Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing base station interface devices face challenges in efficiently utilizing space, miniaturization, and management due to the layered arrangement of signal matching and processing units, which complicates installation and maintenance, and makes it difficult to maintain a stable connection between these units as they are connected by cables.
Innovation Solution
A base station interface device design featuring a housing with an interface board that allows for the compact arrangement of signal matching and processing units in the same plane, using a relay connector with tapered portions to securely connect these units without cables, and includes a control unit to sense electrical connections and drive a fan for heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the base station signal matching unit and base station signal processing unit are arranged in layers and connected by cables, then the connection between units is established, but the space utilization is inefficient and the device cannot be miniaturized
Solution Approach 1:
The patent transitions from a three-dimensional layered arrangement to a two-dimensional planar arrangement on the interface board. The base station signal matching unit and base station signal processing unit are both mounted on the same interface board in a planar configuration, eliminating the need for vertical stacking and reducing overall device volume while maintaining functional connectivity.
Solution Approach 2:
The patent extracts the cable connection between units and replaces it with integrated trace connections on the interface board. The relay connector and its associated traces are built into the board structure, removing external cables and reducing spatial requirements while maintaining signal transmission functionality.
2Ease of operation
If the signal matching unit and signal processing unit are connected by cables, then the connection is established, but the installation and management become difficult
Solution Approach 1:
The patent merges the cable connection function into the interface board structure itself. The relay connector and signal traces are integrated onto the same board where the signal matching unit and signal processing unit are mounted, eliminating separate cable management and simplifying installation to a single board-level operation.
3Reliability
If the signal matching unit and signal processing unit are connected by cables, then the connection is established, but the connection protection from outside damage is insufficient
Solution Approach 1:
The patent implements a nested connector structure where the second connector is inserted into the relay connector, which itself is mounted on the interface board. This nested arrangement provides multiple levels of mechanical protection and electrical contact, enhancing connection reliability while keeping the overall structure compact and integrated.
