Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wireless communication is used to couple sensors and actuators without cables, then installation cost is reduced and operational constraints are eliminated, but signal quality degrades due to polarized wave shifts caused by electromagnetic wave reflection from surrounding devices
Solution Approach 1:
The patent applies dynamics by making the transmission polarized wave rotatable rather than fixed. The transmission polarized wave rotation unit rotates the polarized wave in the transmission direction to align with the reception polarized wave direction, which changes dynamically based on the wireless environment. This dynamic adjustment resolves the contradiction by maintaining signal quality (reliability) while preserving the wireless installation advantage.
Solution Approach 2:
The patent changes the parameter of polarized wave orientation by rotating the transmission polarized wave. The rotation angle is adjusted according to the detected reception polarized wave direction, transforming the fixed parameter into a variable one. This parameter change enables the system to adapt to environmental variations and maintain reliable communication despite electromagnetic wave reflections.
2Reliability
If transmission power is increased to overcome signal degradation, then communication quality improves, but power consumption of the wireless circuit exceeds limitations
Solution Approach 1:
Instead of changing transmission power, the patent changes the parameter of polarized wave orientation. By rotating the transmission polarized wave to match the reception direction, the system improves communication quality through optimal alignment rather than increased power, thus avoiding additional energy consumption.
Solution Approach 2:
The patent implements feedback by having the transmission device detect the reception polarized wave direction and adjust the transmission polarized wave rotation accordingly. This feedback mechanism enables the system to maintain communication quality through adaptive alignment rather than continuous high power transmission, reducing overall energy consumption.
3Reliability
If error correction circuits are switched and used to correct information errors, then error correction capability increases, but the underlying signal quality degradation due to polarized wave misalignment cannot be recovered
Solution Approach 1:
The patent applies preliminary action by rotating the transmission polarized wave to align with the reception direction before transmission occurs. This preventive measure ensures that the signal is transmitted in the optimal polarized wave direction, preventing signal quality degradation and information loss before error correction is needed.
Solution Approach 2:
The patent converts the harmful effect of fixed polarized wave transmission into a benefit by implementing rotatable transmission polarized waves. The system uses the detected reception polarized wave direction to rotate the transmission wave, transforming the potential harm of misalignment into the benefit of optimal alignment, thereby preventing signal quality degradation at its source.
