Perforated Absorbent Package with Elastic Recovery for Scent Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to determine the scent of scented absorbent articles before purchase or opening the package, as wrapped absorbent articles are typically enclosed in bags that prevent scent detection.
Innovation Solution
A package design featuring wrapped absorbent articles with a perforated bag allowing scent access through apertures and a perfume indicator, enabling users to check the scent by compressing the package, which returns to its original shape after release, ensuring compressibility and compression resilience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wrapped absorbent articles are enclosed in sealed bags, then the articles are protected from contamination and maintained freshness, but users cannot detect the scent before purchase
Solution Approach 1:
The bag is made with apertures (perforations) that allow scent molecules to pass through while maintaining the protective enclosure. This porous structure enables users to detect the perfume scent of the absorbent articles through the bag without opening it, resolving the contradiction between protection and scent detection.
Solution Approach 2:
The apertures act as an intermediary structure that mediates between the need for sealed protection and the need for scent detection. The perforated bag allows selective passage of scent molecules while maintaining the protective barrier function.
2Loss of information
If the bag is made with apertures for scent detection, then users can check the perfume, but the bag structure becomes more complex
Solution Approach 1:
The bag is segmented with multiple small apertures distributed across its surface. This segmentation approach allows scent detection functionality to be integrated into the bag structure without requiring complex mechanisms - simply by creating numerous small openings throughout the bag material.
3Loss of information
If the package is compressed to release scent through apertures, then scent detection is enabled, but the package must maintain structural resilience
Solution Approach 1:
The package structure is designed with specific compressibility parameters (10-50% compression under 1.96N load) and recovery characteristics (90-95% resilience after 10 seconds). These parameter specifications ensure the package can be compressed enough to release scent through the apertures while maintaining structural integrity and returning to its original shape.
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
Enables users to reliably assess the scent of absorbent articles prior to purchase or opening, enhancing decision-making and user experience by allowing scent detection without opening the package.
Implementation Method 1
apertures through which the perfume of the wrapped absorbent articles contained in the bag can be pass
Implementation Method 2
a compression resilience of the package is 95% or more after ten seconds has passed after removal of the load

AI summary
A package comprises: wrapped absorbent articles comprising: an absorbent article having an absorber; and a wrapper for individually wrapping the absorbent article, the absorbent article being placed on the wrapper and folded together with the wrapper, and the absorbent article being wrapped individually by the wrapper; and a bag containing the plurality of wrapped absorbent articles, wherein the wrapped absorbent articles are provided with a perfume, at least one surface of the bag comprises: aperture through which the perfume of the wrapped absorbent articles contained in the bag can pass; and a perfume indicator for indicating an existence of the perfume, a compressibility of the package is 10% or more when a load of 1.35 kg in weight is applied in an area of 100 mm×200 mm of the package for ten seconds, and a compression resilience of the package is 95% or more after ten seconds has passed after removal of the load.
