Disposable Diaper Odor Elimination Printed Sheet Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable diapers are ineffective in eliminating odor after use, as current deodorant techniques do not adequately address the strong excretion odor issue, leading to discomfort and poor odor control during storage and disposal.
Innovation Solution
A disposable diaper design featuring a liquid pervious face sheet, a liquid impervious sheet, an absorbent body between the sheets, and an odor eliminating printed sheet positioned on the liquid impervious sheet opposite the absorbent body, with the after-treatment tape overlapping the odor eliminating sheet to enhance odor capture and elimination during disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a deodorant sheet containing zeolite is arranged on the inside of a top sheet, then odor elimination is attempted, but the odor elimination effect is insufficient
Solution Approach 1:
The deodorant function is segmented into multiple locations: inside the top sheet (deodorant sheet), on the body part (deodorant coating), and at the disposal end (odor eliminating printed sheet). This segmentation allows each location to address odor at different stages, improving overall effectiveness.
Solution Approach 2:
The deodorant sheet is arranged inside the top sheet in advance, and the deodorant coating is applied to the body part before use. The odor eliminating printed sheet is positioned at the disposal end to act immediately when odor is generated during storage and disposal.
2Object-affected harmful factors
If a crepe paper sheet covering an absorbent body is configured to contain a deodorant, then odor control is attempted, but the odor elimination effect remains insufficient
Solution Approach 1:
The deodorant function is divided across multiple components: the absorbent body contains some deodorant, the body part has deodorant coating, and the odor eliminating printed sheet provides additional deodorant capacity. This distributed segmentation increases overall odor elimination reliability.
Solution Approach 2:
The patent combines multiple deodorant-containing components into a single integrated system. The odor eliminating printed sheet is merged with the body part and positioned to overlap the absorbent body, creating a combined deodorant system that addresses odor more effectively than any single component alone.
3Object-affected harmful factors
If the odor eliminating printed sheet is arranged on the entire external surface of the diaper, then odor elimination coverage is maximized, but manufacturing cost increases
Solution Approach 1:
Instead of uniform deodorant distribution, the patent applies deodorant locally at critical locations: inside the top sheet, on the body part, and at the disposal end where odor is most likely to escape. This local quality approach reduces material usage and manufacturing cost while maintaining effective odor elimination.
Solution Approach 2:
The odor eliminating printed sheet is arranged to overlap the absorbent body rather than covering the entire external surface. This partial action approach provides sufficient odor elimination coverage at the critical disposal end while reducing material consumption and manufacturing cost.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The configuration effectively eliminates odor both inside and outside the diaper, providing improved odor control without the need for extensive deodorant coverage, resulting in enhanced user comfort and reduced storage container odors.

AI summary
[Problem] To provide a disposable diaper more effective in odor eliminating. [Means for Solving Problem] The above problem is solved by a disposable diaper, comprising a liquid pervious face sheet 30, a liquid impervious sheet 11, an absorbent body 56 interposed therebetween, an outer sheet 12 covering a back surface of the liquid impervious sheet 11, an after-treatment tape on an external surface of a back body part B and an odor eliminating printed sheet 25 interposed between the liquid impervious sheet 11 and the outer sheet 12 in the body part B having the after-treatment tape and formed by printing with ink a sheet base material.
