Linking-Up Member for Rotating Display Orientation

Solution Overview

Problem

Conventional electronic devices, such as notebook computers, face operational inconvenience and visual discomfort due to fixed display orientations that require users to scroll or reduce display ratios to view information, limiting user preference for display ratios.

Innovation Solution

An electronic device design featuring a first body and a second body connected via a linking-up member with a shaft portion and a sliding slot, allowing the first body to rotate between landscape and portrait modes by combining linear and curved strokes, enabling a preferred display ratio and improved user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a rotation shaft between display unit and device body is used for motion mechanism, then the display unit can be expanded relative to the device body, but the display direction is fixed in landscape mode, causing operational inconvenience and visual discomfort

Engineering Contradiction:

Improvedisplay orientationVSAvoidoperation convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies dynamics by transforming the static rotation shaft mechanism into a dynamic system where the display unit can rotate between landscape and portrait modes. The linking-up member with sliding slot and cam mechanism enables the display unit to change its orientation dynamically, allowing users to switch between different display directions based on their needs, thus improving adaptability while maintaining ease of operation through automatic or assisted rotation.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a rotation shaft between display unit and device body is used for motion mechanism, then the display unit can be expanded relative to the device body, but the display direction is fixed in landscape mode, causing visual discomfort

Engineering Contradiction:

Improvedisplay orientationVSAvoidvisual discomfort

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies dynamics by transforming the static rotation shaft mechanism into a dynamic system where the display unit can rotate between landscape and portrait modes. The linking-up member with sliding slot and cam mechanism enables the display unit to change its orientation dynamically, allowing users to switch between different display directions based on their needs, thus improving adaptability while maintaining ease of operation through automatic or assisted rotation.

3Area of stationary object

If the display unit is expanded in landscape mode, then the display area is increased, but users must scroll back and forth or decrease display ratio to capture entire information

Engineering Contradiction:

Improvedisplay areaVSAvoidtime for scrolling

Core Design Contradiction:

Area of stationary objectVSLoss of time

Solution Approach 1:

The patent applies dynamics by transforming the static rotation shaft mechanism into a dynamic system where the display unit can rotate between landscape and portrait modes. The linking-up member with sliding slot and cam mechanism enables the display unit to change its orientation dynamically, allowing users to switch between different display directions based on their needs, thus improving adaptability while maintaining ease of operation through automatic or assisted rotation.

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

Enables users to change display orientations seamlessly, reducing the need for scrolling or reducing display ratios, thereby enhancing operation convenience and mitigating visual discomfort.

Implementation Method 1

The linking-up member is respectively coupled to a first restriction member and a second restriction member on the second body. The first restriction member provides a first stroke of a linear path and the second restriction member provides a second stroke of a curved path to the linking-up member respectively. When the first body is opened relative to the second body, the liking-up member combines the first stroke and the second stroke to drive the first body to rotate relative to the second body.

AI summary

An electronic device including a first body, a second body, and a linking-up member is provided. The second body connected to the first body is capable of being opened and closed relative to the first body. The second body has a first and second restriction member. The linking-up member is assembled to the first body. Two opposite ends of the linking-up member is coupled to the first restriction member and the second restriction member respectively, where the first restriction member provides a first stroke and the second restriction member provides a second stroke to the linking-up member. One of the first stroke and the second stroke is a linear path and another one is a curved path. When the first body is expanded relative to the second body, the liking-up member combines the first stroke and the second stroke to drive the second body rotating relative to the first body.
