Wearable Article Artwork Visual Integrity via Local Opacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable articles with printed artwork face challenges in providing an integral appearance due to structural differences between the main body, elastic belt, and transitional regions, while also needing to maintain performance as absorbent articles.
Innovation Solution
A wearable article design featuring a main body and a ring-like elastic belt with front and back belts, where the belt artwork regions are printed on the backsheet and the crotch artwork region, ensuring visual integrity by managing opacity and contrast differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If belt-type pants with separate elastic belt and main body are used, then breathability and manufacturing economy are improved, but visual integrity of printed artwork deteriorates due to structural differences between regions
Solution Approach 1:
The patent applies local quality by making the outer cover layer opaque specifically in the belt artwork regions where it overlaps with the elastic belt, while keeping it transparent in the crotch artwork region. This localized modification allows the artwork to appear visually integrated across different structural regions without compromising the breathability and manufacturing advantages of the belt-type construction.
2Manufacturing precision
If outer cover layer is made opaque to improve artwork visibility, then artwork quality is improved, but breathability and comfort deteriorate
Solution Approach 1:
The outer cover layer is designed with spatially varying optical properties: opaque in belt artwork regions to ensure visibility through the elastic belt, and transparent in the crotch region to maintain breathability and comfort. This localized differentiation resolves the contradiction between artwork visibility and breathability.
3Adaptability or versatility
If belt artwork region and crotch artwork region are printed separately, then manufacturing flexibility is improved, but overall artwork quality deteriorates due to lack of visual integration
Solution Approach 1:
The patent employs color and opacity changes in the outer cover layer to achieve visual integration of separately printed artwork. By making the outer cover layer opaque in specific regions, the separately printed belt artwork and crotch artwork appear as a unified design, resolving the contradiction between manufacturing flexibility and overall artwork quality.

AI summary
Disclosed is a wearable article comprising a main body and a ring-like elastic belt comprising an outer cover layer, a backsheet, a front belt artwork region; and a back belt artwork region; and wherein one or both of the front and back belt artwork regions comprises a belt artwork; a transitional region on the front waist panel and the back waist panel where the outer cover layer exists; and a crotch artwork region on the crotch panel comprising a crotch artwork; wherein at least some of the belt artwork and some of the crotch artwork are printed on the backsheet, wherein when the opacity of the outer cover layer is OC and the opacity of one or both of the front belt and the back belt comprising the belt artwork is OB, respectively, the difference between OC and OB is less than about 20%.
