Foldable Tablet Stand With Nested Legs for Comfortable Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices are difficult to view when held for extended periods or placed on a surface, as they often require manual support and can be challenging to position for optimal viewing.
Innovation Solution
A foldable tablet stand with a front pair of legs and a rear pair of legs that can pivot, allowing the device to be positioned upright or inclined, featuring a face plate with indicia for promotional purposes and a polyurethane dome for additional functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile device is held for extended periods to view data and media, then viewing is possible, but user fatigue increases
Solution Approach 1:
The stand enables the mobile device to support itself in an upright viewing position without requiring continuous manual holding. The device is placed on the stand and automatically maintains its position through the geometric configuration of the legs and feet, eliminating the need for user muscle support.
2Ease of operation
If the mobile device is placed on a table to avoid holding, then user fatigue is reduced, but viewing becomes difficult
Solution Approach 1:
The front foot extends transverse to the upright portion and the legs have arcuate profiles that create a curved, cradle-like structure. This curvature naturally guides and secures the mobile device in an optimal viewing position, making positioning intuitive rather than difficult.
3Volume of moving object
If a foldable stand structure is used to improve portability, then compactness is achieved, but structural complexity increases
Solution Approach 1:
The rear pair of legs nests within the gap between the front pair of legs when folded, creating a compact storage configuration. The smaller rear legs fit inside the space created by the larger front legs, maximizing compactness while using a simple hinge-based folding mechanism rather than complex articulation.
4Volume of moving object
If the rear pair of legs has width less than the gap of the front pair of legs, then compact folding is achieved, but stability may be compromised
Solution Approach 1:
The front pair of legs has a larger width and extends further forward to provide a broad, stable base for supporting the mobile device. The rear pair of legs has a smaller width optimized for nesting during folding. Each pair's dimensions are locally optimized for its specific function: the front legs for stability and device support, the rear legs for compact folding.

AI summary
A folding stand for use with a mobile device comprises a front pair of legs being spaced-apart from one another defining a gap, and having a front foot at the bottom end interconnecting the front pair of legs. A rear leg pivotally coupled to the front pair of legs. The front pair of legs and the rear leg having at least two positions with respect to one another, including: 1) a collapsed retracted position in which the rear leg is folded between the front pair of legs, and with the mobile device removed from the front foot; and 2) an expanded extended position in which the rear leg is unfolded from between the front pair of legs with bottom ends of the front and rear pairs of legs configured to be disposed on a support surface, and configured to receive the mobile device disposed on the front foot and leaning against the front pair of legs.
