Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current articles of footwear and apparel lack the ability to dynamically change their appearance in response to different viewing angles, limiting their visual interest and aesthetic appeal.
Innovation Solution
Integration of a multi-layered lenticular lens structure combined with a discrete coloring element, where the lenticular lens structure is printed and cured onto a base material element, creating a dynamic optical effect by altering the apparent color and appearance when viewed from various angles.

Engineering Contradiction Analysis
1Ease of manufacture
If a multi-layered lenticular lens structure is integrated with a discrete coloring element, then the visual appeal and aesthetic value are enhanced through dynamic optical effects, but the device complexity and manufacturing complexity increase
Solution Approach 1:
The patent combines the lenticular lens structure and discrete coloring element into a single integrated optical structure. The lens structure is formed directly over the coloring element in a unified manufacturing process, eliminating the need for separate assembly steps and reducing overall device complexity while maintaining the dynamic optical effects.
Solution Approach 2:
The optical structure is divided into distinct functional layers: the base coloring element layer and the overlying lenticular lens layers. This segmentation allows each layer to be optimized and manufactured independently using standard printing and curing processes, then integrated together, simplifying the overall manufacturing complexity.
2Manufacturing precision
If multiple lens layers are used to create dynamic optical effects, then the visual appeal is enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The discrete coloring element is printed and cured onto the base material element before the lenticular lens structure is formed over it. This preliminary action establishes a stable foundation that guides subsequent lens layer formation, reducing the precision requirements for aligning multiple layers during manufacturing.
Solution Approach 2:
The discrete coloring element serves as an intermediary layer between the base material and the lenticular lens structure. This intermediary provides a stable reference surface that facilitates the formation of the lens layers above it, reducing the overall manufacturing precision requirements for the multi-layer structure.
