Mobile Carpet Washing Line With Integrated Rapid Air Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carpet washing technologies require separate equipment for wet and dry cleaning, and are typically stationary, making it impossible to quickly wash and dry carpets on-site without the need for replacement carpets.
Innovation Solution
A transportable carpet washing equipment that integrates wet and dry cleaning capabilities, using a conveyor system, washing units with brushes, and high-pressure air blowers to dry carpets efficiently, allowing for on-site washing and drying within 5 to 20 minutes without intermediate storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate equipment is used for wet and dry cleaning, then cleaning effectiveness is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines wet cleaning and drying functions into a single integrated carpet washing machine. The wet cleaning unit and drying unit are merged in one device, eliminating the need for separate equipment while maintaining both cleaning effectiveness and drying capability.
Solution Approach 2:
The carpet washing machine is designed as a multi-functional device that performs both wet cleaning and drying operations. The single equipment handles multiple cleaning stages (wet cleaning, rinsing, and drying) that traditionally required separate machines, making the device universal for complete carpet care.
2Productivity
If stationary carpet washing equipment is used, then cleaning capacity is improved, but mobility and on-site service capability are lost
Solution Approach 1:
The carpet washing machine is designed with mobile characteristics, allowing it to be transported to different locations for on-site service. The equipment maintains its cleaning capacity while gaining the dynamic capability to move between customer premises, enabling flexible deployment without requiring fixed installation.
3Reliability
If traditional drying methods are used, then moisture removal is achieved, but drying time is too long requiring replacement carpets
Solution Approach 1:
The drying unit uses compressed air (pneumatic system) to rapidly remove moisture from the carpet. High-pressure air streams blow through the carpet pile, efficiently evaporating and removing water much faster than traditional air drying methods, reducing drying time to under 20 minutes.
Solution Approach 2:
The drying process utilizes controlled changes in air pressure and flow parameters to accelerate moisture removal. By adjusting the compressed air pressure and flow rate, the system optimizes drying speed while ensuring thorough moisture removal, achieving fast drying without sacrificing effectiveness.
4Loss of time
If fast drying is implemented, then service time is reduced, but energy consumption increases
Solution Approach 1:
The system recovers and reuses water during the cleaning process. The water collected from the wet cleaning stage is utilized in subsequent drying operations, reducing the need for additional energy-intensive water heating and processing. This recovery approach minimizes energy consumption while maintaining fast service times.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables fast and efficient on-site carpet washing and drying, eliminating the need for replacement carpets by using closed water circulation and self-sufficiency in energy and water, ensuring carpets are returned to customers quickly and without visible moisture.
Implementation Method 1
the blowing apparatus being able to blow compressed air with a pressure of 2-15 bars, preferably 2-6 bars onto the pile side of the carpet
Implementation Method 2
Said washing unit comprises also at least one brush and means for moving the carpet

AI summary
A method to wash and dry carpets and an in situ carpet washing service is described. The service uses transportable equipment comprising in one frame a washing unit, a drying unit and conveyor for transferring the carpet between the washing and drying units of the equipment, a control unit for controlling the operation of the equipment, and means for receiving production goods to the equipment. In the equipment the carpet is transported from a first feeding end, through the washing and drying units to the second receiving end at a constant speed such that the washing and drying steps can be completed in less than 20 minutes and the tack free carpet can be returned to the customer without a need of a replacement carpet.
