Portable Computer Keyboard Sliding Assembly for Tablet Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable computers with detachable display screens face complexity in assembly and operation due to intricate linkage mechanisms, which can be visually unattractive and pose risks of finger pinching, and require symmetric support to maintain smooth sliding, making them less user-friendly and prone to malfunction if asymmetry occurs.
Innovation Solution
A portable computer design featuring a detachable keyboard module with a pushing assembly and sliding assembly that allows the display module to rotate and slide relative to the base, using elastic elements to separate and combine keyboard portions, enabling 180-degree flipping and stable tablet mode conversion without complex symmetrical mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex linkage mechanisms are used to support and pivotally connect the display screen, then the display screen can rotate and transform relative to the computer body, but the structure becomes visually unattractive and exposes mechanisms that may pinch user's fingers
Solution Approach 1:
The patent extracts the harmful linkage mechanisms from the visible area by relocating them to the interior of the computer body. The sliding elements are positioned inside the computer body rather than externally, so that when the display screen rotates, the mechanisms are hidden within the structure, eliminating the finger pinching risk and improving visual appearance while maintaining the rotation capability
Solution Approach 2:
The patent implements nesting by placing the sliding elements and linkage mechanisms inside the computer body structure. The mechanisms are nested within the interior space, allowing the display screen to rotate and transform while the supporting structures remain concealed within the computer body, thus eliminating visual unattractiveness and safety hazards
2Stability of the object's composition
If sliding elements are confined at both sides of the keyboard module in a paired symmetrical structure, then the display screen can be moved in a balanced manner, but the structure becomes complex and requires complex linkage mechanisms for pivoting, linkage, and sliding
Solution Approach 1:
The patent extracts the sliding elements from the traditional paired symmetrical structure confined at both sides of the keyboard. Instead, the sliding elements are positioned inside the computer body, which simplifies the overall structure by eliminating the need for complex external linkage mechanisms while still achieving balanced movement through the internal arrangement
Solution Approach 2:
The patent changes the spatial arrangement by moving the sliding elements from a two-dimensional external symmetrical structure to a three-dimensional internal configuration within the computer body. This dimensional change allows the mechanisms to achieve balanced display screen movement while reducing structural complexity and eliminating the need for exposed linkage mechanisms
3Ease of operation
If supporting mechanisms are kept in a symmetric steady state, then smooth sliding can be maintained, but once one side is damaged, the display screen cannot be flipped successfully
Solution Approach 1:
The patent implements self-service through the elastic element that automatically adjusts and compensates for asymmetries or damage on one side. The elastic element provides self-balancing functionality, allowing the display screen to continue flipping and sliding even when one side is damaged, as the elastic element compensates for the imbalance without requiring manual intervention or perfect symmetry
4Ease of operation
If a detachable keyboard module with pushing assembly is used, then the display module can slide smoothly without interference from the keyboard, but additional components need to be provided to achieve the sliding and flipping effect
Solution Approach 1:
The patent merges the keyboard module with the sliding mechanism by integrating the pushing assembly into the keyboard structure. The keyboard module is designed with movable structures that can be pushed to create space for the display module to slide, combining the input function with the spatial adjustment function in a single integrated component, thus achieving smooth sliding without significantly increasing overall device complexity

Function Achieved in This Case
This design simplifies the assembly and operation by eliminating the need for complex linkage mechanisms, providing a stable and balanced sliding effect while avoiding finger pinching risks and ensuring smooth transitions between notebook and tablet modes, enhancing user safety and usability.
Implementation Method 1
Each moving structure comprises an elastic element and a pushing structure. The elastic element is connected to the base and the moving structure; the elastic element can push the moving structure to move towards a predetermined direction.

AI summary
A portable computer includes a base, a keyboard module, a pushing assembly, a display module, and a sliding assembly. The base includes a front end and a rear end. The keyboard module includes two keyboard portions; each keyboard portion is moveably combined with the base by at least one moving structure. The pushing assembly includes two pushing elements combined moveably with the base. The display module includes a connecting end and a support portion. The sliding assembly includes a slide corresponding element disposed in the base and a sliding element pivoted on the connecting end and moved along the slide corresponding element. When the connecting end moves towards the front end with the slide element, the pushing assembly pushes and moves the moving structures by the slide element, and the two keyboard portions are separated; then the connecting end is moved through the keyboard module with the slide element.
