Cleaning cart and cleaning system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cleaning staff often forget essential cleaning utensils or attach unnecessary ones to the trolley, leading to inefficiencies in task preparation.
Innovation Solution
A cleaning trolley equipped with a unique, machine-readable identifier, such as a QR code, that allows for identification and inventory management via a data processing device, enabling optimal equipment selection and condition monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cleaning staff manually stock the cleaning cart, then the cart can be equipped with cleaning utensils, but essential utensils may be forgotten or unnecessary utensils may be attached
Solution Approach 1:
The system uses machine-readable identifiers on cleaning carts that provide feedback to the data processing device about which cart is being stocked. The database then provides feedback information about the correct utensils to attach, creating a closed-loop system that guides cleaning staff and prevents errors in equipment selection.
Solution Approach 2:
The system enables the cleaning cart itself to 'identify' what it needs through its machine-readable identifier. The cart essentially serves itself by providing its ID to the system, which then automatically determines and communicates the required utensil configuration, reducing reliance on human memory and judgment.
2Ease of operation
If cleaning staff manually select cleaning utensils, then flexibility in equipment selection is possible, but time is lost in decision-making and preparation
Solution Approach 1:
The system performs preliminary action by pre-defining sets of cleaning utensils tailored to specific cleaning tasks in the database. When a cart is identified, the system quickly retrieves the pre-prepared list of required utensils, eliminating the need for staff to make decisions during the stocking process and significantly reducing preparation time.
Solution Approach 2:
The patent replaces the mechanical decision-making process (staff mentally selecting utensils) with an automated information system. The machine-readable identifier and database system automatically determine the correct equipment list, substituting human cognitive processes with automated data retrieval and display.
3Productivity
If cleaning carts are identified individually, then centralized inventory management is possible, but device complexity increases
Solution Approach 1:
The machine-readable identifier serves multiple functions: it uniquely identifies the cleaning cart, links to the cart's configuration requirements, and enables centralized tracking. This universal identifier system consolidates what would otherwise require multiple separate systems, managing complexity while enabling comprehensive inventory management.
