Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the quantity of antennas of a mobile terminal is increased to improve transmission capacity and transmission rate, then the transmission performance is improved, but the power consumption increases
Solution Approach 1:
The patent implements dynamic antenna quantity adjustment by monitoring service types and determining the minimum required antenna count for each service. The system dynamically enables or disables antennas based on current service requirements, transitioning from a static all-antennas-enabled approach to a dynamic adaptive approach that matches antenna usage to actual service needs.
Solution Approach 2:
The patent changes the parameter of antenna quantity from a fixed value to a variable that adapts to different service conditions. By establishing correspondence between service types and required antenna quantities, the system adjusts the operational antenna count parameter according to service requirements, thereby optimizing power consumption while maintaining necessary transmission capacity.
2Reliability
If all antennas are enabled to ensure service execution, then service reliability is improved, but unnecessary energy is wasted when fewer antennas are sufficient
Solution Approach 1:
The patent applies partial action by enabling only the necessary number of antennas required for each specific service rather than all antennas. The system determines the minimum antenna quantity needed for service execution and enables exactly that number, avoiding the excessive action of enabling all antennas when fewer would suffice.
Solution Approach 2:
The mobile terminal autonomously determines its own antenna requirements by analyzing service types and calculating the minimum necessary antenna count. The system performs self-assessment of its operational needs and automatically adjusts antenna configuration without external intervention, enabling it to serve itself optimally.
3Productivity
If multiple antennas are enabled for MIMO technology, then transmission rate is improved, but calculation complexity between terminal and network element increases
Solution Approach 1:
The patent dynamically adjusts the number of enabled antennas based on service requirements and signal conditions, reducing the antenna count from a fixed high number to a variable optimized quantity. This dynamic adjustment lowers calculation complexity for MIMO operations while maintaining transmission rates appropriate to current service needs.
