Solution Overview

Problem

There is a need for containers that efficiently allow access to and carry trash bags in the janitorial industry, with existing solutions failing to provide quick and easy access while also being securely attachable to janitorial carts.

Innovation Solution

A container design featuring a rectangular prism first compartment with a pivotable side wall for access, a triangular prism second compartment for easy dispensing, and straps with buckle clips for secure attachment to janitorial carts, allowing for efficient carrying and dispensing of trash bags.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a container is designed with multiple compartments for carrying trash bags, then the functionality and organization are improved, but the device complexity increases

Engineering Contradiction:
ImprovefunctionalityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The container is divided into multiple compartments (first compartment for trash bags, second compartment for additional storage) to organize different items separately. This segmentation improves functionality by allowing janitors to carry multiple types of supplies in one container while maintaining a manageable structure through clear spatial division.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a side wall is made pivotable for quick access to trash bags, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improveaccess to trash bagsVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The first side wall is designed to be pivotable rather than fixed, allowing it to rotate open for quick access to trash bags in the first compartment. This dynamic element enables janitors to rapidly retrieve trash bags without opening the entire container, improving operational efficiency while the pivot mechanism remains a simple, low-complexity joint.

Inventive Principle:
Principle #15Dynamics

3Reliability

If straps with buckle clips are added to attach the container to a janitorial cart, then the reliability of attachment is improved, but the device complexity increases

Engineering Contradiction:
Improveattachment to janitorial cartVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Straps with buckle clips are pre-attached to the container, allowing for quick and secure connection to a janitorial cart before use. This preliminary preparation ensures reliable attachment without requiring complex assembly during operation, and the strap-buckle mechanism remains a simple, proven design that adds minimal complexity.

Inventive Principle:
Principle #10Preliminary action

AI summary

The disclosure provides a container for carrying trash bags. The container includes a first compartment in a rectangular prism having a top wall and a first side wall operable to open and close for access to the first compartment. The container also includes a second compartment in a triangular prism and secured to the first compartment. The second compartment includes first and second side walls connected to the top wall of the first compartment on bottom edges of the first and second side walls and an opening operable for access to the second compartment. The container may also include a first strap coupled to a second portion of a buckle clip and a second strap coupled to a second portion of the buckle clip and operable to secure to the first portion of the buckle clip. The first and second straps and the buckle clip are operable to attach the container to a janitorial cart.
