Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The recent shift to DDR5 memory, operating within a frequency range that overlaps with Wi-Fi 6E frequencies, causes interference with network communication in desktop computers, leading to noise generation around the 6000 MHz frequency band.
Innovation Solution
An antenna assembly with a shielding body and antenna body is designed to be assembled on desktop computers, featuring a shielding layer and structure that shields the frequency interference, reducing noise and enhancing wireless communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If DDR5 memory is used to achieve higher data transfer speeds, then memory performance is improved, but frequency interference with Wi-Fi 6E communication occurs
Solution Approach 1:
A shielding body is introduced as an intermediary component between the DDR5 memory and the Wi-Fi 6E antenna. The shielding body includes a shielding layer that selectively blocks the 5150-7125 MHz frequency band while allowing other frequencies to pass through, thereby mediating the interference between memory operations and wireless communication
Solution Approach 2:
The shielding body is positioned locally near the antenna assembly, specifically between the memory module and the Wi-Fi 6E antenna. This localized shielding approach targets only the specific frequency interference path without affecting the overall system performance or requiring comprehensive shielding of the entire computer case
2Reliability
If shielding structures are added to block frequency interference, then communication quality is improved, but device complexity increases
Solution Approach 1:
The shielding body serves multiple functions: it blocks the 5150-7125 MHz frequency band from DDR5 memory interference, maintains structural support for the antenna assembly, and can be integrated with existing chassis components. This multi-functionality reduces the need for additional separate shielding components, thereby limiting the increase in device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The antenna assembly effectively reduces interference from the DDR5 memory's frequency range, thereby improving the efficiency of wireless communication by minimizing noise in the 6000 MHz band.
Implementation Method 1
The shielding layer is coated on at least two first side surfaces and at least two second side surfaces of the insulated body so as to create the two first shielding walls and the two second shielding walls
