Solution Overview

Problem

Existing mobile Information Handling Systems (IHS) devices struggle to provide versatility across various use-cases and display postures, while also offering a larger display area with reduced size and weight.

Innovation Solution

A multi-form factor IHS system that includes a processor and memory with program instructions to produce a work area on a second display coupled to a first display via a hinge, detect a keyboard placement, and adjust the work area to accommodate the keyboard, thereby optimizing the user interface and display configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional 2-in-1 device combines the portability of a tablet with the performance of a notebook, then portability and performance are improved, but the display area is reduced resulting in an uncomfortable form factor

Engineering Contradiction:
Improveversatility across use-cases and display posturesVSAvoiddisplay area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The system dynamically adjusts the work area and user interface based on keyboard placement detection. When a keyboard is detected on the second display, the system automatically modifies the display configuration to accommodate it, enabling the device to adapt between tablet mode and laptop mode without manual intervention, thus resolving the contradiction between versatility and display area

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The second display serves multiple functions: it can be used as a full display surface when no keyboard is present, or as a keyboard support surface when a keyboard is placed on it. This multi-functionality allows the device to maintain versatility across different use-cases while preserving the full display area when needed

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

2Ease of operation

If the work area is reduced to accommodate keyboard placement, then the user interface becomes optimized for keyboard use, but the available display space decreases

Engineering Contradiction:
Improveuser interface optimizationVSAvoidwork area
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The work area is dynamically adjusted based on keyboard detection. The system continuously monitors for keyboard placement and automatically modifies the work area configuration, transitioning between full-screen mode and keyboard-accommodating mode, thus optimizing ease of operation without permanently reducing display space

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the display parameters (work area boundaries, UI element positioning) in response to keyboard detection. By modifying these parameters dynamically, the system optimizes the user interface for keyboard use when needed while restoring full display area when the keyboard is removed

Inventive Principle:
Principle #35Parameter changes

AI summary

Embodiments of systems and methods for application management for a multi-form factor Information Handing System (IHS) are described. In an illustrative, non-limiting embodiment, an IHS may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to: produce a work area on a second display, wherein the second display is coupled to a first display via a hinge; detect that a keyboard is placed on the second display; and in response to the detection, reduce the work area into one or more areas unobstructed by the keyboard.
