Multi-Hinge Stand Structure for Stable Vertical Device Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stand devices are unable to stably support electronic apparatuses with flexible displays in both horizontal and vertical postures, as they are designed primarily for horizontal orientations and struggle with the unique chassis dimensions of such devices.
Innovation Solution
A stand device with a base block and multiple rotatable stand plates connected by hinge devices, allowing for adjustable support in both horizontal and vertical orientations through a combination of hinge devices with torque generators to maintain stability and angular positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional stand device is used, then the electronic apparatus can be supported in horizontal posture, but it cannot stably support the electronic apparatus in vertical posture
Solution Approach 1:
The stand device is divided into multiple independent stand plates (first stand plate, second stand plate, third stand plate) that can be independently positioned and adjusted. Each stand plate can be rotated relative to the base block and to each other, allowing the device to adapt to different support postures (horizontal, vertical, and intermediate angles) while maintaining stability through distributed weight bearing across multiple contact points.
2Adaptability or versatility
If the stand device uses multiple rotatable stand plates with hinge devices, then it can support both horizontal and vertical postures, but the device complexity increases
Solution Approach 1:
Multiple hinge devices (first hinge device, second hinge device, third hinge device, fourth hinge device) are combined into a unified rotational mechanism system. The hinge devices share common rotation axes that are collinear, allowing the stand plates to be rotated and positioned independently while being part of an integrated structure. This merging approach reduces the number of separate components needed compared to having completely independent mounting mechanisms for each stand plate.
Solution Approach 2:
The base block serves multiple functions: it provides the mounting surface for all hinge devices, acts as the primary support structure, and serves as the reference frame for all rotational movements. The hinge devices are designed with universal rotation axes that can accommodate different stand plate configurations, allowing the same mechanical structure to support various postures without requiring posture-specific components.

AI summary
A stand device includes a base block, a first stand plate, a second stand plate, a third stand plate, a first hinge device that connects the first stand plate to the base block, a second hinge device that connects the first stand plate and the second stand plate, a third hinge device that connects the second stand plate and the third stand plate, and a fourth hinge device that connects the third stand plate to the base block. The stand device is configured so that the rotation axis of the third hinge device is located on an extension of the rotation axis of the first hinge device and the rotation axis of the fourth hinge device is located on an extension of the rotation axis of the second hinge device.
