Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mutual interference occurs between multiple antennas in a computer host, affecting their transmitting and receiving efficiency.
Innovation Solution
The antennas are arranged with a predetermined separation distance and orthogonal orientation, with some being made of insulating materials and positioned to avoid sheltering by metal parts, using inverted-F antenna designs with specific configurations to minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple antennas are placed close together in a computer host, then the device complexity is reduced and space is saved, but mutual interference occurs between antennas affecting transmitting and receiving efficiency
Solution Approach 1:
The patent positions antennas in three-dimensional space with specific spatial relationships - placing Wi-Fi antennas on the top surface and X-Box antennas on the front surface, utilizing vertical and angular separation to reduce interference while maintaining compact form factor
Solution Approach 2:
The patent assigns different orientations and positions to different antenna groups based on their specific functions - Wi-Fi antennas are positioned with specific polarization orientations while X-Box antennas are positioned for optimal gaming console communication, optimizing each antenna's local performance
2Volume of moving object
If antennas are positioned without proper separation, then the device size is minimized, but isolation between antennas deteriorates leading to interference
Solution Approach 1:
The patent utilizes three-dimensional positioning to achieve isolation without increasing overall device volume - by placing antennas on different surfaces (top vs front) and utilizing vertical spacing, the patent achieves separation in multiple dimensions while maintaining compact form factor
Solution Approach 2:
The patent employs asymmetric positioning where Wi-Fi antennas are placed on the top surface while X-Box antennas are placed on the front surface, creating unequal spatial distribution that effectively reduces mutual interference while optimizing space utilization

AI summary
A host with multiple antennas so as to be capable of Wi-Fi and X-box functioning includes a chassis, and first to fourth antennas. The first antenna and the second antenna are each on an edge area of a first side wall of the chassis, the third antenna is located on a second side wall of the chassis, and the fourth antenna is located on a third side wall of the chassis. The first side wall is located between the second side wall and the third side wall, and the second side wall is located opposite to the third side wall. A separation distance between every two antennas of the first to fourth antennas is greater than a predetermined distance and enables isolation requirements for all antenna types to be met.
