Solution Overview
Problem
Existing portable computers, such as notebook PCs, face challenges in stabilizing the display at a tilted angle for touch operations due to torque-induced vibrations and the risk of the display toppling, and previous solutions are either not suitable for notebook PCs or are aesthetically and functionally cumbersome.
Innovation Solution
A portable computer design featuring a base with segmented areas, a display module with pivotally connected support elements, and a sliding assembly comprising a rod element and sleeve sliding element that allows the display to rotate and slide to a stable tilted angle, providing support and improved usability without complex linkage mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is opened to a suitable angle for touch operations, then the display can be positioned at a tilted angle for user operations, but the torque generated by applied force causes the display to vibrate back and forth
Solution Approach 1:
A support element is introduced as an intermediary component between the display and the base. This support element includes a first support portion connected to the display and a second support portion connected to the base, forming a mechanical bridge that stabilizes the display at the tilted angle and prevents vibration during touch operations.
Solution Approach 2:
The support element is designed with rotatable connections at both ends - the first end rotates relative to the display and the second end rotates relative to the base. This dynamic design allows the support element to adapt to angle changes while maintaining stability, enabling smooth transitions between different display angles without causing vibration.
2Ease of operation
If the user applies force on the display for touch operations, then touch functions can be performed, but the display could topple and fall backwards without proper support
Solution Approach 1:
The support element is installed in advance to provide preventive support before any topple can occur. By connecting the display to the base through this support structure, the system preemptively counteracts the risk of the display falling backwards when force is applied during touch operations.
Solution Approach 2:
The support element acts as a mediator that transfers and distributes the force applied to the display across a broader structural foundation. This intermediary structure prevents concentrated forces from causing the display to topple by distributing the load through the support portions connected to both the display and the base.
3Stability of the object's composition
If a support arm is added to support the display, then the display can be stabilized at a tilted angle, but the structure becomes more complicated with more components
Solution Approach 1:
The support element is segmented into two functional portions: a first support portion connected to the display and a second support portion connected to the base. This segmentation allows each portion to be optimized for its specific function while keeping the overall structure simple and avoiding the need for complex linkage mechanisms.
Solution Approach 2:
The invention extracts only the essential support function needed to stabilize the display, removing unnecessary complex linkage elements. By taking out just the critical support arm component with simple rotational joints, the solution achieves stability without the complexity of multiple interconnected mechanisms.
4Adaptability or versatility
If complex linkage mechanisms are used to support the display, then the display can be positioned at various angles, but the device becomes bulky and thick
Solution Approach 1:
The support element uses dynamic rotational joints at both ends instead of fixed rigid connections. This allows the display to be positioned at various angles through simple rotation of the support portions, eliminating the need for bulky multi-position adjustment mechanisms and reducing overall device thickness.
Solution Approach 2:
The invention extracts only the essential angle adjustment function through simple rotational joints, removing the need for complex linkage mechanisms and multiple support elements. This minimalistic approach achieves versatile angle adjustment while keeping the device compact and thin.
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
The design enables stable and convenient touch operations by allowing the display to be securely positioned at a tilted angle, reducing vibrations and the risk of damage, while maintaining a compact and aesthetically pleasing form factor.
Implementation Method 1
The first fixed end is pivotally connected to a portion of the display module other than the display face, such that the display module is able to rotate relative to the support element. The second fixed end is pivotally connected to the rear end or in proximity of the rear end of the base, such that the support element is able to rotate relative to the base.
Implementation Method 2
Each sliding assembly comprises a rod element and a sleeve sliding element sleeved onto the rod element. The rod element is at least disposed in the second area of the base, the sleeve sliding element is connected with the connecting end of the display module, and the sleeve sliding element can slide along the rod element.
