Solution Overview

Problem

There is a growing demand for building boards with superior three-dimensional appearances and textures that mimic processed lumber, as conventional designs lack the desired depth and realism in wood grain patterns.

Innovation Solution

A building board featuring a base material with intersecting recesses and protrusions, coated with a lighter first coating on the protrusions and a darker second coating on the recesses, creating a three-dimensional appearance and texture that resembles manually processed lumber, achieved through specific painting methods and coating configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If conventional building boards with wood grain textured designs are used, then installation simplicity is maintained, but the three-dimensional appearance and texture realism are insufficient

Engineering Contradiction:
Improvethree-dimensional appearanceVSAvoidsurface structure complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The building board surface is segmented into multiple patterned regions demarcated by joint-like grooves, with each region containing wood grain forming protrusions and intersecting recesses. This segmentation creates a three-dimensional textured appearance that mimics processed lumber while maintaining modular installation simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different surface regions are given different local qualities through the combination of wood grain forming protrusions (providing grain texture) and intersecting recesses (providing depth and shadow). The dual-coating system further enhances local quality by applying different coatings to different surface features, creating realistic wood appearance variations.

Inventive Principle:
Principle #3Local quality

2Shape

If dual coating system with different lightness is applied, then visual realism and three-dimensional effect are improved, but manufacturing process complexity increases

Engineering Contradiction:
Improvevisual depth and textureVSAvoidcoating process complexity
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The joint-like grooves and intersecting recesses are formed in advance on the base material board before coating application. This preliminary structuring allows the dual-coating system to efficiently create three-dimensional effects, as the recesses naturally trap and hold the second coating, reducing the need for complex manual application techniques.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The dual-coating system utilizes color/lightness changes to enhance visual realism. The first coating provides a base color while the second coating, with lower lightness, creates shadow effects in the intersecting recesses. This color differentiation mimics natural wood grain patterns and enhances the three-dimensional appearance without requiring complex manufacturing processes.

Inventive Principle:
Principle #32Color changes

3Manufacturing precision

If more surface features are added to express wood grain pattern, then texture realism is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvewood grain texture accuracyVSAvoidsurface feature complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The invention transitions from two-dimensional printed wood grain patterns to three-dimensional physical surface features. Wood grain forming protrusions and intersecting recesses create actual depth and texture that can be touched and felt, providing realistic wood grain appearance. This dimensional enhancement improves texture accuracy while the standardized geometric forms keep manufacturing within achievable precision ranges.

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

AI summary

A building board with an appearance being three-dimensional and having a texture of processed lumber and a method for manufacturing the same are provided. A building board includes a base material board, a patterned region formed on the base material board and demarcated by a first joint-like groove and a second joint-like groove intersecting the first joint-like groove, a plurality of wood grain forming protrusions that are formed in the patterned region so as to express a wood grain pattern, an intersecting recess that is formed in the patterned region to have a strip shape extending in a direction intersecting the plurality of wood grain forming protrusions, a first coating formed on the wood grain forming protrusions, and a second coating formed on the intersecting recess, the second coating having a lower lightness than the first coating.
