Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antennas are used to cover multiple transmitting/receiving orientations, then the wireless communication reliability is improved, but the device size increases and battery capacity decreases
Solution Approach 1:
The patent applies the dynamics principle by making the antenna module rotatable rather than fixed. A single antenna module can dynamically adjust its orientation to different transmitting/receiving directions through rotation, replacing the need for multiple fixed antennas. This dynamic adjustment capability allows the system to maintain reliable wireless communication across multiple orientations while using only one antenna module, thereby reducing device size and preserving battery capacity.
2Reliability
If multiple antennas are used to cover multiple transmitting/receiving orientations, then the wireless communication reliability is improved, but the battery capacity decreases
Solution Approach 1:
The dynamics principle is applied by enabling the antenna module to rotate and adjust its orientation dynamically. This allows a single antenna module to serve multiple transmitting/receiving orientations that would otherwise require multiple fixed antennas. By reducing the number of antenna modules from multiple to one, the space previously occupied by additional antennas and their associated components can be used to accommodate a larger battery, thus improving battery capacity while maintaining communication reliability.
3Speed
If beam forming is used to improve signal transmission, then the transmission speed is improved, but the communication fails when beams cannot be transmitted in a specific direction
Solution Approach 1:
The patent combines beam forming technology with a rotatable antenna module. The antenna module can rotate to dynamically adjust its beam transmission direction, ensuring that high-speed millimeter wave communication can be maintained regardless of the relative orientation between the wireless communication device and the base station. This dynamic orientation adjustment prevents communication failure due to misaligned beams while preserving the high transmission speed benefits of beam forming.
Solution Approach 2:
The patent applies parameter changes by adjusting the orientation parameter of the antenna module through rotation. By changing the angular parameter of the antenna, the system can adapt the beam transmission direction to match the optimal path between the device and base station, maintaining both high transmission speed and reliable communication connection.
4Volume of moving object
If the antenna module width is reduced to save space, then the device size is reduced, but the signal reception capability may be affected
Solution Approach 1:
The patent applies the dynamics principle by making the antenna module rotatable. This allows a compact, narrow antenna module to achieve the performance of a larger antenna by dynamically adjusting its orientation to face the base station directly. The rotation capability compensates for the reduced antenna size, maintaining signal reception capability while enabling a smaller overall device form factor.
