Retractable Protective Case Stand for Stable Multi-Angle Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld device stands, particularly those for larger phones and tablets, lack flexibility and stability, often resulting in poor viewing angles and increased risk of accidental drops due to their design and material limitations, such as the 'ring-type' stands which are not ergonomic and not aesthetically pleasing.
Innovation Solution
A retractable stand with a base system utilizing elastic sheets and a limiting device that allows for adjustable positioning, enabling the stand to be raised or lowered while maintaining a compact form factor, providing support and optimal viewing angles without protruding excessively, and integrating seamlessly with protective cases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a ring-type stand is used, then the stand can be attached to the back of the phone, but the stand cannot provide good viewing angles and cannot support larger tablets
Solution Approach 1:
The stand is divided into multiple independent support legs that can be individually adjusted, allowing each leg to be positioned independently to achieve optimal viewing angles and support various device sizes and orientations
Solution Approach 2:
The support legs are designed to be movable and adjustable rather than fixed, enabling dynamic repositioning to accommodate different viewing preferences and device configurations
2Reliability
If a ring-type stand is used, then the stand can support the phone, but the stand protrudes excessively and is not aesthetically pleasing
Solution Approach 1:
The support legs are designed to nest within or alongside each other when not in use, allowing the stand to maintain a compact, uniform profile that does not protrude excessively from the device back surface
Solution Approach 2:
The stand utilizes flexible material that allows the support legs to be thin and sleek when retracted, maintaining aesthetic appearance while providing sufficient structural support when deployed
3Shape
If a retractable stand is used, then the stand can be compact when not in use, but the stand cannot provide stable support for larger tablets
Solution Approach 1:
The stand uses multiple segmented support legs that can be extended and positioned independently, providing distributed support across multiple contact points to stabilize larger tablets while maintaining compactness when retracted
Solution Approach 2:
The support legs utilize three-dimensional spatial arrangement and angular positioning to achieve stable support for larger devices while maintaining a compact two-dimensional profile when retracted
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The stand offers improved ergonomic support, stability, and aesthetic appeal by allowing for flexible positioning of handheld devices in both portrait and landscape modes, reducing the risk of drops and ensuring a compact, uniform profile when not in use.
Implementation Method 1
an elevating device between the first base and the second base. The elevating device includes a limiting device

AI summary
The invention relates to a stand for a hand-held device and a protective case comprising the stand. The stand comprises a first base, a second base, a first elastic sheet, a second elastic sheet and a limiting device. The first ends of the first elastic sheet and the second elastic sheet are respectively arranged on the two sides of the first base. The limiting device enables the second end of the first base and the second end of the second base to slide separately and not overlap each other within a limited range. When the second end of the first elastic sheet and the second end of the second elastic sheet carry out a first relative displacement, the first base and the second base forms a second relative displacement.
