Mobile Device Stand with Sliding and Pivot Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile device stands are bulky, prevent wireless charging, and require two hands to deploy, making them inconvenient for use with modern smartphones and tablets that have smooth surfaces and larger screens.
Innovation Solution
A mobile device stand that moves between a flat and deployed position, featuring a back plate with parallel tracks, a sliding plate, and a pivot plate, allowing one-handed deployment and enabling wireless charging, with a design that does not obstruct camera or fingerprint sensors, and can be adjusted for optimal placement based on device features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional mobile device stand is used, then the device can be held securely, but the stand is bulky and prevents wireless charging
Solution Approach 1:
The stand is divided into multiple functional components: a back plate with adhesive for mounting, a sliding plate with finger engagement features, and a pivot plate with viewing angle adjustment capability. This segmentation allows each component to be optimized for its specific function while maintaining overall compactness
Solution Approach 2:
The stand components are designed to nest within each other when not in use. The sliding plate and pivot plate can be positioned within the contours of the back plate, creating a compact profile that does not interfere with wireless charging coils
2Reliability
If a conventional mobile device stand is used, then the device can be held securely, but it requires two hands to deploy
Solution Approach 1:
The stand incorporates self-aligning features where the sliding plate automatically engages with the back plate tracks, and the pivot plate self-locks at desired viewing angles. This self-service mechanism eliminates the need for complex manual assembly or adjustment
Solution Approach 2:
The sliding plate acts as an intermediary between the user's finger and the pivot plate mechanism. By engaging the sliding plate's finger engagement features, the user can easily manipulate the stand's deployment without directly handling the smaller, more complex pivot mechanism
3Reliability
If a conventional mobile device stand is used, then the device can be held securely, but it obstructs camera or fingerprint sensors
Solution Approach 1:
The back plate is designed with locally optimized features including adhesive regions positioned away from sensor areas, and mounting holes strategically placed to avoid obstructing cameras or fingerprint sensors. This local quality approach allows the stand to be securely mounted while preserving sensor functionality
4Shape
If a mobile device stand with smooth surface materials is used, then the device looks aesthetically pleasing, but it is harder to manipulate with one hand
Solution Approach 1:
The stand creates an asymmetric grip configuration where the sliding plate and pivot plate form an irregular shape that naturally fits the contours of a human hand. This asymmetric design provides multiple finger engagement points that are strategically positioned for one-handed manipulation while maintaining aesthetic appearance

AI summary
A stand for a mobile device. The stand includes a back plate having a pair of parallel tracks, the back surface of the back plate attached to a back surface of the mobile device. The stand includes a sliding plate having a first end coupled to the back plate and configured to slide along the pair of parallel tracks. The stand includes a pivot plate having a first end connected to the second end of the sliding plate at a hinge, a second end connected to the back plate, and the pivot plate is configured to pivot relative to the back plate when the first end of the sliding plate slides along the pair of parallel tracks. The pivot plate, the sliding plate, and the back plate form one or more channels for receiving one or more fingers of a user when the stand is in the deployed position.
