Solution Overview

Problem

Existing laundry bags fail to adequately protect bras and facial masks from damage during washing, as their fasteners and under-wires can catch on machine components, leading to bending, breaking, or twisting, which is a significant concern due to the expense of these garments.

Innovation Solution

A washable garment case with inner fasteners, such as screw and snap connectors, and vertically positioned tracks provides structural support and secure attachment points to prevent tangling and damage, allowing for safe washing of bras and facial masks within a washing machine.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If bras and facial masks are washed directly in a washing machine, then washing convenience is improved, but the garments are damaged due to fasteners and under-wires catching on machine components

Engineering Contradiction:
Improvewashing convenienceVSAvoidgarment integrity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements a nested structure where an inner laundry bag is placed inside an outer laundry bag. The inner bag contains the delicate garments (bras and facial masks) while the outer bag provides additional protection. This nested arrangement allows the garments to be washed conveniently in the machine while being protected from damage by multiple layers of containment.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent introduces an intermediary protective layer (the inner laundry bag with fasteners) between the delicate garments and the washing machine components. This intermediary bag captures any fasteners and under-wires, preventing them from catching on machine components while still allowing the garments to be washed effectively.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If small laundry bags are used to wash delicate items, then garment protection is improved, but the bags offer little support causing garments to become twisted and damaged

Engineering Contradiction:
Improvegarment protectionVSAvoidstructural support
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses a nested dual-bag structure where the inner bag provides garment containment and the outer bag provides structural support. This nested arrangement solves the problem of the single small bag lacking support by adding an outer bag that can maintain its shape and prevent twisting while the inner bag protects the garments.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent creates a composite laundry bag system combining two separate bags with different functions. The inner bag is designed for garment containment with fastener capture capabilities, while the outer bag provides structural integrity and support. This composite structure delivers both protection and support that a single bag cannot provide.

Inventive Principle:
Principle #40Composite materials

AI summary

An improved case for washing garments including inner fasteners configured for use in releasably attaching and washing facial masks or bras or other garments to provide a practical means of securing them when tossed into a washing machine, thereby protecting their delicate materials and any fasteners and under-wires from the damage that can occur if they are placed directly into a machine.
