Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional nail art technologies are used, then the printing process is simple, but the selection range of materials and designs is limited

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The nail art apparatus integrates multiple functions including 3D nail measurement, image processing, touchscreen design selection, printing, and curing in a single device. This multi-functional integration expands the selection range of materials and designs while managing complexity through unified system design

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

Solution Approach 2:

The patent introduces a touchscreen as an intermediary interface between the user and the printing system, allowing selection of various designs and materials without directly complicating the mechanical printing components. The touchscreen mediates between user preferences and the physical printing process

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If manual nail art processes are used, then the apparatus is simple, but the precision and accuracy of nail region identification is low

Engineering Contradiction:
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces manual visual inspection and manual drawing with an automated image processing system that uses cameras and software algorithms to identify nail regions and transfer designs. This substitution of mechanical/manual processes with automated optical and computational systems significantly improves measurement precision

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates digital copies of the nail regions through image capture and processing, allowing for precise identification and measurement without physical contact. The digital copy enables accurate positioning and design transfer while simplifying the overall process

Inventive Principle:
Principle #26Copying

3Productivity

If automated printing is implemented, then productivity increases, but the device complexity increases

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the measurement, design selection, and printing functions into an integrated automated system. By combining these previously separate processes into one unified apparatus, productivity increases while the complexity is managed through functional integration rather than separate components

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An invention related to a nail art apparatus and a nail art method using the same is disclosed. The disclosed nail art apparatus comprises: a nail measurement device for measuring the shape of a nail input through a hand input opening formed on the front surface of a main body; a touchscreen for displaying the shape of the nail measured by the nail measurement device, displaying a nail design and color desired by a user, and inputting information about the nail design and color; a printer for printing a nail design and color according to the shape of the nail measured by the nail measurement device; a sticker supplier for supplying a nail sticker selected by the user through the touchscreen; an artificial nail supplier for supplying an artificial nail selected by the user through the touchscreen; a payment module for receiving payment for the cost of nail art; and a controller for controlling the constituent devices. In a nail art method using same, image processing technology is used to distinguish a nail area on the basis of a hand image taken by a three-dimensional nail measurement device, and a nail art image selected by the user is directly printed on the user's nail or printed on an artificial nail so as to be attached to the nail.
