Solution Overview
Problem
Electronic devices face challenges in achieving slimness and durability due to the minimum injection thickness requirement of metal frames, which hinders their portability and resistance to external impacts.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal frame is used to replace a plastic frame, then durability and strength are improved, but the minimum injection thickness requirement prevents the device from being thinner
Solution Approach 1:
The frame structure is divided into a main frame and a separate plate structure that is installed on the main frame. The plate has frames that are seated on recess portions of the main frame, creating a segmented assembly that achieves the required strength without requiring the entire frame to meet minimum injection thickness requirements.
Solution Approach 2:
The plate structure is installed on the surface of the main frame, utilizing the surface dimension rather than increasing the thickness dimension. The recess portions are formed along the frame of the opening portion lower than the surface of the main frame, allowing the plate to be mounted in a way that adds structural strength without increasing the overall device thickness.
2Length of moving object
If the frame thickness is reduced to achieve slimness, then portability is improved, but resistance to external impacts deteriorates
Solution Approach 1:
At least one of the frames of the plate is formed of a curved portion that is curved inwardly. This curved structure is designed to absorb external impacts by deforming in a controlled manner, preventing plastic deformation of the overall frame while maintaining a thin profile. The curvature allows the frame to flex and absorb impact energy without compromising structural integrity.
3Length of moving object
If a thin plate structure is used, then device slimness is improved, but structural integrity and resistance to deformation deteriorate
Solution Approach 1:
The plate structure is combined with the main frame through the recess portions and seating arrangement. The frames of the plate are seated on the recess portions of the main frame, creating a merged structural system where the thin plate gains support from the main frame and the overall structure achieves both slimness and structural integrity.
Solution Approach 2:
The curved portions are strategically positioned in the plate frames to provide localized impact absorption where needed. The recess portions in the main frame are formed at specific locations to provide optimal seating support for the plate frames. This local quality approach ensures structural integrity is maintained at critical points while keeping the overall device thin.

AI summary
An electronic device is provided. The electronic device includes a main frame, an opening portion formed in the main frame, a recess portion formed along a frame of the opening portion lower than a surface of the main frame, and a plate having frames seated on the recess portion, wherein at least one of the frames of the plate is formed of a curved portion that is curved inwardly. Accordingly, it is possible to absorb an external impact and prevent deformation just by a simple structure change of the plate.
