Curved Hinge Mechanism for Gap-Free Laptop Display Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laptop computers have a noticeable gap at the pivot point between the host and the display, affecting the appearance and user experience.
Innovation Solution
The integration of a hinge mechanism into the display and host, featuring a curved groove and rotation element, allowing the display to rotate along a curved path while applying torque, and incorporating a torque assembly and light source for improved aesthetics and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a conventional hinge mechanism is used to connect the display and host, then the display can be rotated relative to the host, but a noticeable gap appears at the pivot point affecting appearance
Solution Approach 1:
The patent applies curvature by designing the rotation element with a curved portion that fits into a curved groove on the base. This curved interface allows the display to rotate while maintaining continuous contact along the curved path, eliminating the gap at the pivot point and improving appearance without requiring complex additional components
2Shape
If the hinge mechanism is simplified to improve appearance, then the gap is reduced, but the torque application capability may be compromised
Solution Approach 1:
The patent merges the rotation and torque application functions into a single integrated hinge mechanism. The curved portion and curved groove provide both the rotational movement and the torque transmission path, while the torque assembly works in conjunction with this curved interface to apply torque between the display and host without requiring separate complex mechanisms
3Shape
If a curved groove and rotation element are used to eliminate the gap, then appearance is improved, but manufacturing precision requirements increase
Solution Approach 1:
The curved groove and curved portion are designed with complementary shapes that guide the rotation element along a defined curved path. This geometric design provides inherent alignment and self-centering during rotation, which helps maintain consistent appearance while managing manufacturing tolerances through the self-aligning nature of the curved interface
