Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal uses multiple SIM cards to communicate simultaneously, then the terminal can maintain multiple communication connections, but communication conflicts occur between SIM cards leading to impaired communication effects
Solution Approach 1:
The patent introduces base station capability information as an intermediary element that mediates between multiple SIM cards and the network. The terminal queries and compares capability information from different base stations to select the most suitable one for handling multi-SIM communication conflicts, thereby resolving communication effects without sacrificing multi-SIM capability
Solution Approach 2:
The patent implements a feedback mechanism where the terminal actively queries base station capability information and uses this feedback to make informed decisions about network selection and communication handling. This feedback loop enables the terminal to adapt its communication strategy based on real-time capability information, resolving conflicts while maintaining versatility
2Reliability
If the terminal continuously monitors network information to resolve multi-card problems, then communication conflicts can be addressed, but energy consumption increases
Solution Approach 1:
The patent applies preliminary action by having base stations broadcast their capability information in advance before the terminal needs to resolve multi-card conflicts. This allows the terminal to cache and store the capability information, so when conflicts arise, the terminal can make quick decisions without continuously monitoring or querying the network, thus reducing energy consumption while maintaining reliable conflict resolution
Solution Approach 2:
The terminal performs self-service by autonomously querying, comparing, and selecting base stations based on published capability information. This self-service approach eliminates the need for continuous network monitoring and manual intervention, allowing the terminal to independently resolve multi-card problems with minimal energy expenditure
3Adaptability or versatility
If the terminal queries capability information from multiple base stations, then the most suitable base station can be selected, but the complexity of network selection increases
Solution Approach 1:
The patent segments the complex network selection process into distinct, manageable steps: the terminal first queries capability information from candidate base stations, then compares the segmented capability parameters (such as supported card types, conflict resolution mechanisms), and finally selects the most suitable base station. This segmentation simplifies the overall selection process by breaking down the complexity into sequential, straightforward comparisons
