Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic device cases often restrict viewing angles to either landscape or portrait orientations, limiting versatility and requiring users to adjust the device manually for optimal viewing positions.
Innovation Solution
A portable electronic device support featuring a base and a frame with a rotational mechanism that allows 360-degree rotation, where the rotational mechanism is offset from the center to maintain a consistent viewing angle when switching between orientations, ensuring the device remains centered and adjustable between landscape and portrait positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a classical case providing only cover or shell function is used, then protection is provided, but support in different configurations or multiple viewing angles is not provided
Solution Approach 1:
The case incorporates a rotational mechanism that allows the frame to dynamically adjust between portrait and landscape orientations. The rotational joint enables the device holder to pivot 90 degrees while maintaining a consistent viewing angle, transforming a static protective case into a dynamic support structure that adapts to different viewing preferences without requiring multiple separate cases
Solution Approach 2:
The case design integrates multiple functions into a single structure: the base provides protection, the rotational mechanism enables orientation switching, and the frame with device holder offers stable viewing in both portrait and landscape modes. This multi-functional design eliminates the need for separate protective cases and viewing angle adjusters
2Adaptability or versatility
If supports providing multiple viewing configurations are used, then landscape and portrait orientations are enabled, but the device center shifts laterally between positions
Solution Approach 1:
The rotational mechanism is deliberately positioned asymmetrically relative to the base center, specifically offset along the longer dimension of the rectangular base. This asymmetric placement compensates for the lateral shift that would normally occur during rotation, ensuring that the device center remains stable at the same location on the base whether in portrait or landscape orientation
Solution Approach 2:
The solution addresses the lateral positioning problem by utilizing the rotational dimension. The asymmetric offset of the rotational mechanism allows the frame to rotate 90 degrees while the device center maintains its position along the base's longer dimension, effectively using rotational movement to compensate for positional shifts
3Ease of operation
If the rotational mechanism is centered on the frame, then rotation is symmetric, but the viewing angle changes when switching between orientations
Solution Approach 1:
The rotational mechanism is positioned asymmetrically on the frame, specifically offset from the center along the longer dimension. This asymmetric placement is calculated to maintain a consistent viewing angle of approximately 70 degrees from the base in both portrait and landscape orientations, prioritizing viewing angle stability over rotational symmetry
Solution Approach 2:
The design changes the positional parameter of the rotational mechanism from a centered location to an offset location. By adjusting this positional parameter, the viewing angle remains consistent across different orientations while enabling smooth 90-degree rotation between portrait and landscape modes

AI summary
In certain embodiments of the present invention, a portable electronic device support comprises a base, a frame, and a rotational mechanism, with the base including a front and a rear panel. The rotational mechanism is attached to the frame at a position offset from the center so that substantially the same viewing angle can be maintained after rotation from landscape to portrait orientation.
