Solution Overview

Problem

Conventional Japanese dresses often come loose and are difficult to wear due to their design, which includes a wide neckband and overlap that can cause discomfort and require external assistance for adjustment.

Innovation Solution

A full-length Japanese dress design where the upper and lower body are three-dimensionally sewn without an overlap, incorporating strings that allow for adjustable tying to secure the dress without tightness, featuring a narrow neckband and optional sleeves for various occasions, enabling easy wear and a comfortable, balanced fit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wide neckband is used in conventional Japanese dresses, then the dress can be worn by providing structural support, but the neckband hides accessories and may hide the neck itself, reducing aesthetic flexibility

Engineering Contradiction:
Improvestructural supportVSAvoidaesthetic flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent removes the wide neckband structure from the dress design. Instead of using a wide neckband for structural support, the dress employs a different construction method where the collar and upper chest area are shaped to provide support without the bulk of a wide neckband, thereby allowing accessories and neck visibility while maintaining structural integrity.

Inventive Principle:
Principle #2Taking out (Extraction)

2Shape

If an overlap is included in the dress design, then the dress can be structured to fit the body, but the overlap creates a thick appearance around the belly and requires external assistance for adjustment

Engineering Contradiction:
Improvebody fitVSAvoidease of wearing
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The patent eliminates the overlap structure from the dress design. The dress is constructed without overlapping panels at the front, instead using a flat front design that avoids the thick appearance around the belly. The fit is achieved through three-dimensional sewing and strategic placement of strings for adjustment, allowing the wearer to secure the dress independently.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The dress incorporates multiple strings (first string from upper side of waist line on lower front right side, second string from lower side of waist line on upper front reverse side, third string from lower side of waist line on lower front reverse side, fourth string from upper side of waist line on left side, fifth string from region inside right side open end, sixth string from region along left side sewing line) that enable the wearer to adjust and secure the dress independently without requiring external assistance from a fitter or beauty salon professional.

Inventive Principle:
Principle #25Self-service

3Reliability

If the dress is fixed by winding waist cords around the body, then the dress can be secured to the wearer, but the wearer experiences a sense of tightness and discomfort

Engineering Contradiction:
Improvedress securityVSAvoidcomfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent divides the fastening function into multiple separate strings positioned at different locations on the dress (first string at upper side of waist line on lower front right side, second string at lower side of waist line on upper front reverse side, third string at lower side of waist line on lower front reverse side, fourth string at upper side of waist line on left side, fifth string at region inside right side open end, sixth string at region along left side sewing line). This segmentation allows for distributed, adjustable fastening that secures the dress without concentrating tightness in one location, thereby improving comfort while maintaining security.

Inventive Principle:
Principle #1Segmentation
