Solution Overview
Problem
Existing cleaning cart systems lack versatility and flexibility in configuration, limiting their ability to adapt to various cleaning tasks and environments, and often require multiple pieces of equipment, increasing labor and chemical costs.
Innovation Solution
A modular cleaning cart system with a reservoir assembly and interchangeable modular cleaning bins that can be assembled in different configurations, featuring a U-shaped handle, wheeled chassis, and a spigot for precise fluid control, along with a specialized interlocking system for bin arrangement, allowing for customizable setups and efficient use of space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional cleaning cart systems are used, then basic cleaning functions are provided, but versatility and flexibility in configuration are limited
Solution Approach 1:
The cleaning cart system is divided into modular components including a reservoir assembly, handle assembly, and multiple interchangeable cleaning bins (mop bin, spray bin, waste bin). Each bin can be independently attached or detached from the reservoir, allowing flexible configuration based on specific cleaning needs without requiring complex integrated designs.
Solution Approach 2:
The reservoir assembly serves multiple functions by accommodating different types of cleaning bins (mop bin with wringer, spray bin with nozzle, waste bin). The universal mounting interface on the reservoir allows a single base unit to perform various cleaning tasks through bin interchangeability, enhancing versatility without increasing overall system complexity.
2Adaptability or versatility
If multiple separate pieces of equipment are used to perform different cleaning tasks, then various cleaning functions are achieved, but labor and chemical costs increase
Solution Approach 1:
Multiple cleaning functions that traditionally required separate equipment (mop storage, spray application, waste collection) are merged into a single integrated system. The reservoir assembly combines these functions by providing a unified platform that can hold different specialized bins, reducing the total number of separate equipment pieces needed.
Solution Approach 2:
The reservoir assembly acts as a universal platform that can accommodate various cleaning bins for different tasks. This multi-functionality allows a single equipment piece to replace multiple separate tools, thereby reducing equipment quantity and associated costs while maintaining diverse cleaning capabilities.
3Adaptability or versatility
If modular bins are introduced for different cleaning tasks, then versatility is improved, but device complexity increases
Solution Approach 1:
The system segments cleaning functions into separate interchangeable bins while maintaining a simple unified reservoir structure. Each bin is designed as an independent module with standardized attachment features, allowing users to mix and match bins based on needs without complicating the overall assembly process.
Solution Approach 2:
Instead of integrating multiple functions into a complex single unit, the design inverts the approach by using a simple reservoir structure with externally attachable modular bins. This reversal simplifies the base unit while maintaining versatility through optional attachments, reducing assembly complexity.

AI summary
In one embodiment, a cleaning cart system of the invention includes a reservoir assembly, an upwardly extending handle releasably connectable to the reservoir assembly, and at least two modular cleaning bins. The reservoir assembly includes a liquid reservoir and an integral wheeled chassis. The liquid reservoir includes a circumferential sidewall and an integral top wall, with the top wall including a plurality of openings. The two modular cleaning bins may be: positioned within the liquid reservoir; positioned on the liquid reservoir top wall with a leg of one bin positioned in one of the top-wall openings, and with a leg of the other bin positioned in another of the top-wall plurality of openings; and alternatively releasably interconnected to one another in a side-by-side orientation, with one of the bins supported on the upwardly extending handle by one or more of a plurality of handle brackets.
