Solution Overview

Problem

Conventional mobile devices with concealed keyboards face challenges in maintaining compact size while providing full functionality, as they often compromise on display size or keyboard accessibility.

Innovation Solution

The design incorporates a first housing with a display screen and a second housing that contains a concealed keyboard, which can be rotated to expose the keyboard, allowing for a compact closed configuration and a full-sized keyboard experience in an open configuration, with a concealment cover that acts as a stand for the display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a concealed keyboard is integrated into the mobile device, then keyboard functionality is provided, but the device size increases and compactness is compromised

Engineering Contradiction:
Improvekeyboard functionalityVSAvoiddevice size
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The keyboard is nested within the display assembly, specifically integrated into the bezel area surrounding the display. This allows the keyboard to be concealed when not in use, maintaining a compact device profile, while being readily accessible when needed for typing or data entry functions.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The keyboard is designed to be dynamically reconfigurable, allowing it to be concealed or exposed based on user needs. The keyboard can be rotated or folded away from the display area, enabling the device to transition between a compact configuration for portability and an expanded configuration for keyboard usage.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the keyboard is exposed for full accessibility, then typing comfort is improved, but the display size is reduced due to space requirements

Engineering Contradiction:
Improvetyping comfortVSAvoiddisplay size
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The keyboard is positioned in the bezel area, utilizing the local space around the display rather than encroaching on the display area itself. This allows the display to maintain its full size while the keyboard provides tactile input capability in a dedicated local region that does not compromise screen real estate.

Inventive Principle:
Principle #3Local quality

3Volume of moving object

If the keyboard is concealed to maintain compact size, then device portability is improved, but keyboard accessibility is reduced

Engineering Contradiction:
Improvedevice compactnessVSAvoidkeyboard accessibility
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The keyboard assembly is designed to be dynamically reconfigurable, allowing it to be concealed or exposed based on user needs. The keyboard can be rotated or folded away from the display area, enabling the device to transition between a compact configuration for portability and an expanded configuration for keyboard usage.

Inventive Principle:
Principle #15Dynamics

4Object-affected harmful factors

If a concealment cover is added to protect the keyboard, then keyboard protection is improved, but device complexity increases

Engineering Contradiction:
Improvekeyboard protectionVSAvoiddevice complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The concealment cover is merged with the keyboard assembly itself, forming an integrated unit. The cover serves dual purposes: protecting the keyboard when concealed and serving as part of the structural assembly when the keyboard is in use. This integration minimizes additional components and reduces overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An electronic device having a concealed keyboard includes a first housing, a second housing rotatably coupled to the first housing, and a concealment cover coupled to a rear of the first housing. The first housing has a coupling edge and two sides that are substantially perpendicular to the coupling edge of the first housing. The second housing has a coupling edge and two sides that are substantially perpendicular to the coupling edge of the second housing. A receiving portion is formed on a rear surface of the first housing and is configured to receive the second housing. When the second housing is in the receiving portion, each respective side of the first housing and the second housing are co-terminal with one another. The concealment cover is exteriorly positioned with respect to the second housing when the second housing is in the receiving portion.
