Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna is placed on the lid or base in laptop mode, then the wireless communication performance is optimized for laptop mode, but the performance drops in closed-lid mode and tablet mode
Solution Approach 1:
The patent implements a rotatable antenna mounting structure that allows the antenna to dynamically change its orientation between different use case modes (laptop mode, closed-lid mode, tablet mode). The antenna can be rotated to different positions to optimize wireless communication performance for each specific mode, transforming a static antenna placement into a dynamic, adaptable system.
Solution Approach 2:
The patent changes the physical orientation parameter of the antenna by implementing a rotatable mounting mechanism. This allows the antenna to adjust its directional characteristics and radiation pattern according to different use case modes, effectively changing the antenna's operational parameters to maintain optimal performance across various device configurations.
2Volume of moving object
If the antenna is positioned close to the metal chassis, then the device design is compact and thin, but the antenna performance degrades due to interference
Solution Approach 1:
The patent addresses the interference problem by changing the spatial dimension of antenna placement. Instead of only considering horizontal positioning on the lid or base, the invention utilizes the vertical dimension by implementing a rotatable mounting structure that can orient the antenna at different angles relative to the metal chassis, thereby reducing electromagnetic interference while maintaining compact device design.
Solution Approach 2:
The rotatable mounting structure acts as an intermediary between the antenna and the metal chassis. This intermediate mechanism allows the antenna to be positioned close to the chassis for compact design while simultaneously enabling the antenna to rotate to orientations that minimize interference, effectively mediating between the conflicting requirements of compactness and performance.
3Device complexity
If a fixed antenna orientation is used, then the device structure is simple, but the wireless communication throughput decreases in non-laptop modes
Solution Approach 1:
The patent transforms the static antenna mounting structure into a dynamic one by adding a rotation mechanism. This allows the antenna to adapt its orientation based on the device's use case mode, thereby maintaining high wireless communication throughput across different modes while accepting the increased structural complexity necessary to enable this adaptability.
