Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to coordinate the assembly relationship between the passive antenna and the active radio frequency portion in communication base stations, particularly due to changing size requirements and the inefficiencies caused by integrated water-proof edges, which complicate machining and assembly processes.
Innovation Solution
A communication base station design that includes a radome, an adapter board, and a radiator, where the adapter board facilitates the separation of the radome and radiator, allowing for independent size adjustments based on performance requirements, and incorporates a shielding structure to prevent electromagnetic interference, with a water-proof rubber strip for outdoor use, and screw holes for easy mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radome and radiator are integrated with a water-proof edge, then waterproofing is ensured, but the machining and assembly processes become complicated
Solution Approach 1:
The patent divides the integrated structure into separate components: the radome, the radiator, and the adapter board. The adapter board acts as an independent component that connects the radome and radiator, eliminating the need for a complex integrated water-proof edge. This segmentation allows each component to be manufactured and assembled independently, simplifying the overall production process while maintaining waterproofing through dedicated sealing structures.
2Stability of the object's composition
If the radome and radiator are designed as a unified structure, then structural stability is improved, but independent size adjustments based on performance requirements become difficult
Solution Approach 1:
The adapter board introduces flexibility into the structure, allowing the radome and radiator to be independently sized according to their respective performance requirements. The adapter board can be designed with different dimensions and configurations to accommodate various antenna and radio frequency component sizes, enabling the system to adapt to different performance needs while maintaining structural integrity through the connecting mechanism.
3Device complexity
If the connector is mounted on the radiator without an adapter board, then the structure is simpler, but the machining tool operation and connector mounting become inconvenient
Solution Approach 1:
The adapter board serves as an intermediary component between the radiator and the connector. It provides a dedicated mounting surface and positioning features that facilitate convenient connector installation and machining tool access. The adapter board can be designed with optimized geometry to allow easy access for machining operations and simple connector mounting, while still maintaining a relatively simple overall structure.
