Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antennas are provided to cover multiple transmitting/receiving orientations, then signal reception capability is improved, but device size increases and battery capacity decreases
Solution Approach 1:
The patent applies the dynamics principle by making the antenna module rotatable relative to the device body through a rotation mechanism. This allows a single antenna to dynamically adjust its orientation and cover multiple transmitting/receiving directions, eliminating the need for multiple fixed antennas while maintaining signal reception capability across different orientations.
2Reliability
If multiple antennas are provided to cover multiple transmitting/receiving orientations, then signal reception capability is improved, but battery capacity decreases
Solution Approach 1:
By implementing a rotatable antenna module that can dynamically orient itself, the patent reduces the quantity of antennas from multiple to a single adjustable antenna. This reduction in component quantity directly preserves battery capacity while maintaining comprehensive signal reception capability through the antenna's ability to rotate and align with incoming signals from different directions.
3Speed
If beam forming is used to transmit millimeter waves, then transmission speed is improved, but signal attenuation increases due to high directivity
Solution Approach 1:
The rotatable antenna module enables dynamic beam steering by physically rotating the antenna to align with the base station direction. This maintains the high directivity benefits of beam forming for fast transmission while reducing signal attenuation by actively tracking and pointing the beam toward the receiver, rather than relying on fixed high-directivity beams that may misalign.
Solution Approach 2:
The system incorporates feedback mechanisms to detect the orientation of base station signals and automatically adjusts the antenna module's rotation angle accordingly. This feedback loop ensures the beam remains optimally directed toward the base station, maintaining high transmission speed while compensating for signal attenuation by continuously aligning the high-directivity beam with the target.
4Volume of moving object
If a single antenna is provided, then device size is reduced, but signal reception fails when the antenna cannot transmit/receive in a specific direction
Solution Approach 1:
The patent resolves this contradiction by making the single antenna dynamic through a rotation mechanism. The antenna can change its orientation to face different directions, allowing it to maintain signal reception reliability across various scenarios while keeping the device compact. The rotation capability enables the single antenna to effectively cover multiple directions that would otherwise require multiple fixed antennas.
