Solution Overview
Problem
Portable notebook computers face challenges in heat dissipation due to their compact size, which limits the accommodation of additional heat dissipation elements, leading to increased temperatures and reduced performance, necessitating higher energy consumption and increased fan noise.
Innovation Solution
The design includes a pivotally connected screen module and input/output module with an actuating element that lifts the input/output module away from the main body when opened, creating a gap for improved air flow and heat dissipation, utilizing cooling holes and potentially a cooling fan to enhance heat dissipation performance even when the device is on a flat surface.

Engineering Contradiction Analysis
1Weight of moving object
If the notebook computer size is decreased to make it more portable, then the portability is improved, but the heat dissipation capacity is reduced
Solution Approach 1:
The patent utilizes the third dimension by lifting the input/output module vertically away from the main body module, creating a gap that enables heat dissipation in a new spatial dimension. This vertical movement transforms the two-dimensional heat dissipation surface into a three-dimensional heat dissipation volume, allowing hot air to escape more effectively without increasing the device's footprint.
Solution Approach 2:
The input/output module is separated from the main body module through the lifting mechanism, creating distinct functional zones. This segmentation allows the space between modules to be utilized for heat dissipation purposes, with the gap serving as a dedicated heat escape channel independent of the main body's heat dissipation surfaces.
2Temperature
If a high-speed fan is used to maintain heat dissipation capacity, then the heat dissipation performance is improved, but the power consumption and noise increase
Solution Approach 1:
The lifting mechanism enables the device to create its own heat dissipation pathways using natural convection currents. The gap between modules allows hot air to rise and escape passively, utilizing the natural buoyancy of heated air rather than requiring active mechanical forcing, thereby reducing dependence on high-power cooling fans.
Solution Approach 2:
The input/output module transitions from a static position to a dynamic lifted position, changing the heat dissipation configuration based on operational needs. When the screen is opened, the input/output module automatically lifts to create optimal heat dissipation gaps, dynamically adapting the thermal management system to the device's operational state.
3Device complexity
If the input/output module remains abutting against the main body module, then the device structure is simple, but the heat dissipation is blocked
Solution Approach 1:
The solution moves the input/output module from a two-dimensional planar contact with the main body to a three-dimensional elevated position, creating a vertical gap. This dimensional change transforms the heat dissipation pathway from a blocked two-dimensional surface to an open three-dimensional channel, allowing heat to escape through the newly created vertical space.
Solution Approach 2:
The lifting mechanism acts as an intermediary element that mediates between the input/output module and the main body module. By introducing this mechanical intermediary, the system achieves both thermal separation and structural coherence, with the lifting mechanism serving as the mediating structure that enables heat dissipation while maintaining overall device integration.

AI summary
A portable electronic device includes a screen module, a main body module and an input/output module. The screen module is pivotally connected with the body module. The input/output module is electrically connected with the main body module. An actuating element is disposed at a bottom of the screen module. When the screen module is opened respectively to the body module to be opened, the actuating element is driven to swing to push a front end of the input/output module to be lifted to drive the input/output module to be out of a state that the keyboard abuts against the main body module. Therefore, the portable electronic device is easy to be operated. Moreover, the heat dissipation is improved to keep the internal temperature low and reduce energy consumption.
