Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate circuit units are provided for each frequency band, then wireless communication in multiple frequency bands is supported, but device cost increases
Solution Approach 1:
The signal processing circuits are designed to perform multiple functions by processing wireless signals across different frequency bands (first and second frequency bands). Instead of having separate dedicated circuits for each band, a single set of signal processing circuits handles both bands by generating or demodulating signals in either band, thereby reducing device cost while maintaining multi-band support capability
Solution Approach 2:
The system dynamically switches between different frequency bands based on communication needs. The signal processing circuits can adaptively generate or demodulate signals in the first frequency band or the second frequency band, allowing the device to flexibly respond to different client devices and communication scenarios without requiring static separate circuit units for each band
2Adaptability or versatility
If separate circuit units are provided for each frequency band, then wireless communication in multiple frequency bands is supported, but the number of circuit units increases
Solution Approach 1:
A single set of signal processing circuits performs the function of multiple separate circuits by handling wireless signals in both the first and second frequency bands. The same signal processing circuits can generate or demodulate signals in either band, eliminating the need for separate dedicated circuit units for each frequency band and thereby reducing the total number of circuit units in the device
Solution Approach 2:
The patent merges the functionality of separate frequency band processing circuits into a unified signal processing circuit system. Instead of having independent circuit units for the first frequency band and second frequency band, the signal processing circuits are combined to handle both bands, reducing component count and simplifying the overall device architecture
