Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If an RFID module is integrated with a smartcard connector to save configuration space, then the device becomes more compact, but the antenna induction performance deteriorates due to different dimensions and specifications
Solution Approach 1:
A wave absorption material is introduced as an intermediary element between the RFID module and the smartcard connector base. This mediator absorbs electromagnetic waves and prevents interference between the RFID antenna and the smartcard reading area, allowing both functions to coexist without compromising performance. The wave absorption material acts as a buffer that resolves the conflict between compact integration and antenna induction performance.
Solution Approach 2:
The patent positions the RFID module in a different spatial dimension relative to the smartcard connector base, specifically placing it on the upper surface at a predetermined distance. This dimensional separation allows the RFID antenna to maintain its induction performance while the smartcard connector functions independently below, solving the integration problem without compromising either function.
2Volume of moving object
If the RFID module is positioned close to the smartcard connector base to save space, then the device is more compact, but the antenna induction performance is affected
Solution Approach 1:
The wave absorption material serves as a mediator that allows the RFID module to be positioned close to the smartcard connector base while maintaining antenna induction performance. The material absorbs electromagnetic interference and prevents the proximity from degrading performance, enabling compact integration without sacrificing reliability.
Solution Approach 2:
The patent changes the electromagnetic parameter environment by introducing wave absorption material that modifies the electromagnetic field distribution. This parameter change allows the system to maintain optimal antenna induction performance even when the RFID module is positioned close to the smartcard connector, resolving the contradiction between compactness and performance.
