Solution Overview

Problem

Conventional mobile devices require users to navigate through multiple screen pages to access communication-related functions, causing inconvenience.

Innovation Solution

A mobile device with a touch-sensitive interface allows users to select an item in a scrollable communication-related list through a first touch event and execute a predefined function with a subsequent touch event without additional page views.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users navigate through multiple screen pages to access communication functions, then function accessibility is improved, but operation complexity increases

Engineering Contradiction:
Improvefunction accessibilityVSAvoidnavigation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines multiple screen pages into a single integrated list where communication functions (call, message, email) are directly accessible from each contact item. This merging eliminates the need to navigate through separate pages for searching, viewing details, and executing functions, thereby reducing navigation complexity while maintaining full functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The list item serves multiple functions simultaneously: it displays contact information, provides navigation to communication functions, and enables direct execution of calls, messages, and emails. This multi-functionality consolidates what would traditionally require multiple dedicated screens into a single universal interface.

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

2Adaptability or versatility

If multiple screen pages are used for communication functions, then function completeness is improved, but user convenience deteriorates

Engineering Contradiction:
Improvefunction completenessVSAvoiduser convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges the completeness of multiple communication functions (search, view details, call, message, email) into a single accessible list view. All functions remain complete and functional, but are now accessible without requiring users to navigate through multiple pages, thereby improving convenience while preserving function completeness.

Inventive Principle:
Principle #5Merging (Combining)

3Measurement precision

If traditional keypad is used, then input precision is improved, but device portability deteriorates

Engineering Contradiction:
Improveinput precisionVSAvoiddevice size
Core Design Contradiction:
Measurement precisionVSVolume of moving object

Solution Approach 1:

The patent replaces the mechanical keypad system with a touch-sensitive display interface. This substitution eliminates the need for physical keys, reducing device volume and enhancing portability, while the touch interface provides sufficient input precision for selecting list items and executing communication functions.

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

AI summary

A mobile device and a touch-based operation method allow a user to easily and conveniently use a desired communication-related function through a touch-sensitive interface. The mobile device displays a scrollable communication-related list that includes but is not limited to a call log list, a message list, a phonebook list, and an email list. When a specific item is selected in response to a first touch event, the mobile device determines whether or not a second touch event occurs on the selected item in a non-scrollable direction. Then the mobile device executes a particular function predefined in the selected item in response to the second touch event occurring in the non-scrollable direction.
