Lace Tip Light Refraction via Layered Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lace tips lack the ability to generate visual changes based on the user's view angle, as the patterns are permanently formed and do not effectively utilize light refraction to create apparent vision changes, and the transparent bodies often peel off due to rubbing, failing to enhance promotion and impression.
Innovation Solution
A method involving a sequence of glue, pattern, and transparent layers on a lace body, where the pattern layer has alternating first and second portions, and the transparent layer features concave and convex portions that refract light as the user changes their view angle, creating color and pattern variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a transparent body is used to enclose a pattern on the lace tip, then light refraction can create visual effects, but the transparent body is likely to peel off from the transparent layer due to rubbing during usage
Solution Approach 1:
The patent merges the transparent body and pattern layer into a single integrated structure where the pattern layer is formed directly on the transparent layer without a separate transparent body enclosing it. This integration eliminates the interface between the transparent body and transparent layer, preventing peeling while maintaining light refraction effects through the patterned surface itself.
Solution Approach 2:
The patent extracts the enclosing transparent body from the traditional lace tip structure and replaces it with a pattern layer that is directly formed on the transparent layer. This removal of the separate transparent body eliminates the peeling issue while preserving the optical functions through the patterned surface.
2Stability of the object's composition
If a pattern is permanently formed on the lace body, then the pattern remains fixed, but the pattern cannot vary with the user's different sightlines and fails to enhance promotion and impression
Solution Approach 1:
The patent creates a dynamic visual effect by forming the pattern layer with specific geometric patterns (such as stripes, dots, or lines) that interact with light refraction through the transparent layer. As the user changes their viewing angle, the refraction effect causes the pattern to appear to move or change, providing visual variation while maintaining structural stability.
Solution Approach 2:
The patent utilizes light refraction through the patterned transparent layer to create color shifting effects. Different viewing angles cause different portions of the pattern to be highlighted or obscured, creating the appearance of color changes or visual variations without actually changing the physical pattern structure.
3Ease of manufacture
If the pattern on the lace tip is permanently formed, then manufacturing is simple, but the pattern cannot generate apparent vision change effects merely by refraction through a transparent body
Solution Approach 1:
The patent combines the pattern formation and refraction functions into a single integrated structure where the pattern layer is directly formed on the transparent layer. This merging eliminates the need for a separate transparent body and maintains manufacturing simplicity while enabling vision change effects through the integrated patterned surface.
Solution Approach 2:
The patent creates dynamic vision change effects by designing the pattern layer with specific geometric configurations that interact with light refraction. As users change their viewing angles, the refraction effect causes the pattern to appear to move or transform, providing visual variability without complicating the manufacturing process.

Function Achieved in This Case
The method enables lace tips to generate color changes with view angle changes, enhancing visual appeal and preventing pattern degradation by securely fixing the layers through thermal pressing.
Implementation Method 1
the concave portions or the convex portions can refract light through the first portions and the second portions in accordance with changes of user's view angle
Implementation Method 2
The glue layer, the pattern layer and the transparent layer are fixed in sequence on the predetermined location of the lace body by at least one time of thermal pressing
