Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional beam width adjustment mechanism is used, then beam width adjustment is achieved, but the mechanism is complex, occupies large space, and encounters significant resistance
Solution Approach 1:
The patent combines the phase shifter and connecting plate into an integrated beam adjustment assembly. The connecting plate is slidably assembled on the circuit board of the phase shifter, merging two previously separate components into one unified structure. This integration reduces the number of separate adjustment mechanisms, simplifies the overall device complexity, and eliminates the need for separate beam width adjustment mechanisms while maintaining adjustment functionality.
2Ease of operation
If a conventional beam width adjustment mechanism is used, then beam width adjustment is achieved, but it occupies relatively large space
Solution Approach 1:
By merging the phase shifter and connecting plate into a single integrated assembly, the patent significantly reduces the space required for beam adjustment functionality. The connecting plate utilizes the existing circuit board structure of the phase shifter, eliminating the need for separate adjustment mechanisms and reducing overall space occupation in the antenna system.
3Ease of operation
If a conventional beam width adjustment mechanism is used, then beam width adjustment is achieved, but it encounters relatively large resistance in adjustment
Solution Approach 1:
The integrated design of the phase shifter and connecting plate allows for coordinated movement that reduces friction and resistance. The sliding connection of the connecting plate on the circuit board is designed to work in conjunction with the phase shifter's internal mechanisms, creating a unified adjustment system that encounters less resistance compared to separate adjustment mechanisms.
4Area of stationary object
If the connecting plate is integrated in the phase shifter, then space occupation is reduced and operation is easier, but the mechanism requires precise sliding control
Solution Approach 1:
The patent employs a sliding connection mechanism that allows dynamic adjustment of the connecting plate position on the circuit board. This dynamic design enables precise control through controlled movement rather than fixed positioning, allowing for accurate beam adjustment while maintaining the space-efficient integrated structure. The sliding mechanism provides continuous adjustability with precise control capability.

AI summary
A beam adjustment assembly includes a phase shifter and a connecting plate. The phase shifter includes a circuit board and main dielectric slabs configured to shift a phase. The circuit board is provided with a first strip and a second strip that are spaced. The first strip and the second strip are configured to respectively connect to radiating elements of an antenna. The connecting plate is slidably assembled on the circuit board and is configured to control an electrical connection between the first strip and the second strip. When sliding, the main dielectric slab can push the connecting plate to slide to control a quantity of radiating elements in the antenna system. The sliding of the main dielectric slab in the phase shifter is used as a driving mechanism of the connecting plate.
