Solution Overview

Problem

Existing sport attires often require significant undressing for bathroom access, which is cumbersome and time-consuming, especially in competitive sports, while also lacking adequate support and privacy.

Innovation Solution

A garment design featuring an anterior and posterior torso portion forming an upper covering, and an anterior and posterior pelvic portion forming a lower covering, with an extendible region in the posterior pelvic portion that transitions between raised and lowered positions to create an accessible opening for the wearer's pelvic area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the garment is designed to provide full coverage and support, then modesty and support are improved, but accessibility to the lower body deteriorates

Engineering Contradiction:
Improvemodesty and supportVSAvoidaccessibility to lower body
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The garment is divided into separate upper and lower portions that can be independently positioned. The lower portion can be pulled down to create an opening for bathroom access while the upper portion remains in place, providing segmentation that enables both coverage and accessibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The garment transitions from a static full-coverage design to a dynamic configuration where the lower portion can be moved between covering and exposed positions. This dynamic adjustment allows the wearer to maintain modesty during activities and easily access the lower body when needed.

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If the garment requires significant undressing for bathroom access, then full coverage is maintained, but time consumption and convenience deteriorate

Engineering Contradiction:
Improvefull coverageVSAvoidtime for bathroom access
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The garment is segmented into upper and lower portions that can be independently manipulated. The lower portion can be quickly pulled down for bathroom access and returned to its original position, eliminating the need for complete undressing and significantly reducing time consumption.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The garment is pre-configured with a lower portion that can be easily displaced. This preliminary design allows the wearer to quickly access the bathroom by simply pulling down the lower portion without needing to undress completely, saving time during bathroom breaks.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the extendible region is extended to create an opening, then accessibility is improved, but coverage and modesty deteriorate

Engineering Contradiction:
ImproveaccessibilityVSAvoidcoverage and modesty
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The lower portion of the garment is designed to be dynamically positionable between covering and exposed states. When extended, it creates an opening for accessibility; when returned to its original position, it restores full coverage and modesty, allowing the wearer to control the balance between accessibility and coverage as needed.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Facilitates easy access to the lower body without removing the garment, providing support, coverage, and modesty, while allowing for a range of motion during activities.

Implementation Method 1

the posterior pelvic portion comprise an extendible region, the extendible region configured to extend when the posterior pelvic portion is pulled, the extendible region extending from: a raised position for securing the posterior pelvic portion to the wearer to conceal the wearer's back pelvic area, to a lowered position to reveal the wearer's pelvic area, and returnable to said raised position

AI summary

Garments with accessible openings are provided, the accessible openings defined between a back torso portion and a back pelvic portion of the garment. When worn on a body, the back pelvic portion has an extendible pelvic region that can transition into a lowered state, which creates or widens a gap between the back torso and back pelvic portions to form the accessible opening for the wearer.
