Natural Fiber Absorbent Package Shape Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent article packages face challenges in retaining shape after opening, leading to potential contamination and increased environmental impact due to the use of non-renewable materials.
Innovation Solution
The use of package materials comprising natural fibers that form a primary seal and a reclosable secondary closing element, allowing the package to maintain its shape and be easily resealed after opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plastic polymer film is used for packaging, then the package can withstand packaging process rigors and flexing, but the package does not retain its shape after opening and may collapse
Solution Approach 1:
The patent changes the material parameter from plastic polymer film to natural fiber-based material. This material substitution fundamentally alters the package's structural properties, enabling it to maintain shape integrity after opening while still providing sufficient strength during the packaging process. The natural fiber material's inherent rigidity and structural stability resolve the contradiction between withstanding process rigors and retaining shape.
Solution Approach 2:
The patent employs composite material construction by combining natural fibers with appropriate binders or coatings to achieve both flexibility during packaging and shape retention after opening. The composite structure allows the package to exhibit different mechanical properties at different stages: flexibility and strength during sealing and handling, then shape retention when opened and stored.
2Object-generated harmful factors
If natural fiber materials are used for packaging, then the environmental impact is reduced and renewable resources are utilized, but the package material is prone to creasing, cracking, and tearing
Solution Approach 1:
The patent modifies the physical and chemical parameters of natural fiber materials through processing treatments, such as fiber length optimization, density control, and surface treatment. These parameter changes enhance the material's resistance to creasing, cracking, and tearing while preserving its renewable and environmentally friendly characteristics.
Solution Approach 2:
The patent creates composite materials by combining natural fibers with strengthening agents, coatings, or layered structures. This composite approach maintains the environmental benefits of natural fibers while significantly improving their mechanical strength and resistance to damage during handling and storage.
3Loss of substance
If absorbent articles are packaged in multi-packs without individual packaging, then packaging material usage is reduced, but the articles are exposed to environmental insults and potential contamination after first opening
Solution Approach 1:
The patent divides the packaging system into multiple functional layers or compartments within a single multi-pack structure. Each article or group of articles is separated by dividers or individual pouches made from the same natural fiber material, allowing the package to remain partially closed while enabling selective access to individual articles.
Solution Approach 2:
The patent incorporates a reclosable seal mechanism that allows consumers to close the package after opening it to remove one or more articles. This preliminary preparation of the reclosing function enables the package to protect remaining articles from environmental insults and contamination, addressing the issue before it occurs.
4Object-affected harmful factors
If a reclosable secondary closing element is added to the package, then articles are protected from contamination after opening, but the device complexity increases
Solution Approach 1:
The patent designs the secondary closing element to serve multiple functions: it provides contamination protection, enables reclosability, and maintains package shape. By integrating these functions into a single simple component made from the same natural fiber material, the patent minimizes the increase in device complexity while achieving the desired protection.
Solution Approach 2:
The patent uses the same natural fiber material for both the primary package structure and the secondary closing element, creating a homogeneous packaging system. This material consistency simplifies manufacturing, reduces the number of different components needed, and maintains the environmental benefits while providing the required protection function.
