Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for expressing the 'sense of sparkle' on a product surface can only be virtually generated after coating, requiring observation and input of size and number of luminous points, limiting their applicability.
Innovation Solution
An image processing technique that uses information about the coating material, such as flake size and layer thickness, to generate image data representing luminous points before coating, allowing for virtual expression of the sense of sparkle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If sense of sparkle is expressed based on observed luminous point information (size and number), then the sparkle effect can be virtually generated, but the technique can only be applied after coating is performed
Solution Approach 1:
The patent performs preliminary calculation of luminous point characteristics (size and number) based on coating material information before coating is applied. By calculating the expected sparkle effect in advance using the coating material's flake properties, the system enables pre-coating evaluation and selection, eliminating the need to wait until after coating to assess the sparkle effect.
2Measurement precision
If post-coating observation is required to obtain luminous point information, then accurate sparkle data can be obtained, but the process becomes inefficient and requires physical coating first
Solution Approach 1:
The patent creates a virtual model (copy) of the sparkle effect by calculating luminous point characteristics from coating material information. Instead of requiring physical coating and observation, the system generates image data representing the expected sparkle effect, allowing multiple design iterations without physical coating, thus improving productivity while maintaining sufficient accuracy for design decisions.
3Reliability
If physical coating is performed to observe luminous points, then real sparkle effect can be evaluated, but material consumption and rework increase
Solution Approach 1:
The patent creates virtual images representing the sparkle effect based on coating material information, allowing evaluation of the sparkle effect without physical coating. This virtual copying approach enables accurate assessment of different coating materials and applications before actual coating, eliminating material consumption associated with test coatings and reducing waste from incorrect applications.
