Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative technologies for fiber base materials lack the ability to create a three-dimensional effect that enhances both visual and tactile experiences, limiting design freedom and variation in products such as seats and other surfaces.
Innovation Solution
A decorative sheet featuring a fiber base material with a first pattern formed by resin projections of varying heights and a second pattern with gradations in lightness, hue, and chroma, applied using an inkjet recording method to create a multi-dimensional design that engages both sight and touch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a flat printed pattern is used on fiber base material, then manufacturing is simple and cost-effective, but three-dimensional visual and tactile effects are lacking
Solution Approach 1:
The invention transitions from two-dimensional flat printing to three-dimensional relief patterns by forming resin projections of varying heights on the fiber base material surface. This dimensional change creates both visual depth and tactile variation, resolving the contradiction between simplicity and three-dimensional effect.
Solution Approach 2:
The invention combines fiber base material with resin projections to create a composite structure. The resin portion forms raised patterns on the fiber substrate, enabling three-dimensional effects while maintaining the benefits of the original fiber material, thus achieving complexity without sacrificing material advantages.
2Shape
If resin projections of varying heights are formed on the fiber base material, then three-dimensional visual and tactile effects are enhanced, but manufacturing complexity increases
Solution Approach 1:
The invention replaces complex mechanical embossing or molding processes with a printing-based approach. By using print data to control resin deposition, the system achieves varied height projections through a simpler, more flexible manufacturing process that maintains ease of production while creating complex surface textures.
3Adaptability or versatility
If inkjet printing is used to create the pattern, then design flexibility and variation are increased, but manufacturing precision requirements increase
Solution Approach 1:
The invention controls resin projection height by varying printing parameters such as ink volume, number of passes, and drying conditions. This parameter-based control enables precise height variation across different pattern areas while maintaining design flexibility, resolving the contradiction between adaptability and precision requirements.
