Engineering Contradiction Analysis
1Adaptability or versatility
If a deformable substrate is used to enable shape changes in the electronic device, then the adaptability of the device is improved, but the electrical characteristics of RF signals deteriorate due to substrate deformation
Solution Approach 1:
The system measures the electrical characteristics of RF signals after they pass through the deformable substrate and feeds this information back to the processor. The processor then adjusts transmission parameters based on this feedback to compensate for the effects of substrate deformation, maintaining reliable communication despite shape changes.
Solution Approach 2:
The system dynamically changes transmission parameters such as power and frequency based on the measured electrical characteristics of the deformable substrate. By adjusting these parameters in response to substrate deformation, the system maintains optimal RF signal performance across different device shapes.
2Reliability
If transmission power is increased to compensate for signal loss, then communication performance is maintained, but energy consumption increases
Solution Approach 1:
Instead of always increasing transmission power, the system dynamically adjusts multiple parameters including power and frequency based on the measured electrical characteristics of the substrate. This selective parameter adjustment maintains communication performance while minimizing unnecessary energy consumption.
Solution Approach 2:
The system uses feedback from electrical characteristic measurements to make intelligent decisions about when and how to adjust transmission parameters. This feedback mechanism ensures that energy is only increased when necessary to maintain performance, rather than continuously consuming maximum power.
3Adaptability or versatility
If the substrate is made more flexible to enable greater deformation, then the adaptability of the device is improved, but the signal loss increases
Solution Approach 1:
The system continuously monitors the electrical characteristics of RF signals passing through the flexible substrate and uses this feedback to compensate for signal loss. By measuring the actual signal degradation and adjusting transmission parameters accordingly, the system maintains performance even as substrate flexibility increases.
Solution Approach 2:
The system dynamically adjusts transmission parameters such as power and frequency in response to measured substrate characteristics. This allows the system to optimize signal transmission through highly flexible substrates that would otherwise cause significant signal loss, enabling greater adaptability without sacrificing communication reliability.
