Solution Overview

Problem

Existing portable communication devices have inflexible and complex user interfaces, making it difficult for users to easily interact with multifunction devices, particularly when managing multiple email accounts and digital media content.

Innovation Solution

A portable multifunction device with a touch-sensitive display and a graphical user interface that allows users to interact primarily through finger contacts and gestures, providing features like fast inbox switching among multiple email accounts, a unified inbox, and easy access to digital media files.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If physical pushbuttons are added or their density is increased to provide more functions, then the number of accessible features increases, but the device complexity and difficulty of operation increase

Engineering Contradiction:

Improvenumber of accessible featuresVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The touch-sensitive display serves multiple functions: it displays visual information, accepts user input through finger contacts and gestures, and replaces traditional physical pushbuttons. This single component performs the roles of both display and input devices, reducing overall device complexity while maintaining versatility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent replaces mechanical pushbuttons with a touch-sensitive interface. Users interact with the display through finger contacts and gestures rather than physical button presses. This substitution eliminates the need for multiple physical buttons while providing equivalent or enhanced functionality through software-based controls.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If physical pushbuttons are added or their density is increased to provide more functions, then the number of accessible features increases, but the ease of operation decreases due to complicated key sequences and menu hierarchies

Engineering Contradiction:

Improvenumber of accessible featuresVSAvoidease of operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The touch-sensitive display allows users to directly interact with the interface by touching and gesturing on the display surface. Users can navigate menus, select options, and access features by directly touching the visual elements on screen, eliminating the need to learn complex key sequences or navigate deep menu hierarchies through physical buttons.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent adds the dimension of direct visual interaction by allowing users to touch and gesture on the display surface itself. This transforms the interface from a indirect physical button system to a direct visual-manual interaction system, where users can see and touch the same element, making operation more intuitive and easier to learn.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Volume of moving object

If the screen size is reduced to make the device more compact, then the portability improves, but the ease of interacting with email accounts and digital media files deteriorates

Engineering Contradiction:

Improvedevice compactnessVSAvoidease of interacting with email accounts

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The touch-sensitive display replaces physical navigation controls with direct finger contact and gesture-based interaction. Users can navigate email accounts, attach digital media files, and perform other operations by touching and gesturing on the display, which provides sufficient interaction capability even on compact devices with smaller screens.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The interface utilizes dynamic gestures and flexible interaction modes that can adapt to different screen sizes. The touch-sensitive display responds to various finger contacts and gestures, allowing users to interact with email accounts and digital media files effectively regardless of the specific screen dimensions, thereby maintaining ease of operation in compact form factors.

Inventive Principle:

Principle #15Dynamics

AI summary

A computer-implemented method is disclosed for use with a portable electronic device having a display. The method enables switching between electronic inboxes that can be accessed from the electronic device. In some configurations, the method includes, while the device is displaying emails in a first inbox, detecting user selection of a first icon. The method further includes, in response to user selection of the first icon, displaying a set of inbox selection icons; and, in response to user selection of one of the inbox selection icons, displaying emails in a second inbox corresponding to the inbox selection icon selected by the user.
