Portable Terminal Hinge Stopper Mechanism for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable terminals are structurally unstable, making it inconvenient to watch broadcasting as users must hold the device to orient the screen, and existing solutions fail to ensure reliability and stability.
Innovation Solution
A portable terminal with a hinge stopper mechanism that includes a first and second hinge base and a hinge stopper, allowing the second housing to rotate about a hinge axis while the hinge stopper engages with the first hinge base to provide additional friction and stability, enabling the terminal to maintain a stationary state at various angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hinge device is used to rotatably couple housings for miniaturization and broadcasting function, then adaptability and broadcasting viewing convenience are improved, but structural stability and reliability deteriorate
Solution Approach 1:
A hinge stopper is introduced as an intermediary component between the first and second hinge bases. The stopper includes a stopper protrusion that engages with a stopper groove on the first hinge base, providing a mechanical constraint that mediates the rotational movement and prevents excessive rotation, thereby enhancing structural stability while maintaining the hinge's adaptability for broadcasting viewing
2Volume of moving object
If housings are rotatably coupled for folder-type or slide-type configuration, then miniaturization is achieved, but structural stability deteriorates
Solution Approach 1:
The hinge device is segmented into distinct components: a first hinge base, a second hinge base, and a separate hinge stopper. This segmentation allows each component to perform its specific function - the hinge bases provide rotational coupling for miniaturization while the stopper provides structural stabilization, resolving the contradiction between compact size and structural stability
3Ease of operation
If hinge bases rotate freely for viewing convenience, then ease of operation is improved, but structural stability worsens
Solution Approach 1:
The hinge stopper dynamically interacts with the rotating hinge bases - it allows free rotation during adjustment (maintaining ease of operation) but engages to provide mechanical stopping force when the stopper protrusion enters the stopper groove, creating stable stationary positions. This dynamic behavior resolves the contradiction between operational ease and positional stability
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
The hinge stopper mechanism enhances structural stability and reliability, allowing the terminal to be conveniently angled for broadcasting, improving user experience by maintaining a stable position without requiring manual holding.
Implementation Method 1
the hinge stopper is engaged with the first hinge base in at least one point while the second hinge base rotates, and thus stops rotation of the second hinge base

AI summary
A portable terminal is equipped with a first housing, a second housing and a hinge device, the second housing being coupled to one end of the first housing and rotating about a hinge axis extending in a longitudinal direction of the first housing, the hinge device rotatably coupling the first housing and the second housing, the hinge device including: a first hinge base mounted on the first housing or the second housing; a second hinge base mounted on the second housing or the first housing, coupled oppositely to the first hinge base, and rotating about the hinge axis; and a hinge stopper mounted adjacent to the second hinge base, and pivoting around the hinge axis as the second hinge base rotates, wherein the hinge stopper is engaged with the first hinge base in at least one point while the second hinge base rotates, and thus stops rotation of the second hinge base.
