Solution Overview

Problem

Conventional laptops with mixed configurations are inconvenient for use due to similarities in design, making them less competitive with tablet computers in terms of usability.

Innovation Solution

A laptop design featuring a screen articulated to a base via a rotating device with a guide rail, allowing the screen to slide and rotate about an articulated shaft, providing various usage modes and improved portability by reducing the thickness of the rotating device while maintaining strength.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the screen is articulated to the base via a conventional hinge mechanism, then the laptop can be used in traditional modes, but the device thickness and weight are increased, reducing portability

Engineering Contradiction:
ImproveusabilityVSAvoiddevice weight
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The patent applies a dynamic rotating device that allows the screen to rotate about an articulated shaft while sliding along guide rails, transitioning from a fixed hinge connection to a dynamic multi-position mechanism. This enables the screen to be positioned at various angles and locations, providing both laptop and tablet usage modes while reducing overall device thickness and weight compared to conventional rigid hinge designs

Inventive Principle:
Principle #15Dynamics

2Weight of moving object

If the rotating device thickness is reduced to improve portability, then the device becomes more portable, but the structural strength and stability may be compromised

Engineering Contradiction:
Improvedevice thicknessVSAvoidrotating device strength
Core Design Contradiction:
Weight of moving objectVSStrength

Solution Approach 1:

The rotating device is segmented into multiple functional components: an articulated shaft for rotation, guide rails for linear movement, and a screen assembly that slides along the rails. This segmentation allows each component to be optimized independently - the shaft provides rotational strength while the guide rails provide lateral support, achieving sufficient structural strength with reduced overall thickness

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rotating device employs composite structural design combining the articulated shaft, guide rails, and screen assembly into an integrated mechanism. This composite structure distributes mechanical loads across multiple elements, maintaining strength and stability while reducing the thickness of individual components and the overall device

Inventive Principle:
Principle #40Composite materials

3Adaptability or versatility

If a mixed configuration laptop is designed to function as both laptop and tablet, then versatility is improved, but the design becomes similar to conventional laptops, reducing user convenience

Engineering Contradiction:
Improveusage modesVSAvoiduser convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The dynamic rotating device with guide rails enables the screen to move beyond fixed angular positions, allowing smooth transitions between laptop mode (screen at angle), tablet mode (screen parallel to base), and intermediate positions. This dynamic positioning system provides genuine versatility while maintaining ease of operation through intuitive, continuous motion rather than discrete mode switching

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotating device with guide rails serves multiple functions: it enables rotation for angular positioning, provides linear sliding for parallel positioning, and allows intermediate positions for various usage scenarios. This multi-functional mechanism achieves true adaptability between laptop and tablet modes while improving user convenience through a unified, flexible design

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A laptop includes a screen and a base having a keyboard. An end of the screen is articulated to an end of the base via a rotating device; and a first distance between a bottom edge of the screen and a bottom edge of the keyboard is smaller than a second distance between a top end of the screen and the bottom edge of the keyboard when the screen is closed onto the base. A guide rail is provided at two sides of the base, and the screen is slidable along the guide rail. The rotating device includes an articulated shaft connected to the base; and at any position on the guide rail, the screen is rotatable about the articulated shaft. When the screen is closed onto the base, the display surface of the screen faces outwards, thus the user can use the laptop in a tablet computer mode.
