Solution Overview
Problem
The increasing heat generation from electronic elements in compact electronic apparatuses poses a challenge for effective heat dissipation, potentially leading to overheating and damage, while also requiring enhanced mechanical strength and ergonomic design.
Innovation Solution
An electronic apparatus shell cover with a dust blocking screen and structural ribs that increase internal space, mechanical strength, and heat exchange efficiency, featuring a coplanar screen surface, assembling grooves and parts, and adjustable pads and cushions for improved ergonomics and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the internal space of the electronic apparatus is reduced to make it compact, then the portability is improved, but the heat dissipation capability deteriorates
Solution Approach 1:
The dust blocking screen is designed with a coplanar screen surface that extends to the first surface of the body, utilizing the surface dimension rather than occupying internal volume. This dimensional repositioning allows the heat dissipation function to be achieved without reducing the internal accommodating space, resolving the contradiction between compact size and heat dissipation capability.
2Strength
If structural ribs are added to increase mechanical strength, then the strength is improved, but the internal accommodating space is reduced
Solution Approach 1:
The structural ribs are designed as thin protrusions on the dust blocking screen rather than thick internal supports. This thin-film approach provides the necessary mechanical strength to prevent deformation while minimizing the space occupied, thus maintaining the internal accommodating space for electronic elements.
3Ease of manufacture
If the dust blocking screen is positioned below the first surface to simplify assembly, then the manufacturing ease is improved, but the internal accommodating space is reduced
Solution Approach 1:
Instead of positioning the dust blocking screen in the internal volume below the first surface, the screen surface is designed to extend coplanarly to the first surface. This repositioning in the surface dimension eliminates the need for complex internal mounting structures while maximizing the internal accommodating space.

AI summary
An electronic apparatus shell cover includes a body, a dust blocking screen, and a plurality of structural ribs. The body includes an opening and a plurality of assembling grooves. The opening penetrates through the body. The assembling grooves are on a second surface of the body and adjacent to the opening. The dust blocking screen includes a screen surface and a plurality of assembling parts. The screen surface is mounted in the opening and coplanar with a first surface of the body. The assembling parts are disposed in the assembling grooves. The structural ribs are connected to the first surface of the body and on the dust blocking screen. The dust blocking screen is coplanar with the first surface, and the internal accommodating space of the electronic apparatus shell cover is increased. Furthermore, the structural ribs can increase mechanical strength of the shell cover, can enhance heat exchange efficiency.
