Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If independent antenna selection and tuning operations are performed, then each operation can be simplified and implemented separately, but conflicts arise and optimal performance is not achieved
Solution Approach 1:
The patent merges antenna selection and tuning operations into a unified joint decision-making framework. The communication control circuit simultaneously determines both switch state actions and tuner state actions based on runtime measurements and pre-defined databases, eliminating the conflicts that arise from independent operations while achieving optimal antenna performance.
2Adaptability or versatility
If antenna selection causes switch state change, then antenna switching is achieved, but the optimality of tuning result is affected
Solution Approach 1:
The patent performs preliminary actions by establishing pre-defined databases that map switch states to optimal tuner states before runtime operation. During runtime, when a switch state change is detected, the system queries the pre-defined database to determine the corresponding optimal tuner state action, ensuring that tuning optimality is maintained despite switch state changes.
Solution Approach 2:
The patent implements feedback mechanisms where runtime measurements of antenna performance are continuously monitored and fed back to the communication control circuit. This feedback enables the system to adjust both switch and tuner states dynamically, ensuring that any switch state change is accompanied by the optimal tuner state adjustment to maintain overall performance.
3Reliability
If antenna tuning causes tuner state change, then antenna performance is adjusted, but variations in associated information for antenna selection occur
Solution Approach 1:
The patent performs preliminary action by pre-defining the relationships between tuner states and selection criteria in the database. This allows the system to predict how tuner state changes will affect selection information, enabling proactive adjustment of selection decisions to compensate for any information variations caused by tuning.
4Device complexity
If existing independent methods are used for antenna selection or tuning, then implementation is simpler, but system performance is not optimized
Solution Approach 1:
The patent combines antenna selection and tuning control into a single integrated architecture where the communication control circuit performs joint decision-making. This unified approach, while increasing architectural complexity, achieves superior system performance by considering both selection and tuning objectives simultaneously rather than independently.
