Solution Overview

Problem

Conventional dispensers often lead to separation of compositions due to density differences and lack appeal to children, making them less effective for use.

Innovation Solution

A spiral-shaped or hourglass-shaped dispenser with a narrow neck and a coating to reduce friction, allowing for uniform composition flow and appealing design to encourage children's use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a conventional dispenser is used to store composition, then the composition can be stored and dispensed, but the composition tends to separate into portions of higher and lower densities

Engineering Contradiction:

Improvecomposition uniformityVSAvoidcomposition separation

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

The dispenser employs a spiral-shaped body with a curved central axis that extends from a first end to a second end. This curved geometry creates continuous mixing action as the composition moves through the spiral path, preventing density-based separation and maintaining composition uniformity throughout the internal volume.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The dispenser is designed to be rotated about a longitudinal axis that is perpendicular to a plane that includes the central axis. This rotational movement creates dynamic mixing action within the spiral body, continuously redistributing the composition and preventing separation into density layers.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If a conventional dispenser is used, then the composition can be stored, but the dispenser does not appeal to children and thus provides no incentive for children to use the composition

Engineering Contradiction:

Improvechildren's usage incentiveVSAvoidappeal to target audience

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The dispenser features an asymmetric spiral shape with a curved central axis that creates a visually engaging and unique form factor. This asymmetric design departs from conventional cylindrical or rectangular dispenser shapes, making the product more appealing to children and providing a distinctive user experience.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The spiral-shaped body can be manufactured in various colors and patterns that appeal to children. The curved surface area allows for creative color applications, designs, and visual elements that make the dispenser more attractive to the target audience while maintaining the functional spiral geometry.

Inventive Principle:

Principle #32Color changes
