Electronic Apparatus Frame Cover Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic apparatuses with conventional attachment structures expose screw insertion locations when placed vertically, compromising aesthetics and requiring excessive fixation points, which can lead to rigidity and attachment strength issues.
Innovation Solution
The electronic apparatus employs a frame with a peripheral wall to attach internal components, covered by first and second covers, where the covers are fixed to the frame using fewer screws, ensuring the insertion locations of fixtures are not exposed and reducing the overall number of fixation points needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fix the upper and lower housings directly, then the attachment strength is sufficient, but the screw insertion locations become exposed and compromise appearance when placed vertically
Solution Approach 1:
The housing is divided into upper and lower covers that are attached to a frame structure. The frame acts as an intermediate structure that distributes attachment points away from visible surfaces, segmenting the attachment function from the visible housing surfaces.
Solution Approach 2:
A frame structure is introduced as an intermediary between the covers and the internal components. This frame provides alternative attachment locations on its inner peripheral face, which are not visible when the apparatus is placed vertically, thus mediating between the need for secure attachment and aesthetic appearance.
2Stability of the object's composition
If multiple screws are used to ensure rigidity and attachment strength, then the structural integrity is improved, but the number of exposed fixation points increases
Solution Approach 1:
The attachment points are moved from the external visible surfaces to the internal structure of the frame. By utilizing the inner peripheral face of the frame as an attachment surface, the screws are positioned in a different spatial dimension (inside the housing structure) where they do not compromise appearance while maintaining rigidity.
3Ease of manufacture
If screws are inserted from the lower face for easy assembly, then the ease of manufacture is improved, but the insertion locations stand out and are unfavorable in appearance when placed vertically
Solution Approach 1:
Instead of attaching covers to each other from the outside, the invention inverts the attachment approach by having both covers attach to an internal frame structure. This allows assembly to proceed from the inside out, with screws inserted from accessible locations on the frame rather than from visible external surfaces.

AI summary
An electronic apparatus includes: a first cover having a first face portion that covers a plurality of parts built in the electronic apparatus, and a first peripheral face portion which provides a first portion of an outer peripheral face of the electronic apparatus; a second cover having a second face portion that covers the plurality of parts, and a second peripheral face portion which provides a second portion of the outer peripheral face of the electronic apparatus; a channel defined by a separation between the first cover and the second cover, where the first and second face portions are opposite to one another, a first peripheral edge of the first cover and a second peripheral edge of the second cover oppose one another and do not meet, thereby defining the separation between the first cover and the second cover; and a plurality of air vent holes located through at least one wall surface within the channel.
