Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple mechanical interfaces and drive devices are used for each frequency band or sector, then beam characteristics can be adjusted for each band or sector independently, but device complexity and cost increase significantly
Solution Approach 1:
The patent implements a single multi-beam shaping device that can control multiple antenna beams across different frequency bands and sectors. The device uses one drive unit with a multi-gear transmission system that provides multiple output shafts, each capable of independently adjusting beam characteristics for different bands or sectors. This universal approach eliminates the need for separate drive devices for each band, reducing device complexity while maintaining full adaptability.
Solution Approach 2:
The transmission system is segmented into multiple independent gear trains within a single device housing. Each gear train has its own output shaft that can be selectively connected to different antenna beams. This segmentation allows independent control of multiple beams while using a single integrated drive unit, resolving the contradiction between versatility and complexity.
2Device complexity
If a single drive unit with multi-gear system is used, then device complexity and cost are reduced, but the ability to independently adjust multiple beams simultaneously is limited
Solution Approach 1:
The patent employs a dynamic switching mechanism where the single drive unit can selectively engage different output shafts based on control signals. The multi-gear transmission system allows the drive unit to dynamically allocate its output to different antenna beams as needed, enabling independent adjustment of multiple beams through sequential or selective operation rather than requiring simultaneous independent drive units.
Solution Approach 2:
The multi-gear transmission system acts as an intermediary between the single drive unit and multiple antenna beams. It provides multiple output shafts that can be selectively connected to different beams, mediating the control function and enabling a single drive unit to effectively control multiple beams independently through selective engagement of different gear trains.
3Measurement precision
If multiple separate actuators are used for each band or sector, then precise independent control is achieved, but manufacturing cost and installation complexity increase
Solution Approach 1:
The patent merges multiple actuator functions into a single integrated multi-beam shaping device. The device combines a single drive unit with a multi-gear transmission system that provides multiple output shafts, each capable of precise beam angle control. This merging maintains the precision of individual actuators while significantly reducing manufacturing cost and installation complexity by eliminating the need for multiple separate actuator assemblies.
Solution Approach 2:
The single multi-beam shaping device serves multiple functions that would traditionally require separate actuators. It can control beam characteristics for multiple frequency bands and sectors through its multiple output shafts, providing universal control capability that reduces both manufacturing and installation costs while maintaining precise control for each band or sector.
