Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station operates continuously to maintain service availability, then service reliability is improved, but energy consumption increases
Solution Approach 1:
The base station dynamically switches between multiple operational states (first state with full functionality and second state with reduced functionality) based on real-time traffic conditions. This dynamic state adjustment allows the system to maintain service availability when needed while reducing energy consumption during low-traffic periods, resolving the contradiction between reliability and energy usage.
Solution Approach 2:
The patent changes the operational parameters of the base station by transitioning between different states with distinct functional characteristics. In the first state, the base station operates with full parameters for high reliability; in the second state, it operates with reduced parameters to save energy. This parameter change approach enables flexible balancing of reliability and energy consumption.
2Use of energy by moving object
If the base station reduces operational states to save energy, then energy consumption is reduced, but communication performance deteriorates
Solution Approach 1:
The system dynamically transitions between operational states based on traffic conditions. When traffic demands high performance, the base station switches to the first state with full communication capabilities. When traffic is light, it switches to the second state for energy saving. This dynamic approach ensures communication performance is maintained when needed while reducing energy consumption during low-demand periods.
Solution Approach 2:
The base station monitors traffic conditions and uses this feedback to determine when to switch between states. The feedback mechanism ensures that the base station maintains adequate performance for current traffic demands while transitioning to energy-saving modes when performance requirements are low, thus balancing communication performance and energy consumption.
3Use of energy by moving object
If the base station switches states frequently to optimize energy efficiency, then energy consumption is reduced, but system complexity increases
Solution Approach 1:
The operational states are segmented into distinct first and second states with clearly defined functional characteristics. This segmentation simplifies the state switching logic by providing discrete, well-defined states rather than continuous or ambiguous operational modes. The base station can efficiently transition between these segmented states based on traffic conditions, reducing the complexity of state management while optimizing energy efficiency.
