Insertion Aperture Cover With Arc Slider for Small-Gap Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective structures for electronic apparatus insertion apertures require a larger turning radius and gap to avoid contact with the concavity sides, compromising protection and aesthetics.
Innovation Solution
An electronic apparatus with a concavity and a cover featuring an arc-shaped slider that contacts a support at the bottom surface, allowing the cover to rotate with a smaller turning radius and range, thus minimizing the gap needed between the cover and the concavity sides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the depth of the concavity is increased to provide better protection for the insertion aperture, then the protection level is improved, but the turning radius of the cover must be increased, requiring a larger gap between the cover and the side wall of the concavity, which worsens the aesthetic appearance and reduces protection effectiveness
Solution Approach 1:
The patent applies curvature by providing the support at the bottom surface of the concavity with a curved surface that corresponds to the arc-shaped cross-section of the slider. This curved surface guides the slider during rotation, enabling the cover to rotate with a small turning radius while maintaining a small gap between the cover and the side wall of the concavity, thus resolving the contradiction between protection level and gap size.
2Ease of operation
If the gap between the cover and the side wall of the concavity is widened to avoid contact during cover rotation, then the ease of operation is improved, but the protection level and aesthetic appearance are worsened
Solution Approach 1:
The curved surface of the support matches the arc-shaped slider, providing a guided rotation path that allows the cover to rotate smoothly with a small turning radius. This enables easy cover removal operation while maintaining a small gap between the cover and the side wall, thus improving ease of operation without sacrificing protection level.
3Device complexity
If a conventional cover rotation mechanism is used, then the device complexity is low, but the range of motion of the cover is large, requiring a larger gap that worsens protection and aesthetics
Solution Approach 1:
The patent uses a simple curved surface on the support that corresponds to the arc-shaped slider, creating a guided rotation mechanism. This simple curved guide constrains the cover's range of motion to a small arc, reducing the gap requirement while maintaining low device complexity as no additional complex mechanisms are needed.

AI summary
An electronic apparatus includes: a front surface member that includes a concavity in which an insertion aperture is located, the insertion aperture for receiving an object to be inserted into the insertion aperture, a bottom surface of the concavity having a support; and a cover that removably fits into the concavity to cover the insertion aperture. The cover includes a slider having an arc-shaped cross section. In a state in which the cover is fitted in the concavity, the slider of the cover contacts the support provided at the bottom surface of the concavity. When a part of the cover is pushed, the cover rotates, while the slider slides along a surface of the support.
