Solution Overview

Problem

Existing nail technologies, such as acrylic nails and nail extensions, do not allow for easy and frequent changes in aesthetic appearance without requiring significant time and effort, and press-on nails do not endure as long as desired.

Innovation Solution

A nail system comprising a detachable nail component and a base component that can be easily interchanged, allowing for quick changes in aesthetic appearance by attaching or detaching the nail component from the base component, which remains attached to the nail plate, using mechanisms like tension locking, interlocking channels, and adhesive systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If acrylic nails or nail extensions are used to provide durable aesthetic appearance, then the duration of aesthetic presentation is improved, but the ease of changing appearance deteriorates as they require significant time and effort to alter

Engineering Contradiction:
Improveduration of aesthetic appearanceVSAvoidease of changing appearance
Core Design Contradiction:
Duration of action of stationary objectVSEase of operation

Solution Approach 1:

The nail system is divided into separate components: a base component that attaches to the natural nail plate and remains in place, and interchangeable nail components that can be easily attached and detached from the base. This segmentation allows the base to provide durable attachment while the interchangeable nail components enable easy appearance changes without removing the entire nail system.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If press-on nails are used to enable easier removal and replacement, then the ease of operation is improved, but the reliability deteriorates as they do not endure as long as artificial nails and extensions

Engineering Contradiction:
Improveease of removal and replacementVSAvoiddurability of attachment
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The invention merges the advantages of press-on nails (easy removal) with the durability of acrylic nails by combining a securely attached base component with interchangeable nail components. The base component provides reliable attachment to the nail plate using adhesive or mechanical means, while the nail components can be easily attached and detached, achieving both ease of operation and reliability simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

3Duration of action of stationary object

If traditional nail extensions are used to provide long-lasting aesthetic appearance, then the duration of action is improved, but the loss of time increases when changes are desired

Engineering Contradiction:
Improveduration of aesthetic appearanceVSAvoidtime required for appearance changes
Core Design Contradiction:
Duration of action of stationary objectVSLoss of time

Solution Approach 1:

The base component is pre-attached to the natural nail plate and remains in place throughout use. This preliminary action of securing the base allows for rapid interchange of nail components without requiring removal and reapplication of the entire nail system, significantly reducing the time required for appearance changes while maintaining long-lasting attachment.

Inventive Principle:
Principle #10Preliminary action

AI summary

A nail system includes a nail component; and a base component. The nail component is configured to attach to the base component, and the base component is configured to attach to a nail plate of a person's digit. The nail component has an upper, outer nail surface that is configured to cover a nail plate and the base component for providing a desired aesthetic presentation of the digit when the nail component is attached to the base component and the base component is attached to the nail plate. In some embodiments, the nail component is configured to detach from the base component for use of another nail component with the base component. The nail component preferably is configured to detach from the base component while the base component is attached to the nail plate for interchanging the nail component with another nail component having a different aesthetic appearance.
