Wearable Article Graphics Using Extracted Backsheet Materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wearable articles, such as diapers, often lack coordinated and integrated graphics on both the main body and belt, which affects their appearance and user acceptance, especially for incontinent individuals, and the production of graphics on nonwoven belts is costly due to ink rub-off issues.
Innovation Solution
A wearable article design featuring a continuous main body with seamed front and back regions, utilizing colored elastic strands or adhesives for graphics on the belt, ensuring an underwear-like appearance without compromising fit, wearability, or performance, and using different materials for the graphics to avoid production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If printing graphics on nonwoven belt material is used, then coordinated graphics on main body and belt are achieved, but production cost increases significantly due to ink rub-off issues
Solution Approach 1:
The patent extracts the graphic application from the nonwoven belt material and relocates it to the water impermeable backsheet layer. This separation allows the belt to maintain its functional nonwoven structure while the graphics are applied only to the backsheet, avoiding the ink rub-off issues associated with printing on nonwoven material.
Solution Approach 2:
The patent uses the water impermeable backsheet as a substrate to create a visual copy or representation of graphics that appears coordinated with the belt design. The backsheet serves as a canvas for applying graphics that visually complement the belt without requiring actual printing on the belt material itself.
2Ease of manufacture
If belt-type structure is used, then breathability and manufacturing economy are improved, but integrated graphic appearance is compromised
Solution Approach 1:
The patent merges the graphic application function with the water impermeable backsheet layer, combining two functions (liquid barrier and graphic substrate) into a single integrated component. This allows the belt-type structure to maintain its manufacturing advantages while achieving coordinated graphics through the backsheet rather than requiring separate graphic application processes.
3Ease of manufacture
If graphics are printed only on main body, then production cost is reduced, but coordinated appearance between main body and belt is lost
Solution Approach 1:
The water impermeable backsheet serves multiple functions: it provides liquid barrier protection, serves as a substrate for graphic application, and contributes to the overall coordinated appearance of the absorbent article. By making the backsheet multi-functional, the patent achieves coordinated graphics without adding separate components or increasing production complexity.
