Laptop Hinge Mechanism with Pivoting Protection Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laptop computers face challenges in heat dissipation efficiency due to their thinning design, which limits the space and size of heat dissipation structures and fans, necessitating an improved design to enhance thermal management.
Innovation Solution
The integration of a hinge mechanism that allows the display to rotate relative to the host, incorporating a protection cover that pivots and inclines, exposing the housing opening for improved heat dissipation and enabling the placement of electronic devices on the protection cover for additional functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the laptop computer is designed to be thinner, then the portability is improved, but the heat dissipation efficiency deteriorates due to limited space for heat dissipation structures and fans
Solution Approach 1:
The patent utilizes the third dimension by designing a movable protection cover that can pivot between a first position (covering the opening) and a second position (exposing the opening). This dynamic spatial arrangement allows the system to switch between different functional states without increasing the laptop's thickness, thereby resolving the contradiction between thin design and heat dissipation capability.
2Adaptability or versatility
If the display is made rotatable via hinge mechanism, then the viewing flexibility is improved, but the structural complexity increases
Solution Approach 1:
The patent combines the protection cover mechanism with the hinge mechanism, so that a single rotational movement simultaneously achieves two functions: protecting the screen when closed and enabling heat dissipation when open. This integration reduces the need for separate mechanisms and simplifies the overall structure while maintaining viewing flexibility.
3Temperature
If the protection cover is made movable to expose opening for heat dissipation, then the heat dissipation efficiency is improved, but the reliability of protection deteriorates
Solution Approach 1:
The patent employs a dynamic protection cover that can change its position between a first position (providing protection) and a second position (enabling heat dissipation). This dynamic design allows the system to adapt to different operational requirements, providing both protection and heat dissipation functionality as needed, thereby resolving the contradiction between protection reliability and heat dissipation efficiency.

AI summary
A laptop computer includes a host, a hinge mechanism, and a display. The host includes a housing, a pivoting base, and a protection cover that pivots on the pivoting base. The hinge mechanism is connected to the host, and includes a first shaft disposed in the housing, and a connection element connected to the first shaft. The display is connected to the hinge mechanism. When the display is rotated about the host, the connection element is rotated following the first shaft and makes the protection cover rotating relative to the housing.
