3D Outsole Dye Permeation for Durable Pattern Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming patterns on shoe outsoles, such as attaching films or applying paint, result in patterns that can peel off or degrade over time, affecting aesthetics and durability.
Innovation Solution
A method involving dye permeation into micropores on the inner or outer surface of a three-dimensional outsole, fixed through vacuum suction, ensuring the pattern is integrated and durable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a film is attached or paint is applied to form a pattern on the outsole, then the pattern can be formed on the surface, but the pattern may be peeled off or worn off over time, degrading durability
Solution Approach 1:
The outsole surface is designed with micropores that allow dye to penetrate and embed within the material structure. This porous structure enables the pattern to be integrated into the outsole rather than merely surface-applied, significantly improving durability and preventing peeling or wear off over time.
Solution Approach 2:
The pattern formation process merges the dye application with the outsole material itself by allowing dye penetration into micropores. This combining of the pattern layer with the base material eliminates the interface between separate layers, preventing peeling and ensuring long-term retention.
2Shape
If a film is attached or paint is applied to form a pattern on the outsole, then a pattern can be formed, but a beautiful pattern is not formed, degrading aesthetics
Solution Approach 1:
The microporous structure of the outsole enables uniform dye penetration and distribution, creating a beautiful and consistent pattern appearance. The porous material allows the dye to settle evenly within the microstructure, enhancing aesthetic quality while maintaining durability.
3Reliability
If dye is permeated into micropores to fix the pattern, then pattern durability is improved, but the process requires vacuum suction and specific penetration depth control, increasing process complexity
Solution Approach 1:
A vacuum suction system is employed to facilitate dye penetration into the micropores of the outsole. The vacuum creates negative pressure that draws the dye into the porous structure, ensuring uniform and controlled penetration to the required depth while simplifying the fixation process.
Solution Approach 2:
The penetration depth of the dye is controlled as a critical parameter, optimized to range from 0.08 mm to 0.12 mm. This parameter control ensures sufficient durability while managing the complexity of the vacuum suction process by establishing a specific target depth for effective pattern fixation.
