Movable Dust Cover Actuated by Display Rotation for Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices face challenges in heat dissipation due to compact designs, where heat-generated components occupy space needed for heat dissipation, leading to inefficiencies and potential component damage from overheating.
Innovation Solution
An electronic apparatus with a display component, base, and moveable case connected via a transmission component, where the display component's rotation actuates the moveable case to uncover or cover an opening, forming a heat dissipation channel between heat-dissipated modules and the environment, allowing for effective heat diffusion while protecting against dust.

If electronic components are assembled more compactly to pursue thinning tendency, then the device becomes thinner and lighter, but heat dissipation space is reduced and heat dissipation efficiency deteriorates
Solution Approach 1:
The dust cover is designed as a movable component that can rotate between a closed position (when display component is inserted) and an open position (when display component is removed). This dynamic structure allows the heat dissipation channel to be automatically activated only when needed, resolving the contradiction by maintaining device thinness while providing heat dissipation capability on demand.
Solution Approach 2:
The device is segmented into functional zones: the display component insertion region, the heat dissipation channel, and the dust cover mechanism. This segmentation allows the heat dissipation channel to be integrated within the limited space without interfering with other components, enabling effective heat dissipation in a compact design.

If additional space is allocated for heat dissipation component or channel, then heat dissipation efficiency improves, but device thickness increases
Solution Approach 1:
The dust cover serves multiple functions: it protects internal components from dust when the display component is inserted, and it acts as a movable component of the heat dissipation system when the display component is removed. This multi-functionality eliminates the need for separate dedicated heat dissipation components, maintaining device thinness while providing effective heat dissipation.
Solution Approach 2:
The heat dissipation channel is nested within the existing device structure, utilizing the space between the base and the dust cover. This nested arrangement allows the heat dissipation channel to be integrated without increasing device thickness, as it uses otherwise unused internal space.
3Temperature
If heat dissipation channel is created, then heat dissipation efficiency improves, but dust penetration risk increases
Solution Approach 1:
The dust cover is designed as a movable component that can rotate between a closed position (when display component is inserted) and an open position (when display component is removed). This dynamic structure allows the heat dissipation channel to be automatically activated only when needed, resolving the contradiction by maintaining device thinness while providing heat dissipation capability on demand.
Solution Approach 2:
The system provides automatic feedback-based control: when the display component is removed, the dust cover rotates to uncover the heat dissipation channel, enabling heat dissipation. When the display component is inserted, the dust cover automatically closes to protect against dust. This feedback mechanism resolves the contradiction by dynamically adjusting dust protection based on operational state.

AI summary
Electronic apparatus includes a display component, a base, a moveable case, and a transmission component. The display component includes a rotational shaft. The base is pivotally connected to the rotational shaft. The base has an opening. The moveable case is pivotally connected to the base. The moveable case can selectively cover or uncover the opening. The transmission component is disposed on the base. The transmission component is operatively connected between the rotational shaft and the moveable case. When the display component is rotated away from the base, the rotational shaft actuates the moveable case to rotate to uncover the opening through the transmission component. When the display component is rotated toward the base, the rotational shaft actuates the moveable case to rotate to cover the opening through the transmission component.
