Antenna and Exhaust Duct Overlap in Tablet Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited space on the side surfaces of tablet PCs restricts the layout design of various terminals, making it difficult to integrate both internal antenna elements and air-cooled type cooling mechanisms effectively.
Innovation Solution
The integration of an air-cooled type cooling mechanism, which includes a heat source, heat dissipation member, heat conduction member, cooling fan, exhaust port, and exhaust duct, allows for the efficient discharge of heat while positioning the antenna elements to overlap with the exhaust duct in the thickness direction, thereby saving space and enhancing layout flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an air-cooled type cooling mechanism is implemented in a tablet PC, then heat dissipation performance is improved, but the limited side surface area restricts terminal layout design freedom
Solution Approach 1:
The patent applies dimensionality change by allowing the antenna element and exhaust duct to overlap in the thickness direction (vertical dimension) rather than requiring them to be arranged side-by-side on the limited side surface (horizontal plane). This three-dimensional spatial arrangement resolves the contradiction by utilizing the Z-axis dimension to accommodate both the cooling mechanism and antenna element without compromising side surface terminal layout freedom.
2Adaptability or versatility
If the side surface area is used for terminal layout, then terminal functionality is provided, but space for internal components is reduced
Solution Approach 1:
The patent resolves this contradiction by transitioning from two-dimensional side surface arrangement to three-dimensional overlapping arrangement in the thickness direction. This allows the antenna element and exhaust duct to coexist in the vertical dimension without consuming additional side surface area, thereby preserving both terminal layout flexibility and internal component space.

AI summary
The electronic device includes a case, an antenna element, a heat source, a heat dissipation member, a heat conduction member, a cooling fan, an exhaust port, and an exhaust duct. The case has a pair of main surfaces and side surfaces. The antenna element is used to perform wireless communication. The heat dissipation member exchanges heat with a cooling wind. The heat conduction member conducts heat of the heat source to the heat dissipation member. The cooling fan generates the cooling wind to be blown to the heat dissipation member. The exhaust port is an exhaust port from which the cooling wind is discharged to the outside. The exhaust duct guides the cooling wind to the exhaust port. The exhaust port is disposed on one of the side surfaces, and the antenna element and the exhaust duct are disposed to overlap each other at least partially in the thickness direction.
