Solution Overview

Problem

Consumers face difficulties in selecting paints due to the challenge of mentally projecting small paint chips or digital images to full-size walls, as perceived lightness and chroma change when scaling up, making it hard to accurately choose colors for large surfaces.

Innovation Solution

A system that displays device-dependent colors on a full-size room or wall using LEDs, allowing users to interactively select and visualize colors, with a library matching true colors to device-dependent coordinates, and suggesting harmonious colors, while also dispensing corresponding paints.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If small paint chips are used for color selection, then the cost is low and the process is simple, but the perceived lightness and chroma change when scaling up to wall size, making accurate color selection difficult

Engineering Contradiction:
Improvecolor accuracyVSAvoiddisplay size
Core Design Contradiction:
Measurement precisionVSArea of stationary object

Solution Approach 1:

The patent uses full-size wall panels that replicate actual wall surfaces and apply paint samples directly to them, creating accurate physical copies of the final application. This eliminates the need for mental projection from small chips and allows buyers to see true color appearance at full scale.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system transitions from two-dimensional small paint chips to three-dimensional full-size wall panels that simulate actual wall conditions. This dimensional change allows buyers to experience color in the context of full-scale surfaces with proper lighting and texture.

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

2Measurement precision

If larger paint chips or sample paints are used to improve color visualization, then color accuracy improves, but the cost increases and the selection process becomes more time-consuming

Engineering Contradiction:
Improvecolor accuracyVSAvoidselection time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system pre-prepares multiple full-size wall panels with different paint colors already applied and displayed. Buyers can immediately view and compare multiple color options without waiting for samples to be prepared or mixed, significantly reducing selection time while maintaining color accuracy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The wall panels serve multiple functions: they display color accuracy, simulate final application appearance, provide lighting conditions, and allow direct comparison of multiple colors. This multi-functionality consolidates what would otherwise require multiple separate steps into a single viewing experience.

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

3Productivity

If digital images are used for color display, then the process becomes more efficient, but buyers must still mentally project the images to full-size walls, losing color accuracy

Engineering Contradiction:
Improveselection efficiencyVSAvoidcolor accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

Instead of using digital images that require mental projection, the system creates physical full-size wall panels with paint actually applied to them. This physical copy eliminates the projection step entirely and allows buyers to directly observe true color appearance under controlled lighting conditions.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system replaces the digital image display mechanism with a physical wall panel system. This substitution eliminates the need for screens, projectors, and digital processing, while providing direct visual feedback that accurately represents the final painted surface.

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

AI summary

A method for selecting paints is disclosed. This method includes the steps of selecting true paint colors, displaying device-dependent colors corresponding to the true paint colors in a simulated full size room and interacting with the buyers to change the displayed colors and select the desired colors. The method also includes the step of dispensing paints corresponding to the selected colors. The displayed colors are generated by multiple color and/or white LEDs to provide a wider gamut of displayable colors and more color saturation and chromatic. A full-size apparatus for displaying paint colors using device-dependent colors is also disclosed.
