Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional screen splitting methods are used (pressing and holding, menu selection, or dragging to activation area), then screen splitting functionality is achieved, but the operation becomes complex and not intuitive for users

Engineering Contradiction:
Improvescreen splitting operationVSAvoidoperation steps
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system pre-arranges preview cards of multiple applications in a specific layout on the multi-application switching interface. By preparing the interface in advance with clearly positioned preview cards, users can directly interact with the cards without needing to perform complex preliminary actions like menu selection or finding activation areas, thereby simplifying the screen splitting operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The preview cards on the multi-application switching interface are designed to be directly draggable by users. The cards themselves serve as the interaction target, eliminating the need for separate activation areas or menu selections. Users can intuitively perform screen splitting by simply dragging the preview cards to desired positions, making the system self-explanatory and easy to operate.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If conventional screen splitting methods are used, then screen splitting is achieved, but the operation is difficult for users to find and understand

Engineering Contradiction:
Improveintuitiveness of screen splittingVSAvoidvisibility of screen splitting function
Core Design Contradiction:
Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The preview cards on the multi-application switching interface are designed with distinct visual characteristics that make them easily identifiable and distinguishable from other interface elements. This visual design helps users quickly locate and understand the screen splitting function without needing to search for activation areas or menu options, thereby improving the intuitiveness and visibility of the feature.

Inventive Principle:
Principle #32Color changes

3Adaptability or versatility

If multiple applications are displayed simultaneously using conventional methods, then multi-application functionality is achieved, but the interface requires complex navigation and switching

Engineering Contradiction:
Improvemulti-application display capabilityVSAvoidapplication switching operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The interface is segmented into multiple preview cards, each representing a separate application. This segmentation allows users to visually distinguish between different applications and their states, making it easier to manage and switch between multiple applications simultaneously without complex navigation requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from traditional sequential application switching to a spatial arrangement where multiple application preview cards are displayed simultaneously in a two-dimensional layout. This dimensional change allows users to access multiple applications at once through direct spatial interaction rather than sequential switching, greatly enhancing multi-application display capability and ease of operation.

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