Solution Overview

Problem

Existing personal care products lack a combined dispenser for both dipstick and roll-on applicators in a single unit, limiting user flexibility and convenience.

Innovation Solution

A dual dispensing device with a lower body, nested cap assembly, and interchangeable dipstick and spherical ball for applying liquid personal care compositions, allowing both dabbing and rolling application methods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single dispenser unit provides both dipstick and roll-on applicators, then user flexibility and convenience are enhanced, but device complexity increases

Engineering Contradiction:

Improveapplication method flexibilityVSAvoiddispenser structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The dipstick applicator is nested within the lower cap assembly, while the roll-on applicator is nested within the upper cap assembly. Both applicators are contained within the single dispenser body, allowing users to access either type of applicator without requiring separate dispensers. This nesting arrangement provides dual application methods while maintaining a compact, integrated structure.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The dispenser unit is designed to provide multiple functions through a single device. The lower cap assembly with dipstick offers one application method, while the upper cap assembly with roll-on applicator offers another. This multi-functionality allows users to choose their preferred application method without needing separate products, thereby enhancing versatility without requiring multiple separate dispensers.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If dual applicator types are integrated into one unit, then product application options increase, but manufacturing complexity increases

Engineering Contradiction:

Improveapplicator type optionsVSAvoidassembly process complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The dispenser is divided into distinct modular components: a lower cap assembly containing the dipstick applicator and an upper cap assembly containing the roll-on applicator. Each cap assembly can be manufactured and assembled separately, then integrated into the final dispenser unit. This segmentation simplifies the manufacturing process by allowing specialized production of each sub-assembly before final integration, reducing overall manufacturing complexity despite the dual-functionality requirement.

Inventive Principle:

Principle #1Segmentation

AI summary

Disclosed herein is a packaging system for dispensing a personal care product such as a perfume. The packaging system has dual dispensing option of a dipstick and a roll-on dispenser in a single unit. The packaging system includes a reservoir, a lower cap, and an upper cap. The lower cap has a dipstick that is wetted in the reservoir. The lower cap can be unscrewed from the reservoir to expose the dipstick for use in dabbing a personal care product on skin. The lower cap also has a spherical ball that is exposed when the upper cap is unscrewed from the lower cap while the lower cap remains engaged with the reservoir section. When the packaging system is turned on its side or upside down, the liquid personal care product wets the spherical ball, and the ball can be used for roll-on application of the personal care product.
