Solution Overview

Problem

Current tampon applicator packaging is prone to tearing and puncturing, making it difficult to carry and use discreetly, requires multiple steps for application and disposal, and is bulky, leading to inconvenience and potential infection risks.

Innovation Solution

A tampon applicator package assembly featuring a durable cap that encloses the applicator and plunger, allowing for easy one-handed use and disposal, with a design that minimizes steps required for insertion and disposal, and disguises the product for discretion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional plastic film or paper wrappers are used for tampon packaging, then the packaging can be made lightweight and simple, but the wrappers tend to tear, break open and puncture when carried for extended periods

Engineering Contradiction:
Improvewrapper durabilityVSAvoidpackaging structure
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The packaging is divided into two functional parts: a rigid cap that provides structural strength and protection, and a flexible wrapper that provides containment and hygiene. The cap serves as a durable outer shell while the wrapper maintains product integrity, resolving the contradiction between durability and simplicity by distributing functional requirements across segmented components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The packaging combines different materials with complementary properties: a rigid material (such as plastic or metal) for the cap to provide strength and puncture resistance, and a flexible material (such as foil or plastic film) for the wrapper to provide containment. This composite structure resolves the contradiction by leveraging the strengths of each material type.

Inventive Principle:
Principle #40Composite materials

2Volume of moving object

If traditional wrappers are used, then manufacturing can be simple, but the wrappers are bulky and occupy large space when carried

Engineering Contradiction:
Improvepackaging sizeVSAvoidpackaging production
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The tampon applicator is nested within the cap, with the wrapper containing the applicator which in turn contains the tampon. This nested structure maximizes space efficiency by eliminating empty space between packaging layers, resolving the contradiction between compact size and manufacturing simplicity through hierarchical nesting of components.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Difficulty of detecting and measuring

If traditional wrappers with traditional shapes and bright colors are used, then product identification is clear, but it becomes very easy to identify tampons from a distance causing embarrassment

Engineering Contradiction:
Improveproduct detectabilityVSAvoiduser embarrassment
Core Design Contradiction:
Difficulty of detecting and measuringVSObject-affected harmful factors

Solution Approach 1:

The cap is designed with localized functional features (such as opening mechanisms, sealing edges, or texture variations) that provide tactile or visual cues for identification without requiring overall bright colors or traditional tampon-shaped packaging. This allows the product to remain discreet while maintaining usability through localized quality indicators.

Inventive Principle:
Principle #3Local quality

4Productivity

If traditional wrappers are used, then initial packaging is simple, but multiple steps are required to remove the tampon, position the applicator, and dispose of the used product

Engineering Contradiction:
Improveusage efficiencyVSAvoidpackaging structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The cap serves multiple functions: it acts as the outer protective packaging, the containment vessel for the applicator, and the disposal container for the used tampon. By merging these functions into a single reusable component, the system reduces the number of steps required for usage and disposal while maintaining necessary packaging functions, resolving the contradiction between efficiency and complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cap is designed as a multi-functional component that performs packaging, protection, and disposal functions throughout the product lifecycle. This universal design allows the same component to serve different purposes at different stages (new product containment during storage, protective shell during usage, and disposal container after use), improving productivity without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

5Ease of operation

If traditional wrappers are used, then initial containment is provided, but the wrappers do not tear consistently making disposal difficult and requiring alternative methods

Engineering Contradiction:
Improvedisposal convenienceVSAvoidwrapper consistency
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Instead of designing the wrapper to tear open for disposal (which creates inconsistency), the design inverts the approach by making the cap the primary disposal container. The cap remains intact throughout use and simply receives the used applicator for disposal, eliminating the need for controlled tearing and providing consistent, reliable disposal operation.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

Disclosed is a tampon applicator package assembly having a tampon applicator and a cap having a closed end and an open end. The tampon applicator has a barrel for housing a pledget and a plunger. The plunger has an end portion that is a cap cover that connects to a remainder of the plunger and mates with the cap at the open end to provide a seal with the cap that completely encloses the tampon applicator in the cap. Also disclosed is an assembly having a tampon applicator, a cap having both a closed end and open end, and a cap cover for covering the open end of the cap. When the cap cover is placed on the open end, the open end is sealed and the tampon applicator is completely enclosed in the cap.
