Cleaning system and method for operating a cleaning system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleaning systems, particularly in large buildings, face challenges in efficiently and effectively executing cleaning tasks due to the need for manual operation and the lack of a user-friendly interface for managing cleaning utensils and plans, leading to inefficiencies and potential misuse of cleaning equipment.
Innovation Solution
A cleaning system comprising a cart with rollers and an external accessory device that includes a hand-actuatable interaction element for inputting information into a user application program, allowing for the processing of cleaning-related information and the execution of cleaning plans, enabling user-friendly and reliable task execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation of cleaning carts is used, then simplicity and low cost are maintained, but efficiency and reliability of cleaning task execution deteriorate
Solution Approach 1:
The patent introduces an external accessory device as an intermediary between the user and the cleaning cart system. This device includes a processor, memory storing cleaning plans, and a wireless communication interface. The accessory device receives user inputs, processes cleaning plans, and transmits control signals to the cleaning cart, thereby improving execution efficiency without requiring complex integrated systems in the cart itself.
Solution Approach 2:
The system is divided into separate functional modules: the cleaning cart with basic cleaning functions, the external accessory device for intelligence and control, and the interaction device for user input. This segmentation allows each component to be optimized independently, maintaining simplicity of individual parts while achieving high overall efficiency through their coordinated operation.
2Reliability
If comprehensive cleaning plans and inventory management are implemented, then reliability and precision of task execution are improved, but ease of operation deteriorates due to increased complexity
Solution Approach 1:
The system implements self-service through automatic inventory management and task execution monitoring. The processor in the accessory device automatically tracks cleaning utensil inventory, verifies task completion, and manages supply levels without requiring manual intervention. This automation maintains high reliability while reducing the operational burden on users.
Solution Approach 2:
The system incorporates feedback mechanisms where the interaction device provides real-time status information about cleaning task progress, inventory levels, and system state. The processor receives user inputs and provides confirmation feedback, allowing users to monitor and control the system easily while maintaining reliable execution through continuous feedback loops.
3Reliability
If authorization management and inventory control are added, then misuse prevention is improved, but device complexity increases
Solution Approach 1:
The external accessory device serves multiple functions: it manages authorization, controls inventory, processes cleaning plans, and provides user interface functionality. By consolidating these diverse functions into a single universal device, the system achieves comprehensive misuse prevention and reliable task execution without proportionally increasing overall system complexity.
