Electronic Apparatus Cooling Module With Integrated Antenna Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic apparatuses like laptops and tablets, the miniaturization demand often prevents the installation of a shield box around electronic parts to protect the antenna from electromagnetic wave noise generated by components like memories, as there is insufficient space for such shielding due to the layout of parts.
Innovation Solution
A metal plate-shaped cooling module with a shield wall is integrated between the antenna and electronic parts to provide electromagnetic shielding, utilizing the cooling module's structure to create a shield between the antenna and memory, enhancing the chassis's miniaturization without compromising shielding performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shield box is installed around the memory to block electromagnetic waves, then the antenna reception sensitivity is improved, but the chassis size increases and miniaturization is hindered
Solution Approach 1:
The patent merges the shielding function with the cooling module by integrating a shield wall into the cooling module's structure. The cooling module, which already occupies necessary space for thermal management, is enhanced to provide electromagnetic shielding between the memory and antenna, thereby eliminating the need for a separate shield box and preventing additional chassis volume increase.
Solution Approach 2:
The cooling module is designed to serve multiple functions: it provides thermal management for the memory while simultaneously acting as an electromagnetic shield between the memory and the antenna. This multi-functionality allows the chassis to maintain miniaturization while ensuring both cooling and shielding requirements are met.
2Volume of moving object
If the chassis is miniaturized to meet size demands, then the device compactness is improved, but the installation space for shield boxes and clips is reduced
Solution Approach 1:
The shielding function is merged into the cooling module structure, which is already a necessary component for thermal management. By integrating the shield wall into the cooling module, the patent eliminates the need for separate shielding components and their associated installation space, thereby enabling chassis miniaturization without compromising manufacturing ease.
3Volume of moving object
If the antenna and memory are arranged close to each other due to layout constraints, then the chassis compactness is improved, but electromagnetic interference between the antenna and electronic parts increases
Solution Approach 1:
The shield wall integrated into the cooling module acts as an intermediary between the memory and the antenna. This intermediate structure blocks electromagnetic waves from the memory, preventing interference with the antenna while allowing the two components to be positioned close together for compact chassis design.
