Lifting Mechanism for Slim Portable Device Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Slim notebook computers face stability issues when the display module pivots due to the small thickness of the host module, causing the display to hit supporting surfaces, and existing solutions either increase thickness, alter appearance, or risk damage.
Innovation Solution
A portable electronic device with a lifting mechanism comprising a base, linking component, sliding component, and pushing component that allows the host module to lift as the display module pivots, preventing the display from hitting surfaces without modifying thickness or appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a pad is disposed on the bottom of the host module to raise the rear side, then the host module can be stabilized on the supporting plane, but the thickness of the host module increases and the appearance is affected
Solution Approach 1:
The patent employs a dynamic lifting mechanism that activates only when the display module pivots to a predetermined angle. The lifting component rises to provide stability, and retracts when not needed, making the thickness increase conditional rather than permanent. This resolves the contradiction by making the stability enhancement dynamic rather than static.
Solution Approach 2:
The lifting mechanism proactively prevents the host module from contacting the supporting plane by detecting the pivoting angle and activating before contact occurs. This preliminary action eliminates the need for a permanent pad, as the lifting component intervenes just in time to prevent instability.
2Stability of the object's composition
If the end edge of the display module is designed as a pad for supporting, then the display module can be stabilized, but the host module may be pressed and broken and the end edge of the display module is damaged
Solution Approach 1:
The lifting component serves as an intermediary between the host module and the supporting plane. Instead of the display module end edge directly contacting and potentially damaging the host module, the lifting component mediates the contact, distributing forces safely and preventing direct pressure on fragile components.
3Object-affected harmful factors
If the maximum angle between the display module and the host module is limited, then the display module will not hit the supporting plane, but the user experience is affected
Solution Approach 1:
The lifting mechanism dynamically adjusts the host module's position based on the display module's pivoting angle. When the angle increases, the lifting component activates to maintain stability, allowing the user to achieve larger angles without hitting the supporting plane. This preserves user experience by enabling full range of motion while preventing damage.

AI summary
A portable electronic device includes a host module, a display module pivoted to the host module, a pivoting component and a lifting mechanism. The pivoting component is driven by the display module to rotate simultaneously. The lifting mechanism includes a base, a linking component connected to the base, a sliding component and a pushing component. A guiding slot is formed on the sliding component, and the guiding slot sheathes the linking component. The pushing component is installed on the pivoting component for pushing the sliding component to move in a first direction after the display module pivots relative to the host module to a predetermined angle, so that the guiding slot guides the linking component to move in a second direction different from the first direction, so as to drive the base to protrude outside a bottom side of the host module to lift the host module up.
