Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compact base stations face challenges in achieving compactness and effective heat dissipation due to the stacking of major components, which leads to larger sizes and heat dissipation issues, particularly with the power amplification unit.
Innovation Solution
The compact base station design arranges boards in three dimensions within an enclosure and utilizes heat dissipation parts on the outer surfaces, allowing for efficient heat transfer and compactness, with power amplification units spaced apart for optimal heat dissipation and filters stacked to enhance antenna characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If major components are stacked one above another to reduce horizontal space, then the vertical height increases and heat dissipation becomes difficult, but the horizontal footprint is reduced
Solution Approach 1:
The patent transitions from vertical stacking to three-dimensional arrangement on enclosure surfaces. Boards are mounted on inner surfaces and heat dissipation parts are arranged on outer surfaces, utilizing the enclosure's surface area in multiple directions rather than stacking components vertically. This dimensional redistribution reduces both vertical height and improves heat dissipation by exposing more surfaces to ambient air.
Solution Approach 2:
The enclosure acts as an intermediary structure that facilitates heat dissipation. Heat dissipation parts are mounted on the outer surfaces of the enclosure, which serves as a thermal interface between the internal components and the external environment. The enclosure's outer surfaces act as mediators that transfer heat from internal boards to ambient air through convection and radiation.
2Device complexity
If power amplification units are integrated on one board to reduce component count, then the board size increases and heat dissipation problems arise, but the number of separate components is reduced
Solution Approach 1:
The patent segments power amplification units into separate boards rather than integrating them on one board. Multiple independent boards (first board, second board, third board) are mounted on different inner surfaces of the enclosure, distributing heat generation across multiple locations. This segmentation reduces heat concentration and improves dissipation while maintaining manageable component organization.
3Reliability
If filter cavities are arranged in a line to maintain antenna characteristics, then the horizontal and vertical dimensions increase, but the antenna performance is maintained
Solution Approach 1:
The patent arranges filter cavities in a three-dimensional configuration on the enclosure surfaces rather than in a linear arrangement. By utilizing the enclosure's outer surfaces in multiple directions, the filter structure achieves compact dimensions while maintaining the necessary cavity spaces for optimal antenna characteristics. This spatial redistribution reduces both horizontal and vertical footprints.
