Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile terminal is held by a user's hand, then the terminal can be operated conveniently, but the antenna performance deteriorates due to hand attenuation
Solution Approach 1:
The system pre-establishes a correspondence relationship between multiple holding states and multiple antennas before actual use. When a touch action is detected, the system quickly determines the current holding state and switches to the predetermined optimal antenna configuration, avoiding real-time complex calculations and achieving fast response.
Solution Approach 2:
The system dynamically switches between different antennas based on the detected holding state. The antenna configuration is not fixed but adapts to the user's holding posture, transitioning between different antenna elements to maintain optimal performance in various handheld scenarios.
2Reliability
If multiple antennas are deployed to improve wireless performance, then the antenna coverage increases, but the device complexity increases
Solution Approach 1:
The antenna system is divided into multiple independent antenna elements, each optimized for specific holding scenarios. The correspondence relationship table segments the solution space by mapping specific holding states to specific antenna configurations, making the complex multi-antenna system manageable through structured pre-computation.
Solution Approach 2:
The system pre-computes and stores the optimal antenna configurations for various holding states in a correspondence relationship table during the design phase. This eliminates the need for real-time complex optimization calculations, reducing the computational burden and system complexity during actual operation.
3Device complexity
If the antenna configuration is fixed, then the device complexity is reduced, but the wireless performance deteriorates in different holding states
Solution Approach 1:
The antenna configuration transitions from a fixed design to a dynamic one that adapts to the detected holding state. The system maintains simplicity by using a pre-computed correspondence table rather than real-time optimization, allowing the antenna configuration to change based on user interaction while keeping the control logic straightforward.
Solution Approach 2:
The system implements feedback by detecting the holding state through touch sensors and using this information to select the appropriate antenna configuration from the correspondence relationship table. This closed-loop approach ensures the antenna system responds to user holding patterns while maintaining simple control through pre-established mappings.
