Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If wideband scanning is performed by receiving signals from multiple channels, then device search speed is improved, but power consumption increases
Solution Approach 1:
The patent divides the wideband scanning process into multiple discrete channel reception operations. Instead of continuously scanning all channels, the processor receives signals from multiple channels at specific time intervals, segmenting the scanning task into manageable discrete steps that reduce overall power consumption while maintaining search speed
Solution Approach 2:
The patent implements periodic channel scanning where the processor receives signals from multiple channels at designated time intervals rather than continuously. This periodic action allows the device to balance between maintaining adequate search speed and reducing power consumption by being active only when needed
2Loss of time
If signals from multiple channels are received concurrently, then device search time is reduced, but processing complexity increases
Solution Approach 1:
The patent segments the signal processing task by dividing it into channel-specific reception operations. Each channel's signal is processed independently through dedicated processing steps, which simplifies the overall complexity compared to handling all channels as a single complex stream, while still achieving reduced search time through parallel channel monitoring
Solution Approach 2:
The processor is designed with multi-functional capability to handle signal reception and processing across multiple channels using a unified framework. This universal processing approach reduces overall system complexity by using the same processing logic across different channels rather than requiring separate dedicated processing paths for each channel
