Foldable Diaper Disposal Bag with Nested Pockets to Trap Odors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current diaper disposal systems often fail to effectively block odors and provide a sanitary surface during diaper changes, posing challenges in maintaining cleanliness and preventing the spread of germs.
Innovation Solution
A foldable diaper changing and disposal bag made of plastic, featuring a front pocket for the dirty diaper and a rear pocket for securing it, which can be twisted and rolled up to create multiple layers of protection, locking in germs and odors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple disposable bag is used for diaper disposal, then cost-effectiveness is improved, but odor blocking and germ containment are insufficient
Solution Approach 1:
The patent implements a nested structure where the diaper disposal bag is placed inside a larger changing bag, which itself can be nested within additional protective layers. This multi-layer nesting approach enhances odor blocking and germ containment while maintaining cost-effectiveness through the use of simple disposable materials at each layer.
Solution Approach 2:
The disposal system is segmented into distinct functional zones: a front pocket for initial diaper containment, a main disposal area for secure storage, and a twisted closure mechanism for sealing. This segmentation allows each part to specialize in specific odor-trapping functions while using economical materials.
2Volume of moving object
If a compact disposal bag is used, then portability is improved, but the ability to provide a barrier surface during changing is reduced
Solution Approach 1:
The changing bag incorporates dynamic expandability through twist-closure mechanisms that allow the bag to transition from a compact stored state to an expanded usable state. The barrier surface can be twisted and rolled to create multiple layers of protection, providing extensive surface area when needed while maintaining a small profile when not in use.
Solution Approach 2:
The patent utilizes three-dimensional expansion by twisting and rolling the bag material to create vertical layers and depth, transforming a two-dimensional flat surface into a multi-layered three-dimensional barrier structure that provides both compact storage and extensive protection area.
3Object-affected harmful factors
If the bag is designed with multiple pockets and expansion options, then odor trapping is improved, but device complexity increases
Solution Approach 1:
The bag structure is designed with multi-functional elements where the same plastic material serves multiple purposes: it forms the barrier surface, creates odor-trapping pockets through twisting, provides structural support, and enables compact storage. This universality reduces the need for separate specialized components, maintaining simplicity while achieving effective germ containment.

AI summary
A foldable bag designed to provide a cost-effective, convenient, and sanitary way to dispose of a dirty diaper. The foldable bag comprises two pockets: a front pocket and a rear pocket. The front pocket receives the dirty diaper, while the rear pocket receives the front pocket. Once the diaper is secured in the front pocket, the user twists the front pocket to lock the odors within. Next, the user rolls up the front pocket until the front pocket reaches the top edge. Lastly, the user tucks the front pocket from the front side into the rear pocket on the rear side. Once tucked in place, the foldable bag can be properly discarded without emitting odors into the surrounding area. In a preferred embodiment, the upper section of the foldable bag folds outward to form a large surface area that can be used for changing a baby's diaper.
