Laptop Display Gear Rack Stylus Extraction Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laptop computers face challenges in heat dissipation due to blocked cooling vents when the display is unfolded, and they also struggle with easy removal of the stylus pen due to small hole dimensions.
Innovation Solution
The laptop computer design incorporates a gear set and rack structure that allows the display unit to unfold without blocking the cooling vents, while also featuring a movable frame and connecting member that enables easy extraction of the stylus pen by sliding along a slope surface or with the aid of a resilient member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is unfolded relative to the main body, then the display can be used for computing operations, but the cooling vents on the rear side of the main body are blocked and heat dissipation performance is reduced
Solution Approach 1:
The patent applies the dynamics principle by making the connecting member movable between a first position (when display is folded) and a second position (when display is unfolded). This dynamic adjustment allows the connecting member to automatically clear the cooling vents when the display is unfolded, resolving the contradiction between display usability and heat dissipation performance.
2Adaptability or versatility
If a hole is formed on the lateral side of the display to receive the stylus pen, then the stylus pen can be stored, but the small dimensions of the hole make it difficult to take out the stylus pen
Solution Approach 1:
The patent applies the dynamics principle by making the frame movable between a retracted position (when display is folded) and an extended position (when display is unfolded). This dynamic movement allows the stylus pen to be easily accessed by sliding the frame along the slope surface, resolving the contradiction between stylus pen storage and ease of removal.
Solution Approach 2:
The patent applies the dimensionality change principle by introducing a slope surface that guides the frame's movement in a specific direction. This dimensional guidance facilitates easy stylus pen removal by providing a mechanical advantage through the inclined plane, transforming the difficult vertical extraction into an easier sliding motion.
3Adaptability or versatility
If the connecting member is designed to allow display unfolding, then display mobility is achieved, but the structure becomes complex with multiple components
Solution Approach 1:
The patent applies the merging principle by integrating multiple functions into the connecting member: it serves as both the display connector and the cooling vent clearance mechanism. By combining these functions into a single movable component, the patent reduces overall structural complexity while achieving the desired display mobility and heat dissipation.
Solution Approach 2:
The patent applies the universality principle by designing the connecting member to perform multiple functions: connecting the display to the main body, enabling display unfolding, and clearing cooling vents. This multi-functional design reduces the number of separate components needed, thereby simplifying the overall structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances heat dissipation by preventing the display from blocking the cooling vents and simplifies the process of removing the stylus pen, improving user convenience and device performance.
Implementation Method 1
The gear set is connected between the main body and the rack structure, wherein when the display unit is unfolded relative to the main body, the gear set impels the connecting member, the movable member, and the frame in a first direction via the rack structure
Implementation Method 2
The rack structure is disposed on the connecting member
Implementation Method 3
the housing forms a slope surface, and when the display unit is unfolded relative to the main body, the frame slides out of the movable member along the slope surface
Implementation Method 4
the laptop computer further includes a resilient member connected between the frame and the housing

AI summary
A laptop computer is provided, including a main body and a display unit pivotally connected to each other. When the display unit is unfolded relative to the main body, a gear set inside the display unit rotates and drives a frame to move via a rack structure. Thus, the frame and a stylus pen in the frame move out of an opening in the front cover of the display unit so that the user can take out the stylus pen easily.
