Solution Overview

Problem

Existing tablet keyboards with rotating shaft brackets provide poor user experience due to inconvenience in using keys on the upper part of the keyboard and a close proximity of the tablet computer's bottom to the keys, affecting usability.

Innovation Solution

A pull-out keyboard assembly featuring a base bracket mechanism with sliding grooves and magnetic members for fixation, along with ball assemblies for easy movement and a protective housing for adjustment, allowing for convenient positioning and secure attachment of the keyboard mechanism to the base bracket.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the keyboard is fixed to a bracket with a rotating shaft, then the viewing experience for the screen is improved, but the user experience for typing on upper part keys deteriorates due to close proximity of the tablet bottom to the keys

Engineering Contradiction:
Improveviewing experienceVSAvoidtyping comfort
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The keyboard assembly is divided into a fixed base bracket mechanism and a movable keyboard mechanism that can be independently positioned. The keyboard mechanism can be pulled out along sliding grooves to extend the distance between the tablet bottom and the keyboard keys, resolving the contradiction between maintaining viewing angle and improving typing comfort.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The keyboard mechanism transitions from a fixed position to a movable position through sliding grooves and magnetic restraint. Users can dynamically adjust the keyboard position by pulling it out or pushing it in, allowing optimization of both viewing experience and typing comfort based on different usage scenarios.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the keyboard mechanism is made movable to improve user experience, then typing comfort is improved, but the device complexity increases due to additional sliding grooves and magnetic members

Engineering Contradiction:
Improvekeyboard positioning convenienceVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Traditional mechanical locking mechanisms are replaced with magnetic restraint systems. The magnetic members automatically attract and hold the keyboard mechanism at desired positions, eliminating the need for complex mechanical locks while providing smooth movement through sliding grooves.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic restraint system provides automatic positioning and holding functionality. When the keyboard mechanism is moved to a desired position, the magnetic members automatically engage to maintain that position without requiring additional mechanical components or manual locking actions.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If magnetic members are used for fixation at different positions, then ease of positioning is improved, but the manufacturing precision requirements increase for proper magnetic alignment

Engineering Contradiction:
Improvepositioning convenienceVSAvoidmagnetic member alignment
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The magnetic restraint function is extracted as a separate system from the main structural components. The sliding grooves provide mechanical guidance while the magnetic members provide independent positioning and holding, separating the guidance function from the positioning function to reduce precision requirements.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The sliding grooves act as an intermediary between the fixed base and the movable keyboard mechanism. They provide mechanical constraints that guide movement while the magnetic members provide fine positioning, dividing the precision requirements between the two systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

The solution enhances user experience by allowing easier and more convenient keyboard positioning with reduced force required for movement, preventing the keyboard from falling off, and enabling adjustment within limited space, thus improving usability and comfort during typing.

Implementation Method 1

the multiple second magnetic members respectively mutually attract the corresponding first magnetic members, to implement fixation at different relative positions of the keyboard mechanism and the base bracket mechanism
