Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the processor of the radio frequency chip implements multiple functions (encoding, decoding, data reception, sending, analog-to-digital conversion, digital-to-analog conversion), then the device integrates more functions in one component, but the processing load of the processor increases, leading to poor encoding or decoding processing effect
Solution Approach 1:
The patent divides the processing functions into two separate processors: the first processor in the radio frequency chip handles control functions (data reception, sending, analog-to-digital conversion, digital-to-analog conversion), while the second processor in the computing power chip is dedicated to encoding and decoding operations. This segmentation allows each processor to specialize in specific tasks, improving both the processing effect and reducing the load on any single processor.
2Device complexity
If the processor of the radio frequency chip handles all processing tasks, then the device structure is simplified, but the processing load increases, making it difficult to improve processing effect
Solution Approach 1:
The patent segments processing tasks between two processors across separate chips. The first processor handles control and communication tasks, while the second processor in the computing power chip handles computationally intensive encoding and decoding. This segmentation improves productivity and processing effect while maintaining a relatively simple device structure through modular chip design.
Solution Approach 2:
The patent introduces a computing power chip as an intermediary component between the radio frequency chip and the audio processing pipeline. This intermediary processor specializes in encoding and decoding operations, acting as a mediator that offloads computational tasks from the main processor, thereby improving overall processing effectiveness without significantly complicating the device architecture.
