Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna is formed on the surface of the microcircuit board, then the antenna can be integrated into the device, but the antenna size exceeds the available surface area and electromagnetic interference from the device body and battery degrades signal quality
Solution Approach 1:
The device is divided into two separate components: a microcircuit board containing the microcircuit and an external support containing the antenna. This segmentation allows the antenna to be positioned independently from the microcircuit board, enabling it to be located in optimal positions for signal quality while maintaining device integration.
Solution Approach 2:
A flexible printed circuit board acts as an intermediary element connecting the microcircuit board to the external support containing the antenna. This intermediary allows for flexible positioning and electrical connection while isolating the antenna from electromagnetic interference generated by the device body and battery.
2Area of stationary object
If a finer resolution is used to reduce antenna size, then the antenna can fit within device dimensions, but manufacturing costs increase
Solution Approach 1:
The antenna is moved from a two-dimensional surface configuration on the microcircuit board to a three-dimensional external support structure. This dimensional change allows the antenna to utilize available space more efficiently without requiring finer trace resolution, thereby maintaining standard manufacturing processes and costs.
3Reliability
If the SIM card is separated from the microcircuit board to avoid electromagnetic interference, then signal quality improves, but the assembly becomes too thick and inflexible to install in devices not designed for it
Solution Approach 1:
The connection between the microcircuit board and the external support is made flexible through the use of a flexible printed circuit board. This dynamic connection allows the antenna assembly to adapt to different device configurations and installation spaces, improving compatibility while maintaining the separation needed for signal quality.
Solution Approach 2:
The microcircuit board is nested within the external support structure, with the flexible printed circuit board serving as the connecting layer. This nested configuration allows the entire assembly to maintain a compact profile suitable for installation in various device types while keeping the antenna positioned for optimal signal quality.
