Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless communication interfaces share the same transmission medium, then device functionality and communication versatility are improved, but interference and cross-talk between interfaces worsen
Solution Approach 1:
The patent segments the wireless transmission medium usage by dividing time into distinct frames, where different wireless interfaces (e.g., LTE and WLAN) are allocated specific time slots. This temporal segmentation allows multiple interfaces to share the same medium without simultaneous operation, thereby eliminating interference while maintaining communication versatility.
Solution Approach 2:
The patent implements periodic time-division multiplexing where wireless interfaces operate in periodic cycles. Each interface is activated during its designated time frame and remains inactive during other interfaces' active periods. This periodic scheduling ensures that transmission and reception operations do not overlap, preventing cross-talk while enabling multi-interface functionality.
2Productivity
If wireless interfaces operate simultaneously on the same frequency band, then communication efficiency is improved, but data loss due to interference worsens
Solution Approach 1:
The patent dynamically controls the activation and deactivation of wireless communication interfaces based on scheduled time frames. The system adapts the operational state of each interface according to pre-defined timing patterns, switching between active and inactive states to avoid simultaneous transmission and reception. This dynamic control ensures reliable data transmission by eliminating interference while maintaining high communication efficiency through optimized resource utilization.
3Reliability
If reception is continuously monitored to detect data, then data reliability is improved, but energy consumption worsens
Solution Approach 1:
The patent employs periodic reception monitoring aligned with the time-division multiplexing schedule. Instead of continuous monitoring, the reception circuit is activated only during designated time frames when data transmission is expected according to the schedule. This periodic approach maintains data reliability by detecting transmissions at appropriate intervals while significantly reducing energy consumption by keeping the reception circuit inactive during other time slots.
Solution Approach 2:
The system uses the control region information, which is periodically transmitted and contains scheduling data, to autonomously determine when reception should be active. The periodic reception is self-regulated based on the scheduled transmission patterns indicated in control regions, eliminating the need for continuous monitoring while ensuring data is not missed.
