Solution Overview

Problem

Laptop computers typically have display screens positioned low, requiring users to lower their heads for viewing, leading to poor user experience and potential health issues.

Innovation Solution

A connection device with a first rotation assembly and a support assembly that allows the display device to rotate relative to the system terminal, enabling the display to be lifted or lowered for improved viewing angles and reducing cervical strain.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the display screen is positioned at a low location to maintain a compact device structure, then the device complexity is reduced, but the user experience deteriorates due to the need to lower the head for viewing

Engineering Contradiction:
Improvedevice structureVSAvoiduser experience
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent implements a dynamic display positioning system with rotation assemblies that allow the display screen to rotate between multiple positions (low position for compact storage, high position for comfortable viewing). This transforms the static display position into a dynamic one, enabling the system to adapt between compactness and user comfort based on usage requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces rotational movement in the vertical dimension, allowing the display screen to transition between low and high positions. This dimensional change enables the system to overcome the trade-off between compact structure and viewing comfort by adding a vertical rotation degree of freedom.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If the display screen is positioned at a low location, then the device structure remains compact, but cervical strain increases due to prolonged head lowering

Engineering Contradiction:
Improvedevice structureVSAvoidcervical strain
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The rotation assembly enables dynamic adjustment of display height, allowing users to switch between compact low-position storage and ergonomic high-position viewing. This dynamic capability eliminates prolonged exposure to harmful viewing angles, reducing cervical strain while maintaining structural compactness.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotation mechanism is designed to be user-operable, allowing individuals to independently adjust the display position to their comfort needs. This self-service capability empowers users to eliminate cervical strain without requiring external assistance or complex automated systems.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the display device is rotated to a high position for comfortable viewing, then user experience is improved, but the device structure becomes more complex

Engineering Contradiction:
Improveuser experienceVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent divides the connection structure into modular rotation assemblies (first rotation assembly and second rotation assembly) that can be independently configured. This segmentation allows the complex rotation function to be broken down into manageable components, simplifying manufacturing and assembly while achieving the desired high-position display capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs nested rotation mechanisms where the second rotation assembly is integrated within or alongside the first rotation assembly. This nesting approach consolidates multiple rotational functions into a compact integrated structure, achieving high-position display capability without proportionally increasing overall device complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A connection device includes a first rotation assembly including a first connection member, a second rotation assembly rotatably connected to the first rotation assembly and configured to rotate relative to the first rotation assembly to cause relative displacement between a first member and a second member of the second rotation assembly, and a support assembly connected to the first member and the second member. The support assembly includes a second connection member configured to move relative to the first connection member when the second rotation assembly rotates relative to the first rotation assembly.
