Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connection and assembly methods are used for antenna modules and RRH, then electrical connection is achieved, but installation time and cost increase greatly
Solution Approach 1:
The connection mechanism is divided into separate functional components: sliding blocks for mechanical positioning, push blocks for actuation, and spring-loaded electrical contacts. This segmentation allows each component to perform its specific function efficiently, reducing overall installation time while maintaining reliable electrical connection.
Solution Approach 2:
The electrical contacts are pre-positioned and spring-loaded within the RRH and antenna module before assembly. The sliding blocks are pre-equipped with positioning features. When assembled, these pre-prepared components automatically engage and establish electrical connection without requiring additional connection steps, significantly reducing installation time.
2Reliability
If conventional assembly methods are used for antenna modules and RRH, then connection is achieved, but installation cost increases greatly
Solution Approach 1:
The sliding block serves multiple functions simultaneously: it provides mechanical positioning of the RRH relative to the antenna module, guides the insertion motion, and actuates the push block to engage electrical contacts. This multi-functionality reduces the number of separate components needed, lowering manufacturing and installation costs while ensuring reliable connection.
Solution Approach 2:
The spring-loaded electrical contacts automatically engage when the sliding block moves into position, and the push block self-actuates through the sliding motion itself. No additional tools, fasteners, or connection steps are required during installation. The system performs its own connection function through the inherent mechanics of the assembly motion, reducing labor costs and simplifying installation.
3Reliability
If conventional coupling structures are used for RRH assembly, then electrical connection is established, but coupling time is extended
Solution Approach 1:
The mechanical coupling and electrical connection functions are merged into a single integrated action. As the sliding block moves horizontally to position the RRH, it simultaneously actuates the push block to engage the electrical contacts. This combined motion eliminates separate steps for mechanical assembly and electrical connection, dramatically increasing coupling speed while ensuring reliable signal connection.
Solution Approach 2:
The push block acts as an intermediary mechanism that translates the horizontal sliding motion into vertical engagement of the electrical contacts. This intermediary converts the primary assembly motion into the secondary connection action, allowing both mechanical coupling and electrical connection to occur during a single continuous motion, thereby accelerating the overall coupling process.
4Reliability
If conventional connection mechanisms are used for antenna module and RRH, then electrical connection is achieved, but ease of operation is reduced
Solution Approach 1:
The complex multi-step connection process is extracted and replaced by a single intuitive pushing motion. The push block provides a large, easy-to-grasp surface that requires minimal force and precision from the operator. This extracted simplification maintains reliable electrical connection through the spring-loaded contacts while dramatically improving ease of operation by reducing the skill and effort required.

AI summary
A base station antenna device includes an antenna module having a separation space spaced a predetermined distance forward from a support pole, a remote radio head (RRH) provided on the rear surface of the antenna module such that the RRH is slidably assembled in a detachable manner in a horizontal direction from a lateral side of the separation space, and an adapter having a push block provided on a lower end portion of the RRH so as to mediate the electrical signal connection and disconnection between the antenna module and the RRH by means of a pushing operation in the longitudinal direction.
