Solution Overview

Problem

Current methods for decorating laminated panels fail to achieve continuity of design between the front and lateral surfaces, requiring manual application and limiting the ability to create complex designs, especially when the panel is not made of a single wooden board.

Innovation Solution

A method using inkjet printing and computer vision to detect and print designs on substrates, ensuring continuity between the front and lateral surfaces by generating and adjusting designs based on the positioning and patterns of the laminar elements, allowing for automated and precise application of complex designs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual application of design is used on substrate edges, then complex designs can be applied, but productivity is low and cost is high

Engineering Contradiction:

Improvedesign complexityVSAvoiddecoration speed

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent replaces manual mechanical application of design materials with an automated inkjet printing system. The printing device deposits material jet by jet according to digitally stored design patterns, eliminating the need for manual application while maintaining the ability to create complex designs through digital programming

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses digital copies of design patterns stored in memory to guide the automated printing process. The design is replicated precisely through digital data rather than manual replication, enabling consistent reproduction of complex patterns at high speed

Inventive Principle:

Principle #26Copying

2Reliability

If manual repair of designs is performed, then design continuity can be maintained, but loss of time increases

Engineering Contradiction:

Improvedesign continuityVSAvoidrepair time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces manual inspection and repair processes with automated optical detection systems and computer-controlled printing. The system automatically detects design defects and triggers automated repair printing, eliminating manual intervention and significantly reducing repair time while maintaining design continuity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements a feedback loop where the printing process is monitored and controlled based on detected conditions. When design continuity issues are detected, the system automatically adjusts the printing parameters and reprints the affected areas, ensuring continuous quality without manual intervention

Inventive Principle:

Principle #23Feedback

3Productivity

If inkjet printing is used for design application, then productivity increases and automation is achieved, but manufacturing precision requirements increase

Engineering Contradiction:

Improvedecoration speedVSAvoiddesign placement accuracy

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent replaces manual positioning with automated optical detection and computer-controlled printing systems. The system uses optical means to detect the substrate and design positions, then automatically calculates and executes precise printing locations, achieving high precision through digital control rather than manual skill

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses digital copying and processing of design patterns to maintain precision. The design is stored as digital data that can be precisely reproduced and positioned automatically, eliminating the variability inherent in manual placement while maintaining exact design fidelity

Inventive Principle:

Principle #26Copying
