Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices with limited baseband bandwidth receive information on multiple sub-bands, then data reliability is improved through redundancy, but device complexity increases due to multiple processing modes
Solution Approach 1:
The patent segments the information processing into different sub-bands and provides multiple processing modes (first mode with filtering and combining, second mode with separate baseband conversion, third mode with simultaneous conversion). This segmentation allows devices with limited baseband bandwidth to handle multiple sub-bands through structured division of processing tasks, improving data reliability while managing complexity through mode selection.
Solution Approach 2:
The patent implements dynamic mode selection where the network entity can switch between different processing modes based on device capabilities and channel conditions. The first mode uses filtering and analog combining for reliability, the second mode uses separate baseband conversion for simplicity, and the third mode uses simultaneous conversion for efficiency. This dynamic adaptation resolves the contradiction by choosing the appropriate complexity level needed for each scenario.
2Use of energy by moving object
If information is repeated on different sub-bands, then energy harvesting capability is improved, but loss of time increases due to multiple processing timelines
Solution Approach 1:
The patent performs preliminary actions by receiving information instances on multiple sub-bands before processing. The network entity can prepare multiple sub-band information in advance and process them according to different timelines, allowing energy harvesting from repeated information while managing processing time through staged execution of different modes.
Solution Approach 2:
The patent employs periodic processing where information is received repeatedly on different sub-bands and processed in periodic cycles. The network entity can process different portions of information at different timelines, enabling continuous energy harvesting from repeated transmissions while managing overall processing time through efficient periodic cycles.
3Productivity
If multiple instances of information are processed simultaneously, then productivity is improved, but device complexity increases due to multiple conversion and sampling operations
Solution Approach 1:
The patent merges multiple information instances from different sub-bands and processes them simultaneously in the third mode through simultaneous baseband conversion. This combining approach improves productivity by handling multiple information streams concurrently while managing complexity through unified processing architecture that handles all sub-bands through a single coordinated operation.
Solution Approach 2:
The patent implements a universal processing framework that can handle multiple information instances on different sub-bands through a single multi-functional processing system. The network entity uses universal conversion and sampling operations that work across all sub-bands, improving processing efficiency while avoiding the need for separate dedicated processing paths for each sub-band.
