Retractable Heat Dissipating Stand for Portable Computers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable computers face challenges in balancing heat dissipation efficiency, ergonomic design, and aesthetic appearance, as foot cushions increase thickness when not in use and do not provide a carrying function.
Innovation Solution
A portable computer with a heat dissipating stand that slides into a U-shaped slot, featuring arc-shaped fixing ends and a wave-shaped foot base, allowing for rotation to serve as a handle and adjust angle for improved ergonomics and heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If foot cushions are disposed on the bottom of the host module to enlarge the gap and enhance convection effect, then heat dissipating efficiency is improved, but the thickness of the portable computer increases when not in use, affecting aesthetic feeling
Solution Approach 1:
The foot cushion is designed as a movable component that can rotate between a first position (protruding from the bottom surface) and a second position (retracted into the housing). When in use, it protrudes to enhance heat dissipation by enlarging the gap between the host module and supporting surface. When not in use, it rotates to the retracted position, maintaining a sleek appearance without increasing overall thickness.
Solution Approach 2:
The foot cushion is separated from the main housing structure as an independent rotatable component. This segmentation allows it to perform its heat dissipation function when needed while being storable when not in use, resolving the contradiction between functional requirement and aesthetic requirement.
2Ease of operation
If foot cushions are used to lift the keyboard mechanism and display module for ergonomic comfort, then user comfort is improved, but the structure complexity increases
Solution Approach 1:
The foot cushion serves multiple functions: (1) it acts as a spacer to enlarge the gap for heat dissipation, (2) it functions as a lifting mechanism to adjust the angle of the keyboard and display module for ergonomic comfort, and (3) it can be rotated to serve as a carrying handle. This multi-functionality reduces the need for separate components, thereby simplifying the overall structure while achieving ergonomic benefits.
3Temperature
If the foot cushion is designed to protrude from the bottom surface for heat dissipation, then convection effect is enhanced, but the occupied space increases when not in use
Solution Approach 1:
The foot cushion is designed with rotational capability, allowing it to dynamically change its position. When heat dissipation is needed, it rotates to the protruding position to maximize the gap and enhance convection. When not in use, it rotates to the retracted position, minimizing the occupied space and maintaining a compact form factor.

AI summary
A portable computer includes a host module having a host housing. A slot is formed on the host housing, and the slot includes a first fixing end and a second fixing end. The portable computer further includes a display module pivoted to the host module, and a heat dissipating stand installed inside the slot on the host housing in a slidable manner. When an end of the heat dissipating stand is fixed on the first fixing end of the slot, the heat dissipating stand is contained inside the slot completely. When the end of the heat dissipating stand is fixed on the second fixing end of the slot, the other end of the heat dissipating stand protrudes out of the slot and is disposed under the host housing so as to lift the host module.
