Solution Overview

Problem

Conventional nail print apparatuses become large, heavy, and costly when designed to print on multiple fingers with varying nail lengths, particularly due to the need for a large printable range to accommodate the thumb and other fingers.

Innovation Solution

A nail print apparatus with a grabbing section that includes a first finger positioning section for four fingers and a second finger positioning section for the thumb, misaligned to align the nails of the thumb and other fingers in the same position, allowing for printing without requiring a large print area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the printable range of the printing section is enlarged to accommodate nails of all fingers with different lengths, then all fingers can be printed, but the apparatus becomes larger, heavier and more costly

Engineering Contradiction:

Improveability to print on all fingersVSAvoidapparatus weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of stationary object

Solution Approach 1:

The finger positioning mechanism is divided into multiple independent positioning sections (first finger positioning section and second finger positioning section) that can be adjusted separately. This allows the apparatus to accommodate fingers of different lengths without requiring a uniformly large printing section, thereby reducing the overall apparatus size and weight while maintaining the ability to print on all fingers.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The positioning sections are designed to be movable and adjustable rather than fixed. The first and second finger positioning sections can be moved to different positions along the inserting direction to adapt to varying finger lengths. This dynamic adjustment capability allows the apparatus to maintain a compact printing section while still being able to print on nails of all finger types.

4Weight of stationary object

If the printing section is made smaller and lighter, then the apparatus becomes more compact, but it becomes difficult to print on nails of all fingers with different lengths

Engineering Contradiction:

Improveapparatus weightVSAvoidability to print on all fingers

Core Design Contradiction:

Weight of stationary objectVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Different positioning sections are provided with different characteristics suited to their specific functions. The first finger positioning section is optimized for positioning four fingers, while the second finger positioning section is optimized for positioning the thumb. This localized optimization allows each section to handle its specific finger type effectively within a compact overall apparatus design.

AI summary

Disclosed is a nail print apparatus including: a nail print apparatus including: a print finger inserting section to insert a finger with a nail to be printed as a print finger; a non-print finger inserting section to insert a finger on which printing is not performed as a non-print finger; a grabbing section which is provided between the print finger inserting section and the non-print finger inserting section and which can be pinched with the print finger and the non-print finger; and a printing section which performs printing on a nail of the print finger, wherein the grabbing section includes a first finger positioning section to position the four fingers when printing is performed by the printing section; and a second finger positioning section to position the thumb of the second hand when printing is performed by the printing section.
