Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control beam maintains continuous coverage to support user access, then the reliability of user access is improved, but the power consumption of the satellite increases
Solution Approach 1:
The patent segments the beam coverage into control beam coverage and service beam coverage. The control beam provides basic coverage with reduced power consumption, while service beams provide additional coverage in specific areas. This segmentation allows the system to maintain user access reliability through the control beam while reducing overall power consumption by deactivating or reducing power to service beams when not needed.
Solution Approach 2:
The patent implements periodic beam switching where service beams are activated only when needed for specific users or time periods. The terminal periodically monitors for service beam availability and switches between control beam and service beam based on current needs. This periodic activation of service beams maintains user access reliability when required while significantly reducing power consumption during periods when service beams are deactivated.
2Adaptability or versatility
If the control beam coverage area is enlarged to support more users, then the adaptability of the system is improved, but the power consumption of the satellite increases
Solution Approach 1:
The patent divides the large control beam coverage into multiple smaller service beam coverage areas. The control beam maintains broad coverage for basic adaptability, while individual service beams can be selectively activated to provide enhanced coverage in specific regions. This allows the system to maintain adaptability through the control beam's wide coverage while reducing power consumption by activating only the necessary service beams rather than maintaining full power across the entire coverage area.
3Use of energy by moving object
If the service beam coverage area is reduced to concentrate power, then the power consumption is reduced, but the reliability of data communication service deteriorates
Solution Approach 1:
The patent implements dynamic beam switching where the service beam can be activated or deactivated based on real-time user needs and traffic conditions. When a service beam is activated, it provides concentrated power for reliable data communication in its specific coverage area. When deactivated, the terminal falls back to the control beam for basic service. This dynamic adjustment allows the system to reduce power consumption by keeping service beams inactive most of the time while maintaining data communication reliability when service beams are activated through proper handover mechanisms.
Solution Approach 2:
The control beam serves as an intermediary that provides continuous basic coverage and serves as a fallback when service beams are deactivated. The terminal uses the control beam for initial access and maintains connectivity even when service beams are not available. This intermediary control beam ensures that data communication service reliability is maintained during transitions between service beam states, allowing the system to reduce power consumption without completely sacrificing service reliability.
4Use of energy by moving object
If the service beam is deactivated to reduce power consumption, then the satellite power consumption is reduced, but the terminal cannot receive data communication services timely
Solution Approach 1:
The patent implements preliminary actions by having the terminal continuously monitor for service beam availability and maintain readiness to switch to service beams when activated. The network side device can pre-activate service beams based on predicted user needs or traffic patterns. This preliminary preparation ensures that when service beams are activated, terminals can quickly switch and receive data communication services without significant delay, thus reducing power consumption while minimizing service response time loss.
Solution Approach 2:
The patent implements feedback mechanisms where the terminal reports its service needs and received signal quality to the network side device. Based on this feedback, the network can make informed decisions about when to activate service beams. The terminal also provides feedback about service quality when using control beams, allowing the network to optimize the timing and duration of service beam activation. This feedback loop ensures that service beams are activated only when truly needed, reducing power consumption while maintaining timely service response through intelligent scheduling.
