Solution Overview

Problem

Conventional digital painting applications require significant user skill and precision to create desired artistic effects, and tools like the 'paint bucket' lack tactile experience and are inefficient for partially bounded regions.

Innovation Solution

An interactive region coloring system that determines the manner of digital paint application based on distance and direction values from the outline, allowing dynamic brush size and position adjustments, and using a fluid paint simulation system to mimic the flow of paint, enabling users to fill regions with precision and skill without fully enclosing them.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional painting tools like paint bucket are used, then filling speed is improved, but tactile experience and precision are lost

Engineering Contradiction:

Improvefilling speedVSAvoidtactile experience

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system dynamically adjusts brush characteristics (size, flow rate, opacity) based on real-time conditions such as distance to outline, paint accumulation, and user stroke patterns. This dynamic adaptation allows the digital paint to behave more like physical paint, providing tactile feedback while maintaining efficient filling capability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes multiple parameters simultaneously including brush size, paint viscosity, flow rate, and opacity based on the distance to the outline and accumulated paint layers. This multi-parameter adjustment creates a more realistic painting experience while maintaining productivity.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If conventional painting tools are used, then operation simplicity is improved, but precision and skill input are reduced

Engineering Contradiction:

Improveoperation simplicityVSAvoidprecision

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The system provides continuous feedback to the user by detecting brush position, stroke direction, and paint accumulation, then adjusting paint flow and brush characteristics in real-time. This feedback loop allows users to maintain simple operations while achieving precise results through the system's intelligent adjustments.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system automatically adjusts paint flow, brush size, and opacity based on detected conditions without requiring manual user intervention. The system serves itself by monitoring its own state and making corrections, thereby maintaining precision while keeping the user interface simple.

Inventive Principle:

Principle #25Self-service

3Productivity

If paint bucket tool is used, then filling efficiency is improved, but adaptability to partially bounded regions is worsened

Engineering Contradiction:

Improvefilling efficiencyVSAvoidadaptability to partially bounded regions

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adapts brush behavior based on the boundaries detected in the region. For partially bounded regions, the brush automatically adjusts its flow and distribution patterns to work effectively with open boundaries, maintaining filling efficiency while adapting to various region types.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The digital paint application system is designed to handle multiple region types (fully enclosed, partially bounded, open regions) with the same tool, eliminating the need for different tools for different scenarios. This universal approach maintains efficiency across all region types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Manufacturing precision

If mask layer is used, then precision in preventing paint application is improved, but user skill and artistic control are reduced

Engineering Contradiction:

Improveprecision in paint application controlVSAvoiduser skill and artistic control

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

Instead of using masks to prevent paint application (restrictive approach), the system uses intelligent brush behavior to naturally guide paint toward desired areas through flow dynamics and boundary detection. This inverted approach maintains user control while achieving precision without restrictions.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

Interactive region coloring techniques as implemented by a computing device are described to provide a user with the tactile experience of coloring in a region with digital paint, while at the same time allowing the user to manually fill the region with digital paint with more apparent skill and precision than they may input. For each of multiple pixels on the digital medium, the system obtains one or both of a distance value that indicates a distance to a nearby point (e.g., the closest point) on an outline on the digital medium and a direction value that indicates a direction to the nearby point on the outline. A manner in which the digital paint is applied to the region (e.g., forces affecting paint flow, dynamically adjusting brush size or position) is determined based on one or both of the distance value and the direction value.
