Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional button selection and simple touch screen interactions are used, then device structure remains simple, but user interaction capability cannot keep pace with diverse functions and content types

Engineering Contradiction:
Improveuser interaction capabilityVSAvoidinteraction system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The touch screen is divided into multiple independent interaction regions including a first interaction region and a second interaction region. Each region can independently respond to user inputs and execute different interaction modes, allowing the system to handle diverse functions without increasing overall structural complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The interaction regions are configured to dynamically change their functionality based on user gestures. The same physical region can serve different purposes depending on the type of gesture detected, enabling versatile interaction capabilities while maintaining a simple static screen structure

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the touch screen is divided into multiple interaction regions, then user interaction versatility improves, but screen structure complexity increases

Engineering Contradiction:
Improveinteraction region functionalityVSAvoidscreen structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each interaction region is designed to support multiple interaction modes including clicking, dragging, and long-press operations. The same region can function as a selection area, a navigation zone, or a gesture recognition space depending on the context, eliminating the need for separate specialized components for each function

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

Solution Approach 2:

The patent introduces temporal dimension to the interaction by recognizing different gesture durations (short press vs long press) and movement patterns. This allows the same spatial region to provide differentiated functionality through time-based gesture variations, increasing interaction versatility without adding spatial complexity

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If diverse interaction gestures are supported, then user convenience improves, but processing complexity increases

Engineering Contradiction:
Improveuser convenienceVSAvoidgesture processing complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Different interaction regions are assigned different gesture recognition capabilities and processing rules. The first interaction region may be optimized for selection gestures while the second region handles navigation gestures, allowing each region to process only the gestures relevant to its function, reducing overall processing complexity

Inventive Principle:
Principle #3Local quality

AI summary

Disclosed is a user interaction method of a user terminal device including a bent touchscreen. The present invention comprises the steps of: displaying a UI element associated with an external device on a sub-region if the external device, located outside of a user terminal device, and the user terminal device are connected to be able to communicate with each other; and performing a function associated with the UI element in response to a user gesture selecting the UI element. Accordingly, interaction can be performed in various ways.
