Laser-Embossed Woodgrain Decorative Material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of woodgrain finish decorative materials using embossing plates formed by electrocasting is expensive and time-consuming, resulting in prolonged production timelines and high costs due to the requirement for rare natural wood plates.
Innovation Solution
A raised woodgrain finish decorative material is created with specific raised sections and slope sections on a substrate, where the first raised section is longer and higher than the second raised section, and the slope section is incorporated to replicate the visual and tactile appearance of actual wood, using a laser-embossing process for efficient production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If embossing plates are formed by electrocasting using rare natural wood plates, then the raised visual design appearance and feeling are improved, but the production timeline is prolonged and costs increase
Solution Approach 1:
The invention creates a copy of the woodgrain pattern using a mold that can be repeatedly used for embossing, rather than requiring rare natural wood plates for each production run. The mold captures the essential woodgrain features and transfers them to the decorative material through embossing, eliminating the need for electrocasting from original wood plates.
Solution Approach 2:
The invention changes the production parameters by using a direct embossing process with controlled pressure and temperature, rather than the electrocasting process. This allows for faster production while maintaining the raised visual design appearance through optimized embossing conditions.
2Manufacturing precision
If embossing plates are formed by electrocasting using rare natural wood plates, then the raised visual design appearance and feeling are improved, but the production cost increases
Solution Approach 1:
The invention creates a reusable mold copy of the woodgrain pattern, eliminating the need for expensive rare natural wood plates. The mold can be produced from common materials and used repeatedly for embossing, significantly reducing material costs while maintaining design quality.
Solution Approach 2:
The invention replaces expensive, rare natural wood plates with cheaper, readily available materials for creating the embossing mold. The mold itself can be a simpler, more economical structure that achieves the same functional result without requiring precious natural resources.
3Quantity of substance
If the springwood part is expressed by gravure printing and the autumn wood part by relief printing or silkscreen printing, then the annual ring pattern is achieved, but the raised visual design appearance and feeling are insufficient
Solution Approach 1:
The invention merges the pattern formation and raised texture formation into a single embossing process. The mold simultaneously creates both the annual ring pattern and the raised three-dimensional appearance, eliminating the need for separate printing steps and achieving superior tactile and visual effects.
Solution Approach 2:
The invention adds the third dimension (height/relief) to the woodgrain pattern by using embossing instead of flat printing. This creates actual raised surfaces that provide both visual depth and tactile feedback, transforming a two-dimensional print into a three-dimensional textured surface.

AI summary
Provided is an inexpensive raised woodgrain finish decorative material that exhibits design properties similar to those of actual wood by the effect of reproducing visual appearance and feeling and has a short production timeline. The raised woodgrain finish decorative material has a substrate, a first raised section provided on one surface of the substrate, and a second raised section provided on the one surface of the substrate in a different location than the location of the first raised section, wherein the length of the first raised section is longer than the length of the second raised section in the lengthwise direction of the substrate, and the height of the first raised section is higher than the height of the second raised section in the thickness direction of the substrate.
