Pivot Device Translating Screen for Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook computer designs with pivotably connected screens and keyboards face issues with heat dissipation and key obstruction due to the screen's position, limiting the use of the keyboard's front edge for hot air outlets and key functionality.
Innovation Solution
A pivot device with a translating unit that includes a base and sliding components, allowing the screen to translate during rotation, thereby increasing the space for heat dissipation and accommodating additional features like buttons or devices behind the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the screen is pivotably connected to a position adjacent to the front edge of the keyboard to maximize screen proportion, then the screen area is improved, but the heat dissipation performance deteriorates due to limited space for hot air outlets
Solution Approach 1:
The patent applies the dynamics principle by making the screen's position relative to the keyboard adjustable through a translating mechanism. The screen can be moved forward or backward along the front edge of the keyboard, allowing dynamic optimization of both screen area and heat dissipation space depending on operational requirements. This resolves the contradiction by enabling the system to adapt its configuration rather than being fixed in a single position.
Solution Approach 2:
The patent introduces an additional degree of freedom by allowing the screen to translate not only pivot but also along the front edge of the keyboard. This dimensional change enables the screen to occupy different positions along the keyboard's length, creating space for heat dissipation outlets while maintaining large screen area, thus resolving the spatial conflict between screen size and thermal management.
2Area of moving object
If the screen is pivotably connected by a single hinge or dual hinges to maximize screen proportion, then the screen area is improved, but the keyboard functionality deteriorates due to blocked key area
Solution Approach 1:
The translating mechanism enables dynamic adjustment of the screen's position along the keyboard's front edge. When full keyboard functionality is needed, the screen can be positioned to clear the key area. When maximum screen proportion is prioritized, the screen can be positioned closer to the front edge. This dynamic repositioning resolves the contradiction between screen area and keyboard usability.
3Area of moving object
If the screen is positioned to maximize screen proportion, then the screen area is improved, but the versatility deteriorates due to inability to install additional features behind the screen
Solution Approach 1:
The adjustable translating mechanism allows the screen to be repositioned along the keyboard's front edge. This creates flexible space configuration that can accommodate different feature installations behind the screen position. When additional features are needed, the screen can be positioned to leave adequate space; when maximum screen area is needed, the screen moves forward. This resolves the contradiction between screen proportion and installation versatility.

AI summary
A pivot device invention includes a base and a translating unit. The base includes a side having first and second connecting portions. The translating unit includes a first sliding seat, a pivot, a first wheel, a second wheel, and a first interlink. The sliding seat is mounted to the first connecting portion and is movable relative to the base. The pivot and the second wheel are pivotably mounted to the sliding seat. The first wheel is mounted to and jointly rotatable with the pivot. Rotation of the first wheel is in an interlocking relationship with rotation of the second wheel. The first interlink is mounted to and jointly rotatable with the second wheel. The first interlink includes a first sliding portion mounted to the second connecting portion and movable relative to the base. Rotation of the first interlink actuates the sliding seat to move relative to the base.
