Pivotable Stand Plates for Portable Device Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable information devices with pivotable chasses face challenges in providing both convenience and a simple configuration when transitioning between closed and open states, due to the need for multiple folding lines to absorb surface differences, leading to a complex stand structure.
Innovation Solution
A portable information device with a stand device featuring pivotable first and second stand plates on the back faces of the chasses, which can switch between a connected and separated state, allowing for a flat-plate or stacked form, and utilizing magnetic attraction and lever mechanisms for secure positioning, enabling a simple and effective stand function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple folding lines are provided in the center of the stand plate to absorb circumferential difference between closed and open states, then the stand function can be provided, but the structure becomes complicated
Solution Approach 1:
The stand plate is divided into two separate stand plates (first stand plate and second stand plate) that can operate independently. Each stand plate is attached to a different chassis and can be folded separately, eliminating the need for multiple folding lines in a single integrated stand plate while maintaining adaptability to both closed and open states.
Solution Approach 2:
The stand plates are designed with dynamic characteristics, allowing them to be folded along with their respective chassis. The stand plates can transition between extended and folded positions dynamically, adapting to different device states without requiring a complex fixed structure with multiple folding lines.
2Reliability
If the stand plates are connected to move together, then the stand function is improved, but the configuration becomes more complex
Solution Approach 1:
The first and second stand plates are connected through connecting portions that allow them to move together when needed. This merging of functionality provides enhanced stand stability and reliability while maintaining a relatively simple configuration, as the connection mechanism is integrated into the existing hinge and stand plate structures rather than adding separate complex systems.

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 solution provides high convenience by allowing seamless transitions between forms while maintaining a simple configuration, ensuring the stand device securely holds the device upright without compromising the device's compactness or aesthetics.
Implementation Method 1
a magnet provided on the first stand plate; and an attracted object that is provided on the second stand plate and able to be attracted to the magnet

AI summary
A portable information device includes a first chassis, a second chassis adjacent to the first chassis and connected so as to be pivotable relative to the first chassis, and a stand device. The stand device includes a first and a second stand plate, which are provided on back faces of the first and the second chassis and movable between a housing position along the back face and an upright position in which the first and second stand plates protrudes from the back faces. The first stand plate and the second stand plate are switchable between a separated state, in which their adjacent ends are spaced apart from each other so as to be configured separately, and a connected state, in which their adjacent ends are connected to each other so as to move together between the housing position and the upright position.
