Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with touch display screens experience wobbling when operated, leading to visual discomfort and difficulty in use due to the prolonged duration of wobbling, which is not effectively addressed by existing hinge structures.
Innovation Solution
A hinge structure comprising a first and second bracket pivoted through a hinge, with a third bracket having a rotatable connecting portion that generates kinetic friction upon relative rotation, effectively acting as a friction damper to consume wobbling kinetic energy and reduce the duration of wobbling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional hinge structure is used to pivot the display screen and main unit, then the device achieves portability and ease of operation, but the display screen experiences prolonged wobbling when touched, causing visual discomfort and operational difficulty
Solution Approach 1:
The patent converts the harmful wobbling motion into beneficial kinetic friction by designing a friction damper mechanism. The third bracket with rotatable connecting portion generates kinetic friction against the inner wall of the hollow column, transforming the unwanted wobbling energy into frictional heat, thereby rapidly damping the oscillation and stabilizing the display screen.
Solution Approach 2:
The patent changes the physical parameters of the hinge system by introducing a friction-based damping mechanism. The kinetic friction between the pillar and hollow column inner wall provides a damping force that changes with the velocity of wobbling, dynamically adjusting the system's energy dissipation characteristics to reduce wobbling duration.
2Duration of action of moving object
If the hinge structure allows free rotation between brackets for portability, then the device can be easily opened and closed, but the lack of damping mechanism causes extended wobbling when the display screen is touched
Solution Approach 1:
The patent segments the hinge structure into distinct functional components: the first and second brackets for pivoting, and the third bracket with connecting portions for damping. This segmentation allows the hinge to simultaneously provide rotation functionality and vibration damping without compromising either function.
Solution Approach 2:
The third bracket acts as an intermediary element between the first and second brackets. It introduces the friction damping mechanism as a mediator that dissipates wobbling energy while allowing the primary pivoting function to continue uninterrupted, thus reducing wobbling duration without blocking the rotational motion.
3Stability of the object's composition
If a friction damper mechanism is added to reduce wobbling, then the kinetic energy of wobbling is consumed through kinetic friction, but the hinge structure becomes more complex with additional connecting portions
Solution Approach 1:
The patent merges the damping function with the existing hinge structure by integrating the third bracket into the pivotal connection system. The friction damper mechanism is combined with the rotating connection, allowing both pivoting and damping functions to be achieved within a unified structural framework rather than as separate added components.
Solution Approach 2:
The third bracket with rotatable connecting portion serves multiple functions: it maintains the structural integrity of the hinge while simultaneously providing vibration damping through kinetic friction. This multi-functional design reduces wobbling without requiring entirely separate damping components, thereby limiting the increase in overall structural complexity.
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 structure significantly reduces the duration of wobbling, allowing the device to come to a standstill faster, thereby eliminating user discomfort and enhancing operational smoothness.
Implementation Method 1
the second connecting portion is adapted to rotate relatively to the first connecting portion to a limited extent, so that a wobbling kinetic energy of the third bracket is consumed by a kinetic friction of relative rotation between the first connecting portion and the second connecting portion

AI summary
A hinge structure includes a hinge, a first bracket, a second bracket and a third bracket. The first bracket and the second bracket are pivoted with each other through the hinge, wherein the second bracket has a first connecting portion. The third bracket has a second connecting portion, wherein the second connecting portion is rotatably connected to the first connecting portion. When the third bracket receives a force and wobbles, the second connecting portion rotates relatively to the first connecting portion, and a kinetic energy of the third bracket is consumed by a kinetic friction between the first connecting portion and the second connecting portion. In addition, an electronic device having the hinge structure is also provided.
