Cleaning cart
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning carts are difficult to use, noisy when moved, challenging to navigate through narrow openings, and prone to leaking dirt and debris onto clean surfaces.
Innovation Solution
A cleaning cart design featuring a base with a sloped floor, modular tool holders, and a gutter system that captures debris, along with adjustable bucket restraining devices and interchangeable storage options to minimize noise and prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tools are stored on the cart, then cleaning equipment is transported, but dirt and debris leak onto clean surfaces
Solution Approach 1:
The patent converts the harmful leakage of dirt and debris into a beneficial containment system. The gutter system captures debris that would otherwise leak, and the bucket restraining device with lateral and rear walls contains dirt within the storage region, transforming the problem of debris generation into an organized containment solution.
Solution Approach 2:
The patent introduces intermediary structures between the tools and the external environment. The gutter acts as an intermediary channel to collect and redirect debris, while the bucket restraining device serves as an intermediary barrier that prevents dirt from escaping the storage region onto clean surfaces.
2Ease of operation
If the cart structure is simplified, then ease of use improves, but noise when moving increases
Solution Approach 1:
The patent merges multiple functions into integrated structures. The base integrates the gutter system, storage region, and bucket restraining device into a unified structure that provides ease of use while reducing noise. The modular tool holders are combined with the base structure, creating a cohesive design that minimizes separate moving parts and associated noise.
3Area of moving object
If the storage region width is reduced, then passage through narrow openings improves, but debris containment capability worsens
Solution Approach 1:
The patent addresses the width limitation by utilizing vertical and depth dimensions. The gutter system extends along the length of the base, providing containment in the longitudinal dimension. The bucket restraining device uses lateral and rear walls to create containment in the vertical and depth dimensions, compensating for the reduced width while maintaining effective debris containment.

AI summary
Cleaning cart (10) including a base (12), a plurality of wheels (20, 22), a storage region (14) depending from the base, and a bucket restraining device (58). The base has a first side wall (28), a second side wall (26), and a front wall (30), the base having at least one portion configured to receive a bucket (56) thereon. The bucket restraining device has a lateral restraining wall (64) and a rear restraining wall (62) that cooperate to define a first restraining region (66) and a second restraining region (70). The first restraining region is defined by the first side wall, the front wall, the lateral restraining wall, and a portion of the rear restraining wall. The second restraining region is defined by the second side wall, the front wall, the lateral restraining wall, and a different portion of rear restraining wall.
