned, thereby resolving the contradiction between manufacturing simplicity and communication reliability.
2Reliability
If conductive patterns are formed on multiple surfaces of the semiconductor package device, then communication quality improves and flexibility increases, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The semiconductor package device is designed with conductive patterns on multiple surfaces, enabling it to transmit and receive magnetic fields in multiple directions simultaneously. This multi-functional capability allows the single NFC device to adapt to various alignment scenarios and communication orientations, improving reliability without requiring multiple separate components, thus managing the complexity through functional integration.
3Device complexity
If traditional single-surface NFC design is used, then the device structure is simple, but the design flexibility and placement options are restricted due to parallel alignment requirements
Solution Approach 1:
By adding conductive patterns on lateral surfaces in addition to the top and bottom surfaces, the patent enables magnetic field transmission in multiple spatial dimensions. This allows the NFC device to be placed and oriented in various configurations without requiring strict parallel alignment, significantly improving design flexibility and placement options while maintaining manageable device complexity through integrated circuit board construction.
