Hinge Elastic Member One-Hand Stand Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices require two hands and multiple steps to adjust a stand to a desired angle, making it inconvenient for users.
Innovation Solution
A hinge system utilizing an elastic member, such as a torsion spring, to rotate links and form a desired angle between a stand and a housing, allowing a user to operate the device with one hand by forming a seamless structure between the stand and the main body through sliding members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional stand structure is used, then the stand can be rotated to a predetermined angle, but two hands and multiple steps are required to complete the operation
Solution Approach 1:
The elastic member (torsion spring) is configured to automatically rotate the stand to the predetermined angle when the stand is released by the user. The elastic member stores energy when the stand is in the initial position and releases this energy to rotate the stand to the desired angle, eliminating the need for manual rotation and reducing the operation to a single step of releasing the stand
Solution Approach 2:
The elastic member is pre-configured and pre-loaded between the first link and the second link to provide the rotational force needed to position the stand at the predetermined angle. This preliminary setup of the elastic mechanism allows the stand to self-adjust without requiring the user to perform the rotation action
2Adaptability or versatility
If a conventional stand structure is used, then the stand can support the tablet, but the structure requires separate components for support and angle adjustment
Solution Approach 1:
The hinge mechanism integrates multiple functions into a single unified structure. The first link, second link, and elastic member work together to simultaneously provide stand support, angle adjustment, and automatic positioning functions. The elastic member serves both as a mechanical connector and as the actuating mechanism for angle adjustment, merging support and adjustment functions into one integrated system
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
Enables the stand to be rotated to a predetermined angle with one hand in a single step, enhancing user convenience and facilitating operations like viewing or touching the device's display.
Implementation Method 1
The elastic member is disposed between the second link and the third link. The elastic member is propped against the second link and the third link.
Implementation Method 2
the elastic member is a torsion spring and disposed in a position where the second link is pivoted to the third link, and the torsion spring includes two ends propped against the second link and the third link respectively
