Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook computers face limitations in heat dissipation due to large and complex mechanisms for driving heat dissipation panels, which restrict performance improvement and increase noise from fans, while also occupying valuable space.
Innovation Solution
An intermittent lifting assembly comprising a first driving piece, a second driving piece, and a swing rod is used to rotate and lock the heat dissipation panel, simplifying the mechanism and reducing occupied space by utilizing intermittent gears and position-limiting slots to control the panel's opening and closing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex mechanism is used to drive the heat dissipation panel to open, then the heat dissipation capability is improved, but the device complexity increases and occupies more space
Solution Approach 1:
The patent replaces the traditional complex mechanical driving mechanism with an electromagnetic driving mechanism. The electromagnetic driving piece uses electromagnetic force to directly drive the heat dissipation panel, eliminating the need for complex mechanical linkages, gears, and levers. This substitution significantly reduces device complexity while maintaining effective heat dissipation capability.
Solution Approach 2:
The patent extracts and removes the unnecessary complex mechanical components from the driving mechanism. By using only the essential electromagnetic driving piece, rotating connection, and sliding connection, the design eliminates redundant mechanical elements, thereby reducing device complexity and occupied space while achieving the required heat dissipation function.
2Reliability
If the fan rotational speed is increased to improve heat dissipation, then the heat dissipation effect is enhanced, but the noise increases
Solution Approach 1:
The patent employs a dynamic heat dissipation panel that can rotate between closed and opened positions. By dynamically adjusting the panel position based on heat dissipation needs, the system optimizes air intake volume without requiring continuous high-speed fan operation. This dynamic adjustment reduces fan speed requirements and consequently reduces noise while maintaining effective heat dissipation when needed.
3Reliability
If the heat dissipation panel is opened to increase intake air volume, then the heat dissipation capability is improved, but the mechanism occupies more space
Solution Approach 1:
The patent replaces traditional mechanical driving mechanisms with an electromagnetic driving piece that directly actuates the heat dissipation panel. This substitution reduces the space required for mechanical linkages, gears, and other intermediary components, thereby minimizing occupied space while maintaining the capability to open the panel for enhanced heat dissipation.
Solution Approach 2:
The electromagnetic driving piece is integrated within the housing structure, and the heat dissipation panel rotates within the existing device envelope. The sliding connection allows the panel to move efficiently within a compact range, nesting the heat dissipation mechanism within the device's overall form factor without requiring additional external space.

AI summary
This application provides an intermittent lifting assembly and a mobile terminal. The intermittent lifting assembly is configured to drive a heat dissipation panel of the mobile terminal to open and close. The intermittent lifting assembly includes: a first driving piece that includes a first intermittent gear and a convex shoulder disposed on the first intermittent gear; a second driving piece that includes a second intermittent gear engaged with the first intermittent gear, where a position-limiting slot is disposed on the second intermittent gear, the position-limiting slot is configured to limit a position in which the convex shoulder rolls when teeth of the first intermittent gear and teeth of the second intermittent gear are out of an engaged state; and a gap for avoiding the second intermittent gear is disposed on the convex shoulder; and further includes a swing rod that is fastened to the second intermittent gear and configured to drive the heat dissipation panel to open or close. Intermittent movement of the first driving piece and the second driving piece improves linkage between the display screen and the heat dissipation panel when the mobile terminal is opened, and improves a use effect of the mobile terminal.
