Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional hinge structure is used, then the device can be folded or unfolded, but it cannot maintain a stable angle during the folding or unfolding process
Solution Approach 1:
The hinge mechanism transitions from a static single-axis rotation to a dynamic multi-axis rotation system. The first and second hinge barrels rotate around different rotation axes respectively, allowing the display device to dynamically adjust and maintain various angles during folding and unfolding operations, thereby achieving both angle stability and operational flexibility
Solution Approach 2:
The hinge is divided into multiple independent rotational components: a first hinge barrel providing rotation around a first rotation axis, and a second hinge barrel providing rotation around a second rotation axis. This segmentation allows each component to contribute to angle control independently, enabling stable angle maintenance while improving folding control
2Adaptability or versatility
If a single rotation axis hinge is used, then the structure is simple, but the device cannot stop at certain angles during folding or unfolding
Solution Approach 1:
The hinge mechanism transitions from a static single-axis rotation to a dynamic multi-axis rotation system. The first and second hinge barrels rotate around different rotation axes respectively, allowing the display device to dynamically adjust and maintain various angles during folding and unfolding operations, thereby achieving both angle stability and operational flexibility
Solution Approach 2:
The hinge mechanism serves multiple functions: it enables folding and unfolding motion, provides angle stabilization during the process, and allows the device to stop at specific angles. The multi-axis rotation capability makes the hinge universally applicable to various folding configurations without requiring additional separate mechanisms
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 device can maintain a stable angle during folding or unfolding, enhancing flexibility and usability in mobile electronic devices.
Implementation Method 1
the first hinge barrel and the first hinge pin may be made of a metal material, and the surfaces of the first hinge barrel and the first hinge pin may be heat-treated to improve the hardness and wear resistance. The predetermined torque may be a friction torque produced by the friction force between the first hinge pin and the first hinge barrel

AI summary
A display device includes: a display module including a first surface which displays an image and a second surface opposite to the first surface; a hinge disposed on the second surface of the display module; and a pair of supporting members connected to sides of the hinge and rotatable with respect to a pair of first rotation axes, respectively. The hinge includes: a base frame; a pair of hinge pins coupled to the base frame and providing a pair of second rotation axes, respectively, which are different from the pair of first rotation axes; and a pair of hinge barrels rotatably coupled to the pair of hinge pins, respectively.
