Cam-Guided Hinge With Movable Rotating Axle for Device Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinges with fixed rotating axles in electronic devices cause interference and hinder heat dissipation due to lack of clearance between device parts during opening.
Innovation Solution
A hinge design featuring a movable rotating axle with a cam piece and linkage mechanism that creates a height difference between device parts, allowing for increased clearance and facilitating heat dissipation through movable slots and protrusions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a fixed rotating axle is used to connect device parts, then the structure is simple and stable, but clearance between device parts is insufficient and heat dissipation is hindered
Solution Approach 1:
The rotating axle is transformed from a fixed position to a movable one, allowing it to dynamically adjust its position along the cam groove during rotation. This dynamic adjustment creates variable clearance between device parts, improving heat dissipation while maintaining structural compactness
Solution Approach 2:
The cam mechanism acts as an intermediary between the rotating axle and the base seat, converting rotational motion into axial displacement of the rotating axle. This intermediary mechanism enables clearance adjustment without directly complicating the overall hinge structure
2Length of stationary object
If a movable rotating axle with cam mechanism is used, then clearance and heat dissipation are improved, but the hinge structure becomes more complex
Solution Approach 1:
The cam mechanism is integrated directly into the base seat structure, with the cam groove formed as part of the base seat rather than as a separate component. The rotating axle combines rotational and translational degrees of freedom in a single element, reducing the number of separate parts while achieving clearance adjustment
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 design prevents interference during device rotation and enhances heat dissipation by increasing clearance, enabling smoother operation and improved thermal management.
Implementation Method 1
a cam piece which is securely mounted on the rotating axle. The cam piece has a cam surrounding portion which is securely sleeved on the rotating axle, and a first protrusion which projects radially from the cam surrounding portion and which is movably disposed in the first slot portion
Implementation Method 2
a linkage which is pivotally connected between the base plate and the rotating axle

AI summary
A hinge connectable between a first device part and a second device part includes a base seat unit and a rotating unit. The base seat unit includes first and second base seat for connecting with the first and second device parts. A base plate of the first base seat is formed with a moving slot having a first slot portion and a second slot portion. The rotating unit includes a rotating axle movably extending through the moving slot and rotated with the second base seat, a linkage pivotally connected between the base plate and the rotating axle, and a cam piece rotated with the rotating axle. During rotation of the rotating axle and the cam piece with the second base seat, a first protrusion of the cam piece is moved along a lower edge of the first slot portion to bring the rotating axle into an upward movement.
