Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a large number of applications are displayed in a list format, then users can access various applications, but the display screen becomes cluttered and difficult to operate

Engineering Contradiction:
Improveapplication accessibilityVSAvoidscreen operability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent segments the application list into multiple pages, with each page displaying a subset of applications. Users can navigate between pages to access different groups of applications, preventing screen clutter while maintaining access to all applications through structured division of the application set.

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If icons are arranged in a grid pattern, then screen space is utilized efficiently, but users have limited control over icon placement and customization

Engineering Contradiction:
Improvescreen space utilizationVSAvoidicon arrangement flexibility
Core Design Contradiction:
Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic icon arrangement system where icons can be freely moved and repositioned by users within the grid structure. The system adapts to user preferences by allowing custom placement while maintaining the overall grid organization, combining efficient space utilization with flexible customization capability.

Inventive Principle:
Principle #15Dynamics

3Loss of information

If detailed application information is displayed, then users can make informed decisions, but the interface becomes complex and harder to navigate

Engineering Contradiction:
Improveinformation completenessVSAvoidinterface complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent implements a progressive information disclosure mechanism where users interact with icons in stages - first seeing basic icon representations, then accessing detailed information through sequential actions like clicking or long-pressing. This periodic revelation of information levels provides complete details when needed while maintaining a simple initial interface view.

Inventive Principle:
Principle #19Periodic action
