Notebook Hinge Lift Structure for Air Outlet Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing notebook computer configurations face challenges in balancing heat dissipation and product appearance, with one configuration obstructing airflow due to a gap affecting overall appearance, while the other may cause screen temperature rise due to blocked airflow.
Innovation Solution
An electronic device with a rotating-axle apparatus that connects two main bodies, allowing the second main body to ascend relative to the first during rotation, exposing an air outlet and ensuring unobstructed airflow for heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the rotation center is configured above the upper surface of the keyboard housing, then heat dissipation is improved, but the upper housing must have a gap which affects product appearance
Solution Approach 1:
The patent applies the dynamics principle by making the rotation center position changeable rather than fixed. The rotating-axle apparatus enables the rotation center to dynamically move between two positions: above the upper surface when opened (for heat dissipation) and below the upper surface when closed (for appearance). This dynamic repositioning resolves the contradiction by allowing the system to optimize for different requirements at different operational states.
2Shape
If the rotation center is configured below the upper surface of the keyboard housing, then product appearance is improved, but airflow is blocked causing screen temperature to rise
Solution Approach 1:
The patent applies the dynamics principle by making the rotation center position changeable rather than fixed. The rotating-axle apparatus enables the rotation center to dynamically move between two positions: above the upper surface when opened (for heat dissipation) and below the upper surface when closed (for appearance). This dynamic repositioning resolves the contradiction by allowing the system to optimize for different requirements at different operational states.
3Temperature
If the second main body moves above the first main body during rotation, then airflow is unobstructed for heat dissipation, but the rotating-axle apparatus becomes more complex
Solution Approach 1:
The patent applies the merging principle by integrating multiple functions into the rotating-axle apparatus. The apparatus simultaneously achieves: (1) enabling the rotation center to reposition vertically, (2) allowing the second main body to move above the first main body, and (3) maintaining structural integrity. By combining these functions into a single integrated mechanism rather than separate components, the patent reduces overall system complexity while achieving the desired heat dissipation effect.

AI summary
An electronic device and a state switching method are provided in the present disclosure. The electronic device includes a first main body, a second main body, and a rotating-axle apparatus, where the rotating-axle apparatus connects the first main body with the second main body to make the second main body at an open state or a closed state relative to the first main body; and an air outlet is disposed on a side of the first main body. The rotating-axle apparatus is configured to, in a process of rotating the second main body around a rotation center to the open state, drive the second main body to ascend along a first direction relative to the first main body and move above the first main body to expose the air outlet.
