Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Trash cans require separate storage for trash bags, which complicates the process of replacing filled bags and prevents efficient nesting when multiple cans are stored together.

Innovation Solution

A container apparatus with an integrated receptacle for trash bags, allowing the cans to be nested while maintaining easy access to replacement bags.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a separate trash bag dispenser is attached to the trash can, then trash bag storage and replacement is improved, but the ability to nest multiple trash cans together is lost

Engineering Contradiction:

Improvetrash bag storage and replacementVSAvoidnesting capability

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent integrates the trash bag receptacle directly into the container body, merging the storage function with the container structure itself. This eliminates the need for separate external dispensers while maintaining both nesting capability and trash bag storage functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The container body is designed to serve multiple functions: it acts as both the waste receptacle and the storage container for trash bags. The integrated design allows the same structure to fulfill both waste containment and bag storage purposes, enabling nesting while providing easy access to replacement bags.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Area of stationary object

If trash bags are stored in a separate location, then storage space for the container is optimized, but additional work is required when replacing filled trash bags

Engineering Contradiction:

Improvestorage space efficiencyVSAvoidtime to replace trash bags

Core Design Contradiction:

Area of stationary objectVSLoss of time

Solution Approach 1:

The trash bags are pre-stored within the container body in an integrated receptacle, positioned for immediate access. This preliminary placement eliminates the need to retrieve bags from separate locations, reducing the time and effort required for replacement while maintaining compact storage.

Inventive Principle:

Principle #10Preliminary action

3Area of stationary object

If multiple trash cans are stored nested together, then space is saved, but access to trash bags becomes difficult

Engineering Contradiction:

Improvestorage spaceVSAvoidaccess to trash bags

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The patent designs the container with a nested structure where smaller containers can be placed within larger ones. The integrated receptacle is positioned and sized to allow access to trash bags even when nested, enabling space-saving storage while maintaining operational accessibility.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

The present disclosure provides a container apparatus. The apparatus may include a container body. The container body may include a top, a bottom, and sidewalls spanning between the top and the bottom. The bottom and sidewalls may form an interior face and an exterior face, such that an enclosure is formed by the interior face. The apparatus may further include an inner ridge and a receptacle. The inner ridge may be defined on the interior face at the bottom. The receptacle may be formed by the inner ridge. The receptacle may thus be defined on a portion of the bottom within the enclosure. The inner ridge includes a hollow interior that forms an outer channel on the exterior face. The container body may be a trash can, and the receptacle may be shaped to receive a roll of trash bags.
