Modular Cleaning Cart Layout for Touch-Free Spill Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile cleaning systems lack flexibility and fail to store necessary tools, leading to risks of unwanted contact and exposure to cleaning products, and often require post-cleanup to prevent hazards.
Innovation Solution
A modular mobile cleaning system with a push cart that includes configurable spaces for various cleaning and disinfecting modules, a tool drip tray to prevent spills, and secure storage for tools and accessories, enabling touch-free cleaning and disinfecting operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing mobile cleaning systems are used, then basic cleaning function is provided, but flexibility to accommodate various cleaning operations is lacking
Solution Approach 1:
The cleaning system is divided into separate functional modules (storage modules, cleaning tool modules, disinfecting modules) that can be independently selected and attached to the cart based on specific cleaning needs, providing versatility without requiring a complex integrated system
Solution Approach 2:
The cart is designed with universal attachment mechanisms and standardized module interfaces that allow the same base cart to support multiple different cleaning operations and tool configurations, achieving adaptability across various cleaning scenarios
2Ease of operation
If existing mobile cleaning systems are used, then cleaning operations can be performed, but necessary tools cannot be stored on-board
Solution Approach 1:
The system combines multiple storage functions (tool storage, chemical storage, waste collection) into integrated storage modules that attach to the cart, eliminating the need for separate storage units and enabling touch-free operation while maintaining operational simplicity
Solution Approach 2:
Storage modules are designed with nested compartments and hierarchical organization where smaller storage containers fit within larger modules, maximizing on-board storage capacity without increasing overall system footprint or complexity
3Reliability
If existing mobile cleaning systems are used, then cleaning products can be applied, but risks of unwanted contact and exposure exist
Solution Approach 1:
The system extracts and isolates hazardous cleaning products and tools into separate, secured storage modules with controlled access mechanisms, removing them from general access areas and reducing exposure risks while maintaining manageable system complexity
Solution Approach 2:
The design incorporates intermediary containment structures (drip trays, spill containment barriers, sealed storage compartments) between the cleaning products/tools and the user environment, providing passive safety protection without requiring complex active control systems
4Reliability
If existing mobile cleaning systems are used, then cleaning operations can be performed, but post cleanup is required to prevent hazards
Solution Approach 1:
The system incorporates preliminary hazard prevention features such as spill containment trays, drip prevention designs, and secure tool storage that are built into the structure before use, preventing hazards from occurring in the first place and eliminating the need for post-cleanup hazard remediation
Solution Approach 2:
The design includes self-contained waste collection modules and automatic drip collection systems that manage hazards automatically during and after cleaning operations without requiring additional manual intervention or post-cleanup activities

AI summary
A mobile cleaning system (10) that enables touch-free, daily cleaning and disinfecting to areas or locations within an establishment is provided. The system includes generally a push cart (12) having front (18) and rear (20) sections spaced between vertically upstanding side sections (22A-B). One or more sections of the cart (12) include a modulated space configurable with one or more cleaning and/or disinfecting modules for performing and supporting a cleaning and/or disinfecting operation. A tool drip tray (30) extends outward from at least one of the sections beneath a tool storage location (32A-B) for preventing liquid or debris from dropping onto a surface beneath the cart (12) while stationary or in transit.
