Engineering Contradiction Analysis
1Productivity
If the number of antennas is increased to achieve Massive MIMO, then channel capacity and data transmission capability are improved, but power consumption and heat generation increase significantly
Solution Approach 1:
The antenna system is divided into multiple independent antenna elements arranged in a structured array. Each antenna element operates semi-independently, allowing the system to achieve high channel capacity through spatial multiplexing while distributing power consumption across multiple lower-power individual elements rather than requiring one high-power element
2Area of stationary object
If high power is used for coverage expansion in Massive MIMO, then signal coverage is improved, but heat generation increases causing negative factors in reducing weight and size
Solution Approach 1:
The patent transitions from traditional 2D planar antenna arrangements to a 3D spatial distribution of antenna elements. This three-dimensional configuration allows for better heat dissipation in multiple directions and improves coverage area by utilizing vertical and horizontal dimensions simultaneously, reducing heat concentration in any single plane
3Volume of moving object
If modules with RF elements and digital elements are combined in a stacked structure to maximize space utilization, then space efficiency is improved, but heat dissipation becomes more difficult due to confined space
Solution Approach 1:
The stacked structure is segmented into distinct functional layers with dedicated heat dissipation pathways for each layer. RF elements and digital elements are separated into different stacked modules, each with its own thermal management system. This segmentation allows heat to be dissipated from each layer independently rather than requiring heat to travel through the entire stack, maintaining compact form factor while improving heat dissipation efficiency
