Hidden Hinge Structure for Gap-Reducing Notebook Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing notebook computer designs feature a physical pivot structure that results in a gap between the display and system bodies when unfolded, compromising aesthetics due to the visible hinge mechanism.
Innovation Solution
A hidden hinge mechanism utilizing a first and second fixing assembly, rotating parts, bearing frames, and torque members that allow the hinge to pivot around a virtual axis, enabling the hinge to be concealed when the bodies are unfolded, reducing the gap between them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a physical pivot structure is used to connect the display body and system body, then the hinge can provide reliable rotation function, but a gap must be reserved between the display body and system body, resulting in poor aesthetics
Solution Approach 1:
The patent extracts the physical pivot from the visible area by placing it inside the display body. The rotation axis is positioned within the display body rather than at the edge, allowing the hinge mechanism to be hidden while maintaining the rotation function between the display body and system body.
Solution Approach 2:
The hinge mechanism is nested within the display body structure. The rotation axis and related components are contained inside the display body, with only the necessary connection points extending to the edge, allowing the system body to abut directly against the display body without visible gaps.
2Ease of operation
If a physical pivot is positioned at the edge to enable rotation, then the rotation function is achieved, but the hinge cannot be hidden and the gap remains visible
Solution Approach 1:
The patent extracts the visible portion of the hinge mechanism from the edge position and relocates it inside the display body. The rotation axis is positioned within the display body, allowing the system body to rotate relative to the display body without requiring a visible external pivot structure.
3Shape
If the display body and system body are positioned close together, then aesthetics are improved, but the physical pivot structure cannot be accommodated
Solution Approach 1:
The patent nests the rotation axis and hinge components inside the display body structure. This internal placement allows the system body to be positioned close to the display body without requiring external space for the pivot mechanism, eliminating the visible gap while maintaining rotation functionality.

AI summary
A hidden hinge includes a first fixing assembly, a second fixing assembly, a first rotating part and a second rotating part, a first bearing frame, a second bearing frame, and at least one torque member. The first rotating part and the second rotating part are rotatably disposed through the first fixing assembly and the second fixing assembly. The first rotating part and the second rotating part are parallel to each other and respectively have a first teeth portion and a second teeth portion. The first teeth portion and the second teeth portion are arranged in a vertically-staggered manner. The first bearing frame is slidably disposed on the first fixing assembly and has a first rack portion engaged with the first teeth portion. The second bearing frame is slidably disposed on the second fixing assembly and has a second rack portion engaged with the second teeth portion. The at least one torque member is sleeved around the first rotating part and the second rotating part.
