Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the structural state of the electronic device changes, then the adaptability of the device is improved, but the radio transmission and reception performance of the satellite communication antenna deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the antenna structure adaptable to different structural states of the foldable device. The antenna is configured to change its radiation direction according to the folded or unfolded state, allowing the system to dynamically adjust its electromagnetic radiation pattern to maintain reliable satellite communication despite structural changes.
2Manufacturing precision
If the antenna radiation direction is fixed, then the manufacturing precision is improved, but the adaptability to different device orientations deteriorates
Solution Approach 1:
The antenna is designed with dynamic orientation capability that allows it to adjust its radiation direction based on the device's structural state. In folded state, the antenna radiates in a first direction, and in unfolded state, it radiates in a second direction, enabling reliable communication across different orientations while maintaining precise control over radiation patterns.
Solution Approach 2:
The patent changes the radiation direction parameter of the antenna according to the device's structural state. By adjusting the radiation direction parameter between folded and unfolded states, the system maintains optimal satellite communication performance across different device configurations and orientations.
