Solution Overview

Problem

Rotatable notebook computers experience instability during pivoting, leading to potential scratching of the host module and keyboard due to the display module swaying and colliding with the upper surface.

Innovation Solution

A pivoting mechanism with a moving component on the side of the display module that contacts the upper surface of the host module, guided by an arc-shaped track, to stabilize the display module's rotation, combined with a positioning structure using magnetic components for secure alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the pivoting mechanism is designed in the center of the display module, then the display module can rotate relative to the host module, but the display module sways easily and collides with the host module and keyboard, causing scratching

Engineering Contradiction:
Improvepivoting functionVSAvoidpivoting stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

A moving component (rolling or sliding) is introduced as an intermediary element between the display module and host module. This component moves along an arc-shaped track during pivoting, mediating the relative motion and preventing direct contact between the display module bottom and the host module/keyboard surface, thereby preventing scratching while enabling pivoting functionality

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

An arc-shaped track is designed on the host module surface instead of a straight or flat path. This curved trajectory matches the natural arc of the pivoting motion, guiding the moving component smoothly along the rotation path and ensuring stable, controlled movement that prevents instability and collision during pivoting operations

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Adaptability or versatility

If the display module pivots relative to the host module, then the device can switch between notebook and tablet modes, but the bottom of the display module collides with the upper surface of the host module and keyboard

Engineering Contradiction:
Improveusing modesVSAvoidcollision and scratching
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The moving component serves as a protective intermediary that contacts the host module surface during pivoting. This component absorbs the interaction forces and prevents the display module bottom from directly contacting and scratching the host module and keyboard surfaces, enabling safe mode switching

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The moving component is positioned in advance to contact the host module surface before the display module bottom can collide with it. This proactive arrangement cushions the pivoting motion and prevents harmful collisions and scratching from occurring in the first place

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A portable electronic device includes a host module, a display module, a pivoting mechanism and a moving component. The pivoting mechanism is connected to the host module and the display module and for pivoting the host module relative to the display module. The pivoting mechanism includes a base and a pivoting unit. The pivoting unit includes a lower pivoting component and an upper pivoting component. The lower pivoting component is installed on the base. The upper pivoting component is pivotally connected to the lower pivoting component in a first pivoting direction and installed on the display module, so that the display module rotates relative to the host module in the first pivoting direction. The moving component contacts an upper surface of the host module and moves relative to the upper surface as the display module rotates relative to the host module in the first pivoting direction.
