Portable Computer Display Hinge for Landscape-Portrait Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Notebook computers with wide screens are limited in functionality as they are primarily designed for landscape mode, which is not ideal for tasks like browsing web pages or editing, and lack a mechanism to easily switch between modes.
Innovation Solution
A portable computer design featuring a displayer that can pivot between landscape and portrait modes using a supporting frame with straight and curved sliding slots, and a lock mechanism to secure the displayer in either mode, allowing for improved usability and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the displayer is fixed in landscape mode, then it is good for displaying movies, but it is not suitable for browsing web pages or editing articles
Solution Approach 1:
The displayer is designed to be dynamically adjustable between landscape and portrait modes through a pivot connection mechanism. The supporting frame includes sliding slots that guide the movement of sliding members, allowing the displayer to rotate and lock into different orientations based on usage requirements.
Solution Approach 2:
The connection mechanism is segmented into multiple functional components: the supporting frame with sliding slots, the displayer with sliding members, and the latch mechanism with latches and drive members. This segmentation allows independent optimization of each component's function while achieving the overall goal of mode switching.
2Adaptability or versatility
If the disdisplay can rotate freely, then it can switch between modes, but it cannot be securely positioned in either mode
Solution Approach 1:
The latch mechanism is designed to proactively secure the displayer in the desired position before any accidental movement can occur. The latches can be engaged with the supporting frame at predetermined positions, creating a stable locked state that prevents unintended rotation while maintaining the ability to switch modes when deliberately actuated.
3Stability of the object's composition
If a lock mechanism is added to secure the displayer, then accidental rotation is prevented, but the structure becomes more complex
Solution Approach 1:
The lock mechanism is merged with the existing pivot connection structure. The latches work in conjunction with the sliding members and sliding slots, utilizing the same spatial envelope and movement paths. This integration allows the locking function to be added without requiring separate structural elements, thereby minimizing the increase in overall complexity.

AI summary
A portable computer includes a host, a supporting frame, a displayer, two latches and a drive member. The supporting frame is pivotally connected with the host and having a straight sliding slot and a curved sliding slot. The displayer has two sliding members, which are pivotally connected with the supporting frame and slidably connected with the straight sliding slot and the curved sliding slot respectively. The displayer is operable to rotate relative to the supporting frame by either one of the two sliding members as a pivot. The two latches are slidably connected with the supporting frame. The drive member is slidably connected with the two latches and operable to control where either one of the two latches is located.
