Moving Display Coupling Linkage for Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laptop designs face challenges in heat dissipation, leading to potential damage to the display due to heat-generating components, which increases the overall thickness and weight, compromising portability.
Innovation Solution
A portable computing device with a moving display that pivots to create a ventilation gap between the display and heat-generating components when open, while moving closer to the top shell when closed, reducing thickness and weight.

Engineering Contradiction Analysis
1Reliability
If heat insulation layer or reserve air gap is incorporated to protect display from heat, then display protection is improved, but overall thickness and weight increase
Solution Approach 1:
The patent applies the dynamics principle by making the air gap between the display and heat-generating components variable rather than fixed. The coupling linkage mechanism dynamically adjusts the distance between the display and top shell based on the lid position: when the lid is closed, the display is closer to the top shell (reducing thickness), and when the lid is opened, the display moves away to create a protective air gap. This dynamic adjustment resolves the contradiction between maintaining thin profile and providing heat protection.
2Reliability
If heat insulation layer or reserve air gap is incorporated to protect display from heat, then display protection is improved, but weight increases
Solution Approach 1:
The dynamics principle is applied to create a variable air gap that provides heat protection only when needed (during use with lid open), while maintaining a compact, lightweight structure when closed. The coupling linkage enables the display to move relative to the top shell, creating an air gap during operation without adding permanent insulating materials that would increase weight.
3Length of moving object
If display is kept close to top shell, then device thickness is reduced, but display is exposed to heat from components
Solution Approach 1:
The patent uses the dynamics principle to make the display position adjustable based on operational state. The coupling linkage mechanism automatically adjusts the display-to-top-shell distance: close when closed (reducing thickness) and far when open (reducing heat exposure). This dynamic positioning resolves the contradiction between thin profile and heat protection.
Solution Approach 2:
The coupling linkage mechanism provides self-service by automatically adjusting the display position based on the lid opening/closing action without requiring additional sensors or active control. The mechanical linkage itself senses the lid position and accordingly positions the display to either minimize thickness or maximize heat protection.

AI summary
In various examples, a portable computing device is provided that has a bottom shell and a top shell pivotally coupled to the bottom shell for movement between a closed position and at least one open position. A display fits within a perimeter rim of the top shell, the display being obscured from view when the top shell is in the closed position and being viewable when the top shell is in the at least one open position. A coupling linkage couples the display, the top shell, and the bottom shell, to move the display between at least a first position with the display closer to the top shell when the top shell is in the closed position and a second position with at least a portion of the display farther from the top shell when the top shell is in the open position.
