Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Notebook computers with high operating performance tend to overheat when used on desktops or laps, leading to discomfort and potential damage to electronic elements.
Innovation Solution
An electronic device with a movable foot pad module that includes a first foot pad fixed to the body and a second foot pad rotatably connected through a rotating shaft, allowing the second foot pad to rotate 180 degrees to increase the space between the body and the platform for improved heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the notebook computer is placed on a desktop for use, then the device is stable and easy to operate, but the body may easily overheat due to insufficient heat dissipation space
Solution Approach 1:
The foot pad is designed to be movable rather than fixed, allowing it to rotate between a first state (coplanar with bottom surface) and a second state (rotated 180 degrees to protrude). This dynamic adjustment enables the device to switch between different heat dissipation configurations while maintaining operational stability.
Solution Approach 2:
The solution addresses the heat dissipation problem by utilizing the vertical dimension through rotation of the foot pad around an axis inclined relative to the bottom surface. By rotating the foot pad 180 degrees, the device raises itself to create additional space between the body and the desktop, effectively using dimensional change to improve thermal management.
2Temperature
If the notebook computer is placed on the user's lap for use, then the device is portable and convenient, but the body may cause discomfort or burn the user's thighs due to high temperature
Solution Approach 1:
The movable foot pad allows the user to dynamically adjust the device's configuration. When experiencing discomfort from heat, the user can rotate the foot pad to the second state, raising the device body to improve air circulation and heat dissipation, thereby reducing the harmful thermal effect on the user's thighs.
Solution Approach 2:
The foot pad rotation changes the spatial parameter (height/distance) between the device body and the supporting surface. By rotating the foot pad 180 degrees, the device body is raised, increasing the gap for heat dissipation and reducing the temperature transferred to the user's lap, thus changing the thermal parameter to improve comfort.
3Temperature
If the foot pad is made movable to increase heat dissipation space, then heat dissipation is improved, but the device complexity increases
Solution Approach 1:
The foot pad is segmented from the main device body, connected through a rotating shaft that allows independent movement. This segmentation enables the foot pad to rotate between two states while keeping the rest of the device structure simple and unchanged, minimizing the overall structural complexity.
Solution Approach 2:
Instead of adding complex active mechanisms (motors, sensors, controllers) to adjust the foot pad position, the invention uses a passive mechanical design where the foot pad can be manually rotated. This inverts the approach from active control to passive user-operated adjustment, significantly reducing device complexity while achieving the same heat dissipation function.

AI summary
An electronic device with movable foot pad, including a body and a foot pad module, is provided. The body has a bottom surface. The foot pad module includes a first foot pad, at least one second foot pad, and at least one rotating shaft connecting the first and second foot pads. The second foot pad is rotated relative to the first foot pad by the rotating shaft to switch the foot pad module between first and second states. An axial direction of the rotating shaft is inclined relative to the bottom surface. In the first state, the body is supported on the platform by the first and second foot pads. In the second state, the second foot pad is rotated 180 degrees relative to the first foot pad in the axial direction and protrudes from the first foot pad to support the body on the platform by the second foot pad.
